USA - CommScope to supply Groundsmart™ Copper Clad Steel grounding wire to B... - 0 views

  •  
    CommScope, Inc. will supply the Bishop Hill Wind Farm in Henry County, Illinois with its GroundSmart(TM) Copper Clad Steel solution, an alternative to solid and stranded copper that is increasingly in demand by utilities for its cost-efficiency and anti-theft characteristics. CommScope will provide 1.7 million feet of GroundSmart copper clad steel grounding wire to the project this year--the largest GroundSmart application to date. The Bishop Hills Wind Farm will include approximately 130 wind turbines. Developers of Bishop Hill said that they see GroundSmart as a simple solution to reducing projects costs without compromising the system's integrity. Copper clad steel is specifically designed to disperse fault currents and lightning strikes at a lower total cost of ownership compared to pure copper.

  • Myth No. 1: Copper is the only conductor material for use in wind turbines. Reality: Traditionally, cable and wire manufacturers have used copper as the conductor material of choice for cables used throughout wind turbines. However, with copper prices being extremely volatile due to varying degrees of demand, cable research and development engineers use alternative conductor materials or copper alloys that perform comparably to pure copper when they can to combat the effects of copper’s changing price in order to keep turbine costs under budget.

An Ill Wind Blows On China's Turbine Business - 0 views

  •  
    The SERC (State Electricity Regulatory Commission) has released stricter technical regulations, especially for LVRT (Low Voltage Ride Through) reformation. Additionally, 18 industry standards have been released in November 2011 by the National Bureau of Energy. There are two immediate effects of the regulatory changes. Adding a LVRT capability will increase the cost of the Chinese turbines. This, coupled with slower demand, will lead to a squeezing out of the marginal producers who won't be able to afford to fit new equipment. Thus, the domestic wind power manufacturing sector in China is poised for tough times, when consolidation may even change the positioning of the top five players.

Solar Power From Saharan Sun Could Provide Europe's Electricity, Says EU - CommonDreams... - 0 views

  •  
    Dwarfed by any of the north African nations, it represents an area slightly smaller than Wales but scientists claimed yesterday it could one day generate enough solar energy to supply all of Europe with clean electricity. Speaking at the Euroscience Open Forum in Barcelona, Arnulf Jaeger-Walden of the European commission's Institute for Energy, said it would require the capture of just 0.3% The scientists are calling for the creation of a series of huge solar farms - producing electricity either through photovoltaic cells, or by concentrating the sun's heat to boil water and drive turbines - as part of a plan to share Europe's renewable energy resources across the continent. A new supergrid, transmitting electricity along high voltage direct current cables would allow countries such as the UK and Denmark ultimately to export wind energy at times of surplus supply, as well as import from other green sources such as geothermal power in Iceland. Energy losses on DC lines are far lower than on the traditional AC ones, which make transmission of energy over long distances uneconomic. The grid proposal, which has won political support from both Nicholas Sarkozy and Gordon Brown, answers the perennial criticism that renewable power will never be economic because the weather is not sufficiently predictable. Its supporters argue that even if the wind is not blowing hard enough in the North Sea, it will be blowing somewhere else in Europe, or the sun will be shining on a solar farm somewhere.

Ocean Power: Europe's Next Green Thing - 0 views

  •  
    Ireland's OpenHydro and Germany's RWE are spending millions to try to turn the power of waves into electricity With oil prices hitting almost daily record highs and global warming climbing up the public agenda, the need for alternative energy sources has never been more urgent. But while wind and solar have dominated the recent rush to invest in renewables, market watchers reckon it could now be marine energy's turn to shine. Ocean power-using the energy from waves or tidal flows to produce electricity-is quickly coming of age as a viable green resource that could help meet ambitious global targets to reduce greenhouse gases and dependency on fossil fuels. European and North American power companies such as Canada's Emera (EMA.TO) and Germany's RWE (RWEG.DE) are spending millions to fund wind and tidal projects. This investment has led to a new generation of more efficient technologies, with dozens of prototypes expected to be ready for commercial deployment within the next five years. "There's huge interest in both wave and tidal technology," says Thomas Boeckmann, clean tech analyst at market research firm StrategyEye in London. "It's gaining a lot of attention from energy companies, which will be able to offer financial backing and technical expertise to these startups."

    Sierra Pacific Power and Nevada Power Company have announced that they are expanding their SolarGenerations renewable energy programs to include cash incentives for wind and hydroelectric power systems as well as solar photovoltaic (PV) systems. Both Nevada utilities are wholly-owned subsidiaries of Sierra Pacific Resources. "These projects deliver benefits on many levels: they reduce energy bills, provide learning opportunities, help the environment, and increase our energy independence by taking advantage of abundant natural energy sources right in our own backyard." -- John Hargrove, Program Manage, Sierra Pacific & Nevada Power The last session of the Nevada State Legislature made the SolarGenerations demonstration program permanent, doubling the total amount of installed photovoltaic energy eligible for rebates from 1,900 kilowatts (kW) to 3,760 kW, and adding the new WindGenerations and HydroGenerations programs. Together, these programs are called RenewableGenerations.

Questions follow announcement of green superhighway - 0 views

  •  
    Wisconsin regulatory officials, utility companies and environmentalists agree that more line capacity is needed to transport electricity generated by the growing number of wind farms. But they're not sure ITC's plan for giant-sized lines is the answer. Michael Vickerman, executive director of the Madison environmental group, Renew Wisconsin, said he has "reservations" about the need for 765-kilovolt lines. Smaller transmission upgrades can accommodate new wind generation, he said. Wisconsin Public Service Commission Chairman Eric Callisto also has questions. "I don't want to close any doors to what they have proposed but I have lots of grave concerns about the cost," he said. ITC is proposing "very large lines" that would require "very large right-of-ways," Callisto said. A right-of-way is the legal permission to use a property owner's land or the area above it.

    US speciality brass mill Ansonia Copper and Brass Inc. has announced that it will lay off 85 of the 102 employees at its Liberty Street, Ansonia, factory in Connecticut. The plant manufactures copper alloy rod and wires. Company President Raymond McGee said "it's a very, very difficult situation". He blamed the redundancies, on top of 76 employees laid off in April 2007, on the company's struggle with escalating costs. Since 2002 electricity costs have soared 239%, natural gas 200%, fuel oil 125%, and copper and nickel 500% apiece. Ansonia's other facility in Waterbury, CT, which manufacturers copper alloy tube is unaffected by the announcement.

    In the past few days world leading cablemaker Nexans has announced one acquisition, one new joint venture and one asset disposal. On the 30th May, Nexans acquired Intercond a leading Italian manufacturer of special cables for industrial equipment and subsea applications. The company had sales of €90m and employs 150. "This [€90m] acquisition fits totally in the Group's strategy by increasing the proportion of its business in high value-added special cables", said Gerard Hauser, Chairman and CEO of Nexans. On the 2nd June, Nexans released a press report confirming that it has formed a joint venture to create a wire and cable plant in Qatar, the country's first manufacturing facility. Qatar International Cable Company (QICC) is owned 29% by Nexans with the balance being owned by Special Projects Company and Al Neama Industrial Co. The new plant in the industrial city of Mesaleed, 40km from Doha, and will employ 210 people. By the end of 2009 it will begin manufacturing low and medium voltage cables for buildings and energy infrastructure as well as special cables for the oil and gas industry. This JV will generate sales of $150m per year by 2010 at current copper prices. Finally, Nexans confirmed that it has completed the pre-announced sale of its copper telecom cable plant at Santander in Spain to the British company B3 Cable Solutions for €17m. These three actions continue to refocus the group's strategy on priority market segments.

    Turkish copper semis producer Sarkuysan expects its output of copper products (wirerod, wire, tube and billet) to rise from 185,000 tonnes in 2007 to around 200,000 tonnes in 2008. According to the General Manager Hayrettin Cayci, "The market is forcing us to increase production as demand, particularly in Turkey, is very healthy", adding that demand came mainly from a Turkish property construction boom. "There's a big boom in demand for energy cables. Plus developed European countries have pulled away from cable production and they're mainly supplying from countries like Turkey". However, high copper prices have eroded profit margins so the company is focussing on more higher value products. He expected total Turkish copper demand (refined and scrap) to rise above 500,000 tonnes this year, from 450,000 tonnes now, and by 2010 he expected demand would reach 600,000 tonnes. Refined copper consumption is currently around 300,000 tonnes.

    The Exsym Corporation, the joint venture between SWCC Showa Holdings and Mitsubishi Cable Industries, has announced plans to expand its exports of ultra high voltage cables to the Middle East and South East Asia. In order to meet this increase in demand, a horizontal sheathing line has been transferred to the company's Aichi plant in Japan. This will bring the number of sheathing lines for ultra high voltage cables at the plant to three, once the transferred line begins commercial operation over the summer. Exsym also plans to renew one of the two conductor stranding lines at the Aichi plant with the new line expected to begin commercial operation in November 2008. With these new lines as well as an increased number of construction staff, copper cable capacity at the plant is expected to grow by around 200 tonnes per month to 1,200 tonnes per month. In the fiscal year 2007, Exsym posted revenue of ¥41 billion ($0.39 billion) with an operating profit of almost ¥2 billion ($0.02 billion). Exports of ultra high voltage cables to the Middle East and South East Asia accounted for around 40% of the total revenue. The company expects the increase in export capacity to increase revenue to ¥43 billion ($0.41 billion) per year by the end of the fiscal year 2010.

    Mitsubishi Shindoh is to invest Yen6-7 billion to expand production of copper strips at its Sambo plant in Osaka, Japan. This will increase capacity from 3,200 tonnes per month (tpm) to 4,200tpm by March 2010. In addition, the company will transfer 800tpm of copper strip production from its plant in Wakamatsu, Fukushima, Japan, bringing total production capacity to 5,000tpm. Mitsubishi Shindoh will also spend Yen6 billion to improve its copper alloy strip capabilities at its Wakamatsu plant. Productive capacity will remain at 6,500tpm, but with an increased ratio of high quality products. As a result, total company capacity will grow by 40% to 11,500tpm. Mitsubishi Shindoh is a copper and copper alloy fabricator within the Mitsubishi Materials Group. Japan mills have recently seen a strong growth in orders from the semiconductor, leadframe, connector and automotive industries, and clearly expect this to continue.

    Hindalco Industries and Sterlite Industries - the two privately owned Indian copper smelter/refinery/rod producers - are considering changing their domestic pricing mechanism for copper due to the dramatic rise in oil prices. At present, a uniform pricing system for customers all over the country is in place, however, the companies are mulling a change to ex-works pricing. This would mean that customers would be charged a different price depending on their delivery destination from the smelter. To balance the recent hike in fuel prices, they had recently started levying a Rs2/kg freight charge across the country irrespective of distance. Diesel is used in firing the furnaces while furnace oil is used in running them. The total fuel cost is estimated at 10-12% of the price of copper, with 1% of this being the transportation cost. The fuel price hike has not affected domestic copper demand as yet, but a prolonged period of this sentiment may hit many developing infrastructure projects badly.

    Jiangxi Copper said it expects Chinese refined copper consumption to grow at 8-10% this year driven by investment in the power industry. Power generation accounts for between 50-60% of all copper used in China. Damage to power generation capacity caused by this year's earthquake in Sichuan province will require a major rebuilding program which will also stimulate copper consumption. Chinese refined copper imports fell by 23% year on year between January and April, however, this decline was at least partly explained by a 23% expansion in Chinese refined copper production during the period. Wu Yuneng, General Manager of JCC Southern Copper said, "We need more concentrate and scrap rather than refined copper".

    Four major Japanese copper tube producers plan to reduce production by 4% year-on-year to 84,220 tonnes in total during the first half of the fiscal year 2008 (April 07-March 08). It is reported that demand for copper tubes has fallen because of the inactive construction industry as well as high copper prices. The construction industry saw a major slowdown last year after the introduction of new building regulations. All four producers expected this weak trend to continue. Sumitomo Light Metal is the only producer who plans to increase its output estimate, but only by 1% year-on-year. Kobelco & Materials Copper Tube says that it would decrease normal tube output for export to adjust the inventory level at its Malaysian operation. Furukawa Electric and Hitachi Cable said they would need to focus more on their commercial tube businesses. It is believed that the tube market has also been hit by substitution from aluminium.

    A subsidiary of Japanese company Sumitomo Electric Industry Group, Sumitomo Electric Wintec Inc, has recently developed a new type of winding wire. The HGZ is a scratch-resistant winding wire for varnish impregnation for compressor motor. The company has started selling this new type of winding wire. This new development improves the adhesive tendency of varnish which solves the problem of varnish impregnation in fixing coil from traditional scratch-resistant winding wire. It also improves the energy efficiency of motor as it forms coil with higher density. Sumitomo Electric Wintec specialises in copper-based magnet wire and it serves mainly the manufacturers of air conditioners, automobiles, refrigeration equipment and televisions.

    Luvata's ECO-Heatcraft division has launched a new technology for its air conditioning and refrigeration systems based upon using carbon dioxide as a refrigerant. The company believes that, as well as offering zero ozone depletion and less effect on global warming, the use of carbon dioxide can also allow more efficient operation of the system than traditional refrigerants. Luvata claims that, "The higher volumetric efficiency of carbon dioxide (known as R744) means that the cross sectional area of pipes used in heat transfer equipment can be reduced. As a result, equipment has the potential to be smaller, lighter, more efficient and better for the environment". The development of smaller diameter pipes with reduced wall thicknesses would tend to favour existing inner grooved copper tube based designs rather than emerging aluminium based technologies.

    Further evidence of the impact of the North American economic slowdown on copper demand has recently been published by the ABMS and government statistical bodies. North American copper wirerod production plummeted 9.6% year-on-year to 174,000 tonnes in April. Output had been on a downward trend but the magnitude of the deterioration in April has still come as something of a surprise. A year-on-year increase of 2.0% in North American output January had been followed a 1.0% fall in February and a 2.7% drop in March. In April Canadian output was flat year-on-year due to improving export sales to the US, while US production fell 9.8% year-on-year and Mexican shipments slumped by 17.5%. On a year-to-date basis North American wirerod production was 2.9% lower in the four months to April 2008. Weakening demand from the automotive industry, coupled with a resurgance in copper prices and the return of Russian wirerod imports has clearly led to a deteriorating market situation for domestic mills.

    Mueller Industries second quarter results highlight the tough times that the US brass mill industry is facing, but that companies can still operate profitably in a challenging market environment. The company's plumbing and refrigeration segment saw sales fall 11% to US$404m, while its operating profits dropped 32% to US$35m. The company blamed lower shipment volumes and lower spreads for the weaker performance. Sales at the company's OEM division, which includes its brass rod activities, rose 10% year-on-year to US$354m, while its operating profits rose 5% to US$19m. The improvement here is due to acquisition of Extruded Metals. Commenting on the results Harvey Karp, Chairman of Mueller Industries said "Mueller's earnings for the first half of 2008 were achieved despite the continuing decline in the housing industry, the sub-prime mortgage meltdown, the turbulence in the financial markets, rising metal costs, sky-high energy prices and a slowing national economy. Considering these adverse circumstances, we are pleased with the results."

Technology Review: Wind Power That Floats - 0 views

  •  
    Historically, wind technology has been seen on land and near offshore locations. Restrictions, such as prohibitively expensive offshore foundations to support wind turbines larger than 20 meters, may be viewed as stunting potential market growth. Now, new technology based on floating turbines may enable deeper offshore placement. The view mentioned with this news is that pushing turbines further out to sea will equalise the issue of aesthetics. However, the real issue here is can this technology deliver a useful and economic addition to the grid.

Electricity industry looks to a green electric future - 0 views

  • Carbon capture and storage remains a nascent technology: no one has yet proved that an integrated process can work on a commercial scale. But the US, Canada, Australia, the European Union and others have pledged billions of dollars to back demonstration projects. This suggests commercial deployment could be possible around 2020.Even so, any transition to carbon-free generation will take decades. Low-carbon technologies are generally more expensive than fossil-fuel plants: some, such as offshore wind, are a lot more expensive. And with wind, power generation will not be constantly available. Britain, which is backing Europe's fastest expansion of wind power, is building into its plans for 2030 a huge margin of spare generation capacity which can be used when there is no wind.
