The PGT25+G4 is a 34 MW gas turbine that draws its high efciency and light weight from GE’s aeroderivative
technology and its ruggedness from heavy duty gas turbine designs. Its high reliability and availability are
the result of its evolution from the proven LM2500+ and PGT25+ models, as well as advanced materials used
in GE aircraft engines, and heavy duty gas turbine technology.
The gas generator is based on the LM2500+ with minor enhancements to increase the ow and temperature
capabilities, while the power turbine is a 6100 RPM machine proven in the PGT25+ and capable of direct
coupling to the driven equipment for simplicity and improved efciency and maintenance. The annular
combustor is that of the LM2500+ with slight modications to impart higher ring temperature capability,
reduce the maintenance cycle time, and keep NOx at LM2500+ levels even at higher ring temperatures.
The enhanced PGT25+G4 package offers improved integration of auxiliaries, reduced installation and
commissioning time, and easy maintenability. Upgrade kits are also available for the the installed base
of PGT25+ units to increase output power by 10%.
