Press Release (Jul 26,2007)
Submission of an Application for the Emergency and Temporary Use of the TEPCO Shiobara Power Station to the Ministry of Land, Infrastructure and Transport
Today, The Tokyo Electric Power Company, Inc. (TEPCO) submitted an application for 
the emergency and temporary use of the Shiobara Power Station (location: Nasushiobara 
City, Tochigi Prefecture; capacity: 900,000 kW; pumped storage hydroelectric power 
station*1) in accordance with Article 23 of the River Law (permission for use of 
river water) to the head of the Kanto Regional Development Bureau of the Ministry 
of Land, Infrastructure and Transport.

The Shiobara Power Station was revoked of its license under Article 23 of the River 
Law by the head of the Kanto Regional Development Bureau on May 16, 2007, because of 
data falsification and defective paperwork. TEPCO is currently proceeding with 
measures to stop leakage from the upstream Yashio Dam balancing reservoir as we work 
towards reapplication under the Article 23.
Under this circumstance, the Niigata-Chuetsu-Oki Earthquake that occurred on July 16, 
2007, led to a shutdown of all units of TEPCO´s Kashiwazaki-Kariwa Nuclear Power 
Station, with no prospect for it to reopen this summer. If the weather grows very hot, 
peak demand may reach approximately 64 million kW. In order to ensure stable supply 
of power, TEPCO applied for a permission to use the river water under Article 23 of 
the River Law for a limited period so that we can use the Shiobara Power Station in 
this emergency in order to contribute to the steady supply of electricity, with the 
understanding of local residents.

TEPCO is making every effort to secure power supply in order to provide electricity 
to our customers without imposing any inconvenience.
Again, TEPCO sincerely apologizes to the public, especially to those living nearby 
the site, for the anxiety and trouble caused by of the recent earthquake.

*1:Pumped storage hydroelectric power station
    Because such power stations possess an outstanding characteristic of taking only 
    a few minutes to reach full output after starting and requiring only seconds to 
    adjust output, they can quickly adjust to sudden changes in electricity demand. 
    This enables them to play a major role in supplying power in the afternoon when 
    demand is highest.
