Pumped-storage hydroelectricity (PSH), or pumped hydroelectric energy storage (PHES), is a type of hydroelectric energy storage used by electric power systems for load balancing. A PSH system stores energy in the form of gravitational potential energy of water, pumped from a lower elevation reservoir to a higher elevation.

Pumped storage power plants are currently the most economical way of efficiently storing large amounts of energy over a longer period. As the leading technology for energy storage services, pumped storage not only balances variable power production, but with its firm capacity it also serves as a reliable back-up.
One of these hydro power generation systems is a "pumped-storage system" , which pumps up water from a lower reservoir to a higher reservoir during off-peak hours and generates power by dropping water from the higher reservoir to the lower reservoir during peak hours. We manufacture an entire generation system for these power plants.
Their special feature: They are an energy store and a hydroelectric power plant in one. If there is a surplus of power in the grid, the pumped storage power station switches to pumping mode – an electric motor drives the pump turbines, which pumps water from a lower reservoir to a higher storage basin.
New pumped hydro storage technologies—such as variable speed capability—give plant owners even more flexibility by providing grid frequency support in both directions (in turbine and pump modes) as well as quicker response times.
