Solar power doubles pumped hydro output

Credit: heco.com

The falling price of solar power during the day in Germany means pumped hydro operators can operate at low prices twice a day now, not just at night when traditional power is cheaper. This potentially doubles output because now reservoirs can be filled twice a day.

With pumped hydro, water is pumped into reservoirs when power is cheap then released as needed to poer turbines.
