Pumped hydroelectric storage. renewable energy
Pumped hydroelectric storage operates according to similar principles to gravity-based energy storage. It pumps water from a lower reservoir into a higher reservoir, and can then release this water and pass it downwards through turbines to generate power as and when required. Water is pumped to the higher reservoir at times when electricity demand and prices are low. It is released when electricity demand rises. Image: International Hydropower Association
