The lower reservoir dam on Back Creek is 135 feet (41m) high and 2,400 feet (730m) in length. During the summer, there may not be enough time to pump all the water back uphill before electricity demand rises again and the flow must be downhill to generate power. It is a configuration of two water reservoirs at different elevations that can generate power as water moves down from one to the other (discharge), passing through a turbine. On the banks of the lower reservoir, the Bath County pumped storage power station can be found nestling in the foothills of the Allegheny Mountains in the US state of Virginia. They were labelled as "exotic" and not considered to be viable alternatives, reflecting the technological capabilities and economics of the time.
