Guinness World Records recognized Chubu Electric Nishi-Nagoya Block-1 power plant as the world’s most efficient combined-cycle power plant. It is powered by GE Power’s 7HA gas turbine. The combined-cycle power plant achieved 63.08 percent gross efficiency during Guinness validation. In addition to the HA gas turbine, the facility utilizes Toshiba Energy Systems & Solutions’ steam turbine and generator technology.

GE supplied three 7HA.01 gas turbines to the Nishi-Nagoya Block-1 power plant, which provides more than 1,188 mw of power to the grid. This is the equivalent power needed to supply approximately 2.7 million average homes in Japan.
