The Bath County Pumped Storage Station, tucked away off a winding road in the northwest corner of the county near the West Virginia line, is the most powerful pumped storage station in the world . Looking for fishing, non-power boating, picnicking, swimming, hiking or camping? Dominion Energy hydroelectric power stations are unique in design and operation. The power grid will send energy into the electric generators at the station. Bath County Pumped Storage Station, Virginia, USA, 3,003 MW capacity, completed 1985. The Bath County Pumped Storage Station is . Counting seepage from the dam of the upper reservoir, Little Back Creek should receive a minimum of 2cfs. And at 3,000 MW, it's the 10th largest power plant in the U.S. Hoover Dam, by comparison, produces only two-thirds the power of Bath County. In Tazewell County, Dominion would pump water from a nearby mine. The site consists of six turbines, each of which can run up to 11 hours, according to Bill Mitchell, operations and maintenance manager. These components had to be delivered by special transport from the Voith plant in York some 250 miles away. 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. Each penstock is 18 feet (5.5m) in diameter and between 9001,260 feet (270380m) in length. The cost of a kilowatt-hour used to pump water uphill before dawn, when baseload plants can produce more electricity than customers are buying, is low. Dominion Virginia Power opened the Bath County Power Station Recreational Ponds, near Back Creek, in 1989. The upper reservoir dam is 460 feet (140m) high, 2,200 feet (670m) long and has a structural volume of 18,000,000 cubic yards (14,000,000m3). The conduits each lead to a 990 feet (300m) shaft which bifurcates into two penstocks (for a total of six) before reaching the turbines. The project, located in Bath County, Virginia, is owned jointly by Dominion Energy (60%) and Allegheny Power System (40%). The transport of these components was completed during the winter months. The flow when pumping uphill is slightly lower, at 12.7 million gallons per minute. The vast majority of the complex, of almost twenty stories, is hidden beneath the surface of the water. the six turbines are located in the powerhouse where three penstocks reach the lower reservoir In times of drought[11] water quality can be maintained[12] by using nearby recreational reservoirs to supply extra water to the creeks. The Bath County Pumped Storage Station is a pumped storage hydroelectric power plant, which is described as the 'largest battery in the world', with a maximum generation capacity of 3,003 MW, an average of 2,772 MW, and a total storage capacity of 24,000 MWh. Maximum static pressure from the top of the water delivery system to the turbines is 1,320 feet (400m). The power grid will send energy into the electric generators at the station. In operation since 1985, the Bath County station is capable of powering about 750,000 homes. The conduits each lead to a 990 feet (300m) shaft which bifurcates into two penstocks (for a total of six) before reaching the turbines. Direct Testimony of Kerinia Cusick Table of Contents I. Viewed from the lake, only the power house can be seen. WARM SPRINGS, Va. The 3,000-megawatt pumped storage station in Bath County, Virginia, similar to one proposed for Southwest Virginia is the largest of its kind in the United States. 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. A view up the ladder access to one of six hydraulic rams that control the intake gates on the upper reservoir of the Bath County Pumped Storage Station. The station is located in the northern corner of Bath County, Virginia, on the southeast side of the Eastern Continental Divide, which . 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. Pumped storage plants such as Bath County Pumped Storage Station can even store power. An aerial view of the 555-acre lower reservoir and earthen dam of the Bath County Pumped Storage Station, which produces hydroelectric power by pumping water from the 265-acre upper reservoir. 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 This maintains the pumped storage power station as an efficient and reliable energy supplier. A conventional hydroelectric plant was also considered. Dominion and government agencies test the quality, she added. Capturing that much runoff could reduce the peak flow on Back Creek from 10,000 cubic feet per second (cfs) to 7,500 cfs. [10] In order to serve you better, please select your Dominion Energy location services. When storing power, the flow can be as much as 12.7million US gallons (48,000m3) per minute (800m3/s). While simple in concept, hydroelectric power is highly efficient and environmentally friendly. In 2017 the largest pumped storage in Europe was the Cortes-La Muela hydroelectric project in Spain, rated at 1,762MW. A location to build a new dam and reservoir would be difficult to find, but a small project might be feasible. The station occupies a relatively small amount of land, minimizing adverse effect on the environment. Back Creek and Little Back Creek, the water sources used to create the reservoirs, have a relatively small flow rate. When full, the upper reservoir can has the capacity to provide 24,000 megawatt-hours of electricity. Another seven miles later, Back Creek flows into the reservoir created by Gathright Dam, which is named Lake Moomaw. The Bath County Pumped Storage Station is a pumped storage hydroelectric power plant, which is described as the "largest battery in the world", with a maximum generation capacity of 3,003 MW, an average of 2,772 MW, and a total storage capacity of 24,000 MWh. All six units were declared commercial in December 1985, and the plant has operated continuously since that . Coordinated expertise for your projects, from subsurface explorations and soil testing through engineering analysis, design, and construction support. During operation, the water level fluctuates by over 105 feet (30m) in the upper reservoir and 60 feet (20m) feet in the lower reservoir. overall cycle efficiency. When demand is low, water is pumped from the lower reservoir to the upper one. The dam on Back Creek, creating the lower reservoir, is 135 feet high. On Tuesday, Virginia media representatives toured Dominion Energys pumped storage station as the company considers a site in Southwest Virginia. The state agency has classified Back Creek between the dam and Route 600 as "Delayed Harvest Waters," requiring anglers to release whatever trout they catch and allowing use of just artificial lures (no bait) between October 1-May 31.10. Little Mountain, through which the penstocks were excavated, is also limestone. Directions. By selecting to choose later, you are choosing not to view state specific content.

From the exterior, the building may seem unimpressive. At times of low demand, such as the middle of the night, flow is reversed. Bill Mitchell is operations and plant manager at the Bath County pumped hydro storage plant. Cited as one of the nation's most outstanding 1985 engineering achievements. Some of the country's biggest energy companies are trying to figure out how to store the power. Introduction 2 II. If neither the Wise County nor Tazewell County sites are feasible, Dominion will look at other locations in the coalfields. The 500MW turbines can start exporting significant amounts of electricity into the grid within five-ten minutes. this will be updated as news is available . 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 generators will spin the turbines backward, causing the turbines to pump water from a river or lower reservoir to an upper reservoir. The upper reservoir dam is 460 feet (140m) high, 2,200 feet (670m) long and has a structural volume of 18,000,000 cubic yards (14,000,000m3).
