There are currently over 2,200 hydroelectric power stations in Japan, hydroelectricity being the main form of power generation in Japan until the 1970s. Many of these power stations are “pumped energy storage” stations.
The Okinawa Yanbaru Seawater Pumped Storage Power Station (沖縄やんばる海水揚水発電所, Okinawa Yanbaru Kaisui Yōsui Hatsudensho) was an experimental hydroelectric power station located in Kunigami, Okinawa, Japan and operated by the Electric Power Development Company. It was the world’s first pumped-storage facility to use seawater for storing energy.
The large capacity of pumped storage hydropower was built to store energy from nuclear power plants, which until the Fukushima disaster constituted a large part of Japan electricity generation. As of 2015, Japan is the country with the highest capacity of pumped-storage hydroelectricity in the world, with 26 GW of power installed.
Pumped storage type power plants have been developed in Japan since 1930. Tokyo Electric Power Co., Inc. (TEPCO) has 9 pumped storage power plants with approximately 10,000 MW in total, including one under construction.
Many of these power stations are “pumped energy storage” stations. Pumped hydro energy storage generates electricity by pumping water from a lower reservoir to an upper reservoir and using this water to generate power when needed.
Mixed pumped storage hydroelectric power plants are pondage type hydroelectric power plants added with pumped storage power generation systems to enable them to make large-scale daily adjustments to meet peak demand.
