7HA.01/.02 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 7HA.01 at 275 MW and
the 7HA.02 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.

Industry-Leading Operational Flexibility for
Increased Dispatch and Ancillary Revenue
• Fast 10-minute ramp-up from start command to gas turbine full load.

• 0 MW/minute ramping capability within emissions compliance.

• eaches turndown as low as 25% of gas turbine baseload output
R
within emissions compliance.
• uel flexible to accommodate gas and liquid fuels with wide gas
F
variability, including high ethane (shale) gas and liquefied natural gas.

Least Complex H-Class Offering
• simpler configuration than GE’s previous H-class fleet and one
A
that does not require a separate cooling air system.
• he 7HA is now available with an air cooled generator for
T
simplified installation and maintainability.
• Modular systems ease installation with 10,000 fewer man-hours

than GE’s 7F.03 gas turbine.
• treamlined maintenance with quick-removal turbine roof, fieldS
replaceable blades, and 100% borescope inspection coverage for
all blades.
• Simplified dual fuel system uses less water, eliminates recirculation,

and utilizes enhanced liquid purge for improved reliability
and dependability.

Full-Load Validation
• t the heart of GE’s heavy duty gas turbine validation program is
A
the advanced full-scale, full-load test facility in Greenville, SC.
• est stand enables GE to validate the 7HA gas turbine over an
T
operating envelope larger than the variances an entire fleet
of turbines would experience in the field, an approach that is
superior to operating a field prototype for 8,000 hours.
