Pumped storage: powering a sustainable future
Pumped storage provides a ''load'' when the wind is blowing and the sun is shining, and it also provides a reliable and immediate source of dispatchable energy when the available renewable generation can''t meet demand. By pumping the water uphill when generation exceeds demand, the pumped storage scheme is essentially ''storing'' energy
