Underground pumped hydro storage utilizes abandoned mines as base assets to enhance the grid and add renewable energy. The facilities take advantage of geologic leverage with more energy storage capability while rebuilding retired mining towns that had once prospered.
[pdf] The 150 MW Andasol solar power station is a commercial parabolic trough solar thermal power plant, located in Spain. The Andasol plant uses tanks of molten salt to store captured solar energy so that it can continue generating electricity when the sun is not shining. .
This is a list of energy storage power plants worldwide, other than pumped hydro storage. Many individual plants augment by capturing excess electrical energy during periods of low. .
