But hydroelectric power doesn't need a large dam. Capturing that much runoff could reduce the peak flow on Back Creek from 10,000 cubic feet per second (cfs) to 7,500 cfs. The generators will spin the turbines backward, causing the turbines to pump water from a river or lower reservoir to an upper reservoir. The transport of these components was completed during the winter months. The Bath County station can be online within six minutes to begin generating power, Mitchell said. The 500MW turbines can start exporting significant amounts of electricity into the grid within five-ten minutes. The Bath County Pumped Storage Station is the largest of its kind in the world, capable of producing enough electricity to power 750,000 homes, according to Jeremy Slayton, a spokesman for . However, the storage capacity behind such a dam was identified as too low, while costs to operate a small conventional hydropower facility were projected to be higher than at a large pumped storage project.1. Davis said the jobs created during construction of the Bath County site greatly boosted the local economy. Seven miles downstream from the pumped storage project, Little Back Creek flows into Back Creek. The Bath County pumped-storage facility has worked out so well for Dominion that the utility wants to build a smaller version in Southwest Virginia.

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 These projects include geophysical electrical resistivity imaging (ERI) surveys of both upper and lower dams; drilling and installation of vibrating wire piezometers to depths up to of 478 ft; preparing annual dam safety and surveillance monitoring plans; specification preparation for bathymetric and LiDAR surveys; updating supporting technical information documents; FERC Part 12 five-year inspection; potential failure mode analysis; and maintenance and replacement of instrumentation, including vibrating wire piezometers, weir instrumentation, weather stations, programming of Campbell Scientific dataloggers, and a unique automated monitoring system for pneumatic piezometers. Upper Reservoir consists of 265 surface acres and the water level fluctuates 105 feet during operation. Although this plant uses more power than it generates, it allows these other plants to operate at close to peak efficiency for an overall cost savings. If conservation storage drops to 50% or lower, the required minimum flows are reduced.11, two recreational ponds offer warmwater fishing, and 1.5 miles of Back Creek (between red asterisks) is designated as "Delayed Harvest Waters" for trout At times of low demand, such as the middle of the night, flow is reversed.

The lower reservoir dam on Back Creek is 135 feet (41m) high and 2,400 feet (730m) in length. . Neither of the two investor-owned utilities needed the full capacity to generate peak power from the facility, but sharing the power and sharing the costs made it feasible. Net generating capacity is 3,003-megawatts (6 units). The upper reservoir on Little Back Creek has a surface area of 265 acres (107ha) and storage capacity of 35,599 acre-feet (43,911,000m3). A major drought, restricting the ability to recharge the reservoirs with rainfall to offset evaporation and water released to maintain the fishery in Back Creek, could reduce that capacity. Water released from the reservoir flows through a turbine, spinning it, which activates a generator that produces electricity. The lower reservoir features a concrete spillway crest structure with two steel radial gates, a chute, and a stilling basin located on the right abutment of the lower dam. The Bath County Pumped Storage Station does not use fossil fuels to produce electricity, so it does not add greenhouse gases to the atmosphere.
