Possum Point Power Station
Powers 415,000 homes
- Net generating capacity is 1,661 megawatts (4 units).
- Units 3 & 4 are fired using natural gas (converted from coal in May 2003).
- Unit 5 is an oil-fired unit (#6 low sulfur oil).
- Unit 6 is fired by both natural gas and no. 2 oil.
- The station's two oldest units, Units 1 and 2, have been retired.
- The combined-cycle unit consists of two combustion turbines and a steam generator. Forced air, superheated by natural gas, turns a turbine to generate electricity. Exhaust from the combustion turbines is captured and used to produce steam to power another turbine.
- By recapturing the waste heat, combined-cycle units burn less fuel and produce fewer emissions than comparably sized conventional units.
- The station overlooks the Potomac River and the Quantico Creek.
- A new 14-mile pipeline was provided due to the natural gas requirements for the station.
- Approximately 85 percent of the pipeline is located within existing Dominion Energy overhead electric transmission rights-of-way or on other Dominion Energy property.
