Tohoku Electric Power Co., Inc. has systematically promoted the replacement of aging thermal power stations and has developed the latest thermal power sources that are cost-competitive and contribute to the reduction of environmental impact.
Joetsu thermal power station No. 1 uses the JAC (J-series-air-cooled) gas turbine, which is the latest model of the J-series gas turbine with a turbine inlet temperature (TIT) of 1,600°C upgrade to TIT of 1,650°C, and started commercial operation in December 2022.
This thermal power station incorporates the latest technologies and knowledge throughout the plant, achieving the world's highest plant thermal efficiency of 63.6%. Compared to conventional gas turbine combined cycle power generation facilities, we have achieved improvements in facility operability such as shorter plant start-up time, faster power generation output change speed, and lower minimum output.
