Today, there is also a growing interest in small hydro facilities such as small dams that generate less than 10 megawatts of power and pumped storage hydroelectric plants.
Additionally, the pumped - storage plant itself effectively increased the company's efficiency (by pumping water to a holding pond at night thereby taking advantage of unused generating capacity) while improving its environmental credentials (the hydro plant emitted no air pollution).
Unlike conventional hydro, pumped storage plants can function as energy storage.
A veteran of the U.S. Submarine Service (one hitch) and a degreed Electrical Engineer (U.T. Knoxville — 1968 — three peer - reviewed IEEE papers published), I spent most of my career designing, building and commissioning electric power generating plants including hydro, pumped storage, coal fired, natural gas, nuclear (both PWR and BWR), geothermal, wood - waste, and landfill gas.
In the case of El Hierro, unlike most of the existing pumped storage systems worldwide, the reservoir has been created artificially just for storage purposes, instead of using an existing hydro power plant with a typical dam on a river used to create the reservoir.

Several other counties in the EU, do however have very large hydro capacities (there is 30GW in Norway alone) and some of these reservoirs are now being converted to pumped storage; e.g. Germany's Thuringia State has identified 13 potential sites, including 3 existing dams, for constructing pumped - storage plants that would total 5,130 MW.
