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.

The U.S. Department of Energy (DOE) on Thursday announced it would award $1 billion in Recovery Act funds to a revamped FutureGen proposal. The so-called “FutureGen 2.0” project contemplates repowering of an existing Ameren 200-MW coal unit in Meredosia, Ill., using oxyfuel technology—not construction of an integrated gasification combined-cycle facility at Mattoon, Ill., as originally envisioned. The new project still calls for use of the original Mattoon geologic storage site

to sequester carbon dioxide—however, the city of Mattoon has declined participation

in the project.

The U.S. Occupational Safety and Health Administration (OSHA) on Thursday cited three construction companies and 14 site contractors for 371 alleged workplace safety violations, and issued a total of $16.6 million in penalties. The fines follow an investigation into the causes of February’s deadly natural gas explosion at the Kleen Energy power plant construction site in Middletown, Conn. The explosion killed six workers and injured 50 others.

An Indiana state agency representing utility ratepayer interests in cases before regulatory commissions said it has “serious concerns” regarding cost overruns at Duke Energy’s 618-MW integrated gasification combined cycle (IGCC) facility at Edwardsport.

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.

By Kennedy Maize Washington, D.C., Aug. 9, 2010 –  Washington is abuzz with talk of a lame-duck session of Congress after the November mid-term elections. Many pundits seem to assume that the Democratic leadership will call the solons into session after the elections (with the Democrats having done very poorly, possibly losing their control of […]

Scuttling a high-profile “public nuisance” lawsuit, a federal appeals court has reversed a lower court ruling that required the Tennessee Valley Authority to accelerate plans to install pollution controls at four TVA coal-fired power plants to reduce the amount of pollution blowing into western North Carolina, saying the lower court decision could lead to other public nuisance suits that would wreak havoc on federal and state regulatory regimes for combating air pollution.

Saying they have “grave concerns” about the agency’s two-option proposal to regulate coal combustion ash, 31 members of the House Energy and Commerce Committee have urged the Environmental Protection Agency to continue to regulate coal ash as a non-hazardous waste, saying an EPA proposal to designate it as a “special” hazardous waste eligible for reuse would lead to costly and unnecessary management and disposal requirements.

An Environmental Protection Agency proposal to tighten sulfur dioxide and nitrogen oxides limits in 31 states and the District of Columbia to address transported air pollution fails to give utilities and state air regulators sufficient time to develop rules and install controls, according to American Electric Power Co. Officials from the EPA and New Jersey-based Public Service Enterprise Group said utilities already had begun making investments to cut emissions and they believed the agency’s compliance schedule could be met.
