What is pumped storage hydro (PSH)?

During periods of low energy demand on the electricity network, surplus electricity is used to pump water to the higher reservoir. When electricity demand increases, the stored water is released, generating electricity. Pumped storage hydro (PSH) must have a central role within the future net zero grid.

How does pumped hydropower storage work?

The technology absorbs surplus energy at times of low demand and releases it when demand is high. Pumped hydropower storage uses the force of gravity to generate electricity using water that has been previously pumped from a lower source to an upper reservoir.

What is pumped storage hydro?

A dynamic energy storage solution, pumped storage hydro has helped ‘balance’ the electricity grid for more than five decades to match our fluctuating demand for energy. Pumped storage hydro (PSH) involves two reservoirs at different elevations.

Does pumped storage hydropower lose energy?

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.
