context_page_description: Hydroelectricity is Japan's main renewable energy source, with an installed capacity of about 50 GW and a production of 69.2 TWh of electricity in 2009, making Japan one of the biggest hydroelectricity producers in the world.
  Most of Japanese hydroelectric power plants are pumped-storage plants. Conventional hydropower plants account for about 20 GW out of the total installed capacity as of 2007.
  Conventional hydropower potential of Japan is considered to be almost fully developed, with little opportunity for further capacity increase.
  In recent years, almost exclusively pumped storage plants were commissioned, significantly increasing the ratio of pumped storage capacity over conventional hydro.
  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.
