They provide a steady flow of water except in extreme droughts. Shifts in water levels within the upper and lower reservoirs are based on the demand for generating power, but the reservoirs could be used for flood control. The dam for the lower reservoir is to steep for mowing the grass, so Dominion Power rents a herd of 30 goats and an accompanying guard dog each summer.6, a dam 460 feet high blocks Little Back Creek and creates the upper reservoir You can use the Google Maps navigation app: Get directions to Bath County Pumped Storage Station.

Unlike a coal-fired or nuclear generating plant, there are no significant delays for "warming up" and no downtime for refueling.7, Peak power can be generated for only three hours. [10] An aerial view of the 265-acre upper reservoir and intake facility of the Bath County Pumped Storage Station, which produces hydroelectric power by gravity-feeding water to the powerhouse on the lower reservoir during daylight demand hours before that same water is returned to the upper reservoir during the night. The Bath County Pumped Storage Station was completed and started generating electricity in 1985. Bath County Pumped Storage Station, Virginia, USA, 3,003 MW capacity, completed 1985. What makes this different from other hydroelectric dams is that during times of low demand, power is taken from coal, nuclear, and other power plants and is used to pump water from the lower to the upper reservoir. VEPCO had alternatives. Back Creek and Little Back Creek, the water sources used to create the reservoirs, have a relatively small flow rate. 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.

Maximum static pressure from the top of the water delivery system to the turbines is 1,320 feet (400m). Once approved by Dominion and government agencies, Spencer Adkins said it would take 10 years to build and start a new site in Southwest Virginia. The biggest challenge in all of this was the transportation of the approximately 100-ton head covers which were divided into two parts. Coordinated expertise for your projects, from subsurface explorations and soil testing through engineering analysis, design, and construction support. Dan Genest of Dominion Energy, describes how the Bath County Pumped Storage Station produces electricity by gravity feeding water from the upper reservoir through the six turbines of the power house into storage in the lower reservoir before returning that same water to the upper reservoir during the night. Source: ESRI, ArcGIS Online. By continuing to use this website, you agree to their use. If the upper reservoir was fully drained over 11 hours, it could produce 24,000 megawatt-hours of electricity. The maximum power generation of 3,030MW is possible only when the reservoir is full. It opened in 1989 and consists of two ponds (27 and 45 acres). A location to build a new dam and reservoir would be difficult to find, but a small project might be feasible. We provide specialized expertise and design for geotechnical, dam, and tunnel engineering projects worldwide. The World's Biggest Battery (Classic) California is generating a ton of solar power--some days, more than people can use. Multidisciplinary experience across a variety of markets and geographies developing site-specific solutions and managing risk for project success. Voith dismantled the giant turbines piece by piece. penstocks cutting though Little Mountain include both horizontal and vertical sections Another seven miles later, Back Creek flows into the reservoir created by Gathright Dam, which is named Lake Moomaw. Cradled in Virginia's rugged Allegheny Mountains, the world's most powerful pumped storage generating station quietly balances the electricity needs of millions of homes and businesses across six states. One would have used Goose Creek and Bottom Creek near Roanoke, while the other used Little Back Creek and Back Creek in Bath County north of Covington. This significantly improves stream flow during periods of drought and enhances the environment for fish and other aquatic life.

Several U.S. locations use this method, such as the Bath County pumped storage station in Virginia, and the Raccoon Mountain pumped storage . It could ask for State Corporation Commission approval to build another coal-fired power plant or nuclear reactor, but the additional electricity would be unneeded for much of the day. 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. This page was last updated at 2023-03-03 06:36 UTC. 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).

For hard-working people in this tiny Bath County settlement, just miles away from an electricity generating plant that can move water at the same rate as it pours over Niagara Falls . It finally started building the Smith Mountain and Leesville dams in 1960, and completed them three years later. The advantage of the facility is that it serves as a battery which can be turned on quickly as demand shifts, 4,500 times per year. It has a structural volume of 4,000,000 cubic yards (3,100,000m3) and creates a reservoir with a surface area of 555 acres (225ha) and storage capacity of 27,927 acre-feet (34,447,000m3).

When storing power, the flow can be as much as 12.7million US gallons (48,000m3) per minute (800m3/s). 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. Deep within the powerhouse structure, Bill Mitchell, operations and maintenance manager of Dominion Energy's Bath County Pumped Storage Station, describes how the six water-spun turbines generate power. 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. 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. Visitors may also park at the closed entrance gate and walk into the park during the off-season.
