Departments of Energy and Interior award nearly $17M for advanced hydropower technologies

Green Car Congress

By allowing utility operators to pump water up to a dam or impoundment during periods of low electricity demand and release water during times of peak electricity demand, pumped storage hydropower improves the reliability of electric grids and helps increase the use of variable renewable energy resources such as wind and solar power.
