History

The Nishi-Nagoya Thermal Power Station began operations in 1970 as an oil-fired power plant operated by Chubu Electric. Unit 1 through unit 6 were constructed between 1970 and 1975. On September 14, 2010, Chubu Electric announced a renewal plan to replace the aging existing facilities with a high-efficiency natural gas-fired combined cycle power generation system.

Construction began on Units 7-1 and 7-2 on January 30, 2014. Unit 7-1 came on-line on September 29, 2017, and Unit 7-2 on March 30, 2018. Both Unit 7-1 and 7-2 use a Toshiba exhaust heat recovery multi-shaft 1,600 °C class combined cycle power generation system (MACCII) in which three generators are connected to three gas turbines and one steam turbine. [1] In order to transport the natural gas used at this power plant, a submarine tunnel with a length of 4.6 km extending from the Chita Daini Thermal Power Station was constructed. In March 2018, Guinness World Records certified the Nishi-Nagoya Thermal Power Station Unit 7-1 as the world's most efficient combined cycle power generation facility.[2]

In April 2019, the operations of Chubu Electric Power were transferred to JERA, a joint venture between Chubu Electric and TEPCO Fuel & Power, Inc, a subsidiary of Tokyo Electric Power Company.
