Pumped Storage

Pumped storage hydropower enables greater integration of other renewables (wind/solar) into the grid by utilizing excess generation, and being ready to produce power during low wind and solar generation periods. It also has the ability to quickly ramp electricity generation up in response to periods of peak demand.
