Innovative operation of pumped hydropower storage
In this pilot project, the foundations of the wind turbines are used as upper reservoirs of a PHS facility. They are connected to a pumped-storage power station in the valley that can provide up to 16 MW in power. The electrical storage capacity of the power plant is designed for a total of 70 MWh (Max Bögl, 2018).
News Release: NREL Analysis Reveals Benefits of Hydropower for Grid-Scale Energy Storage | News | NREL
Increasing the energy storage capacity can support a higher amount of renewable energy generation on the electric grid. Because renewable sources such as wind and solar do not generate electricity continuously, there is the risk of curtailment, where excess electricity is produced but cannot be used.
