Handling stresses to protect the generator. The pumped storage power plants (PSPP) are one of the commercially proven methods available for grid-scale energy storage. Building additional PSPPs particularly in the areas with high installed capacities of wind parks and solar power plants will significantly improve the grid reliability.
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).
