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

German Village; 100% Energy Independent & Renewable [24Aug12] - 0 views

  • The village of Feldheim 60km from Berlin has become an unusual tourist attraction. The village’s independent energy grid and 100% renewable energy sources has gained international attention. The village has its own energy grid and generates power from wind, biogas and solar. The model of Feldheim extinguishes the myth of needing nuclear or fossil fuel for baseload power and the assumption that big utility companies are required for electricity.
  • The transformation in Feldheim began in 1995 with a few wind turbines. Now the village has more wind turbines than homes. in 2008 the village added a biogas heat plant that runs off of corn waste and pig manure with a back up furnace that runs on lumber waste. In 2008 Feldheim decided they wanted their own energy grid. E,on refused to sell the existing grid to the city so they partnered with Energiequelle and built their own smart grid. Each villager paid in $3,972 for the grid installation but get a 31% savings on electricity and 10% savings on heat. It also created 30 permanent jobs for the town. Energiequelle is not building an electricity storage facility that will hold two days worth of electricity.
  • Feldheim did all of this while fighting the big utility companies and Germanies regulatory system that was not friendly to the drastic change Feldheim made.

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.
  • ...13 more annotations...
  • "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

NEI Nuclear Notes: Will Europe Struggle to Keep the Lights On? [28Oct11] - 0 views

  • A new study from consulting company Capgemini said that Europe may have trouble “keeping the lights on” this winter thanks to the nuclear phase-out in Germany.
  • Following its reactor shutdowns, Germany began to import electricity from its neighbors, including more than 2,000 MW per day from France. During the winter electricity peak, France mainly imports electricity from Germany and this will no longer be possible in coming years. This represents a real threat to some countries “keeping the lights on” for winter 2011/2012 and future winters.
  • The report sums it up well: without German nuclear generation, energy security is down, emissions are up. First, security. The Europeans better cozy up to the Russians because they will be more dependent on them than ever.

  • The Breakthrough Institute had this to say in its analysis of the German government plan to phase out nuclear.  
  • The plan indicates that--in the absence of nuclear power--Germany will continue to be heavily reliant on fossil-fuel generation for the bulk of its electricity supply.

Carnival of Nuclear Energy 60 [09Jul11] - 0 views

  • There are plans for eight more AP1000 reactors – four in Florida, two in North Carolina, and two in South Carolina. The next two AP1000s likely to be built are to be located near Miami at the Turkey Point power station operated by Florida Power & Light. The approval of the AP1000 design is turning into a high stakes outcome with much of the future of nuclear reactor construction in the U.S. over the next two decades riding on it. No other reactor vendor comes close.
  • UK continues on path to rebuilding a complete new sets of reactors. The Finnish government said that it has sent bid documents to Areva and Toshiba for responses to build a new nuclear power station. The new plant will need to generate up to 1,700 MW and be ready to produce power by 2020 at a cost of $6-9 billion
  • U.S. Nuclear Regulatory Commission has granted 20-year license renewals to the two reactors in Salem County, New Jersey. The two pressurized water reactors have been operating since 1977 and 1981 and generate just over 1,100 MW each.

Some countries make progress on nuclear energy despite Fukushima fears [25Sep11] - 0 views

  • Germany’s decision to close its reactors rejected as unrealistic
  • Since the March 11 earthquake and tsunami hit the six TEPCO reactors at Fukushima Japan, anti-nuclear groups have been on a roll.  Germany’s panic attack which will result in closing 17 reactors accounting for a quarter of its electricity is widely touted as a bellwether example for other countries.   The goal of post-industrial visionaries is to get the mainstream media and the public to accept a scenario of the inevitable end to the use of nuclear energy in as many places as possible. But is this trend really taking place?  Recent developments indicate it is not.  Here are some examples.
  • China to lift ban on new projects By early 2012 China will resume approving the start of new nuclear energy projects following completion of a national nuclear safety plan.  According to wire services, the China Securities Journal is reporting that in August the government completed the inspection of its existing fleet of nuclear reactors which provide about 11 Gwe of power.  It said that plants under construction, including four from Westinghouse and two from Areva, were also part of the review.  In an unexpected move, the Journal said the government would offer greater transparency on nuclear safety issues by making the results of the safety reviews available for public inspection.

  • Czech utility CEZ plans Europe’s largest reactor complexes The Czech government is planning a significant expansion of nuclear energy now that Germany has moved to shutter its 17 reactors by 2020.  A national energy strategy would call for building two or more new reactors at Temelin and three more at Dukovany. The two sites house a total of six existing reactors and grid infrastructure. 
  • Czech Industry & Trade Minister Martin Kocourek (right) told the Bloomberg wire service  September 8 the country will not give in to anti-nuclear influences from Austria or Germany. “Czech doesn’t need ideology.  What it needs is a rational update of its energy strategy.  The current ideology-driven policies of some countries is one thing; our reality is another.” If state-owned Czech utility CEZ builds all five reactors, worth about $28 billion, it will export electricity to Germany and Poland.  CEZ is expected to release documents related to the bid process next month.  The bidders are Areva, Westinghouse, and Rosatom.  An award for the first two new reactors to be built at Temelin is expected in 2013.
  • On September 15 CEZ named Daniel Benes, 41, as its new CEO with a mandate to execute a national energy strategy that includes building new nuclear reactors.  On September 20 Benes told financial wire services it will be his top priority linked to the goal of energy security for the Czech Republic.
  • On September 23 Czech President Vaclav Klaus (left) spoke at the United Nations in support of nuclear energy.  According to English language Czech news media, Klaus said: . . . “We consider what happened in Fukushima did not by any means question the arguments for nuclear energy.  These arguments are strong, economically rational and convincing.” He called Germany’s decision to close its reactors an “irrational populist event.”  In a parallel statement trade minister Kocourek said that CEZ would not expand renewable energy sources beyond 13% because it is unrealistic to expect to run a modern country on them.  He added CEZ “has big doubts” about biomass.
  • South Korea to invest in Romanian nuclear plant A South Korean nuclear energy consortium may invest in a project to build a third and a fourth reactor at Cernovoda in southeast Romania. The consortium replaces an investor group which pulled out of the project earlier this year.  The project manager for the new reactors is EnergoNuclear.  Right now Romania’s state owned electric utility holds an 85% share in the project and Italy’s ENEL holds another 9%. If the deal goes through, the South Korean group could take up to a 45 % stake in the project which is estimated to cost $5.7 billion.  Romania has two CANDU reactors at the site near the country’s Black Sea coast.  South Korea has experience with the CANDU design so it is plausible it may reference it in a proposal to build the next two units. This would be a huge win for AECL which recently was split up with its reactor division sold off for peanuts to SNC Lavalin.  AECL has marketed itself in eastern Europe hoping for this kind of development.

It's 2050: Do you know where your nuclear waste is? [09Sep11] - 1 views

  • Though nuclear power produces electricity with little in the way of carbon dioxide emissions, it, like other energy sources, is not without its own set of waste products. And in the case of nuclear power, most of these wastes are radioactive.1 Some very low level nuclear wastes can be stored and then disposed of in landfill-type settings. Other nuclear waste must remain sequestered for a few hundred years in specially engineered subsurface facilities; this is the case with low level waste, which is composed of low concentrations of long-lived radionuclides and higher concentrations of short-lived ones. Intermediate and high-level waste both require disposal hundreds of meters under the Earth’s surface, where they must remain out of harm’s way for thousands to hundreds of thousands of years (IAEA, 2009). Intermediate level wastes are not heat-emitting, but contain high concentrations of long-lived radionuclides. High-level wastes, including spent nuclear fuel and wastes from the reprocessing of spent fuel, are both heat-emitting and highly radioactive.
  • When it comes to the severity of an accident at a nuclear facility, there may be little difference between those that occur at the front end of the nuclear power production and those at the back end: An accident involving spent nuclear fuel can pose a threat as disastrous as that posed by reactor core meltdowns. In particular, if spent fuel pools are damaged or are not actively cooled, a major crisis could be in sight, especially if the pools are packed with recently discharged spent fuel.
  • Elements of success
  • ...17 more annotations...
  • All countries with well-established nuclear programs have found themselves requiring spent fuel storage in addition to spent fuel pools at reactors. Some, like the US, use dry storage designs, such as individual casks or storage vaults that are located at reactor sites; other countries, Germany for one, use away-from-reactor facilities. Sweden has a large underground pool located at a centralized facility, CLAB, to which different reactors send their spent fuel a year after discharge, so spent fuel does not build up at reactor sites. Dry storage tends to be cheaper and can be more secure than wet storage because active circulation of water is not required. At the same time, because dry storage uses passive air cooling, not the active cooling that is available in a pool to keep the fuel cool, these systems can only accept spent fuel a number of years after discharge.6
  • The United States had been working toward developing a high-level waste repository at Yucca Mountain, Nevada; this fell through in 2010, when the Obama administration decided to reverse this decision, citing political “stalemate” and lack of public consensus about the site. Instead, the Obama administration instituted the Blue Ribbon Commission on America’s Nuclear Future to rethink the management of the back end of the nuclear fuel cycle.8 The US can flaunt one success, though. The Waste Isolation Pilot Project (WIPP), located near Carlsbad in southern New Mexico, is actually the only operating deep geologic repository for intermediate level nuclear waste, receiving waste since 1998. In the case of WIPP, it only accepts transuranic wastes from the nuclear weapons complex. The site is regulated solely by the Environmental Protection Agency, and the state of New Mexico has partial oversight of WIPP through its permitting authority established by the Resource Conservation and Recovery Act. The city of Carlsbad is supportive of the site and it appears to be tolerated by the rest of the state.9
  • France has had more success after failing in its first siting attempt in 1990, when a granite site that had been selected drew large protests and the government opted to rethink its approach to nuclear waste disposal entirely. In 2006, the government announced that it needed a geologic repository for high-level waste, identified at least one suitable area, and passed laws requiring a license application to be submitted by 2015 and the site to begin receiving high-level waste by 2025.
  • Canada recently rethought the siting process for nuclear waste disposal and began a consensus-based participatory process. The Canadian Nuclear Waste Management Organization was established in 2002, after previous attempts to site a repository failed. The siting process began with three years’ worth of conversations with the public on the best method to manage spent fuel. The organization is now beginning to solicit volunteer communities to consider a repository, though much of the process remains to be decided, including the amount and type of compensation given to the participating communities.
  • the most difficult part of the back end of the fuel cycle is siting the required facilities, especially those associated with spent fuel management and disposal. Siting is not solely a technical problem—it is as much a political and societal issue. And to be successful, it is important to get the technical and the societal and political aspects right.
  • After weathering the Fukushima accident, and given the current constraints on carbon dioxide emissions and potential for growth of nuclear power, redefinition of a successful nuclear power program is now required: It is no longer simply the safe production of electricity but also the safe, secure, and sustainable lifecycle of nuclear power, from the mining of uranium ores to the disposal of spent nuclear fuel. If this cannot be achieved and is not thought out from the beginning, then the public in many countries will reject nuclear as an energy choice.
  • Certain elements—including an institution to site, manage, and operate waste facilities—need to be in place to have a successful waste management program. In some countries, this agency is entirely a government entity, such as the Korea Radioactive Waste Management Organization. In other countries, the agency is a corporation established by the nuclear industry, such as SKB in Sweden or Posiva Oy in Finland. Another option would be a public– private agency, such as Spain’s National Company for Radioactive Waste or Switzerland’s National Cooperative for the Disposal of Radioactive Waste.
  • Funding is one of the most central needs for such an institution to carry out research and development programs; the money would cover siting costs, including compensation packages and resources for local communities to conduct their own analyses of spent fuel and waste transportation, storage, repository construction, operations, security and safeguards, and future liabilities. Funds can be collected in a number of ways, such as putting a levy on electricity charges (as is done in the US) or charging based on the activity or volume of waste (Hearsey et al., 1999). Funds must also be managed—either by a waste management organization or another industry or government agency—in a way that ensures steady and ready access to funds over time. This continued reliable access is necessary for planning into the future for repository operations.
  • the siting process must be established. This should include decisions on whether to allow a community to veto a site and how long that veto remains operational; the number of sites to be examined in depth prior to site selection and the number of sites that might be required; technical criteria to begin selecting potential sites; non-technical considerations, such as proximity to water resources, population centers, environmentally protected areas, and access to public transportation; the form and amount of compensation to be offered; how the public is invited to participate in the site selection process; and how government at the federal level will be involved.
  • The above are all considerations in the siting process, but the larger process—how to begin to select sites, whether to seek only volunteers, and so on—must also be determined ahead of time. A short list of technical criteria must be integrated into a process that establishes public consent to go forward, followed by many detailed studies of the site—first on the surface, then at depth. There are distinct advantages to characterizing more than one site in detail, as both Sweden and Finland have done. Multiple sites allow the “best” one to be selected, increasing public approval and comfort with the process.
  • he site needs to be evaluated against a set of standards established by a government agency in the country. This agency typically is the environmental agency or the nuclear regulatory agency. The type of standards will constrain the method by which a site will be evaluated with regard to its future performance. A number of countries use a combination of methods to evaluate their sites, some acknowledging that the ability to predict processes and events that will occur in a repository decrease rapidly with each year far into the future, so that beyond a few thousand years, little can be said with any accuracy. These countries use what is termed a “safety case,” which includes multiple lines of evidence to assure safe repository performance into the future.
  • Moving forward
  • France, Canada, and Germany also have experienced a number of iterations of repository siting, some with more success than others. In the 1970s, Germany selected the Gorleben site for its repository; however, in the late 1990s, with the election of a Red–Green coalition government (the Greens had long opposed Gorleben), a rethinking of repository siting was decreed, and the government established the AkEnd group to re-evaluate the siting process. Their report outlined a detailed siting process starting from scratch, but to date too much political disagreement exists to proceed further.
  • Notes
  • Nuclear wastes are classified in various ways, depending on the country or organization doing the classification. The International Atomic Energy Agency (IAEA) notes six general categories of waste produced by civil nuclear power reactors: exempt waste, very short-lived waste, and very low level waste can be stored and then disposed of in landfill-type settings; low level waste, intermediate level waste, and high-level waste require more complex facilities for disposal.
  • Sweden is currently the country closest to realizing a final solution for spent fuel, after having submitted a license application for construction of a geologic repository in March 2011. It plans to open a high-level waste repository sometime after 2025, as do Finland and France.
  • Some countries, such as Sweden, Finland, Canada, and, until recently, the US, plan to dispose of their spent fuel directly in a geologic repository. A few others, such as France, Japan, Russia, and the UK have an interim step. They reprocess their spent fuel, extract the small amount of plutonium produced during irradiation, and use it in new mixed oxide (MOX) fuel. Then they plan to dispose of the high-level wastes from reprocessing in a repository.

Sun and wind as alternative to nuclear energy : Voice of Russia [04Jul11] - 0 views

  • Scared by the nuclear disaster at the Japanese Fukushima-1 Nuclear power plant, Germany, Italy and Switzerland have decided to abandon nuclear energy towards alternative sources of energy. How safe are these alternatives?  Today ecologists and scientists are trying to answer this question.Nature protection activists call alternative sources of energy “green” sources. However after a more detailed study these sources can hardly be regarded as “environmentally friendly”. Silicon solar arrays Europeans want to see on the roofs of their houses turn to be unsafe right at the stage of their production. The production of one ton of photo elements leads to the emission up to 4 tons of silicon tetrachloride, a highly toxic substance, which combinations may cause different diseases. Besides poisonous gallium, lead and arsenic the photo elements also contain cadmium. If cadmium enters a human body it can cause tumors and affect the nervous system.
  • As for wind turbines, their noise is dangerous for health and it is impossible to recycle the worn blades. Though green energy sources are not completely safe it is the question of choosing the lesser of two evils, Igor Shkradyuk, the coordinator of the program on the greening of industrial activities at the Center of Wild Life Protection, says."Absolutely environmentally clean energy does not exist.  All its types have stronger of weaker impact on the environment. A solar battery requires a huge amount of unhealthy silicon. Engineers hope that silicon-free materials for solar batteries will be produced in 10-20 years. The solar battery, if you don’t break it, of course, poses no danger. As for wind turbines, the first one was put into operation in mid 1970-s in Germany. But the residents complained about its strong vibration and noise and a local court ruled to stop it. Since then many things have changed and modern powerful wind turbines are unheard already at a distance of 200 meters. But they are the main source of danger for migrating birds which are almost asleep as they fly to their wintering grounds and back."
  • Vladimir Chuprov, the head of the energy department of Russia’s Greenpeace agrees that all sources of energy cause environmental damage.  But the alternative sources have advantages anyway, he says."Of course, we are negative towards any pollution and here the problem of choice comes up. For example, silicon production requires chlorine which is hazardous. But now the gradual transition to chorine-free methods of silicon production has already begun.  Besides that we see the gradual transition to thin-film photoconverters in particular arsenic based converters. And after all, nobody says that solar batteries will be thrown to a dump site. It is necessary to ensure their proper utilization."

  • The nuclear energy industry also faces serious upgrading. Russia has the project of constructing a nuclear power plant certified by the EU. This project takes into account all the tragic lessons of Fukushima. In particular such a plant will be capable to withstand the crash of an aircraft.Another problem of choice is the price. The energy from solar batteries and wind turbines is 2-5 times more expensive than that from nuclear energy. And while Germany is rejecting the use nuclear energy, France is proposing it to export its electricity produced by the French nuclear plants and China is ready to employ German experts in nuclear energy.

Citizen group wants radiation tests done in Canada following Fukushima nuclear disaster... - 0 views

  • A Vancouver woman wants Canadian governments held more accountable for protecting public health in the wake of the Fukushima nuclear crisis. In an August 8 interview at the Georgia Straight office, Isabel Budke pointed out that citizens and nongovernmental organizations can exert a great deal more pressure on Health Canada and other regulators to improve monitoring, measuring, and reporting on radiation levels in water, soil, and food.
  • “I really think we need to have localized and regional testing because, from what I understand, the plumes that have drifted over the Pacific Ocean with this radiation are touching down on different areas in different ways, depending on where the jet stream is going and what weather conditions are,” Budke said. “We can’t rely on testing results from the United States or testing that has been done somewhere else in the country. I think we need to have our own testing in B.C.”
  • Budke, who has an SFU master’s degree in environmental and resource management, said that if governments won’t do this work, she wants the public to work collaboratively to have food, soil, and water tested. Her group has created a “Canadian Network for Radiation Awareness & Monitoring” website, which will post results from citizen-initiated laboratory tests.

  • Last week, the Straight reported that on March 20, a Health Canada monitoring station in Sidney, B.C., detected iodine-131 at more than 300 times the background level. Despite this, Health Canada spokesperson Stéphane Shank told the Straight on August 9 from Ottawa that air-monitoring stations have shown that radiation levels are “minute” and pose “no risk” to Canadians. “Levels that are being detected are within the natural background radiation fluctuations that we would see on a normal, average day,” he claimed.
  • Budke remains unconvinced. She lived in Germany after the 1986 Chernobyl nuclear-reactor meltdown, which spewed radiation across Europe. At that time, she recalled milk being thrown out “by the tonne” because it was so contaminated. She added that to this day, meat from wild boars in Germany is sometimes discarded because these animals eat mushrooms, in which radioactive cesium bioaccumulates.

The Intermittency of Fossil Fuels & Nuclear [19Aug11] - 0 views

  • You’ve likely heard this argument before: “The wind doesn’t always blow and the sun doesn’t always shine, so we can’t rely on renewable energy.” However, a series of recent events undermine the false dichotomy that renewable energies are unreliable and that coal, nuclear and natural gas are reliable.
  • There are too many reasons to list in a single blogpost why depending on fossil and nuclear energies is dangerous, but one emerging trend is that coal, natural gas and even nuclear energy are not as reliable as they are touted to be. Take for instance the nuclear disaster still unfolding in Japan. On March 11, that country experienced a massive earthquake and the resulting tsunami knocked out several nuclear reactors on the coast. Three days later, an operator of a nearby wind farm in Japan restarted its turbines - turbines that were intentionally turned off  immediately after the earthquake. Several countries, including France and Germany, are now considering complete phase-outs of nuclear energy in favor of offshore wind energy in the aftermath of the Japanese disaster. Even China has suspended its nuclear reactor plans while more offshore wind farms are being planned off that country’s coast.
  • In another example much closer to home, here in the Southeast, some of TVA’s nuclear fleet is operating at lower levels due to extreme temperatures. When the water temperatures in the Tennessee River reach more than 90 degrees, the TVA Browns Ferry nuclear reactors cannot discharge the already-heated power plant water into the river. If water temperatures become too high in a natural body of water, like a river, the ecosystem can be damaged and fish kills may occur. This problem isn’t limited to nuclear power plants either.
  • ...5 more annotations...
  • Texas has been experiencing a terrible heat wave this summer - along with much of the rest of the country. According to the Dallas Morning News, this heat wave has caused more than 20 power plants to shut down, including coal and natural gas plants. On the other hand, Texan wind farms have been providing a steady, significant supply of electricity during the heat wave, in part because wind farms require no water to generate electricity. The American Wind Energy Association (AWEA) noted on their blog: “Wind plants are keeping the lights on and the air conditioners running for hundreds of thousands of homes in Texas.”
  • This near-threat of a blackout is not a one-time or seasonal ordeal for Texans. Earlier this year, when winter storms were hammering the Lone Star State, rolling blackouts occurred due to faltering fossil fuel plants. In February, 50 power plants failed and wind energy helped pick up the slack.
  • Although far from the steady winds of the Great Plains, Cape Wind Associates noted that if their offshore wind farm was already operational, the turbines would have been able to harness the power of the heat wave oppressing the Northeast, mostly at full capacity. Cape Wind, vying to be the nation’s first offshore wind farm, has a meteorological tower stationed off Nantucket Sound in Massachusetts. If Cape Wind had been built, it could have been using these oppressive heat waves to operate New England’s cooling air conditioners. These three examples would suggest that the reliability of fossil fuels and nuclear reactors has been overstated, as has the variability of wind.
  • So just how much electricity can wind energy realistically supply as a portion of the nation’s energy? A very thorough report completed by the U.S. Department of Energy in 2008 (completed during President George W. Bush’s tenure) presents one scenario where wind energy could provide 20% of the U.S.’s electrical power by 2030. To achieve this level, the U.S. Department of Energy estimates energy costs would increase only 50 cents per month per household. A more recent study, the Eastern Wind Integration and Transmission Study (EWITS), shows that wind could supply 30% of the Eastern Interconnect’s service area (all of the Eastern U.S. from Nebraska eastward) with the proper transmission upgrades. As wind farms become more spread out across the country, and are better connected to each other via transmission lines, the variability of wind energy further decreases. If the wind isn’t blowing in Nebraska, it may be blowing in North Carolina, or off the coast of Georgia and the electricity generated in any state can then be transported across the continent. A plan has been hatched in the European Union to acquire 50% of those member states’ electricity from wind energy by 2050 - mostly from offshore wind farms, spread around the continent and heavily connected with transmission lines.
  • With a significant amount of wind energy providing electricity in the U.S., what would happen if the wind ever stops blowing? Nothing really - the lights will stay on, refrigerators will keep running and air conditions will keep working. As it so happens, wind energy has made the U.S. electrical supply more diversified and protects us against periodic shut downs from those pesky, sometimes-unreliable fossil fuel power plants and nuclear reactors.
  •  
    a series of recent events undermine the false dichotomy that renewable energies are unreliable and that coal, nuclear and natural gas are reliable.

National responses to Japanese nuclear disaster [25Aug11] - 0 views

  • In his May 12, 2011 report "Fukushima Fallout: Regulatory Loopholes at U.S. Nuclear Plants," U.S. Representative Ed Markey (D-MA) stated: "Following the accident at the Fukushima Daiichi nuclear power plant in Japan, many other countries have announced new safety measures with regards to nuclear reactors. China, Venezuela, Switzerland, Italy, Japan, and Taiwan have suspended new reactor development. Germany and Japan announced it would shut down older reactors pending safety review." The table also shows that the Phillipines and the U.K. have decided to reduce the role of nuclear power in their energy future. And in fact Germany, the fourth biggest national economy on the planet, has decided to completely phase out nuclear power by 2022. (see Table 1 on page 24).

What to hate about nuclear energy [14Sep11] - 0 views

shared by D'coda Dcoda on 14 Sep 11 - No Cached
  • Reconsidering my support for nuclear energy I have found that it is only based in a desire to use it as a tool in the rather important fight against global warming and global meltdown. That in turn makes it possible to say “I hate nuclear energy. I just hate global warming more. So I support using it exactly until that problem is solved.” I said as much in my post yesterday with the nice title “Shut down those filthy nuclear reactors”.
  • So, what is there to hate about nuclear energy? Imagine you are a supporter of nuclear energy that is pushed by a silly reason like anger over being insulted by some random stranger on the Internet to actively look for anything that might be a problem with your former position. That is exactly what I have done. As a result, I have found basically two problems with it. One, which is the more important point, is the fact that the pro-nuclear position has lost in Germany, the only country where I actually have a vote. There is no German party I could vote for that supports building new nuclear reactors.
  • The victory of German anti-nuclear forces was quite decisive. That means as far as Germany is concerned, nuclear is just not a realistic option any more. Pro-nuclear advocacy is a waste of time, and a fringe minority position. Japan, the other country I might have some influence, is not quite as hopeless. Still advocating for a large increase in nuclear energy there does not seem a promising strategy.
  • ...2 more annotations...
  • The other thing I hate about nuclear energy is that most of pro-nuclear advocates are against renewable energy. That is not compatible with my point of view, making this a very efficient wedge issue for the anti-nuclear forces to exploit. Since most of the pro-nuclear advocates insist on bashing renewable energy, that point puts me out of the pro-nuclear advocacy business. For example, I regard the “Atomic Insights” blog by Rod Adams as hostile territory right now, and I am done writing any comments there for the time being.
  • So where does that leave me? I don’t exactly know yet. There are a couple of things that are clear already, however. One is that if anybody asks me to choose between nuclear and renewable, I will always choose the latter. That makes any form of pro-nuclear advocacy based on bashing renewable energy quite unacceptable to me. The other is that I am not quite joining the anti-nuclear advocates yet. I still think nuclear is needed as the most effective tool in the box against global warming. But my enthusiasm for advocating for that particular solution went down a couple of notches, so I will probably just focus more on discussing renewable energy issues.

Nuclear Twilight in Europe [07Jul11] - 0 views

  • The triple whammy against nuclear power beginning with the 1979 partial meltdown at Three Mile Island, followed by 1986′s Chernobyl  disaster and now Fukushima, effectively present a “three strikes and you’re out” call against civilian nuclear energy power generation for the foreseeable future.That said, with the trillions of dollars already invested in 436 nuclear power plants (NNP) worldwide, according to the International Atomic energy Agency (IAEA),  the industry has begun to push back, and “ground zero” is emerging as Europe, not Japan, with the lawyers circling.
  • In the wake of Fukushima, German Chancellor Angela Merkel announced on 30 May that Germany, the world’s fourth-largest economy and Europe’s biggest, would shut down all of its 17 would abandon nuclear energy completely between 2015 and 2022, an extraordinary commitment, given that Germany’s 17 NPPS Germany produce about 28 percent of the country’s electricity.If Berlin’s announcement sent nuclear power proponents seating, worse was to follow, as Switzerland is examining a proposal to phase out the country’s five nuclear plants by 2034.Finally, if any doubts existed about Europe’s commitment of nuclear energy, on 12-13 June in a referendum in which 56 percent of Italian voters participated, an eye-watering 94 percent voted against nuclear power.  Following the 1987 Chernobyl disaster, Italy decided to shut down its four NPPs and the last operating plant closed in 1990. Three years ago Prime Minister Silvio Berlusconi reversed this decision but after Fukushima Berlusconi announced a one-year moratorium on his plans for new nuclear power plants, intending to restart Italy’s nuclear energy program in 2014. Berlusconi spent the days leading up to the polls challenging the nuclear power measure in court, declaring he wouldn’t vote and suggesting his fellow Italians stay at home too. They didn’t, and Berlusconi’s electoral defeat has ended nuclear possibilities for Italy for the foreseeable future. In 2010, 22.2 percent of Italy’s power came from renewable energy sources. 64.8 percent were from fossil fuels, and 13 percent were imported sources, including French nuclear power. The stinging defeat at the polls is a boon for Italy’s nascent renewable energy industry.
  • The German nuclear industry has begun to fight back, insisting that its shutdown would cause major damage to the country’s industrial base. Utilities E.ON AG and Vattenfall Europe AG have already announced that they will seek billions of euros in compensation, and RWE AG and EnBW Energie Baden-Wuerttemberg AG are expected to follow soon.
