State regulators said today that Progress Energy can build a natural gas-fired power plant as part of a plan that will allow Progress to shut down three older coal-burning power plants near Goldsboro.

The N.C. Utilities Commission approved the clean-burning gas plant in Wayne County under a state law enacted in July by the General Assembly and limited to this construction request by Raleigh-based Progress. The law required the commission to issue a ruling on the plant within 45 days, while the standard regulatory review would have taken at least six months for a power plant construction request.

The natural gas plant will have a capacity of 950 megawatts and is planned for operation in 2013. Progress will spend an estimated $900 million to build the plant, which still requires an air emissions permit from the N.C. Department of Environmental and Natural Resources.
