Overview
Overview
The PGT25+/LM2500+G4 turbine draws its high efficiency and light weight from our aeroderivative technologies proven in energy applications and aircraft engines, while its ruggedness is inherited from our frame gas turbine designs.

Well-known technology
The PGT25+/LM2500+G4 is a proven design based on LM2500 gas generator technology with more than 100 million industrial operating hours, and aircraft engine experience with over 350 million flight hours.
Ease of maintenance and high unit availability
The package is preassembled and tested in our facility to minimize on-site assembly time. The gas generator and low-pressure turbine can each be easily and quickly removed and replaced, and full engine replacement performed in just 48 hours. An optional extended maintenance plan is available—increasing boroscope interval by 2,000 hours, hot section inspection by 5,000, and major inspection by 10,000.
Enhanced fuel flexibility
The turbine can operate on a wide range of liquid and gas fuels while reducing NOx and CO emissions to 25 ppm, thanks to its DLE1.5 combustion system.
