New Energy Sources WhatsAppHow 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.
New Energy Sources WhatsAppExample - Hydro-power. The theoretically power available from a flow of 1 m 3 /s water with a fall of 100 m can be calculated as. P = (1000 kg/m 3) (1 m 3 /s) (9.81 m/s 2) (100 m) = 981 000 W = 981 kW Efficiency. Due to energy loss the practically available power will be less than the theoretically power.
