Possum Point
Possum Point is a 709 MW regulated electric utility generating station at 19000 Possum Point Road in Dumfries, Prince William County, Virginia, operated by Virginia Electric & Power Co (d/b/a Dominion Energy Virginia) within the PJM Interconnection. The facility comprises nine generators: six 16 MW petroleum-liquids combustion turbines (GT1–GT6) and a 613 MW natural-gas/distillate-fuel-oil combined-cycle block (G784) consisting of two 174 MW combustion turbines (6A, 6B) and one 265 MW steam turbine (6ST). The facility has undergone significant configuration changes, with coal units closing in 2003, converted units retiring in 2019, and an oil-fired unit ceasing operation in 2021. Dominion announced in January 2025 a modernization project to add approximately 44 MW of capacity through upgrades to the gas and steam turbines, driven by increasing Northern Virginia data-center power demand. Virginia DEQ regulates coal-ash disposal and environmental compliance through solid-waste permit SWP617 and VPDES permit VA0002071.
