Pumped Storage

Definition

Pumped storage is a method of storing energy by using two water reservoirs at different elevations. During periods of low electricity demand, excess electricity is used to pump water from the lower reservoir to the upper reservoir. When there is high demand for electricity, the stored water is released back down to the lower reservoir, passing through turbines to generate electricity.

Analogy

Think of pumped storage like a giant rechargeable battery for electricity. Just like you charge your phone when it's not in use and use that stored power when you need it, pumped storage stores excess energy when it's not needed and releases it when there's a high demand.
