Seven miles downstream from the pumped storage project, Little Back Creek flows into Back Creek. If a storm blew down a tree, an uprooted rootball could displace enough earth to weaken the structure. When demand is low, water is pumped from the lower reservoir to the upper one. About 50 people work at the Bath County site, many in the power station, where they are required to wear hard hats and ear plugs. Probably no other storage solution has the track record of Pumped-Storage Hydropower. There, power is stored in the form of water to be used in the future. When one of the penstocks carved through Little Mountain was first filled with water, there was enough leakage and pressure changes through the limestone to buckle a steel liner in an empty, adjacent penstock. 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 VEPCO had alternatives. The water is regularly tested, according to Environmental Compliance Coordinator Susan Davis. The water flow is timed to provide electricity when demand peaks, typically in the summer when air conditioners kick on between lunch and early evening. After the Southwest Virginia delegation wrote and passed legislation during the 2017 General Assembly session to allow a similar pumped storage station in the coalfields, Dominion began efforts to consider a new site. This quickly showed that a significantly higher level of efficiency could be achieved by replacing the ventilation and cooling system as well as by redesigning the stator windings. The utility then sold Allegheny Energy a 40% share and completed construction. The conduits each lead to a 990 feet (300m) shaft which bifurcates into two penstocks (for a total of six) before reaching the turbines.
