Ube power station
|This article is part of the CoalSwarm coverage of Japan and coal.|
Ube power station was a proposed 1,200-megawatt (MW) coal-fired power station in Yamaguchi Prefecture, Japan. (Osaka Gas, one of the original joint venture partners in the proposal, said that a tentative name for the project was Nishiokinoyama Power Plant.) J-Power announced the cancellation of the plant in April 2021.
The map below shows the city of Ube, the approximate location where the plant would be built.
In 2014 J-Power, Ube Industries, and Osaka Gas proposed a coal-fired power station of two units of 600 MW each for the city of Ube, with a planned completion date for the first unit in the early 2020s.
In June 2015 Japan's Environment Minister Yoshio Mochizuki said he planned to submit an objection to the power station, saying it was incompatible with Japan's target to cut CO2 emissions by 26 percent from 2013 levels by 2030.
In April 2019 Osaka Gas announced that "in light of the changing business environment of the electric power industry and future risks, Osaka Gas has decided to withdraw from this business project as a result of comprehensive consideration based on the company’s investment criteria." Osaka Gas has a 45 per cent stake in the joint venture company.
After Osaka Gas's departure from the project the Environmental Impact Assessment (EIA) was withdrawn. J-Power and Ube Industries, which respectively have 45 per cent and 10 per cent stakes in the joint venture, said they would suspend environmental assessment of the plant and reconsider options including reducing its proposed capacity to 600 MW or several smaller 300 MW integrated gasification combined cycle plants.
On April 16, 2021, J-Power announced it was scrapping the long-planned coal power plant in Yamaguchi prefecture due to an outlook for expanding renewables and lacklustre electricity demand. Japanese NGO Kiko Network reacted to the announcement, saying: "With the cancellation of this project, at least 3.6 million tons of CO2 emissions per year (0.3% of Japan’s total greenhouse gas emissions) will be avoided (in the case of one 600MW unit). We welcome today’s decision announced by J-POWER and Ube Industries, which is in line with our request."
