Pumped hydroelectric energy storage, or pumped hydro, stores energy in the form of gravitational potential energy of water. When demand is low, surplus electricity from the grid is used to pump water up into an elevated reservoir.

What is a storage hydroelectric system?

Storage hydroelectric systems store water for later use, which makes them a versatile resource for the grid. For example, large hydroelectric dams can be sited on rivers with valleys, creating an artificial lake or reservoir. Turbines and generators in the powerhouse generate electricity when water flows from higher-to-lower elevation.

Can hydropower be used to store electricity?

Hydro can also be used to store electricity in systems called pumped storage hydropower.
