Definition: Pumped hydro storage uses water to store energy. A pumped hydro system's effective energy storage capacity is measured in GWh, or gigawatt hours. The volume of water required for a single GWh of energy storage is about a gigalitre. An off-river pumped hydro system can store as much as 20 GWh of energy.
