Ten Power Company
Structure The 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.
