Chesterfield Power Station
Chesterfield County, VA
Powers 410,000 homes
- Net generating capacity is 1,640 megawatts.
- Primary fuel is coal and the average daily coal consumption is 8,400 tons.
- Commercial Operation began:
Unit 3 - 1952 | Unit 4 - 1960 | Unit 5 - 1964 | Unit 6 - 1969 | Unit 7 - 1990 | Unit 8 - 1992
- Dominion Energy's Chesterfield Power Station is the largest fossil-fueled power station in Virginia.
- Supplies about 12 percent of the electricity used by the 4 million people the utility serves.
- Chesterfield 7 and 8 are combined cycle units - burning clean natural gas and distillate oil. Instead of venting the hot exhaust gases to the atmosphere, they extract most of the heat to produce steam which turns another turbine - hence the name "combined cycle."
The combined cycle technology is tailor-made for tomorrow's power producers for several reasons:
- the units are small, efficient, relatively inexpensive and can be built in approximately one-third the time it takes to build a pulverized coal station,
- they can be installed at existing station sites with minimal environmental impacts, and
- it's a technology that can be adopted in stages - a feature that helps keep capacity additions in line with demand growth.
Because of its moderate costs, its flexibility, efficiency, and environmental advantages, the combined cycle technology offers tremendous potential for the future. It reinforces our strategy of building new generating facilities to meet capacity needs when building is the lowest-cost option available.
