Back Creek and Little Back Creek, the water sources used to create the reservoirs, have a relatively small flow rate. A fishing habitat was created downstream of the facility. In times of drought[11] water quality can be maintained[12] by using nearby recreational reservoirs to supply extra water to the creeks. Construction of the Bath County Pumped Storage Station started in 1977, but stopped three years later because the growth in peak demand for electricity had not grown as projected by VEPCO. at the Bath County Pumped Storage Station, Dominion Energy pumps water between two reservoirs to create a giant battery providing electricity at times of peak demand About Stantec Communities are fundamental. The most common type uses a dam on a river to store water in a reservoir. With a total capacity of more than 3030 megawatts, Bath County is once more the most powerful pumped storage power station in the world following the modernization. However, since water is pumped between the reservoirs equally, the only water taken from these creeks now that the reservoirs are full is to replace the water lost to evaporation. Allegheny Energy was a separate utility than Appalachian Power, and at the time its Potomac Edison Company subsidiary sold electricity in Virginia. While the facility in Bath County is the largest now, a 4,000MW project at Lake Revelstoke in British Columbia has been proposed. There are also hermal and gravity storage systems.). Water released from the reservoir flows through a turbine, spinning it, which activates a generator that produces electricity. Pumped storage plants such as Bath County Pumped Storage Station can even store power. Allegheny Power sold its 12,000 acres in Canaan Valley to the US Fish and Wildlife Service in 2002.2.

VEPCO dropped its plans for a pumped storage project involving Goose Creek and Bottom Creek 15 miles southwest of Roanoke, and built in Bath County instead The station occupies a relatively small amount of land, minimizing adverse effect on the environment. Even with the additional 3,500MW (megawatts) from those four reactors, VEPCO calculated that it would need additional capacity during peak demand periods (typically 11:00am-8:00pm), but would have surplus capacity during nighttime. To use the power, the water is released from the upper reservoir back down into the river or lower reservoir. Lower Reservoir consists of 555 surface acres and water level fluctuates 60 feet during operation. Find out more about Pumped Storage at Stantec.
