What Can the New GT11N2 M Upgrade Do for You?

The new GT11N2 M upgrade bridges the gap between the latest technological developments and existing proven gas turbine designs to keep your plant competitive. It features completely redesigned turbine blading and is now successfully operating in multiple units worldwide.

The upgrade offers the possibility of operating the turbine in three different modes, depending on specific market requirements. All three modes can be selected on demand and online. This flexibility allows electricity costs to be continuously optimized.


  • Flexibility: three switchable operating modes for maximum extended lifetime or extra power output and efficiency
  • Reduced maintenance costs: extended service intervals of up to 48,000 equivalent operating hours
  • Performance: Up to 14 MW power output and up to 1.9% (add.) gas turbine efficiency
  MCL-Mode P-Mode L-Mode
Power output increase [MW] +14.3 +10.2 +4.2
Efficiency increase (add.) [%] +1.9 +1.8 +1.6
Interval extension [kEOH] 0 +12 +24

Basis: GT11N2 3VGV EV
All values at ISO conditions, base load, gas operation, GT only
Specific benefits in power output and efficiency are dependent on the status and limitations of the existing plant.
