Some of the country's biggest energy companies are trying to figure out how to store the power. Bath County Pumped Storage Station Allegheny Power had proposed to build its own pumped storage project in West Virginia. If the electricity used to pump the water back up to the upper reservoir came from solar, wind, or nuclear power plants, then the pumped storage plant could be viewed as part of a power generation system that did not produce carbon dioxide (CO2) emissions. Small coal-fired power plants designed for quick start-up and gas-fired plants were realistic choices in 1971, as was a change in the rate structure to incentivize customers to reduce use of electricity at times of peak demand. The lower reservoir dam on Back Creek is 135 feet (41m) high and 2,400 feet (730m) in length. To find out more, please see our Privacy Policy. When the reservoirs are at full conservation storage levels, stockpiling 3,200 acrefeet, they release a minimum of 15 cubic feet per second (cfs). [10] 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. The facility incorporates an upper and lower reservoir impounded by zoned embankment dams, with a head differential of over 1,100 feet. | All engineering services in the following states are performed by Schnabels respective affiliated entity: Michigan: Schnabel Engineering of Michigan, Inc.; New York/Connecticut: Schnabel Engineering of New York; North Carolina: Schnabel Engineering South, P.C. A decision is expected in 2018. 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. Allegheny Energy was a separate utility than Appalachian Power, and at the time its Potomac Edison Company subsidiary sold electricity in Virginia. The vast majority of the complex, of almost twenty stories, is hidden beneath the surface of the water.

In 1971, VEPCO did not anticipate the fracking boom that would generate a surplus of gas three decades later, ultimately causing a dramatic reduction in the price of that fuel. Ludington uses a method called "pumped storage hydro-electricity," which essentially cycles Lake Michigan water through gravitational forces, storing electricity in the form of a makeshift battery. The project, located in Bath County, Virginia, celebrated its 25th anniversary on 18 December 2010. .

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 generators will spin the turbines backward, causing the turbines to pump water from a river or lower reservoir to an upper reservoir. A lot of the work is done underground, multiple stories below the surface, where the turbines generate electricity. We cover energy storage technologies a lot on this podcast. 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. Vital to grid reliability, today, the U.S. pumped storage hydropower fleet includes about 22 gigawatts of electricity-generating capacity and 550 gigawatt-hours of energy storage with facilities in every region of the country. Water released from the reservoir flows through a turbine, spinning it, which activates a generator that produces electricity.
