Marsh Run Generation Facility
Old Dominion Electric CooperativeFauquier County
Marsh Run Generation Facility is a 504-megawatt natural gas peaking plant in Remington, Fauquier County, Virginia, built in 2004 and solely owned by Old Dominion Electric Cooperative. ODEC began construction in 2003 using dual-fuel simple-cycle GE Frame 7FA combustion turbines, with Ragnar Benson as general contractor. The plant produces power quickly to meet peak demand and was planned to run about 57 days a year for ODEC’s distribution cooperatives.
