SAN FRANCISCO - The California Public Utilities Commission on Thursday approved a plan to set a cap on greenhouse gas emissions produced by the state's power plants.
The plan, which will join California with similar environmental programs in the eastern United States, will affect the investor-owned utility subsidiaries of PG&E Corp, Edison International and Sempra Energy. It also will include electricity from retail energy service companies such as Constellation New Energy, a unit of Constellation Energy Group Inc, and the Strategic Energy unit of Great Plains Energy Inc, a CPUC spokeswoman said.
Power imported from other states and electricity produced within California will be treated equally under the program. Details on the program's costs and impact on utility rates and penalties for going over the cap have yet to be worked out.
The CPUC has not decided yet on a baseline emissions cap level, but California Republican Gov. Arnold Schwarzenegger has laid out some targets. They call for the state to cut emissions by 25 percent below 1990 levels by 2020 and by 80 percent below 1990 levels by 2050.
