Bill Mitchell, operations and maintenance manager of Dominion Energy's Bath County Pumped Storage Station, describes how the six water-spun turbines generate power deep inside the powerhouse. Two downstream lakes are available for visitors. 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. In times of drought[11] water quality can be maintained[12] by using nearby recreational reservoirs to supply extra water to the creeks. Bath County Pumped Storage Station is the world's most powerful pumped hydro facility, quietly balancing the electricity needs of millions of homes and businesses. The generators will spin the turbines backward, causing the turbines to pump water from a river or lower reservoir to an upper reservoir. There are two pull-offs along Rt. 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. Bath County Station is jointly owned by Dominion Generation (60%) and FirstEnergy (40%), and managed by Dominion. Robert Steele, the project manager at Voith, recalls: "The head cover and the impellers were transported on a special 19 axle truck.
