[1][2] The reservoirs used with pumped. . Pumped storage hydropower (PSH) is one of the most-common and well-established types of energy storage technologies. During times of excess power and low energy prices, water is pumped to an upper reservoir for storage. Explore energy storage resources Gravity is a powerful. .
