Pumped Storage Hydro

How Pumped Storage Hydro Works. Pumped storage hydro (PSH) involves two reservoirs at different elevations. During periods of low energy demand on the electricity network, surplus electricity is used to pump water to the higher reservoir. When electricity demand increases, the stored water is released, generating electricity.
