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]
