Rather than run-of-the-river or storage-based conventional hydropower, pump-storage projects (a.k.a. pumped-storage hydroelectricity - PSH or pumped hydroelectric energy storage - PHES / " water battery ") use turbines in reverse to pump back water from a position of lower elevation to a water body of higher elevation when energy is cheap to provide peaking power / load balancing by running the water back down through the turbines when energy is more expensive and less available.
