1 GE Power & Water GAS TURBINE . The World's Largest and Most Efficient Heavy Duty Gas TURBINE GE's 7HA gas TURBINE is the industry leader among H-class offerings and is available in two models the at 275 MW and the at 337 MW. Thanks to a simplified air cooled architecture, advanced materials, and proven operability and reliability, the 7HA delivers the lowest life cycle cost per MW for 60 Hz applications. The economies of scale created by this high power density gas TURBINE , combined with its more than 61% combined cycle efficiency, enable the most cost effective conversion of fuel to electricity to help operators meet increasingly dynamic power demands.
