| Ten Power Company 
      StructureThe ten independent power 
      companies provide a stable electricity supply in their 
      areas.
  The ten privately-owned 
          electric power companies in Japan are responsible for providing local 
          operations from power generation to distribution and supplying their 
          respective service areas with electricity. Japan is a narrow country 
          that stretches from north to south with varying climate and geography. 
          Due to these factors, supplying energy to each region has its own special 
          characteristics. To meet local requirements, the ten companies operate 
          as independent suppliers, and thus are able to forge close relations 
          with local entities towards regional development. In March 2000 power 
          supply was partially liberalized to allow Power Producer Suppliers to 
          sell to extra high-voltage users(over 2MW). Regional companies were 
          also allowed to begin selling power to users outside their designated 
          area. All other users not targeted under the new liberalization guidelines 
          will continue to be served by their regional power company.
 
 
    National Cooperation The ten power companies 
      cooperate whenever needed for efficient operations.
   The ten power companies not only 
      serve their respective regional service areas but also cooperate with each 
      other to ensure a stable and efficient nationwide electricity supply. This 
      cooperative effort forms the basis for the companies to engage in 
      activities that transcend their allotted service areas for the benefit of 
      the entire electric power industry.The companies work 
      together to exchange electricity to provide power in the most efficient 
      manner possible in order to cope with emergency situations, from power 
      supply problems or failures to peak demand during the summer. To ensure 
      the smooth operation of power exchange, extra-high voltage transmission 
      lines link the entire country from Hokkaido in the north to Kyushu in the 
      south. These companies also take part in the cooperative development of 
      electric power technology and the sharing of resources.
