(*Notes)

  1. As of April 2016, the following thermal power stations are off-line as planned for a long term: Goi (Units 1-6), Yokohama (Units 5-6), Kashima (Units 1-4), Ohi (Units 1-3) and Hirono (Unit 1).
  2. As of end of FY2016, the rated output is reduced from 710MW to 685MW as well as the power generation efficiency from 61% to 59% at Kawasaki Unit 2-2 and 3. This is due to an emergency construction work based on the defective cases of other companies' steam turbine.
  3. Generation Type
    Steam power: Steam power generation
    GT: Gas turbine generation
    CC: 1,100℃ class combined cycle generation
    ACC: 1,300℃ class combined cycle generation
    MACC: 1,500℃ class combined cycle generation
