The Environmental Protection Agency (EPA) last week issued a long-awaited document that provides policy guidance to state agencies on how to start issuing permits to power plants and other stationary sources of greenhouse gases (GHG) when the rules take effect on Jan. 2. The document also provides technical information on how to implement the “Best Available Control Technology” (BACT) requirement for GHG sources applying to Prevention of Significant Deterioration (PSD) permits under the Clean Air Act—though it stops short of prescribing BACTs.

FirstEnergy Corp. today announced it would permanently shut down units 4 and 5 at its R.E. Burger Plant in Shadyside, Ohio, by Dec. 31, abandoning plans to repower the coal units with biomass. The Akron-based company cited a significant plunge in market prices of electricity, saying that they “no longer support a repowered Burger Plant.”

The UK’s Department of Energy and Climate Change (DECC) on Thursday approved a 900-MW combined cycle gas turbine (CCGT) power station in Spalding, Lincolnshire, in an effort to boost the nation’s energy security. The consent was given on the condition that the plant reserves enough space to allow for a future retrofit of carbon capture technology.

Exelon plans to invest nearly $5 billion in what it called “cost-effective, clean energy projects” starting this year.
