Pumped storage hydropower (PSH) currently accounts for over 90% of storage capacity and stored energy in grid scale applications globally. The current storage volume of PSH stations is at least 9,000 GWh, whereas batteries amount to just 7-8 GWh.
As the most mature and cost-effective energy storage technology available today, pumped storage power stations utilize excess WPP to pump water from a lower reservoir (LR) to an upper reservoir (UR).
PSH acts similarly to a giant battery, because it can store power and then release it when needed. The Department of Energy''s "Pumped Storage Hydropower" video explains how pumped storage works. The first known use cases of PSH were found in Italy and Switzerland in the 1890s, and PSH was first used in the United States in 1930.
In operations, hydropower stations utilize their own reservoir storage to redistribute uneven inflows over periods of years, months, weeks, days or hours, thereby controlling when and how much electricity is generated. This ability enables them to quickly respond to the increasing demand for flexible power in electrical grids 2, 3.
Our home solar PV systems and energy storage products are engineered for reliability, safety, and efficient deployment in Polish conditions. All systems include comprehensive monitoring and control with remote management capabilities.
