Fourth Upgrade for GE LM2500

Posted on September 13, 2005

GE Energy’s aeroderivative division has launched its fourth significant rating increase of the LM2500 aeroderivative gas turbine technology. The latest machine, referred to as the LM2500+G4 is an upgraded version of the LM2500+ designed with greater power capabilities. It will be available in the fourth quarter of 2005. The improvements include technologies derived from GE’s flight engines and the LM6000.

The 34.3 MW LM2500+G4 will deliver up to 12% more power compared to its predecessor over a wide range of operating conditions, according to GE. This latest upgrade will give customers additional horsepower with the same engine efficiency and reliability as demonstrated by the LM2500 family. The LM2500+G4 can operate in both simple cycle and combined-cycle operation, and will be available in standard and dry low emissions combustion models capable of burning natural gas, fuel oil or both. The LM2500+G4, in combined cycle mode relative to the LM2500+, is expected to have an 8.5% power and 0.75% heat rate advantage.
