The St. Charles Energy Center (SCEC) is a 725 megawatt natural gas-fueled combined-cycle power generation facility located in Waldorf, Maryland. The SCEC generates enough electricity to power more than 700,000 homes, helping Maryland to safely meet its demand for energy with reliable, cost-effective and environmentally-responsible low emissions generation. Using clean natural gas and a highly efficient design, the SCEC is one of the cleanest conventional facilities ever built in Maryland and the Washington, DC area. The facility is helping to reduce the dependency on older coal-burning power plants which currently supply a majority of the region’s power.
As part of CPV’s mission to conserve natural resources, the SCEC’s innovative design utilizes ”grey water” from the Mattawoman Water Treatment Facility to meet facility cooling needs. By using recycled wastewater that would otherwise be discharged into the Potomac River, the SCEC is minimizing its impact on valuable water resources and the environment while putting a waste product to productive use and creating an additional revenue stream for the region.
Type of Facility: Highly-efficient, combined-cycle (2-on-1) natural gas electric generating station
Location: In Charles County, MD, on land zoned for industrial use, previously permitted for a power plant, between high-voltage transmission lines and next to a landfill and an asphalt plant
Capacity: Generating capacity of 725 MW, enough to power 700,000 homes Facility On-Line: 2015/2016
Fuel: Natural Gas supplied by Dominion from either their Cove Point LNG terminal or their existing pipeline
Electrical Interconnection: The project site is adjacent to Pepco’s ROW containing four (Morgantown/Hawkins Gate to Talbert/Oakgrove) 230 kV circuits. CPV St. Charles requested interconnection to two of these four lines (23084 and 23086).
Cost: More than $500 million of private investment
