Dominion's hydroelectric power stations are a critical part
of our renewable energy portfolio. These stations harness energy from moving
water to generate electricity.
Each of the company's hydro stations are unique in their
design and operation. Electricity produced by the stations generally is used
to supplement the power generated at the company's other stations during periods
of high demand. Advanced technologies, top-quality training and a dedicated
workforce are the keys to the long-running success stories at these stations.
Gaston
Hydro Station, pictured here, is
located in Thelma, N.C. on the Roanoke River.
Gaston's four generators
collectively can produce up to 224 megawatts
to power 56,000 houses.
Roanoke
Rapids Power Station is located
near Roanoke Rapids, N.C. Its four generators
can produce up to 104 megawatts, which can
power 26,000 houses.
Cushaw Hydro Station is located in Big Island,
Va., and can power 500 houses with its 2 megawatts
of capacity. And the North Anna Hydro Facility is located in
Mineral, Va., and can power 225 houses with its
0.9 megawatts of capacity.
Bath
County Power Station, while not considered a renewable station in the Virginia
legislation, is a pumped storage facility in Virginia.
It uses electricity
during non-peak demand hours — when it would not be needed otherwise — to
pump water up to a holding facility.
During
peak demand hours, the water is released to
operate the turbine generators that provide
more than 2,100 megawatts of generating capacity, powering approximately 525,000
houses.
