Xcel Energy claims that preliminary tests of a 1-MW battery-storage technology system shows the technology works. The company announced on August 3 that its wind-to-battery project showed it was possible to reduce the need to compensate for the variability of wind generation.

The U.S. Environmental Protection Agency filed suit against Michigan’s largest energy company, DTE Energy, for alleged violations of the federal Clean Air Act at that company’s  coal-fired Monroe Power Plant in Michigan.

California-based BrightSource Energy in the past week received two key approvals for its 392-MW Ivanpah concentrating solar power (CSP) plant in the Mojave Desert. The California Energy Commission’s (CEC’s) siting committee issued a proposed decision recommending approval, and on Friday, the U.S. Bureau of Land Management (BLM) issued its Final Environmental Impact Statement (FEIS) for the project.

A massive increase in organized “attacks” on the distribution power network in central England has resulted in more than a dozen downed wooden poles and thousands of customers without power in a week, E.ON UK said last week.

Constellation Energy on Monday said it had signed an asset purchase agreement to acquire Boston Generating’s 2,950-MW fleet, consisting of mainly natural gas–fired plants, for about $1.1 billion, or roughly $372/kW.

California, New Mexico, and three Canadian provinces—partners of the Western Climate Initiative (WCI)—last week released a detailed plan for a regional cap-and-trade program to curb greenhouse gases (GHG) starting in January 2012. If the plan reaches fruition, it would be three times larger than a program under way in 10 eastern states.

Hawaii’s Public Utilities Commission (PUC) last week denied a request by Hawaiian Electric Co. (HECO) to extend pilot testing for its advanced metering infrastructure (AMI) project to 5,000 more smart meter because of cost concerns. The move poses a major hurdle for the utility’s overall smart grid initiative.

Only 700 MW of wind power were added in the U.S. during the second quarter of 2010—a drop of 57% and 71% when compared to second quarter numbers from 2008 and 2009, respectively, the American Wind Energy Association (AWEA) reported last week.

New York state and Pennsylvania’s Department of Environmental Protection (PADEP) plan to sue Homer City Station, a 1,884-MW coal-fired power plant in Pennsylvania, for its alleged contributions of the region’s sulfur dioxide emissions.

The Department of Energy last week finalized a $117 million loan guarantee for a 30-MW Hawaiian wind power plant, and this week it said it would offer a $17.1 million loan guarantee to support construction of a 20-MW energy storage system using lithium-ion batteries.
