Alstom introduces a new 3-MW wind turbine, one of the world’s most powerful for onshore installations; Solyndra reports its larges-ever rooftop installation of cylindrical photovoltaic (PV) systems — a 704-kW project in New Jersey; Plug Power reports that its GenDrive fuel cell units will power Walmart Canada’s fleet of electric lift trucks at a Alberta distribution center.
Customer-specific demand-response strategies become more sophisticated.
Demand-response technologies are quickly becoming more sophisticated, and markets are treating demand as a resource. But realizing the true potential of DR requires utilities to apply today’s technology solutions and program structures—and to base their strategies on actual customer behavior and preferences—rather than yesterday’s outdated assumptions about centralized load control.
Manufacturers scale up for utility applications.
Photovoltaics technology is emerging as a generation alternative—both for centralized and distributed facilities. Solar industry executives say their companies are overcoming obstacles to large-scale implementation. With advances in design and manufacturing, the future looks bright for utility-scale solar power.
Quantifying the economic benefits of generation alternatives.
Are renewables truly marking the start of a new economy, creating both economic growth and reliable jobs? Answering that question takes a complex analysis, but the numbers suggest green benefits might be smaller than expected.
Technologies are scaling up quickly to meet industry needs.
Like other California electric utilities, San Francisco-based Pacific Gas & Electric (PG&E) has been scrambling to meet the state’s renewable portfolio standard (RPS), which requires suppliers to obtain at least 20 percent of their power from renewable energy sources by 2010. Though the RPS includes a variety of technologies, renewables developers are choosing utility-scale solar power more than any other resource, says Hal La Flash, PG&E’s director of emerging clean technologies.
Rewards, challenges and options for rate-based investments.
Utilities traditionally have met renewable portfolio standards with power purchases from IPPs. But new approaches are allowing utilities to build their rate bases with investments in solar generation.
Capture and storage tech developments secure coal’s future.
Capture and sequestration will help ensure the future of coal-fired power plants. Demonstration projects are allowing utilities to kick the tires on the latest technologies, and to learn how CCS will affect operations and economics at state-of-the-art plants.
Subsidies might not be the best solution for interconnecting renewables.
Supporters of renewable energy are seeking to socialize the cost of a new interstate highway system for transporting green power. But utilities and transmission owners will build or finance new transmission systems to serve economic demands. Policy makers shouldn’t pre-ordain the direction of industry progress.
Renewable mandates will shift power to FERC but pose problems for RTOs.
A recent survey conducted by the U.S Office of Personnel Management and reported by the Washington Post on March 13 ranked the Federal Energy Regulatory Commission as eighth best of some 37 federal agencies in terms “talent,” and third in “leadership and knowledge.”
ITC and AEP jockey for the lead in building the grid of tomorrow.
