GTES-25P gas turbine generator set rated at 25 MW

Packaged GTES-25P gas turbine generator set  is designed to produce and supply power for industrial and domestic consumption.

GTES-25P genset  can use associated oil gas as a fuel providing its utilization at oil & gas production and processing sites.


GTES-25P gas turbine generator set is  developed by OJSC «Aviadvigatel» on the basis of GTU-25P gas turbine with the PS-90EU-25 engine. This  engine is a modification of the high-performance PS-90A aircraft engine, which was the first Russian engine to get international airworthiness certificate and is successfully operated on Tu-204, Tu-214, Il-96-300, Il-76MF aircrafts and on the VIP-airliner of the Russian President - Il-96-300PU.

Gas turbine generator set can be used as the main or stand-by power supply, independently or  in parallel with other electric power supply sources. There is a provision of exhaust gas heat recovery in a waste-heat boiler, either hot water or steam.

The genset has got modular construction which is simple and convenient in service. It is equipped by all necessary support systems and accessories. GTES-25PA modification for indoor accommodation is also available.

In GTES-25P design advanced technologies were used as well as rich experience of OJSC Aviadvigatel gained from development and operation of gas turbine engines and generator sets.

  • natural gas as per GOST 5542 or OST 51.40;
  • associated petroleum gas, diesel and other fuels as agreed upon with Aviadvigatel OJSC.

Major Benefits:

  • minimal production facilities. Building of additional constructions is not required resulting in lower investment costs for construction project.
  • minimum amount of the attendance staff allows to decrease operating costs.
  • high performance and service life rate.
  • completely factory-assembled; minimum cost and duration of installation, commissioning and putting into operation;
  • low specific fuel consumption for electric power and heat generation to guarantee low power and heat cost price;
  • capability for parallel and auto mode operation for optimization of power safety therefore in the case of emergency power cutoff there is automatic transfer to local load. So the negative consequences of failure are excluded;
  • short turn-back period of genset - 3...5 years;
  • containerized modules design;
  • high reliability proved by experience in operation;
  • just-in-time qualified maintenance provided by the company specialists;
  • high efficiency in cogeneration cycle.
  • minimal repair and maintenance costs resulting in power and heat generation minimal prime costs.

The quantity of gensets in service and total running time are given on  REFERENCE LIST page.
