9HA.01/.02 GAS TURBINES (50 Hz)
THE WORLD’S LARGEST AND MOST EFFICIENT HEAVY DUTY GAS TURBINE The 9HA high efficiency, air-cooled gas turbine is the industry leader. With two available models—the 9HA.01 unit at 429 MW and the 9HA.02 unit at 519 MW—you can select the right capacity to meet your generation needs. 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 nearly 63 percent combined cycle efficiency, enable remarkably cost-effective conversion of fuel to electricity to help you meet increasingly dynamic power demands.
Industry-Leading Operational Flexibility for Increased Dispatch and Ancillary Revenue • Units offer fast, 12-minute ramp-up from start command to gas turbine full load. • Up to 70 MW/minute ramping capability is achieved within emissions compliance.

Full-Load Validation
• F eatures a less complex configuration than GE’s previous H-class units, and one that does not require cooled air.
•A t the heart of GE’s heavy duty gas turbine validation program is the advanced full-speed, full-load test facility in Greenville, SC.
• Modular systems ease installation and reduce onsite labor requirements by reducing field mechanical welds by 25 percent and reducing field installed valves by a factor of 10.
• Turndown as low as 30 percent of gas turbine baseload output is reached within emissions compliance.
• Maintenance is streamlined with quick- removal turbine roof, fieldreplaceable blades, and 100 percent borescope inspection coverage for all blades.
• Fuel flexible accommodates gas and liquid fuels with wide gas variability, including high ethane (shale) gas and liquefied natural gas.
• Simplified dual fuel system uses less water, eliminates recirculation, and utilizes enhanced liquid purge for improved reliability and dependability.
