The Dispatch Queue - An Alternative Means of Accounting for External Costs? [28Sep11] - 0 views

  • Without much going on recently that hasn’t been covered by other blog posts, I’d like to explore a topic not specifically tied to nuclear power or to activities currently going on in Washington, D.C. It involves an idea I have about a possible alternative means of having the electricity market account for the public health and environmental costs of various energy sources, and encouraging the development and use of cleaner sources (including nuclear) without requiring legislation. Given the failure of Congress to take action on global warming, as well as environmental issues in general, non-legislative approaches to accomplishing environmental goals may be necessary. The Problem
  • One may say that the best response would be to significantly tighten pollution regulations, perhaps to the point where no sources have significant external costs. There are problems with this approach, however, above and beyond the fact that the energy industry has (and will?) successfully blocked the legislation that would be required. Significant tightening of regulations raises issues such as how expensive compliance will be, and whether or not viable alternative (cleaner) sources would be available. The beauty of simply placing a cost (or tax) on pollution that reflects its costs to public health and the environment is that those issues need not be addressed. The market just decides between sources based on the true, overall cost of each, resulting in the minimum overall (economic + environmental) cost-generation portfolio
  • The above reasoning is what led to policies like cap-and-trade or a CO2 emissions tax being proposed as a solution for the global warming problem. This has not flown politically, however. Policies that attempt to have external costs included in the market cost of energy have been labeled a “tax increase.” This is particularly true given that the associated pollution taxes (or emissions credit costs) would have largely gone to the government.

  • One final idea, which does not involve money going to or from government, is simply requiring that cleaner sources provide a certain fraction of our overall power generation. The many state Renewable Portfolio Standards (that do not include nuclear) and the Clean Energy Standard being considered by Congress and the Obama administration (which does include nuclear) are examples of this policy. While better than nothing, such policies are not ideal in that they are crude, and don’t involve a quantitative incentive based on real external costs. An energy source is either defined as “clean,” or it is not. Note that the definition of “clean” would be decided politically, as opposed to objectively based on tangible external costs determined by scientific studies (nuclear’s exclusion from state Renewable Portfolio Standards policies being one outrageous example). Finally, there is the fact that any such policy would require legislation.
  • Well, if we can’t tax pollution, how about encouraging the use of clean sources by giving them subsidies? This has proved to be more popular so far, but this idea has also recently run into trouble, given the current situation with the budget deficit and national debt. Events like the Solyndra bankruptcy have put government clean energy subsidies even more on the defensive. Thus, it seems that neither policies involving money flowing to the government nor policies involving money flowing from the government are politically viable at this point.
  • All of the above begs the question whether there is a policy available that will encourage the use of cleaner energy sources that is revenue-neutral (i.e., does not involve money flowing to or from the government), does not involve the outright (political) selection of certain energy sources over others, and does not require legislation. Enter the Dispatch Queue
  • There must be enough power plants in a given region to meet the maximum load (or demand) expected to occur. In fact, total generation capacity must exceed maximum demand by a specified “reserve margin,” to address the possibility of a plant going offline, or other possible considerations. Due to the fact that demand varies significantly with time, a significant fraction of the generation capacity remains offline, some or most of the time. The dispatch queue is a means by which utilities, or independent regional grid operators, decide which power plants will operate in order to meet demand at any given instant. A good discussion of dispatch queues and how they operate can be found in this Department of Energy report.
  • The general goal of the methodology used to set the dispatch queue order is to minimize overall generation cost, while staying in compliance with all federal or state laws (environmental rules, etc.). This is done by placing the power plants with the lowest “variable” cost first in the queue. Plants with the highest “variable” cost are placed last. The “variable” cost of a plant represents how much more it costs to operate the plant than it costs to leave it idle (i.e., it includes the fuel cost and maintenance costs that arise from operation, but does not include the plant capital cost, personnel costs, or any fixed maintenance costs). Thus, one starts with the least expensive plants, and moves up (in cost) until generation meets demand. The remaining, more expensive plants are not fired up. This ensures that the lowest-operating-cost set of plants is used to meet demand at any given time
  • As far as who makes the decisions is concerned, in many cases the local utility itself runs the dispatch for its own service territory. In most of the United States, however, there is a large regional grid (covering several utilities) that is operated by an Independent System Operator (ISO) or Regional Transmission Organization (RTO), and those organizations, which are independent of the utilities, set the dispatch queue for the region. The Idea
  • As discussed above, a plant’s place in the dispatch queue is based upon variable cost, with the lowest variable cost plants being first in the queue. As discussed in the DOE report, all the dispatch queues in the country base the dispatch order almost entirely on variable cost, with the only possible exceptions being issues related to maximizing grid reliability. What if the plant dispatch methodology were revised so that environmental costs were also considered? Ideally, the public health and environmental costs would be objectively and scientifically determined and cast in terms of an equivalent economic cost (as has been done in many scientific studies such as the ExternE study referenced earlier). The calculated external cost would be added to a plant’s variable cost, and its place in the dispatch queue would be adjusted accordingly. The net effect would be that dirtier plants would be run much less often, resulting in greatly reduced pollution.
  • This could have a huge impact in the United States, especially at the current time. Currently, natural gas prices are so low that the variable costs of combine-cycle natural gas plants are not much higher than those of coal plants, even without considering environmental impacts. Also, there is a large amount of natural gas generation capacity sitting idle.
  • More specifically, if dispatch queue ordering methods were revised to even place a small (economic) weight on environmental costs, there would be a large switch from coal to gas generation, with coal plants (especially the older, dirtier ones) moving to the back of the dispatch queue, and only running very rarely (at times of very high demand). The specific idea of putting gas plants ahead of coal plants in the dispatch queue is being discussed by others.
  • The beauty of this idea is that it does not involve any type of tax or government subsidy. It is revenue neutral. Also, depending on the specifics of how it’s implemented, it can be quantitative in nature, with environmental costs of various power plants being objectively weighed, as opposed certain sources simply being chosen, by government/political fiat, over others. It also may not require legislation (see below). Finally, dispatch queues and their policies and methods are a rather arcane subject and are generally below the political radar (many folks haven’t even heard of them). Thus, this approach may allow the nation’s environmental goals to be (quietly) met without causing a political uproar. It could allow policy makers to do the right thing without paying too high of a political cost.
  • Questions/Issues The DOE report does mention some examples of dispatch queue methods factoring in issues other than just the variable cost. It is fairly common for issues of grid reliability to be considered. Also, compliance with federal or state environmental requirements can have some impacts. Examples of such laws include limits on the hours of operation for certain polluting facilities, or state requirements that a “renewable” facility generate a certain amount of power over the year. The report also discusses the possibility of favoring more fuel efficient gas plants over less efficient ones in the queue, even if using the less efficient plants at that moment would have cost less, in order to save natural gas. Thus, the report does discuss deviations from the pure cost model, to consider things like environmental impact and resource conservation.
  • I could not ascertain from the DOE report, however, what legal authorities govern the entities that make the plant dispatch decisions (i.e., the ISOs and RTOs), and what types of action would be required in order to change the dispatch methodology (e.g., whether legislation would be required). The DOE report was a study that was called for by the Energy Policy Act of 2005, which implies that its conclusions would be considered in future congressional legislation. I could not tell from reading the report if the lowest cost (only) method of dispatch is actually enshrined somewhere in state or federal law. If so, the changes I’m proposing would require legislation, of course.
  • The DOE report states that in some regions the local utility runs the dispatch queue itself. In the case of the larger grids run by the ISOs and RTOs (which cover most of the country), the report implies that those entities are heavily influenced, if not governed, by the Federal Energy Regulatory Commission (FERC), which is part of the executive branch of the federal government. In the case of utility-run dispatch queues, it seems that nothing short of new regulations (on pollution limits, or direct guidance on dispatch queue ordering) would result in a change in dispatch policy. Whereas reducing cost and maximizing grid reliability would be directly in the utility’s interest, favoring cleaner generation sources in the queue would not, unless it is driven by regulations. Thus, in this case, legislation would probably be necessary, although it’s conceivable that the EPA could act (like it’s about to on CO2).
  • In the case of the large grids run by ISOs and RTOs, it’s possible that such a change in dispatch methodology could be made by the federal executive branch, if indeed the FERC has the power to mandate such a change
  • Effect on Nuclear With respect to the impacts of including environmental costs in plant dispatch order determination, I’ve mainly discussed the effects on gas vs. coal. Indeed, a switch from coal to gas would be the main impact of such a policy change. As for nuclear, as well as renewables, the direct/immediate impact would be minimal. That is because both nuclear and renewable sources have high capital costs but very low variable costs. They also have very low environmental impacts; much lower than those of coal or gas. Thus, they will remain at the front of the dispatch queue, ahead of both coal and gas.

German Nuclear Decommissioning and Renewables Build-Out [23Oct11] - 0 views

  • Germany will be redirecting its economy towards renewable energy, because of the political decision to decommission its nuclear plants, triggered by the Fukushima event in Japan and subsequent public opposition to nuclear energy. Germany's decision would make achieving its 2020 CO2 emission reduction targets more difficult.   To achieve the CO2 emissions reduction targets and replace nuclear energy, renewable energy would need to scale up from 17% in 2010 to 57% of total electricity generation of 603 TWh in 2020, according to a study by The Breakthrough Institute. As electricity generation was 603 TWh in 2010, increased energy efficiency measures will be required to flat-line electricity production during the next 9 years.   Germany has 23 nuclear reactors (21.4 GW), 8 are permanently shut down (8.2 GW) and 15 (13.2 GW) will be shut down by 2022. Germany will be adding a net of 5 GW of coal plants, 5 GW of new CCGT plants and 1.4 GW of new biomass plants in future years. The CCGT plants will reduce the shortage of quick-ramping generation capacity for accommodating variable wind and solar energy to the grid.
  • Germany is planning a $14 billion build-out of transmission systems for onshore and future offshore wind energy in northern Germany and for augmented transmission with France for CO2-free hydro and nuclear energy imports to avoid any shortages.    Germany had fallen behind on transmission system construction in the north because of public opposition and is using the nuclear plant shutdown as leverage to reduce public opposition. Not only do people have to look at a multitude of 450-ft tall wind turbines, but also at thousands of 80 to 135 ft high steel structures and wires of the transmission facilities.   The $14 billion is just a minor down payment on the major grid reorganization required due to the decommissioning of the nuclear plants and the widely-dispersed build-outs of renewables. The exisitng grid is mostly large-central-plant based. 
  • This article includes the estimated capital costs of shutting down Germany's nuclear plants, reorganizing the grids of Germany and its neighbors, and building out renewables to replace the nuclear energy.    Germany’s Renewable Energy Act (EEG) in 2000, guarantees investors above-market fees for solar power for 20 years from the point of installation. In 2010, German investments in  renewables was about $41.2 billion, of which about $36.1 billion in 7,400 MW of solar systems ($4,878/kW). In 2010, German incentives for all renewables was about $17.9 billion, of which about half was for solar systems.   The average subsidy in 2010 was about ($9 billion x 1 euro/1.4 $)/12 TWh = 53.6 eurocents/kWh; no wonder solar energy is so popular in Germany. These subsidies are rolled into electric rates as fees or taxes, and will ultimately make Germany less competitive in world markets.   http://thebreakthrough.org/blog//2011/06/analysis_germanys_plan_to_phas-print.html http://mobile.bloomberg.com/news/2011-05-31/merkel-faces-achilles-heel-in-grids-to-unplug-german-nuclear.html http://www.theecologist.org/News/news_analysis/829664/revealed_how_your_country_compares_on_renewable_investment.html http://en.wikipedia.org/wiki/Solar_power_in_Germany

  • SUMMARY OF ESTIMATED CAPITAL AND OTHER COSTS   The estimated capital costs and other costs for decommissioning the nuclear plants, restoring the sites, building out renewables, wind and solar energy balancing plants, and reorganizing electric grids over 9 years are summarized below.    The capital cost and subsidy cost for the increased energy efficiency measures was not estimated, but will likely need to be well over $180 billion over 9 years, or $20 billion/yr, or $20 b/($3286 b in 2010) x 100% = 0.6% of GDP, or $250 per person per yr.     Decommission nuclear plants, restore sites: 23 @ $1 billion/plant = $23 billion Wind turbines, offshore: 53,300 MW @ $4,000,000/MW = $213.2 billion   Wind turbines, onshore: 27,900 MW @ $2,000,000/MW = $55.8 billion Wind feed-in tariff extra costs rolled into electric rates over 9 years: $200 billion  Solar systems: 82,000 MW @ $4,500,000/MW = $369 billion Solar feed-in tariff extra costs rolled into electric rates over 9 years = $250 billion. Wind and solar energy balancing plants: 25,000 MW of CCGTs @ $1,250,000/MW = $31.3 billion Reorganizing European elecric grids tied to German grids: $150 billion
  • RENEWABLE ENERGY AND ENERGY EFFICIENCY TARGETS   In September 2010 the German government announced the following targets:   Renewable electricity - 35% by 2020 and 80% by 2050 Renewable energy - 18% by 2020, 30% by 2030, and 60% by 2050 Energy efficiency - Reducing the national electricity consumption 50% below 2008 levels by 2050.  http://en.wikipedia.org/wiki/Renewable_energy_in_Germany   Germany has a target to reduce its nation-wide CO2 emissions from all sources by 40% below 1990 levels by 2020 and 80-85% below 1990 levels by 2050. That goal could be achieved, if 100% of electricity is generated by renewables, according to Mr. Flasbarth. Germany is aiming to convince the rest of Europe to follow its lead.
  • Biomass: At the end of 2010, about 5,200 MW of biomass was installed at a capital cost of about $18 billion. Biomass energy produced was 33.5 TWh, or 5.5% of production. Plans are to add 1,400 MW of biomass plants in future years which, when fully implemented, would produce about 8.6 TWh/yr.   Solar: At the end of 2010, about 17,320 MW of PV solar was installed in Germany at a capital cost of about $100 billion. PV solar energy produced was 12 TWh, or 2% of total production. The excess cost of the feed-in-tariff energy bought by utilities and rolled into the electricity costs of rate payers was about $80 billion during the past 11 years.   Most solar panels are in southern Germany (nation-wide solar CF 0.095). When skies are clear, the solar production peaks at about 7 to 10 GW. Because of insufficient capacity of transmission and quick-ramping gas turbine plants, and because curtailment is not possible, part of the solar energy, produced at a cost to the German economy of about 30 to 50 eurocent/kWh is “sold” at European spot prices of about 5 eurocent/kWh to France which has significant hydro capacity for balancing the variable solar energy. http://theenergycollective.com/willem-post/46142/impact-pv-solar-feed-tariffs-germany  
  • Wind: At the end of 2010, about 27,200 MW of onshore and offshore wind turbines was installed in Germany at a capital cost of about $50 billion. Wind energy produced was 37.5 TWh, or 6.2% of total production. The excess cost of the feed-in-tariff energy bought by utilities and rolled into electricity costs of rate payers was about $50 billion during the past 11 years.   Most wind turbines are in northern Germany. When wind speeds are higher wind curtailment of 15 to 20 percent takes place because of insufficient transmission capacity and quick-ramping gas turbine plants. The onshore wind costs the Germany economy about 12 eurocent/kWh and the offshore wind about 24 eurocent/kWh. The owners of the wind turbines are compensated for lost production.   The alternative to curtailment is to “sell” the energy at European spot prices of about 5 eurocent/kWh to Norway and Sweden which have significant hydro capacity for balancing the variable wind energy; Denmark has been doing it for about 20 years.   As Germany is very marginal for onshore wind energy (nation-wide onshore wind CF 0.167) and nearly all of the best onshore wind sites have been used up, or are off-limits due to noise/visual/environmental impacts, most of the additional wind energy will have to come from OFFSHORE facilities which produce wind energy at about 2 to 3 times the cost of onshore wind energy. http://theenergycollective.com/willem-post/61774/wind-energy-expensive
  • A 2009 study by EUtech, engineering consultants, concluded Germany will not achieve its nation-wide CO2 emissions target; the actual reduction will be less than 30%. The head of Germany's Federal Environment Agency (UBA), Jochen Flasbarth, is calling for the government to improve CO2 reduction programs to achieve targets. http://www.spiegel.de/international/germany/0,1518,644677,00.html   GERMAN RENEWABLE ENERGY TO-DATE   Germany announced it had 17% of its electrical energy from renewables in 2010; it was 6.3% in 2000. The sources were 6.2% wind, 5.5% biomass, 3.2% hydro and 2.0% solar. Electricity consumption in 2010 was 603 TWh (production) - 60 TWh (assumed losses) = 543 TWh http://www.volker-quaschning.de/datserv/ren-Strom-D/index_e.php  
  • Hydro: At the end of 2010, about 4,700 MW of hydro was installed. Hydro energy produced was 19.5 TWh, or 3.2% of production. Hydro growth has been stagnant during the past 20 years. See below website.   As it took about $150 billion of direct investment, plus about $130 billion excess energy cost during the past 11 years to achieve 8.2% of total production from solar and wind energy, and assuming hydro will continue to have little growth, as was the case during the past 20 years (almost all hydro sites have been used up), then nearly all of the renewables growth by 2020 will be mostly from wind, with the remainder from solar and biomass. http://www.renewableenergyworld.com/rea/news/article/2011/03/new-record-for-german-renewable-energy-in-2010??cmpid=WNL-Wednesday-March30-2011   Wind and Solar Energy Depend on Gas: Wind and solar energy is variable and intermittent. This requires quick-ramping gas turbine plants to operate at part-load and quickly ramp up with wind energy ebbs and quickly ramp down with wind energy surges; this happens about 100 to 200 times a day resulting in increased wear and tear. Such operation is very inefficient for gas turbines causing them to use extra fuel/kWh and emit extra CO2/kWh that mostly offset the claimed fuel and CO2 reductions due to wind energy. http://theenergycollective.com/willem-post/64492/wind-energy-reduces-co2-emissions-few-percent  
  • Wind energy is often sold to the public as making a nation energy independent, but Germany will be buying gas mostly from Russia supplied via the newly constructed pipeline under the Baltic Sea from St. Petersburg to Germany, bypassing Poland.   GERMANY WITHOUT NUCLEAR ENERGY   A study performed by The Breakthrough Institute concluded to achieve the 40% CO2 emissions reduction target and the decommissioning of 21,400 MW of nuclear power plants by 2022, Germany’s electrical energy mix would have to change from 60% fossil, 23% nuclear and 17% renewables in 2010 to 43% fossil and 57% renewables by 2020. This will require a build-out of renewables, reorganization of Europe’s electric grids (Europe’s concurrence will be needed) and acceleration of energy efficiency measures.   According to The Breakthrough Institite, Germany would have to reduce its total electricity consumption by about 22% of current 2020 projections AND achieve its target for 35% electricity generated from renewables by 2020. This would require increased energy efficiency measures to effect an average annual decrease of the electricity consumption/GDP ratio of 3.92% per year, significantly greater than the 1.47% per year decrease assumed by the IEA's BAU forecasts which is based on projected German GDP growth and current German efficiency policies.
  • The Breakthrough Institute projections are based on electricity consumption of 544  and 532 TWh  in 2008 and 2020, respectively; the corresponding production is 604 TWh in 2008 and 592 TWh in 2020.   http://thebreakthrough.org/blog//2011/06/analysis_germanys_plan_to_phas-print.html http://www.iea.org/textbase/nppdf/free/2007/germany2007.pdf   Build-out of Wind Energy: If it is assumed the current wind to solar energy ratio is maintained at 3 to 1, the wind energy build-out will be 80% offshore and 20% onshore, and the electricity production will be 592 TWh, then the estimated capital cost of the offshore wind turbines will be [{0.57 (all renewables) - 0.11 (assumed biomass + hydro)} x 592 TWh x 3/4] x 0.8 offshore/(8,760 hr/yr x average CF 0.35) = 0.0533 TW offshore wind turbines @ $4 trillion/TW = $213 billion and of the onshore wind turbines will be [{0.57 (all renewables) - 0.11 (assumed biomass + hydro)} x 592 TWh x 3/4] x 0.2 onshore/(8,760 hr/yr x average CF 0.167) = 0.279 TW of wind turbines @ $2 trillion/TW = $56 billion, for a total of $272 billion. The feed in tariff subsidy for 9 years, if maintained similar to existing subsidies to attract adequate capital, will be about $150 billion offshore + $50 billion onshore, for a total of $200 billion.    
  • Note: The onshore build-out will at least double Germany’s existing onshore wind turbine capacity, plus required transmission systems; i.e., significant niose, environmental and visual impacts over large areas.   Recent studies, based on measured, real-time, 1/4-hour grid operations data sets of the Irish, Colorado and Texas grids, show wind energy does little to reduce CO2 emissions. Such data sets became available during the past 2 to 3 years. Prior studies, based on assumptions, estimates, modeling scenarios, and statistics, etc., significantly overstate CO2 reductions.  http://theenergycollective.com/willem-post/64492/wind-energy-reduces-co2-emissions-few-percent   Build-out of PV Solar Energy: The estimated capital cost of the PV solar capacity will be [{0.57 (all renewables) - 0.11 (assumed biomass + hydro)} x 592 TWh x 1/4]/(8,760 hr/yr x average CF 0.095) = 0.082 TW @ $4.5 trillion/TW = $369 billion. The feed in tariff subsidy, if maintained similar to existing subsidies to attract adequate capital, will be about $250 billion.   Reorganizating Electric Grids: For GW reasons, a self-balancing grid system is needed to minimize CO2 emissions from gas-fired CCGT balancing plants. One way to implement it is to enhance the interconnections of the national grids with European-wide HVDC overlay systems (owning+O&M costs, including transmission losses), and with European-wide selective curtailment of wind energy, and with European-wide demand management and with pumped hydro storage capacity. These measures will reduce, but not eliminate, the need for balancing energy, at greater wind energy penetrations during high-windspeed weather conditions, as frequently occur in Iberia (Spain/Portugal).  
  • European-wide agreement is needed, the capital cost will be in excess of $150 billion and the adverse impacts on quality of life (noise, visuals, psychological), property values and the environment will be significant over large areas.    Other Capital Costs: The capacity of the quick-ramping CCGT balancing plants was estimated at 25,000 MW; their capital cost is about 25,000 MW x $1,250,000/MW = $31.3 billion. The capital costs of decommissioning and restoring the sites of the 23 nuclear plants will be about $23 billion.   Increased Energy Efficiency: Increased energy efficiency would be more attractive than major build-outs of renewables, because it provides the quickest and biggest "bang for the buck", AND it is invisible, AND it does not make noise, AND it has minimal environmental impact, AND it usually reduces at least 3 times the CO2 per invested dollar, AND it usually creates at least 3 times the jobs per invested dollar, AND it usually creates at least 3 times the energy reduction per invested dollar, AND it does all this without public resistance and controversy.   Rebound, i.e., people going back to old habits of wasting energy, is a concept fostered by the PR of proponents of conspicuous consumption who make money on such consumption. People with little money love their cars getting 35-40 mpg, love getting small electric and heating bills. The rebound is mostly among people who do not care about such bills.
  • A MORE RATIONAL APPROACH   Global warming is a given for many decades, because the fast-growing large economies of the non-OECD nations will have energy consumption growth far outpacing the energy consumption growth of the slow-growing economies of the OECD nations, no matter what these OECD nations do regarding reducing CO2 emissions of their economies.   It is best to PREPARE for the inevitable additional GW by requiring people to move away from flood-prone areas (unless these areas are effectively protected, as in the Netherlands), requiring new  houses and other buildings to be constructed to a standard such as the Passivhaus standard* (such buildings stay cool in summer and warm in winter and use 80 to 90 percent less energy than standard buildings), and requiring the use of new cars that get at least 50 mpg, and rearranging the world's societies for minimal energy consumption; making them walking/bicycling-friendly would be a good start.   If a nation, such as the US, does not do this, the (owning + O&M) costs of its economy will become so excessive (rising resource prices, increased damage and disruptions from weather events) that its goods and services will become less competitive and an increasing percentage of its population will not be able to afford a decent living standard in such a society.   For example: In the US, the median annual household income (inflation-adjusted) was $49,445, a decline of 7% since 2000. As the world’s population increases to about 10 billion by 2050, a triage-style rationing of resources will become more prevalent. http://www.usatoday.com/news/nation/story/2011-09-13/census-household-income/50383882/1
  • * A 2-year-old addition to my house is built to near-Passivhaus standards; its heating system consists of a thermostatically-controlled 1 kW electric heater, set at 500 W, that cycles on/off on the coldest days for less than 100 hours/yr. The addition looks inside and out entirely like standard construction. http://theenergycollective.com/willem-post/46652/reducing-energy-use-houses

Did Fukushima kill the nuclear renaissance No, that renaissance died right here at home... - 0 views

shared by D'coda Dcoda on 04 Nov 11 - No Cached
  • In the aftermath of the Fukushima Daiichi nuclear disaster in Japan, many wondered what the event’s impact would be on the nuclear renaissance in the United States. Those who follow the nuclear industry didn’t need eight months of hindsight to give an answer: what nuclear renaissance? The outlook for U.S. nuclear power has worsened considerably in the past five years. Where once there were plans for new reactors at more than 30 different sites, today there are only five, and even those planned reactors might disappear. Only one is actually under construction, and to credit the industry with breaking ground on a new reactor is overstating its prospects. However, none of this gloom is the result of Japan’s tsunami. On the eve of the Tohoku earthquake, U.S. nuclear power looked just as moribund as it is today. The cause of this decline is not renewed concerns about safety, or even that old red herring, waste disposal — instead, it is simple economics. Other technologies, particularly natural gas, offer much cheaper power than nuclear both today and in the foreseeable future.
  • In 2009, the MIT Future of Nuclear Power study released an update to its 2003 estimate of the costs of nuclear power. Estimating a capital cost of $4,000/kW and a fuel cost of $0.67/MMBtu, the study’s authors projected a cost of new nuclear power of 6.6 cents/kWh. Using the same modeling approach, the cost of electricity from a natural gas plant with capital costs of $850/kW and fuel costs of $5.16/MMBtu would be 4.4 cents/kWh. What’s worse, the estimate of 6.6 cents/kWh assumes that nuclear power is able to secure financing at the same interest rate as natural gas plants. In reality, credit markets assign a significant risk premium to nuclear power, bringing its total levelized cost of electricity to 8.4 cents/kWh, nearly twice the cost of natural gas power. Unless the capital costs of new nuclear power plants turn out to be significantly less than what experts expect, or natural gas prices rise considerably in the near future, there is little reason to believe that any new nuclear plants will be built without significant subsidies. This is not to say that nuclear power could not make a comeback within the next 10 to 20 years. But before nuclear can once again be considered a credible competitor to fossil fuels, four changes must happen.
  • The second problem facing nuclear power is its high borrowing costs. To some extent, this problem is a natural consequence of nuclear power plants taking a longer time to build than natural gas plants and having a much higher construction risk (the capital cost of natural gas plants is well-established relative to that of nuclear power). And likewise, to some extent, this problem might resolve itself over time, both as the completion of nuclear plants helps nail down the true capital cost of nuclear power, and as vendors add smaller, modular reactor designs to their list of offerings. But much of the reason behind the high interest rates on loans to nuclear construction is that the industry is scoring an own-goal. In the current relationship between utilities and reactor vendors, utilities are asked to absorb all of the costs of a vendor’s overruns — if a reactor ends up costing a couple billion dollars more than the vendor quotes, it’s the utility that is expected to make up the difference.

  • This is terrifying for a utility’s creditors. The largest utilities in the United States have market capitalizations in the area of $30 billion, while most hover closer to $5 billion. If a nuclear project should fail, the utility might go completely bankrupt, leaving nothing to those foolish enough to lend them money. Accordingly, nuclear projects face higher borrowing costs than other electric projects. It doesn’t have to be this way — if reactor vendors and construction companies helped share the project risks posed by nuclear plants, borrowing costs would be lower. It is also possible for the U.S. government to shoulder some of the risk — but after Solyndra, few legislators have an appetite for letting energy companies push their risks onto the taxpayer.
  • Next, the United States is going to have to adopt some form of carbon tax on electricity generation, or offer a comparable subsidy to the nuclear industry. An appropriately sized carbon tax of $20/ton CO2 would raise the cost of natural-gas-generated electricity by 0.7 cents/kWh, while having a negligible impact on nuclear power
  • And finally, the nuclear industry is just going to have to catch some luck and see natural gas prices rise. That’s a tall order, given the new resources being opened up by hydraulic fracturing and the slowed consumption of natural gas brought about by the recession. But it’s not entirely outside of the realm of possibility — the futures market for natural gas has been wrong before.
  • Nuclear power is down, but not out. With a proper R&D focus, good business practices, appropriate policy, and a little luck, the gulf that separates nuclear power from its competitors may yet be bridged.

CPS must die [24Oct07} - 0 views

  • Collectively, Texas eats more energy than any other state, according to the U.S. Department of Energy. We’re fifth in the country when it comes to our per-capita energy intake — about 532 million British Thermal Units per year. A British Thermal Unit, or Btu, is like a little “bite” of energy. Imagine a wooden match burning and you’ve got a Btu on a stick. Of course, the consumption is with reason. Texas, home to a quarter of the U.S. domestic oil reserves, is also bulging with the second-highest population and a serious petrochemical industry. In recent years, we managed to turn ourselves into the country’s top producer of wind energy. Despite all the chest-thumping that goes on in these parts about those West Texas wind farms (hoist that foam finger!), we are still among the worst in how we use that energy. Though not technically “Southern,” Texans guzzle energy like true rednecks. Each of our homes use, on average, about 14,400 kilowatt hours per year, according to the U.S. Energy Information Administration. It doesn’t all have to do with the A/C, either. Arizonans, generally agreed to be sharing the heat, typically use about 12,000 kWh a year; New Mexicans cruise in at an annual 7,200 kWh. Don’t even get me started on California’s mere 6,000 kWh/year figure.
  • Let’s break down that kilowatt-hour thing. A watt is the energy of one candle burning down. (You didn’t put those matches away, did you?) A kilowatt is a thousand burnin’ candles. And a kilowatt hour? I think you can take it from there. We’re wide about the middle in Bexar, too. The average CPS customer used 1,538 kilowatt hours this June when the state average was 1,149 kWh, according to ERCOT. Compare that with Austin residents’ 1,175 kWh and San Marcos residents’ 1,130 kWh, and you start to see something is wrong. So, we’re wasteful. So what? For one, we can’t afford to be. Maybe back when James Dean was lusting under a fountain of crude we had if not reason, an excuse. But in the 1990s Texas became a net importer of energy for the first time. It’s become a habit, putting us behind the curve when it comes to preparing for that tightening energy crush. We all know what happens when growing demand meets an increasingly scarce resource … costs go up. As the pressure drop hits San Anto, there are exactly two ways forward. One is to build another massively expensive power plant. The other is to transform the whole frickin’ city into a de-facto power plant, where energy is used as efficiently as possible and blackouts simply don’t occur.
  • Consider, South Texas Project Plants 1&2, which send us almost 40 percent of our power, were supposed to cost $974 million. The final cost on that pair ended up at $5.5 billion. If the planned STP expansion follows the same inflationary trajectory, the price tag would wind up over $30 billion. Applications for the Matagorda County plants were first filed with the Atomic Energy Commission in 1974. Building began two years later. However, in 1983 there was still no plant, and Austin, a minority partner in the project, sued Houston Power & Lighting for mismanagement in an attempt to get out of the deal. (Though they tried to sell their share several years ago, the city of Austin remains a 16-percent partner, though they have chosen not to commit to current expansion plans).

  • CPS didn’t just pull nukes out of a hat when it went looking for energy options. CEO Milton Lee may be intellectually lazy, but he’s not stupid. Seeking to fulfill the cheap power mandate in San Antonio and beyond (CPS territory covers 1,566 square miles, reaching past Bexar County into Atascosa, Bandera, Comal, Guadalupe, Kendall, Medina, and Wilson counties), staff laid natural gas, coal, renewables and conservation, and nuclear side-by-side and proclaimed nukes triumphant. Coal is cheap upfront, but it’s helplessly foul; natural gas, approaching the price of whiskey, is out; and green solutions just aren’t ready, we’re told. The 42-member Nuclear Expansion Analysis Team, or NEAT, proclaimed “nuclear is the lowest overall risk considering possible costs and risks associated with it as compared to the alternatives.” Hear those crickets chirping?
  • NEAT members would hold more than a half-dozen closed-door meetings before the San Antonio City Council got a private briefing in September. When the CPS board assembled October 1 to vote the NRG partnership up or down, CPS executives had already joined the application pending with the U.S. Nuclear Regulatory Commission. A Supplemental Participation Agreement allowed NRG to move quickly in hopes of cashing in on federal incentives while giving San Antonio time to gather its thoughts. That proved not too difficult. Staff spoke of “overwhelming support” from the Citizen’s Advisory Board and easy relations with City staff. “So far, we haven’t seen any fatal flaws in our analysis,” said Mike Kotera, executive vice president of energy development for CPS. With boardmember and Mayor Phil Hardberger still in China inspecting things presumably Chinese, the vote was reset for October 29.
  • No one at the meeting asked about cost, though the board did request a month-by-month analysis of the fiasco that has been the South Texas Project 1&2 to be delivered at Monday’s meeting. When asked privately about cost, several CPS officers said they did not know what the plants would run, and the figure — if it were known — would not be public since it is the subject of contract negotiations. “We don’t know yet,” said Bob McCullough, director of CPS’s corporate communications. “We are not making the commitment to build the plant. We’re not sure at this point we really understand what it’s going to cost.” The $206 million outlay the board will consider on Monday is not to build the pair of 1,300-megawatt, Westinghouse Advanced Boiling Water Reactors. It is also not a contract to purchase power, McCullough said. It is merely to hold a place in line for that power.
  • It’s likely that we would come on a recurring basis back to the board to keep them apprised of where we are and also the decision of whether or not we think it makes sense for us to go forward,” said Larry Blaylock, director of CPS’s Nuclear Oversight & Development. So, at what point will the total cost of the new plants become transparent to taxpayers? CPS doesn’t have that answer. “At this point, it looks like in order to meet our load growth, nuclear looks like our lowest-risk choice and we think it’s worth spending some money to make sure we hold that place in line,” said Mark Werner, director of Energy Market Operations.
  • Another $10 million request for “other new nuclear project opportunities” will also come to the board Monday. That request summons to mind a March meeting between CPS officials and Exelon Energy reps, followed by a Spurs playoff game. Chicago-based Exelon, currently being sued in Illinois for allegedly releasing millions of gallons of radioactive wastewater beneath an Illinois plant, has its own nuclear ambitions for Texas. South Texas Project The White House champions nuclear, and strong tax breaks and subsidies await those early applicants. Whether CPS qualifies for those millions remains to be seen. We can only hope.
  • CPS has opted for the Super Honkin’ Utility model. Not only that — quivering on the brink of what could be a substantial efficiency program, CPS took a leap into our unflattering past when it announced it hopes to double our nuclear “portfolio” by building two new nuke plants in Matagorda County. The utility joined New Jersey-based NRG Energy in a permit application that could fracture an almost 30-year moratorium on nuclear power plant creation in the U.S.
  • After Unit 1 came online in 1988, it had to be shut down after water-pump shaft seared off in May, showering debris “all over the place,” according to Nucleonics Week. The next month two breakers failed during a test of backup power, leading to an explosion that sheared off a steam-generator pump and shot the shaft into the station yard. After the second unit went online the next year, there were a series of fires and failures leading to a half-million-dollar federal fine in 1993 against Houston Power. Then the plant went offline for 14 months. Not the glorious launch the partnership had hoped for. Today, CPS officials still do not know how much STP has cost the city, though they insist overall it has been a boon worth billions. “It’s not a cut-and-dried analysis. We’re doing what we can to try to put that in terms that someone could share and that’s a chore,” said spokesman McCollough. CPS has appealed numerous Open Records requests by the Current to the state Attorney General. The utility argues that despite being owned by the City they are not required to reveal, for instance, how much it may cost to build a plant or even how much pollution a plant generates, since the electricity market is a competitive field.
  • How do we usher in this new utopia of decentralized power? First, we have to kill CPS and bury it — or the model it is run on, anyway. What we resurrect in its place must have sustainability as its cornerstone, meaning that the efficiency standards the City and the utility have been reaching for must be rapidly eclipsed. Not only are new plants not the solution, they actively misdirect needed dollars away from the answer. Whether we commit $500 million to build a new-fangled “clean-coal” power plant or choose to feed multiple billions into a nuclear quagmire, we’re eliminating the most plausible option we have: rapid decentralization.
  • A 2003 study at the Massachusetts Institute of Technology estimates the cost of nuclear power to exceed that of both coal and natural gas. A U.S. Energy Information Administration report last year found that will still be the case when and if new plants come online in the next decade. If ratepayers don’t pay going in with nuclear, they can bet on paying on the way out, when virtually the entire power plant must be disposed of as costly radioactive waste. The federal government’s inability to develop a repository for the tens of thousands of tons of nuclear waste means reactors across the country are storing spent fuel in onsite holding ponds. It is unclear if the waste’s lethality and tens of thousands of years of radioactivity were factored into NEAT’s glowing analysis.
  • The federal dump choice, Nevada’s Yucca Mountain, is expected to cost taxpayers more than $60 billion. If it opens, Yucca will be full by the time STP 3&4 are finished, requiring another federal dump and another trainload of greenbacks. Just the cost of Yucca’s fence would set you back. Add the price of replacing a chain-link fence around, let’s say, a 100-acre waste site. Now figure you’re gonna do that every 50 years for 10,000 years or more. Security guards cost extra. That is not to say that the city should skip back to the coal mine. Thankfully, we don’t need nukes or coal, according to the American Council for an Energy-Efficient Economy, a D.C.-based non-profit that champions energy efficiency. A collection of reports released this year argue that a combination of ramped-up efficiency programs, construction of numerous “combined heat and power” facilities, and installation of on-site renewable energy resources would allow the state to avoid building new power plants. Texas could save $73 billion in electric generation costs by spending $50 billion between now and 2023 on such programs, according to the research group. The group also claims the efficiency revolution would even be good for the economy, creating 38,300 jobs. If ACEEE is even mostly right, plans to start siphoning millions into a nuclear reservoir look none too inspired.
  • To jump tracks will take a major conversion experience inside CPS and City Hall, a turning from the traditional model of towering plants, reels of transmission line, and jillions of dependent consumers. CPS must “decentralize” itself, as cities as close as Austin and as far away as Seattle are doing. It’s not only economically responsible and environmentally sound, but it is the best way to protect our communities entering what is sure to be a harrowing century. Greening CPS CPS is grudgingly going greener. In 2004, a team of consultants, including Wisconsin-based KEMA Inc., hired to review CPS operations pegged the utility as a “a company in transition.” Executives interviewed didn’t understand efficiency as a business model. Even some managers tapped to implement conservation programs said such programs were about “appearing” concerned, according to KEMA’s findings.
  • While the review exposed some philosophical shortcomings, it also revealed for the first time how efficiency could transform San Antonio. It was technically possible, for instance, for CPS to cut electricity demand by 1,935 megawatts in 10 years through efficiency alone. While that would be accompanied with significant economic strain, a less-stressful scenario could still cut 1,220 megawatts in that period — eliminating 36 percent of 2014’s projected energy use. CPS’s current plans call for investing $96 million to achieve a 225-megawatt reduction by 2016. The utility plans to spend more than four times that much by 2012 upgrading pollution controls at the coal-fired J.T. Deely power plant.
  • In hopes of avoiding the construction of Spruce 2 (now being built, a marvel of cleanliness, we are assured), Citizen Oversight Committee members asked KEMA if it were possible to eliminate 500 megawatts from future demand through energy efficiency alone. KEMA reported back that, yes, indeed it was possible, but would represent an “extreme” operation and may have “unintended consequences.” Such an effort would require $620 million and include covering 90 percent of the cost of efficiency products for customers. But an interesting thing happens under such a model — the savings don’t end in 2012. They stretch on into the future. The 504 megawatts that never had to be generated in 2012 end up saving 62 new megawatts of generation in 2013 and another 53 megawatts in 2014. With a few tweaks on the efficiency model, not only can we avoid new plants, but a metaphorical flip of the switch can turn the entire city into one great big decentralized power generator.
  • Even without good financial data, the Citizen’s Advisory Board has gone along with the plan for expansion. The board would be “pennywise and pound foolish” not to, since the city is already tied to STP 1&2, said at-large member Jeannie O’Sullivan. “Yes, in the past the board of CPS had been a little bit not as for taking on a [greater] percentage of nuclear power. I don’t know what their reasons were, I think probably they didn’t have a dialogue with a lot of different people,” O’Sullivan said.
  • For this, having a City-owned utility offers an amazing opportunity and gives us the flexibility to make most of the needed changes without state or federal backing. “Really, when you start looking, there is a lot more you can do at the local level,” said Neil Elliott of the ACEEE, “because you control building codes. You control zoning. You can control siting. You can make stuff happen at the local level that the state really doesn’t have that much control of.” One of the most empowering options for homeowners is homemade energy provided by a technology like solar. While CPS has expanded into the solar incentives field this year, making it only the second utility in the state to offer rebates on solar water heaters and rooftop panels, the incentives for those programs are limited. Likewise, the $400,000 CPS is investing at the Pearl Brewery in a joint solar “project” is nice as a white tiger at a truck stop, but what is truly needed is to heavily subsidize solar across the city to help kickstart a viable solar industry in the state. The tools of energy generation, as well as the efficient use of that energy, must be spread among the home and business owners.
  • Joel Serface, with bulb-polished pate and heavy gaze, refers to himself as a “product of the oil shock” who first discovered renewables at Texas Tech’s summer “geek camp.” The possibilities stayed with him through his days as a venture capitalist in Silicon Valley and eventually led him to Austin to head the nation’s first clean-energy incubation center. Serface made his pitch at a recent Solar San Antonio breakfast by contrasting Texas with those sun-worshipping Californians. Energy prices, he says, are “going up. They’re not going down again.” That fact makes alternative energies like solar, just starting to crack the 10-cent-per-killowatt barrier, financially viable. “The question we have to solve as an economy is, ‘Do we want to be a leader in that, or do we want to allow other countries [to outpace us] and buy this back from them?’” he asked.
  • To remain an energy leader, Texas must rapidly exploit solar. Already, we are fourth down the list when it comes not only to solar generation, but also patents issued and federal research awards. Not surprisingly, California is kicking silicon dust in our face.

Economic Aspects of Nuclear Fuel Reprocessing [12Jul05] - 0 views

  • On Tuesday, July 12, the Energy Subcommittee of the House Committee on Science will hold a hearing to examine whether it would be economical for the U.S. to reprocess spent nuclear fuel and what the potential cost implications are for the nuclear power industry and for the Federal Government. This hearing is a follow-up to the June 16 Energy Subcommittee hearing that examined the status of reprocessing technologies and the impact reprocessing would have on energy efficiency, nuclear waste management, and the potential for proliferation of weapons-grade nuclear materials.
  • Dr. Richard K. Lester is the Director of the Industrial Performance Center and a Professor of Nuclear Science and Engineering at the Massachusetts Institute of Technology. He co-authored a 2003 study entitled The Future of Nuclear Power. Dr. Donald W.

  • 3. Overarching Questions  Under what conditions would reprocessing be economically competitive, compared to both nuclear power that does not include fuel reprocessing, and other sources of electric power? What major assumptions underlie these analyses?  What government subsidies might be necessary to introduce a more advanced nuclear fuel cycle (that includes reprocessing, recycling, and transmutation—''burning'' the most radioactive waste products in an advanced reactor) in the U.S.?
  • ...13 more annotations...
  • 4. Brief Overview of Nuclear Fuel Reprocessing (from June 16 hearing charter)  Nuclear reactors generate about 20 percent of the electricity used in the U.S. No new nuclear plants have been ordered in the U.S. since 1973, but there is renewed interest in nuclear energy both because it could reduce U.S. dependence on foreign oil and because it produces no greenhouse gas emissions.  One of the barriers to increased use of nuclear energy is concern about nuclear waste. Every nuclear power reactor produces approximately 20 tons of highly radioactive nuclear waste every year. Today, that waste is stored on-site at the nuclear reactors in water-filled cooling pools or, at some sites, after sufficient cooling, in dry casks above ground. About 50,000 metric tons of commercial spent fuel is being stored at 73 sites in 33 states. A recent report issued by the National Academy of Sciences concluded that this stored waste could be vulnerable to terrorist attacks.
  • Under the current plan for long-term disposal of nuclear waste, the waste from around the country would be moved to a permanent repository at Yucca Mountain in Nevada, which is now scheduled to open around 2012. The Yucca Mountain facility continues to be a subject of controversy. But even if it opened and functioned as planned, it would have only enough space to store the nuclear waste the U.S. is expected to generate by about 2010.  Consequently, there is growing interest in finding ways to reduce the quantity of nuclear waste. A number of other nations, most notably France and Japan, ''reprocess'' their nuclear waste. Reprocessing involves separating out the various components of nuclear waste so that a portion of the waste can be recycled and used again as nuclear fuel (instead of disposing of all of it). In addition to reducing the quantity of high-level nuclear waste, reprocessing makes it possible to use nuclear fuel more efficiently. With reprocessing, the same amount of nuclear fuel can generate more electricity because some components of it can be used as fuel more than once.
  • The greatest drawback of reprocessing is that current reprocessing technologies produce weapons-grade plutonium (which is one of the components of the spent fuel). Any activity that increases the availability of plutonium increases the risk of nuclear weapons proliferation.  Because of proliferation concerns, the U.S. decided in the 1970s not to engage in reprocessing. (The policy decision was reversed the following decade, but the U.S. still did not move toward reprocessing.) But the Department of Energy (DOE) has continued to fund research and development (R&D) on nuclear reprocessing technologies, including new technologies that their proponents claim would reduce the risk of proliferation from reprocessing.
  • The report accompanying H.R. 2419, the Energy and Water Development Appropriations Act for Fiscal Year 2006, which the House passed in May, directed DOE to focus research in its Advanced Fuel Cycle Initiative program on improving nuclear reprocessing technologies. The report went on to state, ''The Department shall accelerate this research in order to make a specific technology recommendation, not later than the end of fiscal year 2007, to the President and Congress on a particular reprocessing technology that should be implemented in the United States. In addition, the Department shall prepare an integrated spent fuel recycling plan for implementation beginning in fiscal year 2007, including recommendation of an advanced reprocessing technology and a competitive process to select one or more sites to develop integrated spent fuel recycling facilities.''
  • During floor debate on H.R. 2419, the House defeated an amendment that would have cut funding for research on reprocessing. In arguing for the amendment, its sponsor, Mr. Markey, explicitly raised the risks of weapons proliferation. Specifically, the amendment would have cut funding for reprocessing activities and interim storage programs by $15.5 million and shifted the funds to energy efficiency activities, effectively repudiating the report language. The amendment was defeated by a vote of 110–312.
  • But nuclear reprocessing remains controversial, even within the scientific community. In May 2005, the American Physical Society (APS) Panel on Public Affairs, issued a report, Nuclear Power and Proliferation Resistance: Securing Benefits, Limiting Risk. APS, which is the leading organization of the Nation's physicists, is on record as strongly supporting nuclear power. But the APS report takes the opposite tack of the Appropriations report, stating, ''There is no urgent need for the U.S. to initiate reprocessing or to develop additional national repositories. DOE programs should be aligned accordingly: shift the Advanced Fuel Cycle Initiative R&D away from an objective of laying the basis for a near-term reprocessing decision; increase support for proliferation-resistance R&D and technical support for institutional measures for the entire fuel cycle.''  Technological as well as policy questions remain regarding reprocessing. It is not clear whether the new reprocessing technologies that DOE is funding will be developed sufficiently by 2007 to allow the U.S. to select a technology to pursue. There is also debate about the extent to which new technologies can truly reduce the risks of proliferation.
  •  It is also unclear how selecting a reprocessing technology might relate to other pending technology decisions regarding nuclear energy. For example, the U.S. is in the midst of developing new designs for nuclear reactors under DOE's Generation IV program. Some of the potential new reactors would produce types of nuclear waste that could not be reprocessed using some of the technologies now being developed with DOE funding.
  • 5. Brief Overview of Economics of Reprocessing
  • The economics of reprocessing are hard to predict with any certainty because there are few examples around the world on which economists might base a generalized model.  Some of the major factors influencing the economic competitiveness of reprocessing are: the availability and cost of uranium, costs associated with interim storage and long-term disposal in a geologic repository, reprocessing plant construction and operating costs, and costs associated with transmutation, the process by which certain parts of the spent fuel are actively reduced in toxicity to address long-term waste management.
  • Costs associated with reducing greenhouse gas emissions from fossil fuel-powered plants could help make nuclear power, including reprocessing, economically competitive with other sources of electricity in a free market.
  •  It is not clear who would pay for reprocessing in the U.S.
  • Three recent studies have examined the economics of nuclear power. In a study completed at the Massachusetts Institute of Technology in 2003, The Future of Nuclear Power, an interdisciplinary panel, including Professor Richard Lester, looked at all aspects of nuclear power from waste management to economics to public perception. In a study requested by the Department of Energy and conducted at the University of Chicago in 2004, The Economic Future of Nuclear Power, economist Dr. Donald Jones and his colleague compared costs of future nuclear power to other sources, and briefly looked at the incremental costs of an advanced fuel cycle. In a 2003 study conducted by a panel including Matthew Bunn (a witness at the June 16 hearing) and Professor Steve Fetter, The Economics of Reprocessing vs. Direct Disposal of Spent Nuclear Fuel, the authors took a detailed look at the costs associated with an advanced fuel cycle. All three studies seem more or less to agree on cost estimates: the incremental cost of nuclear electricity to the consumer, with reprocessing, could be modest—on the order of 1–2 mills/kWh (0.1–0.2 cents per kilowatt-hour); on the other hand, this increase represents an approximate doubling (at least) of the costs attributable to spent fuel management, compared to the current fuel cycle (no reprocessing). Where they strongly disagree is on how large an impact this incremental cost will have on the competitiveness of nuclear power. The University of Chicago authors conclude that the cost of reprocessing is negligible in the big picture, where capital costs of new plants dominate all economic analyses. The other two studies take a more skeptical view—because new nuclear power would already be facing tough competition in the current market, any additional cost would further hinder the nuclear power industry, or become an unacceptable and unnecessary financial burden on the government.

The High Cost of Freedom from Fossil Fuels [10Nov11] - 0 views

shared by D'coda Dcoda on 11 Nov 11 - No Cached
  • During the 1970s and 1980s, at the peak of the nuclear reactor construction, organized groups of protestors mounted dozens of anti-nuke campaigns. They were called Chicken Littles, the establishment media generally ignored their concerns, and the nuclear industry trotted out numerous scientists and engineers from their payrolls to declare nuclear energy to be safe, clean, and inexpensive energy that could reduce America’s dependence upon foreign oil. Workers at nuclear plants are highly trained, probably far more than workers in any other industry; operating systems are closely regulated and monitored. However, problems caused by human negligence, manufacturing defects, and natural disasters have plagued the nuclear power industry for its six decades. It isn’t alerts like what happened at San Onofre that are the problem; it’s the level 3 (site area emergencies) and level 4 (general site emergencies) disasters. There have been 99 major disasters, 56 of them in the U.S., since 1952, according to a study conducted by Benjamin K. Sovacool Director of the Energy Justice Program at Institute for Energy and Environment  One-third of all Americans live within 50 miles of a nuclear plant.
  • At Windscale in northwest England, fire destroyed the core, releasing significant amounts of Iodine-131. At Rocky Flats near Denver, radioactive plutonium and tritium leaked into the environment several times over a two decade period. At Church Rock, New Mexico, more than 90 million gallons of radioactive waste poured into the Rio Puerco, directly affecting the Navajo nation. In the grounds of central and northeastern Pennsylvania, in addition to the release of radioactive Cesium-137 and Iodine-121, an excessive level of Strontium-90 was released during the Three Mile Island (TMI) meltdown in 1979, the same year as the Church Rock disaster. To keep waste tanks from overflowing with radioactive waste, the plant’s operator dumped several thousand gallons of radioactive waste into the Susquehanna River. An independent study by Dr. Steven Wing of the University of North Carolina revealed the incidence of lung cancer and leukemia downwind of the TMI meltdown within six years of the meltdown was two to ten times that of the rest of the region.
  • Although nuclear plant security is designed to protect against significant and extended forms of terrorism, the NRC believes as many as one-fourth of the 104 U.S. nuclear plants may need upgrades to withstand earthquakes and other natural disasters, according to an Associated Press investigation. About 20 percent of the world’s 442 nuclear plants are built in earthquake zones, according to data compiled by the International Atomic Energy Agency. The NRC has determined that the leading U.S. plants in the Eastern Coast in danger of being compromised by an earthquake are in the extended metropolitan areas of Boston, New York City, Philadelphia, Pittsburgh, and Chattanooga. Tenn. The highest risk, however, may be California’s San Onofre and Diablo Canyon plants, both built near major fault lines. Diablo Canyon, near San Luis Obispo, was even built by workers who misinterpreted the blueprints.

  • A Department of Energy analysis revealed the budget for 75 of the first plants was about $45 billion, but cost overruns ran that to $145 billion. The last nuclear power plant completed was the Watts Bar plant in eastern Tennessee. Construction began in 1973 and was completed in 1996. Part of the federal Tennessee Valley Authority, the Watts Bar plant cost about $8 billion to produce 1,170 mw of energy from its only reactor. Work on a second reactor was suspended in 1988 because of a lack of need for additional electricity. However, construction was resumed in 2007, with completion expected in 2013. Cost to complete the reactor, which was about 80 percent complete when work was suspended, is estimated to cost an additional $2.5 billion. The cost to build new power plants is well over $10 billion each, with a proposed cost of about $14 billion to expand the Vogtle plant near Augusta, Ga. The first two units had cost about $9 billion.
  • Added to the cost of every plant is decommissioning costs, averaging about $300 million to over $1 billion, depending upon the amount of energy the plant is designed to produce. The nuclear industry proudly points to studies that show the cost to produce energy from nuclear reactors is still less expensive than the costs from coal, gas, and oil. The industry also rightly points out that nukes produce about one-fifth all energy, with no emissions, such as those from the fossil fuels. For more than six decades, this nation essentially sold its soul for what it thought was cheap energy that may not be so cheap, and clean energy that is not so clean. It is necessary to ask the critical question. Even if there were no human, design, and manufacturing errors; even if there could be assurance there would be no accidental leaks and spills of radioactivity; even if there became a way to safely and efficiently dispose of long-term radioactive waste; even if all of this was possible, can the nation, struggling in a recession while giving subsidies to the nuclear industry, afford to build more nuclear generating plants at the expense of solar, wind, and geothermal energy?

The Latte Fallacy: German Switch to Renewables Likely to Be Expensive [28Jul11] - 0 views

  • Chancellor Angela Merkel's government insists that electricity bills will only grow modestly as a result of the nuclear energy phase-out. Experts, however, disagree, with many pointing to Berlin's massive subsidies for solar power as the culprit.
  • A pioneering spirit has taken hold in Germany, thanks to the government's radical reworking of the country's energy policies. Hardly a week goes by without the foundation being laid someplace in the country for a new solar farm, yet another biogas plant or an even bigger wind turbine. Fesseldorf, the town in northern Bavaria which just hosted Seehofer, will soon be home to one of the largest photovoltaic plants in the state.
  • The German government's plan calls for increasing the share of renewables in the country's energy mix to 35 percent by 2020. It is an ambitious goal in every respect. Not only will the current renewable energy share have to be doubled within a few years, the grid expanded and new power storage facilities installed. But Chancellor Angela Merkel's government is also somehow expecting the entire energy revolution to cost virtually nothing.

  • "According to our calculations, the cost of a kilowatt hour of electricity will go up by only one cent," says Economics Minister Philipp Rösler, head of Merkel's junior coalition partner, the Free Democrats (FDP). For an average household, this would correspond to the price of only one latte a month, says Environment Minister Norbert Röttgen, of Merkel's Christian Democrats. Germany is rapidly switching to green energy and at almost no additional cost to consumers. What conservative politician would have thought such a thing possible just a few months ago?
  • In reality, though, the official calculations have little connection to reality. According to an assessment by the Rhenish-Westphalian Institute for Economic Research (RWI), the politicians' estimate of the costs of expanding renewable sources of energy is far too low, while the environmental benefits have been systematically overstated.
  • RWI experts estimate that the cost of electricity could increase by as much as five times the government's estimate of one cent per kilowatt hour. In an internal prognosis, the semi-governmental German Energy Agency anticipates an increase of four to five cents. According to the Federation of German Consumer Organizations, the additional cost could easily amount to "five cents or more per kilowatt hour."
  • An internal estimate making the rounds at the Economics Ministry also exceeds the official announcements. It concludes that an average three-person household will pay an additional 0.5 to 1.5 cents per kilowatt hour, and up to five cents more in the mid-term. This would come to an additional cost of €175 ($250) a year. "Not exactly the price of a latte," says Manuel Frondel of the RWI.
  • The problem is the federal government's outlandish subsidies policy. Electricity customers are already paying more than €13 billion this year to subsidize renewable energy. The largest subsidies go to solar plants, which contribute relatively little to overall power generation, as well as offshore wind farms in the north, which are far away from the countries largest electricity consumers in Germany's deep south.
  • German citizens will be able to see the consequences of solar subsidization on their next electricity bill. Since the beginning of the year, consumers have been assessed a renewable energy surcharge of 3.5 cents per kilowatt hour of electricity, up from about 2 cents last year. And the cost is only going up. Since the first nuclear power plant was shut down, the price of electricity on the European Energy Exchange in Leipzig has increased by about 12 percent. Germany has gone from being a net exporter to a net importer of electricity.
  • For economic and environmental reasons, therefore, it would be best to drastically reduce solar subsidies and spend the money elsewhere, such as for a subsidy system that is not tied to any given technology. For example, wind turbines built on land are significantly more effective than solar power. They receive about the same amount of subsidy money, and yet they are already feeding about five times as much electricity into the grid. In the case of hydroelectric power plants, the relationship between subsidies and electricity generation is six times better. Biomass provides a return on subsidies that is three times as high as solar.
  • "We are dumping billions into the least effective technology," says Fritz Vahrenholt, the former environment minister for the city-state of Hamburg and now the head of utility RWE's renewable electricity subsidy Innogy.
  • "From the standpoint of the climate, every solar plant is a bad investment," says Joachim Weimann, an environmental economist at the University of Magdeburg. He has calculated that it costs about €500 to save a ton of CO2 emissions with solar power. In the case of wind energy, it costs only €150. In combination with building upgrades, the cost plummets to only €15 per ton of CO2 emissions savings.
  • Photovoltaics, in particular, is now seen as an enormous waste of money. The technology receives almost half all renewable energy subsidies, even though it makes up less than one 10th of total green electricity production. And it is unreliable -- one never knows if and when the sun will be shining
  • According to the European Network of Transmission System Operators for Electricity (ENTSOE) in Brussels, Germany now imports several million kilowatt hours of electricity from abroad every day.
  • In displays on ENTSOE computers in Brussels, countries that produce slightly more electricity than they consume are identified in yellow on the monitors, while countries dependent on imports are blue. Germany used to be one of the yellow countries, but now that seven nuclear reactors have been shut down, blue is the dominant color. The electricity that was once generated by those German nuclear power plants now comes primarily from the Czech Republic and France -- and is, of course, more expensive. The demand for electricity is expected to increase in the coming years, particularly with growing numbers of electric cars being connected to the grid as they charge their batteries.
  • Solar panels only achieve their maximum capacity in the laboratory and at optimal exposure to the sun (1,000 watts per square meter), an ideal angle of incidence (48.2 degrees) and a standardized module temperature (25 degrees Celsius, or 77 degrees Fahrenheit). Such values are rare outside the laboratory. All photovoltaic systems are inactive at night, and they also generate little electricity on winter days

Nuclear electricity: a fallen dream? [28Sep11] - 0 views

  • Nuclear power is no magic solution, argues Pervez Hoodbhoy — it's not safe, or cheap, and it leads to weapons programmes. A string of energy-starved developing countries have looked at nuclear power as the magic solution. No oil, no gas, no coal needed – it's a fuel with zero air pollution or carbon dioxide emissions. High-tech and prestigious, it was seen as relatively safe. But then Fukushima came along. The disaster's global psychological impact exceeded Chernobyl's, and left a world that's now unsure if nuclear electricity is the answe
  • Core concerns The fire that followed the failure of emergency generators at the Daiichi nuclear complex raised the terrifying prospect of radiation leaking and spreading. The core of the Unit 1 reactor melted, and spent nuclear fuel, stored under pools of water, sprang to life as cooling pumps stopped. Fukushima's nuclear reactors had been built to withstand the worst, including earthquakes and tsunamis. Sensors successfully shut down the reactors, but when a wall of water 30 feet high crashed over the 20-foot protective concrete walls, electrical power, essential for cooling, was lost. The plume of radiation reached as far as Canada. Closer, it was far worse. Japan knows that swathes of its territory will be contaminated, perhaps uninhabitable, for the rest of the century. In July, for example, beef, vegetables, and ocean fish sold in supermarkets were found to have radioactive caesium in doses several times the safe level. [1]
  • The Japanese have been careful. In the country of the hibakusha (surviving victims of Hiroshima and Nagasaki), all reactors go through closer scrutiny than anywhere else. But this clearly wasn't enough. Other highly developed countries — Canada, Russia, UK, and US — have also seen serious reactor accidents. What does this mean for a typical developing country? There, radiation dangers and reactor safety have yet to enter public debate. Regulatory mechanisms are strictly controlled by the authorities, citing national security reasons. And individuals or nongovernmental organisations are forbidden from monitoring radiation levels near any nuclear facility. Poor and powerless village communities in India and Pakistan, that have suffered health effects from uranium and thorium mining, have been forced to withdraw their court cases.

  • Is nuclear energy cost efficient? A 2009 Massachusetts Institute of Technology study, which strongly recommended enhancing the role of nuclear power to offset climate change [2], found that nuclear electricity costs more per kilowatt-hour (kWh): 8.4 cents versus 6.2/6.5 cents for coal/gas. It suggested that as fossil fuel depletes, the nuclear-fossil price ratio will turn around. But it hasn't yet. The World Bank has labelled nuclear plants "large white elephants". [3] Its Environmental Assessment Source Book says: "Nuclear plants are thus uneconomic because at present and projected costs they are unlikely to be the least-cost alternative.
  • The aftermath of a Fukushima-type incident might look very different in many developing countries. With volatile populations and little disaster management capability, the social response would probably be quite different. In Japan, tsunami survivors helped each other, relief teams operated unobstructed, and rescuers had full radiation protection gear. No panic, and no anti-government demonstrations followed the reactor explosions. Questions about cost
  • There is also evidence that the cost figures usually cited by suppliers are substantially underestimated and often fail to take adequately into account waste disposal, decommissioning, and other environmental costs." [4] According to the US Nuclear Regulatory Commission, the cost of permanently shutting down a reactor ranges from US$300 million to US$400 million. [5] This is a hefty fraction of the reactor's original cost (20–30 per cent). While countries like France or South Korea do find nuclear energy profitable, they may be exceptions to a general rule. Countries that lack engineering capacity to make their own reactors will pay more to import and operate the technology.
  • Poor track record, military ambitions The track record of nuclear power in developing countries scarcely inspires confidence. Take the case of Pakistan, which still experiences long, daily electricity blackouts. Forty years ago, the Pakistan Atomic Energy Commission had promised that the country's entire electricity demand would be met from nuclear reactors. Although the commission helped produce 100 nuclear bombs, and employs over 30,000 people, it has come nowhere close to meeting the electricity target. Two reactors combine to produce about 0.7 GW, which meets around 2 per cent of Pakistan's electricity consumption.
  • India's record is also less than stellar. In 1962, it announced that installed nuclear capacity would be 18–20 GW by 1987; but it could reach only 1.48 GW by that year. Today, only 2.7 per cent of India's electricity comes from nuclear fuels. In 1994, an accident during the construction of two reactors at the Kaiga Generating Station pushed up their cost to four times the initial estimate. Cost overruns and delays are frequent, not just in India. And some developing countries' interest in nuclear technology for energy could mask another purpose. India and Pakistan built their weapon-making capacity around their civilian nuclear infrastructure. They were not the first, and will not be the last.
  • Warning bells ring loud and clear when big oil-producing countries start looking to build nuclear plants. Iran, with the second largest petroleum reserves in the world, now stands at the threshold of making a bomb using low enriched uranium fuel prepared for its reactors. Saudi Arabia, a rival which will seek its bomb if Iran makes one, has plans to spend over US$300 billion to build 16 nuclear reactors over the next 20 years. Climate change gives urgency to finding non-fossil fuel energy alternatives. But making a convincing case for nuclear power is getting harder. Neither cheap nor safe, it faces an uphill battle. Unless there is a radical technical breakthrough — such as a workable reactor fuelled by nuclear fusion rather than nuclear fission — its prospects for growth look bleak. Pervez Hoodbhoy received his PhD in nuclear physics from the Massachusetts Institute of Technology, USA. He teaches at the School of Science and Engineering at LUMS (Lahore) and at Quaid-e-Azam University, Islamabad, Pakistan.

Georgia residents may pay for Jaczko's antinuclear behavior [07Jul11] - 0 views

  • Georgia Power company stock
  • On a professional level, there is a lot riding on the success of the project to add two new Westinghouse AP1000 reactors to the Vogtle site in eastern Georgia along the Savannah River. It is one of only two remaining projects that is actually moving forward out of the finalists for the first round of loan guarantees initially authorized by the Energy Policy Act of 2005. It is the only project to have actually been awarded a conditional loan guarantee and the one that is most at risk of having a significant schedule interruption if the Nuclear Regulatory Commission dallies even longer in its review process for the completed design certification license application
  • This morning, the Wall Street Journal published Rebecca Smith’s article titled Georgia Eyes Cost Buffer for Nuclear Plant that described how the public utility commission is considering changing the cost recovery rules because they are being pressured by people who think that the project is in danger of a cost and schedule overrun. The company leaders testified that they would have chosen a natural gas project as being “more cost effective” (for the company) if they had known that there was a possibility of the rules of the game being changed six years after the project decision was made
  • ...7 more annotations...
  • I have been involved in the financial analysis of enough large projects to know that there are two sure ways to add cost to any project. The first method is to add delay
  • The second method is to add lawyers to the mix; they are professionally motivated to argue and delay. After all, they bill by the minute.
  • Here is the response that I posted in the comment section of Ms. Smith’s Wall Street Journal article.The sad part of the story was the apparent lack of understanding by the project detractors of the impact of their actions on the cost of the project. The length of time spent building the plant will have a very real impact on the cost of the project due to the fact that more time means more salaries, more interest on borrowed money, and a greater chance of increased prices for materials and equipment purchased and installed at a later time than planned.
  • Maintaining projected costs and schedules is highly dependent on the actions of regulators and intervenors who continue to slow down progress with legalistic arguments that have nothing to do with safety. The issues that the regulators raised are related to a difference of technical opinion on whether or not is reasonable to neglect the impact of solar heating and cooling while modeling the behavior of the containment building after an accident that releases 600 F water and steam into the building.
  • Westinghouse went back and recalculated the impact of the minor term in the equation – the final result was that under absolutely worst case conditions, the final pressure inside the containment went up by about 0.3 psi and was still well below the building’s allowed maximum pressure.
  • The current Chairman of the NRC is a professional political staffer whose complete professional experience following college was working for two avowed antinuclear politicians. He has cost taxpayers in 31 states billions already with his decision to refuse to finish the Yucca Mountain license review; now he is aiming to cost Georgia ratepayers and GA Power investors (remember, utility investors are often widows and orphans) hundreds of millions to billions more. He took the unprecedented step of issuing a press release calling Westinghouse’s application into question over such a technical dispute regarding the significance of terms in a mathematical model.
  • Americans need to know just how job unfriendly the NRC Chairman is.Full disclosure – I work for a company that is designing nuclear reactors that will soon need to be licensed by the Nuclear Regulatory Commission. I fear for my long term employment and that of hundreds of my colleagues and neighbors.

Florida approves 2012 FPL, Progress nuclear charges [25Oct11] - 0 views

  • FP&L to recover $196 million in 2012 * Progress Energy Florida request cut to $85.9 millionHOUSTON Oct 24 (Reuters) - Florida electric regulators on Monday approved requests from the state's two largest utilities to charge customers more than $280 million next year for work to develop four proposed nuclear reactors and to expand output at two existing plants.Florida is one of a handful of U.S. states in which laws were passed in the mid 2000s to revive the stagnant nuclear industry by offering utilities incentives to reduce the risk of building costly new reactors which take years to site, license and construct.The laws typically allow utilities to charge customers for certain project-related costs during the development and construction years in order to reduce long-term project financing costs.
  • The Florida Public Service Commission approved NextEra Energy's Florida Power & Light's full request to recover slightly more than $196 million from customers next year.Commissioners also agreed to allow Progress Energy's Florida utility to recover nearly $86 million next year for costs associated with a plan to build two new 2,200-MW reactors in Levy County, Florida.FP&L's amount includes costs related to the proposed 2,200-megawatt Turkey Point Units 6 and 7 and costs to add 450 MW of capacity at existing reactors at FP&L's Turkey Point and St. Lucie nuclear stations.That's up from only about $31 million approved for recovery in 2011 after a protracted dispute between the commission and the state's largest utility which has more than 4 million customers.
  • An FP&L spokesman said 90 percent of the funds requested for 2012 will pay for work to increase output at FP&L's existing reactors. About 29 MW is already in service with work to add the remaining 400 MW set for completion in 2013.Commercial operation of the new Turkey Point reactors, expected to cost between $12 billion and $18 billion, has been delayed about four years until 2022 and 2023 after FP&L said growth in power consumption slowed in the state during the economic recession.Progress Energy Florida initially sought $140.9 million, but the commission reduced that amount by more than $50 million under a 2009 plan deferring some early Levy costs due to the state's worsening economy.The proposed Levy County reactors, expected to cost about $20 billion, were originally set to begin operating in the 2016-17 time frame, but Progress delayed the timeline until at least 2020."We're pleased the commission confirmed our plan to make state-of-the-art nuclear power available to our customers in the state of Florida," Progress spokeswoman Suzanne Grant said.

  • Progress Energy's 1.7 million Florida customers will pay about $2.93 per month for the first 1,000 kilowatt-hours of electricity for early Levy costs, down from more than $5 a month this year.FPL customers will pay about $2.20 per month for the first 1,000 kwh used.The Florida Legislature passed a law in 2006 to encourage development of new nuclear plants and the PSC adopted a rule to evaluate project-related costs each year. The nuclear-related charges were added to customer bills beginning in 2009.

The Death of Nuclear Power: The Five Global Energy Moves to Make Now [07Jun11] - 0 views

  • out
  • Nuclear power was gaining a lot of momentum prior to the terrible disaster at Japan's Fukushima powerplant in March.
  • But since then, atomic energy has come under increased scrutiny and once again drawn the ire of environmentalists who were just warming up to its carbon-free emissions.
  • ...16 more annotations...
  • The German government's decision to close all of its existing nuclear reactors by 2022 shows that this shift in sentiment is gaining traction. And it increases the likelihood that the nuclear-powerplant building boom that had seemed at hand will be set back. Without a doubt, this new reality will lead to global energy shortages and much-higher energy costs.But for us as investors, the real issue is this: Which sectors will step up to alleviate the shortfall resulting from the inevitable disappearance of nuclear power?
  • As the recent development in Germany so clearly illustrates, one key difficulty about major energy decisions is that far too many are political in nature.
  • Too often, rational scientific analysis and cost-benefit analyses are ignored as hard-line environmentalists push their own agendas. Many of the environmentalists' objections are valid - at least as far as they go. But more and more, those objections seem to include every source of energy that actually works.
  • Windmills are objectionable because they look ugly and kill birds. Geothermal energy is objectionable because it causes earthquakes. Even solar energy is objectionable because of the vast acreages of land required to house the solar panels
  • Replacing Nuclear Power Figuring out which energy sources will offset the decline in nuclear power output requires three calculations:
  • First, a calculation of the cost of an energy source - as it now exists - in its economically most practicable uses. However, much as we may like solar power, we are not about to get solar-powered automobiles; likewise, oil-fueled power stations are inefficient on many grounds.
  • Second, a calculation that demonstrates whether the cost of that energy source is likely to increase or decline. With oil and hydro-electric power, for instance, the cost is likely to increase: The richest oil wells have been tapped and the best rivers have been dammed. With solar, on the other hand, the cost could decline, given how quickly the technology is advancing.
  • And third, an estimate that includes our best guess as to whether hard-line environmentalists will win or lose in their attempt to prevent its use.
  • On nuclear energy, the environmentalists appear to have won - at least for the time being. Their victory probably extends to fusion power, if that ever becomes economical. Conversely, their battles against wind and solar power are futile, as there are no scary disaster scenarios involved.
  • I regard the German decision to abandon nuclear power as foolish, and it should make us very cautious when investing in large-scale German manufacturers, which may be made uncompetitive by excessive power costs. But as an investor, I think it opens up a number of profit opportunities.
  • Actions To Take: Environmental concerns have chased investment away from nuclear energy - at least for the time being. For that reason the nuclear build-out that was just starting to gain momentum now is likely to stumble. As investors, we must look for energy sources that will most likely replace lost nuclear power output. They include:
  • Shale Gas: Potential damage to the environment caused by "fracking," which is the process by which shale gas is extracted, has not impeded this industry's growth. Natural gas has grown increasingly popular, as it is relatively cheap and clean, and readily abundant in the United States. A recent study by the Massachusetts Institute of Technology (MIT) suggests that natural gas will provide 40% of U.S. energy needs in the future, up from 20% today. You might look at Chesapeake Energy Corp. (NYSE:CHK), the largest leaseholder in Pennsylvania's Marcellus Shale, which is trading at a reasonable 9.5 times projected 2012 earnings.
  • Shale gas. Tar sands. And solar energy. Let's look at each of the three - and identify the best ways to play them
  • Tar Sands: The Athabasca tar sands in Canada contain more oil than the Middle East. And at an oil price of $100 per barrel, it is highly profitable to extract. Of course, extraction makes a huge mess of the local environment, but environmentalists seem to have lost that battle - reasonably enough, in view of the "energy security" implications of dependence on the Middle East. A play I like here is Cenovus Energy Inc. (NYSE: CVE). It's a purer Athabasca play than Suncor Energy Inc. (NYSE: SU), but it's currently pricey at 16.5 times projected 2012 earnings. Suncor's cheaper at only 11 times projected 2012 earnings - so take your pick
  • Solar Energy: Of the many new energy sources that have received so much taxpayer money in the last five years, solar is the one with real potential. Unlike with wind farms, where there is almost no opportunity for massive technological improvement or cost reduction, there is great potential upside with solar power: The technology and economics of solar panels and their manufacture is improving steadily. Indeed, solar power seems likely to be competitive as a source of electricity without subsidy sometime around 2016-2020, if energy prices stay high.
  • There are a number of ways to play this. You can select a solar-panel manufacturer like the Chinese JA Solar Holdings Co. Ltd. (Nasdaq ADR: JASO), or a rectifier producer like Power-One Inc. (Nasdaq: PWER). JA Solar is trading at a startling forward Price/Earnings (P/E) ratio of less than 5.0, mostly likely because of the Chinese accounting scandals, whereas Power-One is also cheap at less than seven times forward earnings and is U.S.-domiciled. Again, take your pick, depending on which risks you are comfortable with.

The nuclear power plans that have survived Fukushima [28Sep11] - 0 views

  • SciDev.Net reporters from around the world tell us which countries are set on developing nuclear energy despite the Fukushima accident. The quest for energy independence, rising power needs and a desire for political weight all mean that few developing countries with nuclear ambitions have abandoned them in the light of the Fukushima accident. Jordan's planned nuclear plant is part of a strategy to deal with acute water and energy shortages.
  • The Jordan Atomic Energy Commission (JAEC) wants Jordan to get 60 per cent of its energy from nuclear by 2035. Currently, obtaining energy from neighbouring Arab countries costs Jordan about a fifth of its gross domestic product. The country is also one of the world's most water-poor nations. Jordan plans to desalinate sea water from the Gulf of Aqaba to the south, then pump it to population centres in Amman, Irbid, and Zarqa, using its nuclear-derived energy. After the Fukushima disaster, Jordan started re-evaluating safety procedures for its nuclear reactor, scheduled to begin construction in 2013. The country also considered more safety procedures for construction and in ongoing geological and environmental investigations.
  • The government would not reverse its decision to build nuclear reactors in Jordan because of the Fukushima disaster," says Abdel-Halim Wreikat, vice Chairman of the JAEC. "Our plant type is a third-generation pressurised water reactor, and it is safer than the Fukushima boiling water reactor." Wreikat argues that "the nuclear option for Jordan at the moment is better than renewable energy options such as solar and wind, as they are still of high cost." But some Jordanian researchers disagree. "The cost of electricity generated from solar plants comes down each year by about five per cent, while the cost of producing electricity from nuclear power is rising year after year," says Ahmed Al-Salaymeh, director of the Energy Centre at the University of Jordan. He called for more economic feasibility studies of the nuclear option.
  • ...20 more annotations...
  • And Ahmad Al-Malabeh, a professor in the Earth and Environmental Sciences department of Hashemite University, adds: "Jordan is rich not only in solar and wind resources, but also in oil shale rock, from which we can extract oil that can cover Jordan's energy needs in the coming years, starting between 2016 and 2017 ... this could give us more time to have more economically feasible renewable energy."
  • Finance, rather than Fukushima, may delay South Africa's nuclear plans, which were approved just five days after the Japanese disaster. South Africa remains resolute in its plans to build six new nuclear reactors by 2030. Katse Maphoto, the director of Nuclear Safety, Liabilities and Emergency Management at the Department of Energy, says that the government conducted a safety review of its two nuclear reactors in Cape Town, following the Fukushima event.
  • Vietnam's nuclear energy targets remain ambitious despite scientists' warning of a tsunami risk. Vietnam's plan to power 10 per cent of its electricity grid with nuclear energy within 20 years is the most ambitious nuclear energy plan in South-East Asia. The country's first nuclear plant, Ninh Thuan, is to be built with support from a state-owned Russian energy company and completed by 2020. Le Huy Minh, director of the Earthquake and Tsunami Warning Centre at Vietnam's Institute of Geophysics, has warned that Vietnam's coast would be affected by tsunamis in the adjacent South China Sea.
  • Larkin says nuclear energy is the only alternative to coal for generating adequate electricity. "What other alternative do we have? Renewables are barely going to do anything," he said. He argues that nuclear is capable of supplying 85 per cent of the base load, or constantly needed, power supply, while solar energy can only produce between 17 and 25 per cent. But, despite government confidence, Larkin says that a shortage of money may delay the country's nuclear plans.
  • The government has said yes but hasn't said how it will pay for it. This is going to end up delaying by 15 years any plans to build a nuclear station."
  • The Ninh Thuan nuclear plant would sit 80 to 100 kilometres from a fault line on the Vietnamese coast, potentially exposing it to tsunamis, according to state media. But Vuong Huu Tan, president of the state-owned Vietnam Atomic Energy Commission, told state media in March, however, that lessons from the Fukushima accident will help Vietnam develop safe technologies. And John Morris, an Australia-based energy consultant who has worked as a geologist in Vietnam, says the seismic risk for nuclear power plants in the country would not be "a major issue" as long as the plants were built properly. Japan's nuclear plants are "a lot more earthquake prone" than Vietnam's would be, he adds.
  • Undeterred by Fukushima, Nigeria is forging ahead with nuclear collaborations. There is no need to panic because of the Fukushima accident, says Shamsideen Elegba, chair of the Forum of Nuclear Regulatory Bodies in Africa. Nigeria has the necessary regulatory system to keep nuclear activities safe. "The Nigerian Nuclear Regulatory Authority [NNRA] has established itself as a credible organisation for regulatory oversight on all uses of ionising radiation, nuclear materials and radioactive sources," says Elegba who was, until recently, the NNRA's director general.
  • Vietnam is unlikely to experience much in the way of anti-nuclear protests, unlike neighbouring Indonesia and the Philippines, where civil society groups have had more influence, says Kevin Punzalan, an energy expert at De La Salle University in the Philippines. Warnings from the Vietnamese scientific community may force the country's ruling communist party to choose alternative locations for nuclear reactors, or to modify reactor designs, but probably will not cause extreme shifts in the one-party state's nuclear energy strategy, Punzalan tells SciDev.Net.
  • Will the Philippines' plans to rehabilitate a never-used nuclear power plant survive the Fukushima accident? The Philippines is under a 25-year moratorium on the use of nuclear energy which expires in 2022. The government says it remains open to harnessing nuclear energy as a long-term solution to growing electricity demand, and its Department of Science and Technology has been making public pronouncements in favour of pursuing nuclear energy since the Fukushima accident. Privately, however, DOST officials acknowledge that the accident has put back their job of winning the public over to nuclear by four or five years.
  • In the meantime, the government is trying to build capacity. The country lacks, for example, the technical expertise. Carmencita Bariso, assistant director of the Department of Energy's planning bureau, says that, despite the Fukushima accident, her organisation has continued with a study on the viability, safety and social acceptability of nuclear energy. Bariso says the study would include a proposal for "a way forward" for the Bataan Nuclear Power Plant, the first nuclear reactor in South East Asia at the time of its completion in 1985. The $2.3-billion Westinghouse light water reactor, about 60 miles north of the capital, Manila, was never used, though it has the potential to generate 621 megawatts of power. President Benigno Aquino III, whose mother, President Corazon Aquino, halted work on the facility in 1986 because of corruption and safety issues, has said it will never be used as a nuclear reactor but could be privatised and redeveloped as a conventional power plant.
  • But Mark Cojuangco, former lawmaker, authored a bill in 2008 seeking to start commercial nuclear operations at the Bataan reactor. His bill was not passed before Congress adjourned last year and he acknowledges that the Fukushima accident has made his struggle more difficult. "To go nuclear is still the right thing to do," he says. "But this requires a societal decision. We are going to spark public debates with a vengeance as soon as the reports from Fukushima are out." Amended bills seeking both to restart the reactor, and to close the issue by allowing either conversion or permanent closure, are pending in both the House and the Senate. Greenpeace, which campaigns against nuclear power, believes the Fukushima accident has dimmed the chances of commissioning the Bataan plant because of "increased awareness of what radioactivity can do to a place". Many parts of the country are prone to earthquakes and other natural disasters, which critics say makes it unsuitable both for the siting of nuclear power stations and the disposal of radioactive waste.
  • In Kenya, nuclear proponents argue for a geothermal – nuclear mix In the same month as the Fukushima accident, inspectors from the International Atomic Energy Agency approved Kenya's application for its first nuclear power station (31 March), a 35,000 megawatt facility to be built at a cost of Sh950 billion (US$9.8 billion) on a 200-acre plot on the Athi Plains, about 50km from Nairobi
  • The plant, with construction driven by Kenya's Nuclear Electricity Project Committee, should be commissioned in 2022. The government claims it could satisfy all of Kenya's energy needs until 2040. The demand for electricity is overwhelming in Kenya. Less than half of residents in the capital, Nairobi, have grid electricity, while the rural rate is two per cent. James Rege, Chairman of the Parliamentary Committee on Energy, Communication and Information, takes a broader view than the official government line, saying that geothermal energy, from the Rift Valley project is the most promising option. It has a high production cost but remains the country's "best hope". Nuclear should be included as "backup". "We are viewing nuclear energy as an alternative source of power. The cost of fossil fuel keeps escalating and ordinary Kenyans can't afford it," Rege tells SciDev.Net.
  • Hydropower is limited by rivers running dry, he says. And switching the country's arable land to biofuel production would threaten food supplies. David Otwoma, secretary to the Energy Ministry's Nuclear Electricity Development Project, agrees that Kenya will not be able to industrialise without diversifying its energy mix to include more geothermal, nuclear and coal. Otwoma believes the expense of generating nuclear energy could one day be met through shared regional projects but, until then, Kenya has to move forward on its own. According to Rege, much as the nuclear energy alternative is promising, it is extremely important to take into consideration the Fukushima accident. "Data is available and it must be one step at a time without rushing things," he says. Otwoma says the new nuclear Kenya can develop a good nuclear safety culture from the outset, "but to do this we need to be willing to learn all the lessons and embrace them, not forget them and assume that won't happen to us".
  • But the government adopted its Integrated Resource Plan (IRP) for 2010-2030 five days after the Fukushima accident. Elliot Mulane, communications manager for the South African Nuclear Energy Corporation, (NECSA) a public company established under the 1999 Nuclear Energy Act that promotes nuclear research, said the timing of the decision indicated "the confidence that the government has in nuclear technologies". And Dipuo Peters, energy minister, reiterated the commitment in her budget announcement earlier this year (26 May), saying: "We are still convinced that nuclear power is a necessary part of our strategy that seeks to reduce our greenhouse gas emissions through a diversified portfolio, comprising some fossil-based, renewable and energy efficiency technologies". James Larkin, director of the Radiation and Health Physics Unit at the University of the Witwatersrand, believes South Africa is likely to go for the relatively cheap, South Korean generation three reactor.
  • It is not only that we say so: an international audit came here in 2006 to assess our procedure and processes and confirmed the same. Elegba is firmly of the view that blame for the Fukushima accident should be allocated to nature rather than human error. "Japan is one of the leaders not only in that industry, but in terms of regulatory oversight. They have a very rigorous system of licensing. We have to make a distinction between a natural event, or series of natural events and engineering infrastructure, regulatory infrastructure, and safety oversight." Erepamo Osaisai, Director General of the Nigeria Atomic Energy Commission (NAEC), has said there is "no going back" on Nigeria's nuclear energy project after Fukushima.
  • Nigeria is likely to recruit the Russian State Corporation for Atomic Energy, ROSATOM, to build its first proposed nuclear plant. A delegation visited Nigeria (26- 28 July) and a bilateral document is to be finalised before December. Nikolay Spassy, director general of the corporation, said during the visit: "The peaceful use of nuclear power is the bedrock of development, and achieving [Nigeria's] goal of being one of the twenty most developed countries by the year 2020 would depend heavily on developing nuclear power plants." ROSATOM points out that the International Atomic Energy Agency monitors and regulates power plant construction in previously non-nuclear countries. But Nnimmo Bassey, executive director of the Environmental Rights Action/Friends of the Earth Nigeria (ERA/FoEN), said "We cannot see the logic behind the government's support for a technology that former promoters in Europe, and other technologically advanced nations, are now applying brakes to. "What Nigeria needs now is investment in safe alternatives that will not harm the environment and the people. We cannot accept the nuclear option."
  • Thirsty for electricity, and desirous of political clout, Egypt is determined that neither Fukushima ― nor revolution ― will derail its nuclear plans. Egypt was the first country in the Middle East and North Africa to own a nuclear programme, launching a research reactor in 1961. In 2007 Egypt 'unfroze' a nuclear programme that had stalled in the aftermath of the Chernobyl disaster. After the Egyptian uprising in early 2011, and the Fukushima accident, the government postponed an international tender for the construction of its first plant.
  • Yassin Ibrahim, chairman of the Nuclear Power Plants Authority, told SciDev.Net: "We put additional procedures in place to avoid any states of emergency but, because of the uprising, the tender will be postponed until we have political stability after the presidential and parliamentary election at the end of 2011". Ibrahim denies the nuclear programme could be cancelled, saying: "The design specifications for the Egyptian nuclear plant take into account resistance to earthquakes and tsunamis, including those greater in magnitude than any that have happened in the region for the last four thousand years. "The reactor type is of the third generation of pressurised water reactors, which have not resulted in any adverse effects to the environment since they began operation in the early sixties."
  • Ibrahim El-Osery, a consultant in nuclear affairs and energy at the country's Nuclear Power Plants Authority, points out that Egypt's limited resources of oil and natural gas will run out in 20 years. "Then we will have to import electricity, and we can't rely on renewable energy as it is still not economic yet — Egypt in 2010 produced only two per cent of its needs through it." But there are other motives for going nuclear, says Nadia Sharara, professor of mineralogy at Assiut University. "Owning nuclear plants is a political decision in the first place, especially in our region. And any state that has acquired nuclear technology has political weight in the international community," she says. "Egypt has the potential to own this power as Egypt's Nuclear Materials Authority estimates there are 15,000 tons of untapped uranium in Egypt." And she points out it is about staying ahead with technology too. "If Egypt freezes its programme now because of the Fukushima nuclear disaster it will fall behind in many science research fields for at least the next 50 years," she warned.

BP gets Gulf oil drilling permit amid 28,000 unmonitored abandoned wells [25Oct11] - 0 views

  • Since BP’s catastrophic Macondo Blowout in the Gulf of Mexico last year, the Obama Administration has granted nearly 300 new drilling permits [1] and shirked plans to plug 3,600 of more than 28,000 abandoned wells, which pose significant threats to the severely damaged sea. Among those granted new permits for drilling in the Gulf, on Friday Obama granted BP permission to explore for oil in the Gulf, allowing it to bid on new leases that will be sold at auction in December. Reports Dow Jones: “The upcoming lease sale, scheduled for Dec. 14 in New Orleans, involves leases in the western Gulf of Mexico. The leases cover about 21 million acres, in water depths of up to 11,000 feet. It will be the first lease auction since the Deepwater Horizon spill.” [2]
  • Massachusetts Rep. Ed Markey objected to BP’s participation in the upcoming lease sale, pointing out that: “Comprehensive safety legislation hasn’t passed Congress, and BP hasn’t paid the fines they owe for their spill, yet BP is being given back the keys to drill in the Gulf.” Environmental watchdog, Oceana, added its objection to the new permits, saying that none of the new rules implemented since April 2010 would have prevented the BP disaster. “Our analysis shows that while the new rules may increase safety to some degree, they likely would not have prevented the last major oil spill, and similarly do not adequately protect against future ones.” [3]
  • Detailing the failure of the Dept. of Interior’s safety management systems, Oceana summarizes: Regulation exemptions (“departures”) are often granted, including one that arguably led to the BP blowout; Economic incentives make violating rules lucrative because penalties are ridiculously small; Blowout preventers continue to have critical deficiencies; and Oversight and inspection levels are paltry relative to the scale of drilling operation. Nor have any drilling permits been denied [4] since the BP catastrophe on April 20, 2010, which still spews oil today [5].

  • 28,079 Abandoned Wells in Gulf of Mexico In an explosive report at Sky Truth, John Amos reveals from government data that “there are currently 24,486 known permanently abandoned wells in the Gulf of Mexico, and 3,593 ‘temporarily’ abandoned wells, as of October 2011.” [6] TA wells are those temporarily sealed so that future drilling can be re-started. Both TA wells and “permanently abandoned” (PA) wells endure no inspections.
  • Not only cement, but seals, valves and gaskets can deteriorate over time. A 2000 report by C-FER Technologies to the Dept. of Interior identified several  different points where well leaks can occur, as this image (p. 26) reveals.  To date, no regulations prescribe a maximum time wells may remain inactive before being permanently abandoned. [13] “The most common failure mechanisms (corrosion, deterioration, and malfunction) cause mainly small leaks [up to 49 barrels, or 2,058 gallons]. Corrosion is historically known to cause 85% to 90% of small leaks.” Depending on various factors, C-FER concludes that “Shut-In” wells reach an environmental risk threshhold in six months, TA wells in about 10-12 years, and PA wells in 25 years.  Some of these abandoned wells are 63 years old.
  • Leaking abandoned wells pose a significant environmental and economic threat. A three-month EcoHearth investigation revealed that a minimum of 2.5 million abandoned wells in the US and 20-30 million worldwide receive no follow up inspections to ensure they are not leaking. Worse: “There is no known technology for securely sealing these tens of millions of abandoned wells. Many—likely hundreds of thousands—are already hemorrhaging oil, brine and greenhouse gases into the environment. Habitats are being fundamentally altered. Aquifers are being destroyed. Some of these abandoned wells are explosive, capable of building-leveling, toxin-spreading detonations. And thanks to primitive capping technologies, virtually all are leaking now—or will be.” [11] Sealed with cement, adds EcoHearth, “Each abandoned well is an environmental disaster waiting to happen. The triggers include accidents, earthquakes, natural erosion, re-pressurization (either spontaneous or precipitated by fracking) and, simply, time.”
  • As far back as 1994, the Government Accountability Office warned that there was no effective strategy in place to inspect abandoned wells, nor were bonds sufficient to cover the cost of abandonment. Lease abandonment costs estimated at “$4.4 billion in current dollars … were covered by only $68 million in bonds.” [12] The GAO concluded that “leaks can occur… causing serious damage to the environment and marine life,” adding that “MMS has not encouraged the development of nonexplosive structure removal technologies that would eliminate or minimize environmental damage.”
  • Over a year ago, the Dept. of Interior promised to plug the “temporarily abandoned” (TA) wells, and dismantle another 650 production platforms no longer in use. [7] At an estimated decommissioning cost of $1-3 billion [8], none of this work has been started, though Feds have approved 912 permanent abandonment plans and 214 temporary abandonment plans submitted since its September 2010 rule. [9] Over 600 of those abandoned wells belong to BP, reported the Associated Press last year, adding that some of the permanently abandoned wells date back to the 1940s [10].  Amos advises that some of the “temporarily abandoned” wells date back to the 1950s. “Experts say abandoned wells can repressurize, much like a dormant volcano can awaken. And years of exposure to sea water and underground pressure can cause cementing and piping to corrode and weaken,” reports AP.
  • The AP noted that none of the 1994 GAO recommendations have been implemented. Abandoned wells remain uninspected and pose a threat which the government continues to ignore. Agency Reorganization The Minerals Management Service (MMS) was renamed the Bureau of Ocean Energy Management, Regulation and Enforcement (BOEMRE) last May after MMS drew heavy fire for malfeasance, including allowing exemptions to safety rules it granted to BP. An Office of Inspector General investigation revealed that MMS employees accepted gifts from the oil and gas industry, including sex, drugs and trips, and falsified inspection reports. [14] Not only was nothing was done with the 1994 GAO recommendations to protect the environment from abandoned wells, its 2003 reorganization recommendations [15] were likewise ignored.  In a June 2011 report on agency reorganization in the aftermath of the Gulf oil spill, the GAO reports that “as of December 2010,” the DOI “had not implemented many recommendations we made to address numerous weaknesses and challenges.” [16] Reorganization proceeded.  Effective October 1, 2011, the Dept. of the Interior split BOEMRE into three new federal agencies: the Office of Natural Resources Revenue to collect mineral leasing fees, the Bureau of Safety and Environmental Enforcement (BSEE) and the Bureau of Ocean Energy Management (BOEM) “to carry out the offshore energy management and safety and environmental oversight missions.” The DOI admits:
  • “The Deepwater Horizon blowout and resulting oil spill shed light on weaknesses in the federal offshore energy regulatory system, including the overly broad mandate and inherently conflicted missions of MMS which was charged with resource management, safety and environmental protection, and revenue collection.” [17] BOEM essentially manages the development of offshore drilling, while BSEE oversees environmental protection, with some eco-protection overlap between the two agencies. [18] Early this month, BSEE Director Michael R. Bromwich spoke at the Global Offshore Safety Summit Conference in Stavanger, Norway, sponsored by the International Regulators Forum. He announced a new position, Chief Environmental Officer of the BOEM:
  • This person will be empowered, at the national level, to make decisions and final recommendations when leasing and environmental program heads cannot reach agreement. This individual will also be a major participant in setting the scientific agenda for the United States’ oceans.” [19] Bromwich failed to mention anything about the abandoned wells under his purview. Out of sight, out of mind. Cost of the Macondo Blowout
  • On Monday, the GAO published its final report of a three-part series on the Gulf oil disaster. [20]  Focused on federal financial exposure to oil spill claims, the accountants nevertheless point out that, as of May 2011, BP paid $700 million toward those spill claims out of its $20 billion Trust established to cover that deadly accident. BP and Oxford Economics estimate the total cost for eco-cleanup and compensatory economic damages will run to the “tens of billions of dollars.” [21] On the taxpayer side, the GAO estimates the federal government’s costs will exceed the billion dollar incident cap set by the Oil Pollution Act of 1990 (as amended). As of May 2011, agency costs reached past $626 million. The Oil Spill Liability Trust Fund’s income is generated from an oil barrel tax that is set to expire in 2017, notes GAO.
  • With Monday’s District Court decision in Louisiana, BP also faces punitive damages on “thousands of thousands of thousands of claims.” U.S. District Judge Carl Barbier denied BP’s appeal that might have killed several hundred thousand claims, among them that clean up workers have still not been fully paid by BP. [22] Meanwhile, destroying the planet for profit continues unabated. It’s time to Occupy the Gulf of Mexico: No more oil drilling in our food source.

Energy CEOs Urge Court To End Nuclear Waste Fee [25Oct11] - 0 views

  • A Department of Energy fee that costs nuclear power utilities some $750 million a year should be suspended because a nuclear-waste program the fee is designed to pay for does not exist, opponents said in a new court filing.
  • The National Association of Regulatory Utility Commissioners and the Nuclear Energy Institute, a policy organization for the industry, urged a Washington DC appeals court to order the DOE to stop collecting the fee for the federally mandated Nuclear Waste Fund which grows by about $1 billion a year and is expected to total $28.3 billion by the end of fiscal 2012.
  • The fund was intended to pay for the development and maintenance of a planned repository for nuclear waste at Yucca Mountain in Nevada, a long-delayed program that was effectively killed when the Obama administration cut off funding and support for it.
  • ...4 more annotations...
  • The White House initiative prompted NARUC and NEI to sue in March this year, arguing that the fee, which has been in effect since 1983, should be suspended because there was no justification for it.
  • In the latest filing, NARUC and NEI accuse the DOE of ignoring the size of the fund, the costs of the program it is intended to pay for, and the revenues already collected to pay those costs.
  • In their latest legal brief, filed on Oct. 20, and released by NARUC on Monday, the petitioners substantiate their claims that the DOE's determination in December 2010 to leave the fee unchanged is not in compliance with the 1982 Nuclear Waste Policy Act, which requires the department to regularly assess whether the fees are too high, too low, or necessary at all.
  • "Rather than complying with the NWPA requirement to annually evaluate the costs of the nuclear waste disposal program and determine whether the fees that have been and are being collected from ratepayers and utilities offset those costs, DOE has concluded that it must continue collecting the same fee it has been collecting since 1983 because it cannot determine that too much or too little revenue is being collected," the brief said.

IAA says 'Yes We Can' to power plants in orbit [15Nov11] - 0 views

  • Scientists from around the world have completed a study that says harvesting the sun's energy in space can turn out to be a cost effective way of delivering the world’s needs for power in as little as 30 years. As important, the report says that orbiting power plants capable of collecting energy from the sun and beaming it to earth are technically feasible within a decade or so based on technologies now in the laboratory.
  • These are findings in a report from the International Academy of Astronautics, headquartered in Paris. What their time references refer to are that the very technology needed to satisfy global energy requirements may be available in only 10 to 20 years, and the project can show cost-effectiveness in about 30 years. The IAA's three-year, ten-nation study, as the first broadly based international assessment of collecting solar energy in space, is considered significant. The study was conducted from 2008 to 2010 and was under peer review. John Mankins, the former head of concepts at NASA, led the study. The concept centers on placing one, then several, then many, solar-powered satellites in orbit over the equator. Each would be several miles wide. The satellites would collect sunlight up to 24 hours a day
  • The power would be converted to electricity in space, then sent to where it was needed on earth by a microwave-transmitting antenna or by lasers, and then fed into a power grid. Who would bear the cost of such an effort? The report recommends that both governments and the private sector should fund the research needed to further determine viability. A pilot project to demonstrate the technology could proceed using low-cost expendable launch vehicles being developed for other space markets, said Mankins, according to Reuters. A moderate-scale demonstration would cost tens of billions of dollars less than previously projected as a result of not needing costly, reusable launch vehicles early on.

Japan's Nukes Following Earthquake - 1 views

  • TEPCO has just released "diaries" from early in the accident giving us a better view of the sequence of events from the operators point of view.
  • The bulk of the materials, distributed on discs with digital files, show reams of raw numerical data. They include photos of broadsheet computer printouts and other formatted charts with thousands of data points for measurements of reactor heat, pressure, water levels, fuel rod positions and the status of cooling pumps, among other functions. Tokyo Electric, or Tepco, also released a smaller batch of more recent documents highlighting its various efforts to restore electric power to each of the reactors, a task that was achieved on April 26. But a series of what Tepco terms reactor "diaries" from the first 48 hours after the quake include the most visually arresting materials. These feature snapshots of whiteboards on which plant employees—11 of whom remained in each of the plant's three control rooms—jotted down status updates on the progress of the reactor shutdowns and steadily increasing radiation levels around the facility.
  • Using red, black or blue ink markers, the plant operators appear to have scribbled down the notes quickly. Many are smudged or illegible.

  • Fukushima may have a group that could tackle the nuclear crisis looming over Japan.

More than 200 Japanese retirees are seeking to replace younger workers at Fukushima while the plant is being stabilized. http://www.digitaljournal.com/article/307378
  • So helpless were the plant's engineers that, as dusk fell after Japan's devastating March 11 quake and tsunami, they were forced to scavenge flashlights from nearby homes. They pulled batteries from cars not washed away by the tsunami in a desperate effort to revive reactor gauges that weren't working properly. The plant's complete power loss contributed to a failure of relief vents on a dangerously overheating reactor, forcing workers to open valves by hand.And in a significant miscalculation: At first, engineers weren't aware that the plant's emergency batteries were barely working, the investigation found—giving them a false impression that they had more time to make repairs. As a result, nuclear fuel began melting down hours earlier than previously assumed. This week Tokyo Electric Power Co., or Tepco, confirmed that one of the plant's six reactors suffered a substantial meltdown early in Day 1. http://online.wsj.com/article/SB10001424052748704322804576302553455643510.html

  • In 1967, Tepco chopped 25 meters off the 35-meter natural seawall where the reactors were to be located, according to documents filed at the time with Japanese authorities. That little-noticed action was taken to make it easier to ferry equipment to the site and pump seawater to the reactors. It was also seen as an efficient way to build the complex atop the solid base of bedrock needed to better protect the plant from earthquakes.But the razing of the cliff also placed the reactors five meters below the level of 14- to 15-meter tsunami hitting the plant March 11, triggering a major nuclear disaster resulting in the meltdown of three reactor cores.http://online.wsj.com/article/SB10001424052702303982504576425312941820794.html
  • Toyota was a key executive who was involved in the Fukushima No. 1 plant construction.It is actually common practice to build primary nuclear plant facilities directly on bedrock because of the temblor factor.Toyota also cited two other reasons for Tepco clearing away the bluff — seawater pumps used to provide coolant water needed to be set up on the ground up to 10 meters from the sea, and extremely heavy equipment, including the 500-ton reator pressure vessels, were expected to be brought in by boat.In fact, Tepco decided to build the plant on low ground based on a cost-benefit calculation of the operating costs of the seawater pumps, according to two research papers separately written by senior Tepco engineers in the 1960s.
  • If the seawater pumps were placed on high ground, their operating costs would be accordingly higher."We decided to build the plant at ground level after comparing the ground construction costs and operating costs of the circulation water pumps," wrote Hiroshi Kaburaki, then deputy head of the Tepco's construction office at the Fukushima No. 1 plant, in the January 1969 edition of Hatsuden Suiryoku, a technical magazine on power plants.Still, Tepco believed ground level was "high enough to sufficiently secure safety against tsunami and typhoon waves," wrote Seiji Saeki, then civil engineering section head of Tepco's construction office, in his research paper published in October 1967.
  • Engineers at Tohoku Electric Power Co., on the other hand, had a different take on the tsunami threat when the Onagawa nuclear plant was built in Miyagi Prefecture in the 1980s.Like Fukushima, the plant was built along the Tohoku coast and was hit by tsunami as high as 13 meters on March 11.Before building the plant, Tohoku Electric, examining historic records of tsunami reported in the region, conducted computer simulations and concluded the local coast could face tsumani of up to 9.1 meters.Tohoku Electric had set the construction ground level at 14.8 meters above sea level — which barely spared the Onagawa plant from major damage from 13-meter-high tsunami that hit in March.

Cheap Solar Paint Takes a Giant Step Closer to Reality [10Apr10] - 0 views

  • For all the excitement over low cost solar power, much of it is still in the development stage backed by government resources and has yet to prove that it can compete on the market with cheap fossil fuels.   However some private investors are starting to bet on low cost solar in a big way.  Among them is tech specialist Len Batterson, whose startup  NextGen Solar is kicking into gear.NextGen Solar will use nanoscale solar “paint” technology developed by Argonne National Laboratory, with the goal of lowering production costs while increasing efficiency compared to thin-film photovoltaic materials.
  • Many Roads to Cost-Competitive SolarFrom turnkey solar kits to the use of low-cost solar materials, there are many different angles from which to push solar into the competitive energy market.  A solar paint that can be economically applied to different surfaces is one solution.  The National Renewable Energy Laboratory is already working on a silicon based solar ink, and The University of Texas is developing spray-on solar cells.  According to chicagobusiness.com writer Paul Merrion, Argonne’s solar technology can be applied to many types of building surfaces, including windows.  It goes on like paint, then dries to form microscopic interconnected solar cells.

Tepco cost cut goal said well short of target [03Oct11] - 0 views

  • Tokyo Electric Power Co. should cut costs by around twice as much as it is aiming for over the next 10 years if it expects to compensate victims of the nuclear crisis at its Fukushima No. 1 nuclear plant, a government panel said Monday.
  • In its report, the third-party panel also urged the utility to review its price-setting regime because its findings suggest that household power bills may be unnecessarily high due to cost overestimates on Tepco's side. One estimate in the report states that compensation payments could reach around ¥4.54 trillion by March 2013, including about ¥3.64 trillion for around a year starting from March 11, the day when the megaquake and tsunami crippled the plant.
  • The panel, tasked with scrutinizing Tepco's financial standing, submitted the report to Prime Minister Yoshihiko Noda. It is part of the process the utility must take to get state aid for the compensation payments. Calling the report a "starting point," Noda said the government would "strictly" check Tepco's rationalization efforts and look into the country's electricity pricing system. The outcome of the study, which started in June, showed that Tepco could cut ¥2.55 trillion in costs by fiscal 2020 by reducing personnel and other expenses. But Tepco's plan shows costs would only be cut by ¥1.19 trillion. The panel, meanwhile, urged Tepco's managers to take responsibility by jettisoning executives and other means if it intends to win financial aid from the state-backed Nuclear Damage Compensation Facilitation Corp.

  • This entity is to collect funds by issuing special government bonds and collecting contributions from other utilities that run nuclear power plants in Japan. The content of the panel's report will be reflected in Tepco's special operating plan, which is to be compiled with the entity this month. "Including the streamlining suggestion from the report in the special operating plan is like a minimum requirement for Tepco," said Kazuhiko Shimokobe, the lawyer who headed the panel. The report also points out that restarting the reactors at the sprawling Kashiwazaki-Kariwa power plant in Niigata Prefecture, the world's largest nuclear power plant, will be crucial to Tepco's medium term plan. Simulations in the report link the timing of the restarts and rate hike to Tepco's cash flow.
  • According to one simulation, if Tepco doesn't raise prices or restart the reactors in the next 10 years, it will face a cash shortage of about ¥8.6 trillion in fiscal 2020. Another says that if Tepco restarts the reactors by the end of fiscal 2014 and raises prices 10 percent, it will cut the shortage to ¥790 billion in fiscal 2020. First policy review The government was convening the first meeting of a panel of experts Monday to review the nation's energy policy in light of the Fukushima nuclear crisis. The panel, set up under the trade ministry's energy advisory panel, is tasked with reviewing Japan's basic energy plan, revised last year, which calls for building more than 14 new reactors to boost national reliance on nuclear energy to 53 percent by 2030 from about 30 percent. Its talks will likely differ from past ones as around 10 of its 25 members oppose nuclear power. A previous panel had few opponents because the ministry was promoting atomic power. The panel, headed by Nippon Steel Corp. Chairman Akio Mimura, plans to hold one or two meetings a month to compile a new energy plan by next summer.

Yucca Mountain cost estimate rises to $96 billion [06Aug08] - 0 views

  • The US Department of Energy (DoE) has issued a revised total cost estimate for the planned national used nuclear fuel and high-level radioactive waste (HLW) repository at Yucca Mountain, Nevada.    Yucca Mountain (Image: DOE) The latest estimate puts the cost of research, construction and operation of the geologic repository over a 150 year period - from when work started in 1983 through to the facility's expected closure and decommissioning in 2133 - at $96.2 billion (in 2007 dollars). This is a 67% increase on the previous published estimate in 2001 of $57.5 billion. Excluding inflation, the new estimate increased 38% to $79.3 billion.   The new estimated cost of $96.2 billion includes some $13.5 billion that has already spent on the project; $54.8 billion for the construction, operation and decommissioning of the repository; $19.5 billion for transportation of the used fuel; and, $8.4 billion for other program activities.

NextEra revises dates to boost Fla. nuclear output[25Oct11] - 0 views

  • Florida Power & Light, a unit of NextEra Energy Inc , plans to complete work to increase the output at its 839-megawatt St. Lucie 1 nuclear reactor during an extended refueling outage set to begin next month, according to a state regulatory filing.The work is part of FP&L's larger effort, known as a nuclear "uprate," to add 450 MW in capacity at four existing reactors at the Turkey Point and St. Lucie stations by 2013.FP&L, the state's largest electric utility, recently adjusted some of the outage dates to minimize an overlap between the planned nuclear outages and non-nuclear outages, utility officials said.Adding the 450 MW is now estimated to cost $2.48 billion, the company said, compared with FP&L's initial 2007 estimate of $1.5 billion for an increase of 400 MW.
  • The increased output will supply 209,000 customers, save $4.8 billion in fuel costs over the project's lifetime and cut carbon dioxide emissions in the state, said NextEra spokesman Michael Waldron.On Monday, the Florida Public Service Commission approved FP&L's request to recover about $196 million from customers next year for the uprate costs, as well as costs to develop two new reactors at Turkey Point expected to begin service in 2022-2023."The vast majority of our request -- about 90 percent -- is dedicated to the uprate project," Waldron said.In the filing, FP&L said it plans to shut St. Lucie 1 on Nov. 26 to perform work to increase its output by 122 MW. The outage is expected to last 110 days, or until mid-to-late February.
  • On Feb. 6, 2012, FP&L plans to shut the 693-MW Turkey Point 3 reactor for 120 days to boost that unit's output by 109 MW, the utility said in the filing.St. Lucie 2, also rated at 893 MW, is set to shut June 27, 2012, for 95 days for uprate work. The unit was shut for an extended period earlier this year for work that increased output by 29 MW due to a more efficient low-pressure rotor, the filing said.The extra 29 MW is helping to save $1 million per month in fuel costs, Waldron said.Next fall, the 693-MW Turkey Point 4 reactor is scheduled to shut Oct. 1 for 120 days for work to increase output by 109 MW, FP&L told state regulators.

  • To increase the output of reactors, operators install new pipes, valves and pumps, along with heat exchangers, new electric transformers, turbines and generators.The U.S. Nuclear Regulatory Commission is currently reviewing FP&L's uprate applications, which were filed in 2010 and early 2011.
