Changes to the development project for the Tokuyama Power Plant and Sugihara Power Plant

May 31, 2004

Electric Power Development and Chubu Electric Power have decided to change the development project for the Tokuyama Power Plant and Sugihara Power Plant based on the revision of the construction project for the Tokuyama Dam, and today made an announcement to that effect to the citizens of Fujihashi-mura, where the power plant was to be built, and other related parties.
Under the current project, Electric Power Development will develop the Tokuyama Power Plant, a pumped-storage power plant with a maximum output of 400,000 kW, for which the Tokuyama Dam constructed by the Japan Water Agency will serve as an upper reservoir, and the Sugihara Dam, constructed by Chubu Electric Power, which is downstream of the Tokuyama Dam, will serve as a lower reservoir. At the same time, using the Sugihara Dam, Chubu Electric Power is to develop the Sugihara Power Plant, a dam and conduit-type power plant with a maximum output of 24,000 kW.

Since August 2003, a variety of announcements concerning the construction project for the Tokuyama Dam have been made, including those concerning a drastic increase in the budget for dam projects, a revision of the flood control project of the Ibi River as a whole, and a reduction in new water demand in the reservoirs along the Kiso River. As a result, the Ministry of Land, Infrastructure, and Transport and the Japan Water Agency are now in the process of changing the "implementation plan for the Tokuyama Dam construction project."

At the beginning of April 2004, the Ministry of Land, Infrastructure, and Transport proposed that Electric Power Development and Chubu Electric Power should transfer part of its water capacity for power generation to flood control capacity, based on the changes to the flood control project for the Tokuyama Dam.
Electric Power Development and Chubu Electric have comprehensively considered the proposal, taking into account the importance of the Tokuyama Dam construction project on the national and local levels, and the management environment surrounding power generators. As a result, both companies have decided to accept the proposal of the Ministry of Land, Infrastructure, and Transport to revise the Tokuyama Power Plant project and halt the Sugihara Power Plant project.

Electric Power Development has decided to change the Tokuyama Power Plant from a pumped-storage power plant under the current plan to a dam-and-conduit-type power plant with a maximum output of 153,000 kW, and to complete its construction by the end of FY 2014.

Based on the change in the Tokuyama Power Plant from a pumped-storage power plant to a dam-and-conduit-type power plant, Chubu Electric Power has decided to halt the project for the Sugihara Dam and Sugihara Power Plant.

We would like to express our appreciation for the understanding and support of the authorities of Fujihashi-mura and the local residents since the announcement of the development project, and request their understanding concerning this change in the project.
