New world record for GE’s HA GT

29 March 2018

GE Power has announced that on 27 March that the Chubu Electric Nishi-Nagoya power plant Block-1, which is powered by GE’s 7HA gas turbine, was recognised by Guinness World Records as the world’s most efficient combined-cycle power plant, based on its achieving 63.08 % gross efficiency.
The plant also utilises Toshiba steam turbine and generator technology.
With this latest achievement, GE’s HA turbine has been recognised for powering the world’s most efficient power plants in both the 50hz and 60hz energy segments. In June of 2016, GE Power and EDF were acknowledged by Guiness World Records for delivering the world’s most efficient combined-cycle plant at 50hz, powered by the 9HA turbine. The facility, in Bouchain, France, achieved an efficiency rate of 62.22 % net efficiency and was also the world’s first combined-cycle plant equipped with GE’s HA turbine.
GE supplied three 7HA.01 gas turbines to the Nishi-Nagoya Block-1 power plant, rated at 1188 MW. Its HA GTs are said to be the fastest growing fleet of gas turbines in the world, and have achieved more than 88 000 operating hours of experience globally.
