Pumped hydro

Pumped-storage hydroelectricity (PSH) is a type of hydroelectric power generation that stores energy in the form of potential energy of water, pumped from a lower elevation reservoir to a higher elevation. Low-cost off-peak electric power is used to run the pumps, and ther stored energy can be used for load balancing.

During peak periods of electricty demand, the stored water is released through turbines to produce hydroelectricity. Turlough Hill (292 MW), operated by the ESB, is currently Ireland’s only pumped-storage hydroelectricity plant. However, this is likely to change shortly and ECOFACT have worked on a number of these schemes currently being progressed in Ireland.
