    The world's most powerful mobile gas turbine


    A dependable supply of electricity is at the very base of good living standards and economic growth. Several areas of the world continue to require the fast deployment of power solutions to quickly restore and upgrade a damaged or inadequate infrastructure, supporting developing economies or emergency disaster relief.

    With site installation in less than two weeks and an outstanding output of up to 44 MW(e), the SGT-A45 mobile gas turbine unit offers a cost-effective, dependable solution to these needs.
    Based on proven aeroderivative gas turbine technology, the SGT-A45 achieves the highest power density and fuel efficiency of all mobile power plants on the market. It can operate at either 50 or 60 Hz and offers a highly flexible solution for a wide range of applications.

    SGT-A45 mobile unit highlights

    The SGT-A45 achieves significantly higher power output and fuel efficiency than any other mobile gas turbine unit.

    This translates into direct savings in initial capital investment (US$/kW) and operating costs (US$/MWh).
    With these features, the SGT-A45 mobile unit offers you the best economics for fast power solutions.

    The SGT-A45 mobile unit utilizes trailer-mounted modules which can be rapidly deployed by air, land or sea and are pre-commissioned at the factory in order to reduce the installation on site to less than two weeks.
    The unit can generate electricity for 50 or 60 Hz power grids without any hardware modification.  

    The SGT-A45 is built with proven parts and advanced technology which has continuously been improved through extensive operational experience. The gas turbine utilizes proven components from both the Rolls-Royce Trent 800 with 28 million hours in flight and SGT-A65 (Industrial Trent 60) with more than 1.5 million hours in industrial applications. Considerable track record in naval marine propulsion completes the experience pedigree of this gas turbine technology.

    The performance advantage of the SGT-A45 mobile unit is amplified in hot climates: At 30 °C and in 50 Hz operation, the SGT-A45 still retains almost all of its ISO-rated output, without any auxiliary water injection. When water is used for low NOx emissions (25 vppm with gas fuel and 42 vppm with liquid fuel), the output rating curve is essentially flat, with virtually no loss in power output across an ambient temperature range that extends beyond 40 °C.

    No hot lockout or hot standby: Following shutdown from full power, the unit can perform a normal restart at any time. This is an inherent feature to the SGT-A45 gas turbine architecture, and does not require any additional equipment or special procedure.
