Dominion Energy has referred to its Bath County facility as a "mountain of power" and "a quiet giant," and claims it is:3, There are nearly 300 pumped storage projects in the world, and 40 in the United States. Both reservoirs in Bath County were man-made. The project's licence was [] Maximum static pressure from the top of the water delivery system to the turbines is 1,320 feet (400m).[7][9]. While China is already home to more of the top 10 largest pumped storage power stations than any other country, the Fengning Pumped Storage Power Plant in China's Hebei Province will take the top position when completed in 2023, thanks to its 3.6 GW capacity. ABSTRACT:. In the 1970's, the limited availability and high price of natural gas made that option unattractive. Map. Dan Charles/NPR Dominion officials dont yet know if theyd add recreation facilities at a proposed Southwest Virginia site. 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. 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. Robert Steele, the project manager at Voith, recalls: "The head cover and the impellers were transported on a special 19 axle truck. The Okutataragi pumped storage station is located in Asago, in the Hygo Prefecture of Japan. A large outdoor powerhouse located at the lower reservoir contains six reversible pump-generating units, and a tunnel and penstock system conveys water between the two reservoirs. Hydroelectric power or hydropower is a clean, renewable energy source that generates about 10% of the nations energy. Pumped storage projects store and generate energy by moving water between two reservoirs at different elevations. The company also has contracted with Virginia Tech to study the feasibility of using an abandoned coal mine in Wise County to construct a pumped storage facility. Once described as the "world's largest battery," its maximum generation capacity is 3,003 megawatts and its total storage capacity is 24,000 megawatt-hours. Owned jointly by Dominion Energy (60%), Bath County Energy, LLC (approximately 24%) and Alleghany Power System (approximately 16%).

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. 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 maximum power generation of 3,030MW is possible only when the reservoir is full. The impellers were replaced. Baseload power plants provide the electricity to pump water back into the upper reservoir. 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. The water released from the lower reservoir into Back Creek is always cool, and offers a different fishery. The utility could have proposed to build a power plant fueled by natural gas, since such facilities could be turned on and off relatively quickly. License issued January 1977 and commercial operation began in December 1985. Source: ESRI, ArcGIS Online. A fishing habitat was created downstream of the facility.
