J-Power to withdraw from Japan’s 153-MW Tokuyama

Electric Power Development Co. (J-Power), Japan’s largest electricity wholesaler, said March 13 it would withdraw from a plan to build the 153-MW Tokuyama hydropower plant in central Japan.

Chubu Electric Power Co., Japan’s third-largest utility, is to take over the plan to build Tokuyama in Gifu Prefecture. Chubu had planned to buy the project’s electricity from J-Power.

Tokuyama is expected to start generating by March 2015.

J-Power and Chubu originally had plans to build Tokuyama as a 400-MW pumped-storage project, to begin service in 2003.

That plan was delayed and revised in 2004 due to a government requirement that part of Tokuyama Dam’s proposed water storage for generation be changed to flood control capacity. As a result, J-Power and Chubu changed Tokuyama’s design from pumped-storage to a 153-MW dam-and-conduit project. At the same time, Chubu dropped plans to build the 24-MW Sugihara Dam to double as Tokuyama’s lower reservoir.
