Free Flow Power is currently developing a pumped storage project near Akron, Ohio. Generally, a pumped storage project consists of two reservoirs, with one at higher elevation than the other. Electricity can be generated on demand by releasing water from the upper reservoir, passing it through turbines, and releasing it into the lower reservoir. Water from the lower reservoir can then be pumped back into the upper reservoir to continue the cycle. The South Run Project would employ an abandoned underground mine as a lower reservoir, and have an upper reservoir situated on the surface above the mine.  South Run Pumped Storage Project will have a nameplate capacity of 1,500 MW.
