Tohoku Electric Power Co., Inc. (東北電力株式会社 Tōhoku Denryoku Kabushiki Kaisha) is an electric utility, servicing 7.6 million individual and corporate customers in six prefectures in Tōhoku region plus Niigata Prefecture. It provides electricity at 100 V, 50 Hz, though some area use 60 Hz.

Tohoku Electric Power is the fourth-largest electric utility in Japan in terms of revenue, behind TEPCO, KEPCO and Chubu Electric Power.



On 11 March 2011 several nuclear reactors in Japan were badly damaged by the 2011 Tōhoku earthquake and tsunami. In the Onagawa Nuclear Power Plant a fire broke out in the turbine section of the plant.[1]

In order to make up for the loss of electricity from the damaged reactor plant, Tohoku announced it would restart a mothballed natural gas power plant. The liquefied natural gas and oil-fired No. 1 unit at the Higashi Niigata plant in Niigata prefecture has a 350-megawatt capacity and could be in operation by early June 2011.[2]
