The demands of today’s power generation industry are many: lower cost of electricity, dispatch volatility, along with increased efficiency, reliability, and asset availability. In response, GE created the 7F.05 gas turbine to be efficient and agile when you need it, yet still simple to maintain.

Industry-Leading Flexibility

Offers an 11-minute startup to an 80 percent load, as well as turndown to 24 percent of turbine baseload within emissions compliance, and can accommodate a range of fuels.

Efficiency

The 7F.05 achieves 60 percent efficiency providing customers with lower fuel costs and sets a new standard for F-class efficiency.

Lowest Lifecycle Cost in its Class

With an availability entitlement of over 97 percent coupled with improved maintenance practices and field removal compressor airfoils, the 7F.05 reduces replacement time, downtime, and costs.

7F.05 Gas Turbine (60 Hz)

In simple cycle, the 7F.05 gas turbine is extremely responsive with a start capacity of 241 MW in 11 minutes, 5 ppm NOx and grid stability logic, making it excellent for supporting renewable energy growth.

 

  • OpFlex advanced model-based control technology generates fast ramp rate of 40 MW per minute product features 
  • Full range of fuel variations (up to 15 percent Wobbe index)
  • Fuel flexibility includes natural gas, distillate oil, lean methane fuels, pure ethane, syngas, light crude oil, Arabian Super Light (ASL) crude oil, and a variety of other fuels
  • 14-stage compressor features 3D aerodynamic airfoils with superfinish for improved efficiency and reduced degradation
  • Field-replaceable blades for improved maintainability
  • Combustor features turndown to 24 percent of gas turbine baseload in simple cycle with autotune capability to accommodate wider fuel variation
  • 100 percent borescope coverage simplifies and fortifies inspections
  • Technical features help to lower starting emissions and fuel costs, while increasing spinning reserve capability and most importantly, revenue
  • Three stages of variable stator vanes enhance hot-day and part-load efficiency
