During the past 2 years, more flexible sourcing strategies across the wind power supply chain have resulted in cost reductions, enabling greater geographic market access while reducing risk and ensuring profitability for wind turbine vendors and their partners in the component value chain. Overcapacity, however, persists in most, though not all areas of the supply chain, providing purchasers with more choice, flexibility, and cost control. According to a new report from Navigant Research, while demand in 2014 is projected to be less than 47,000 megawatts (MW), annual turbine manufacturing capacity, according to vendor estimates, is likely to exceed 71,000 megawatts MW. "Oversupply is allowing wind turbine manufacturers to more easily adjust what components they produce in-house, what is outsourced, and when a blend of both is advantageous for cost, technological, or geographic reasons," says Jesse Broehl, senior research analyst with Navigant Research. "Although many manufacturing facilities are running at less than full capacity, product innovation, lean manufacturing, and outsourcing are resulting in a highly competitive wind industry ready for the challenges of today's and tomorrow's wind markets." Blades are a particularly strong area of strategic product evolution and sourcing shifts, according to the report. Turbine manufacturers are making major, capital-intensive investment changes in how blades are designed, what materials are used, the manufacturing processes behind them, and what companies they source from.
In the Lloydminster area, a Calgary company is ready to carve out large underground salt caverns to store excess wind energy — the first use of the technology in Canada. Rocky Mountain Power president Jan van Egteren says the storage sites could be ready in five years. Salt caverns have been used to store natural gas for years, but only two other projects in North America are using them for compressed air that is turned into electricity. The caverns are carved out by pumping water deep down to dissolve the underground salt layer peculiar to the Lloydminster area. Excess wind electricity would be used to pump compressed air into caverns about the size of a 60-storey building. The salt walls allow very little to escape. Then, when the wind dies, the compressed air is released and used to turn a generator to make electricity. The cavern could store enough compressed air to provide electricity for five days to a city the size of Red Deer, says van Egteren. “It could really help stabilize the grid by taking off power when the wind is really blowing.”
UNITED STATES: The US House of Representatives has approved a one-year extension to the production tax credit (PTC). The extension will allow US projects that began construction activities in 2014 to apply for the credit. It gives producers of wind power a $0.023/kWh incentive. The Senate will now need to approve the bill before it becomes law. The Senate vote is expected to take place in the coming days as both Houses are expected to adjourn for the Christmas break next week. Many in the industry had called for a two-year extension to the credit, which now would expire at the end of 2014. The Senate Finance Committee approved a two-year extension to the PTC in April, as part of a package of tax measures. The American Wind Energy Association (AWEA) said the extension creates uncertainty in the US sector. AWEA also warned of a dramatic slowdown to the industry, similar to 2013 when the PTC previously expired, resulting in a 92% drop in installations.
Did you hear about the largest solar power plant in the world and how it is now producing electricity? Did it make the nightly broadcast news? Probably not, but Solyndra was all over the news media for a while. There’s a blatant lack of coverage for solar success stories, so it wouldn’t be surprising if most people aren’t hearing about them. California’s Topaz project is the largest solar power plant in the world with a 550 MW capacity, and it is now in full operation. It is located in San Luis Obispo County and has 9 million solar panels. Construction began just two years ago. The electricity produced by the plant will be purchased by Pacific Gas and Electric. The solar panels were manufactured by First Solar and the project was developed by First Solar. SEIA says about 200 homes in California are powered for each MW of solar power capacity. So, for a 550 MW solar plant, about 110,000 homes could be powered when the sun is shining. First Solar has said this figure could be 160,000 homes in the case of Topaz. The San Luis Obispo county population is about 276,000. It might turn out that the majority of this population could be powered by a single solar power plant.

Tilt angles may reflect factors other than generator performance. Some installation sites may not be conducive to tilted arrays or specific orientations
System optimization is more than just good-looking charts - in this case, we are able to increase system profit by $40k, an increase of over 70% versus the 15ş-tilt baseline design.
In the United States, more than half of the energy we burn each year gets lost as heat instead of being put to use with most of the energy going out the exhaust pipe of a car or out the smokestack of a power plant.
Acquisition activity in Q3 2014 was lower than most quarters in recent history. Activity was distributed relatively evenly across the solar markets in Europe, North America and Asia, with cross-continental deals accounting for the greatest number of transactions.
With GIS, companies can view, understand, question, interpret and visualize data in many ways that reveal relationships, patterns and trends in the form of maps, globes, reports and charts.
ITM Power, the energy storage and clean fuel company, is pleased to note that the world's largest carmaker, Toyota, announced that it will begin selling fuel-cell electric cars in Japan on 15 December, 2014, and in the US and Europe in mid-2015.
The roads constructed using this technology are more durable and economical than the conventional bitumen roads.
Germany’s biggest utility firm, E.ON, has announced plans to split in two and spin off most of its power generation, energy trading and upstream businesses, responding to a crisis that has crippled the European energy sector. E.ON said it wanted to focus on its renewable activities, regulated distribution networks and tailor-made energy efficiency services, citing “dramatically altered global energy markets, technical innovation, and more diverse customer expectations”. “E.ON’s existing broad business model can no longer properly address these new challenges,” the chief executive, Johannes Teyssen, said in a statement. Germany’s power sector has been in turmoil, hit by a prolonged period of weak demand, low wholesale prices and a surge in renewable energy sources which continue to replace gas-fired and coal-fired power plants. E.ON said it would prepare next year for the listing of the new company created by its breakup, with the spin-off taking place after its 2016 annual general meeting.
A British start-up has developed a way for parking lots and structures with roofs that can’t take much weight to harness the power of the sun. The Cambridge, England-based Solar Cloth Company is beginning to run trials of its solar cloth, which uses lightweight photovoltaic fabric that can be stretched across parking lots or on buildings that can’t hold heavy loads, such as sports stadiums with lightweight, retractable roofs. Perry Carroll, Solar Cloth Company’s founder, told BusinessGreen that the company is working to close deals to install solar cloth on 27,000 parking lots. “We have built a growing sales pipeline worth £4.2m [about $US6.57 million] for 2015, including park and ride projects, airport parking operators and retail park owners,” he said. According to Solar Cloth Company, there are about 320 square miles of roof space and 135 square miles of parking space in the UK that could be covered by solar cloth, and if all of these spaces were covered, the solar power produced would be enough to power the UK’s grid three times.
According to the latest "Energy Infrastructure Update" report from the Federal Energy Regulatory Commission's (FERC) Office of Energy Projects, wind power provided over two-thirds (68.41%) of new U.S. electrical generating capacity in October 2014. Specifically, five wind farms in Colorado, Kansas, Michigan, Nebraska, and Texas came on line last month, accounting for 574MW of new capacity. In addition, seven "units" of biomass (102MW) and five units of solar (31MW) came into service accounting for 12.16% and 3.69% of new capacity respectively. The balance came from three units of natural gas (132MW - 15.73%). Moreover, for the eighth time in the past ten months, renewable energy sources (i.e., biomass, geothermal, hydropower, solar, wind) accounted for the majority of new U.S. electrical generation brought into service. Natural gas took the lead in the other two months (April and August). Of the 9,903MW of new generating capacity from all sources installed since January 1, 2014, 34 units of wind accounted for 2,189MW (22.10%), followed by 208 units of solar - 1,801MW (18.19%), 45 units of biomass - 241MW (2.43%), 7 units of hydropower - 141MW (1.42%), and 5 units of geothermal - 32MW (0.32%). In total, renewables have provided 44.47% of new U.S. electrical generating capacity thus far in 2014.
