The 9HA high efficiency, air-cooled gas turbine is an industry leader among H-class offerings, and now the 9HA.01 is at the heart of the world's most efficient combined-cycle power plant. With two available models—the 9HA.01 at 446 MW and the 9HA.02 at 571 MW—customers can easily select the right capacity to meet their generation needs.

The world's largest and most efficient heavy-duty gas turbine.

Thanks to a simplified air-cooled architecture, advanced materials, and proven operability and reliability, GE's 9HA units deliver exceptionally low life cycle cost per megawatt. The economies of scale created by this high power density gas turbine, combined with its more than 64 percent combined-cycle efficiency, enables the most cost-effective conversion of fuel to electricity to help operators meet increasingly dynamic power demands.

  • features a fast 12-minute ramp-up from start command to full load, and up to 70 MW/minute ramping capability in a 1x1 configuration

  • showcases a simpler configuration than GE’s previous H-class fleet and doesn’t require a separate cooling air system.

  • The 9HA has undergone a full-speed, full-load validation test
