Increase in Maximum Water Intake at Shinanogawa Power Station

East Japan Railway Company

April 22, 2011

With a tight electric power supply and demand situation in the Tokyo metropolitan region, East Japan Railway Company (JR East) has petitioned to increase the maximum water intake at the Senju and Shin-Ojiya power plants, part of the Shinanogawa Power Station (Ojiya City and Tokamachi City in Niigata Prefecture), a hydroelectric power station operated by JR East. Today, April 22, the Ministry of Land, Infrastructure, Transport and Tourism’s Hokuriku Regional Development Bureau provisionally granted permission to increase maximum water intake from the present 316.96 m3/s to 333.96 m3/s.

JR East is profoundly grateful for the understanding and cooperation of the local community and all concerned.
