in a COGAS cycle. The LM2500 is license-built in Japan by IHI Corporation, in India by Hindustan Aeronautics Limited, and in Italy by Avio Aero. The LM2500/LM2500+ can often be found as turbine part of CODAG, CODOG, CODLAG propulsion systems or in pairs as powerplants for COGAG systems.

When coupled with an electric generator, it delivers 24 MW of electricity at 60 Hz with a thermal efficiency of 36 percent at ISO conditions. The improved, 3rd generation, LM2500+ version of the turbine delivers with a thermal efficiency of 39 percent at ISO conditions. When coupled with an electric generator, it delivers 29 MW of electricity at 60 Hz with a thermal efficiency of 38 percent at ISO conditions. The latest, 4th generation, LM2500+G4 version was introduced in November 2005 and delivers 47,370 shp (35,320 kW) with a thermal efficiency of 39.3 percent at ISO conditions. Derivatives The GE TM2500 is derived from the LM2500, and mounted on a trailer that makes it possible to move it to wherever 30 MW of temporary electricity generation is required. It can be installed
