Dominion Generation's Possum Point Power Station is a natural gas and oil plant located along the Potomac River in Dumfries, Virginia. The plant was commissioned in 1995 and has the total capacity of 1,661 MW. The plant has four generation units; two are natural gas fired, one is oil fired, and the last is a dual fired combined-cycle unit. Units 3 and 4 burned coal from 1955 through 2003, when they converted to burn natural gas. The station's two oldest units, Units 1 and 2, have been retired.
The station used to store byproducts from combustion of coal including fly ash and bottom ash in five surface impoundments. Ash from four of the impoundments has been removed and placed in Pond D, Possum Point’s only CCR disposal unit. No new CCR has been generated or placed in these impoundments since the conversion to gas‐ fired units in 2003. You can find the industry-reported data here.
