Pumped-storage power plants are reversible hydroelectric facilities where water is pumped uphill into a reservoir. The force of the water flowing back down the hill is then harnessed to produce electricity in the same way as conventional hydroelectric plants. Their ability to store electricity makes them an effective tool to overcome the …
