The General Electric LM2500 is a twin-spool, axial-flow, aeroderivative, 50/60 Hz industrial & marine gas turbine and gas generator in the 20-40 MW range. Current production variants are the LM2500 (22-24 MW); the 29-31 MW LM2500+ that adds an additional stage of compression for another 8 MW of simple-cycle output; the 33-37 MW LM2500+G4 featuring a modified first stage for increased air flow and pressure ratio; and the TM2500 mobile generation unit. To date, LM2500 engines have logged more than 75 million operating hours. Among other vessels, the LM2500 powers U.S. Navy DDG 51 destroyers, CG 47 AEGIS cruisers and Independence Class Littoral Combat Ships (LCS).
Utility and industrial electric power generation, including combined-cycle and cogeneration installations, various mechanical load drives, and marine propulsion.
The LM2500 was privately developed by the prime contractor. Thereafter, the U.S. Department of Defense, through the U.S. Navy, Naval Sea Systems Command, sponsored work on the LM2500 marine engine variants.
In production for all applications.
As of 2020, more than 2,300 LM2500 gas turbines, gas generators, and marine engines had been built and installed by GE and its affiliates.
In the electrical generation and mechanical load drive arenas, the gas turbines competing against the LM2500 include the Siemens SGT-600/700 and SGT-A65 TR, Mitsubishi/Pratt & Whitney Power Systems FT8, Hitachi H-25, and Zorya-Mashproekt UGT-15000. In marine propulsion applications, the LM2500 series faces competition mainly from the Rolls-Royce MT30 and the Zorya-Mashproekt UGT-25000.
Overall, there is little doubt that the LM2500 dominates the aeroderivative power generation and mechanical drive sectors. This position is unlikely to change in the coming decade. What is likely to change is the range of applications for which these gas turbines will be used as the full versatility of the LM2500 is exploited. It is apparent that this process is well underway, and particularly rapid growth in the use of the TM2500 is expected. The LM2500 is the leading candidate for the U.S. Navy's FFG(X) frigate.
