GE’s gas turbine technology trend Advancing world class efficiency

Typical Efficiency vs. Temperature relationship

• H-class… >1430⁰C needed for >60% efficiency

• GE pioneered >1430C a decade ago with “H” class technology

• Six GE H-class units in operation >200,000 operating hours

• Last decade… steam cooling used

• Today… offering largest H-class GT with air cooling
