Some hydropower facilities don't just generate power; they store it in the largest "batteries" on Earth. So-called pumped storage hydropower—also known as water batteries—can hold huge amounts of renewable energy for months at a time. This storage is very important.
However, pumped hydro continues to be much cheaper for large-scale energy storage (several hours to weeks). Most existing pumped hydro storage is river-based in conjunction with hydroelectric generation. Water can be pumped from a lower to an upper reservoir during times of low demand and the stored energy can be recovered at a later time.
Storage hydropower plants include a dam and a reservoir to impound water, which is stored and released later when needed. Water stored in reservoirs provides flexibility to generate electricity on demand and reduces dependence on the variability of inflow.
It serves as a crucial grid stabilizer, offering rapid-response energy supply during peak demand or fluctuations in renewable power. Pumped hydropower storage enhances grid reliability, ensuring uninterrupted operations for industries sensitive to power interruptions.
Rapid Response: Unlike traditional power plants, pumped storage can quickly meet sudden energy demands. Its ability to reach full capacity within minutes is essential for maintaining electricity stability and balancing grid fluctuations. Sustainability: At its core, pumped storage hydropower is a sustainable energy solution.
Energy Loss: While efficient, pumped storage hydropower is not without energy loss. The process of pumping water uphill consumes more electricity than what is generated during the release, leading to a net energy loss. Water Evaporation: In areas with reservoirs, water evaporation can be a concern, especially in arid regions.
The need for storage in electricity systems is increasing because large amounts of variable solar and wind generation capacity are being deployed.
The International Forum on Pumped Storage Hydropower was formed in 2020 to research practical recommendations for governments and markets aimed at addressing the urgent need for green, long-duration energy storage in the clean energy transition. This forum was formed by a coalition of 13 governments led by the U.S. Department of Energy, with former Australian …
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 hydropower (PSH) is a type of hydroelectric energy storage. It is a configuration of two water reservoirs at different elevations that can generate power as water moves down from one to the other (discharge), passing …
Why does renewable energy need to be stored? Renewable energy generation mainly relies on naturally-occurring factors – hydroelectric power is dependent on seasonal river flows, solar power on the amount of daylight, wind power on the consistency of the wind – meaning that the amounts being generated will be intermittent.. Similarly, the demand for …
Pumped storage hydropower (PSH) is a type of hydroelectric energy storage. It is a configuration of two water reservoirs at different elevations that can generate power as water moves down from one to the other (discharge), passing through a turbine. The system also requires power as it pumps water back into the upper reservoir (recharge).
