SGT-800 gas turbine highlights
Whatever the application, the SGT-800 meets your requirements for efficiency, reliability and environmental compatibility. As a result, you can expect lowest lifecycle cost of operation and the best possible return on investment.
The combustor and burner designs offer world-class emission performance over a wide load range with single-digit CO emission levels and capable of down to 9 ppm NOx emissions. Low emissions are also achieved with liquid fuel without the need of water injection.
Designed to reduce environmental impact, the SGT-800 gas turbine will help you meet even the strictest emission regulations worldwide.
Reliability has been a top priority from day one of the development of the SGT-800. Thanks to simple and robust technical solutions the reported average fleet reliability of the core engine and auxiliary systems lies at a world-class 99.8% for year 2018.
The SGT-800 offers broad flexibility in fuels, operating conditions, maintenance concepts, package solutions and ratings. These flexible solutions have been developed in order to satisfy your individual market-specific requirements.
The SGT-800 features a compact, modular, maintenance-friendly design. This maintainability combined with the turbine’s robust single-shaft arrangement, long time between overhauls and long lifetime ensures its high operational availability.
Flexible service concepts for on-site or off-site maintenance with possibility for 48-hour core engine exchange will maximize the availability even further.
With its high electrical efficiency the SGT-800 is the core of your power plant installation – from simple cycle to combined cycle operation, with single or multiple units.
Its excellent steam generation capability also makes the SGT-800 an ideal choice in combined heat and power (CHP) installations.

Ingenious design to the core
The SGT-800 industrial gas turbine combines a simple robust design for high reliability and easy maintenance with high efficiency and low emissions. The successive evolution of the SGT-800, based on experience of the installed fleet and on proven design solutions, ensures that you will get the optimal performance and lifetime out of your gas turbine.
The gas turbine features a robust dual-fuel DLE system for clean combustion, without the complexity of burner of burner staging.
The single-shaft engine is composed of a 2-bearing rotor with a 15-stage compressor and a 3-stage turbine.
Classic or single-lift?
Two different package solutions are available for increased flexibility in order to meet your individual requirements. Both are available for 50 Hz and 60 Hz markets.
Standard options for hot and cold climates are available for operation at extreme ambient temperatures.
SGT-800 classic package
The classic package consists of preassembled modules. The gas turbine and gearbox are placed on a single base frame. The mechanical auxiliary systems are mounted on a separate skid placed close to the gas turbine inside the enclosure.
Your benefit? A modular package that enables easy transportation and straightforward installation on site. Easy on-site maintenance inside the package, all inspections and overhauls are performed within the enclosure.

SGT-800 single-lift package
The single-lift package is a preassembled unit. This package is available in two configurations: Either as a single-lift driver unit (i.e. gas turbine, gearbox and mechanical auxiliary systems on a single base frame) with the generator on the foundation. Or as a complete skid-mounted train (including the generator) for 3-point mount installations, e.g. for power barges (SGT-800 SeaFloat).
Your benefit? A small footprint and the possibility of a 48-hour core engine exchange. The driver unit, or the complete train, is lifted in a single operation, which results in short installation and commissioning time on site. A special US-adapted option is available.

SGT-800-based power plants
Flexibility and efficiency are key for your power plant solutions. The excellent efficiency and steam-raising capability of the SGT-800 gas turbine make it outstanding in cogeneration – also called combined heat and power (CHP) – and combined cycle installations.
We offer you a broad range of power plant configurations based on one or multiple SGT-800 gas turbines. Within our standard plant configuration we can offer a high degree of scope flexibility. This enables plant optimization to suit your specific requirements, such as island-mode operation or multiple power blocks.
A scope to fit your needs
Whatever your application requirements, our flexible scope will fit your needs. We can offer a range of plant equipment – from gas turbine and steam turbine only, to full turnkey plant:
- Package
- Power island
- Power block
- Turnkey power plant
Designed for flexible operation
Our SGT-800-based power plants offer the flexibility required in today's volatile energy landscape: quick starts, fast load following and low emissions on low plant part-load operation. Designed for frequent starts and stops, they are the perfect match to back up renewable power sources in the grid.
Excellent combined cycle and combined heat and power efficiency
One or multiple SGT-800 gas turbines provide the core of a powerful combined cycle plant: In a 2x1 combined cycle configuration, the power output is up to 180 MW(e) at a net plant efficiency of more than 60%.
In a combined heat and power (CHP) cycle, the efficiency is more than 92% with supplementary firing.
Flexible maintenance – high availability
Our comprehensive portfolio of services provides low life cycle cost and optimum performance throughout the turbine’s life cycle: Long Term Programs (LTP), overhaul service, field service, spare parts, service exchange, remote diagnostic service, and modernization and upgrades.
With up to 60,000 equivalent operating hours (EOHs) between major overhauls the SGT-800 provides high operational availability.
Whether time-based or cycle-based, we offer flexible standardized maintenance concepts. On-site maintenance or modular overhaul, without the need for special workshop maintenance, is available for both package solutions. For the single-lift package, off-site maintenance with 48-hour core engine exchange is optionally available.
With its compact and modular setup, the SGT-800 gas turbine is designed for easy maintenance. The vertically split compressor casing enables easy access – a single blade or a single vane segment can be exchanged on site. For quick and easy inspections, the burners can be easily removed for maintenance.
Fuel flexibility matters
Whatever you need: The SGT-800 offers gas only, liquid only (Diesel No.2) or dual fuel (gas/liquid) with on-load fuel-changeover capability. The excellent fuel flexibility allows e.g. for high content of inert gases, hydrogen and heavy hydrocarbons in the gas fuel composition without any maintenance impact. The engine, equipped with DLE burners, is capable to burn up to 75 vol% of hydrogen (H2).
The low gas supply pressure requirement (27–31 bar[a] / 390–450 psi[a]) reduces the need for a gas compressor on site.
Best-in-class NOₓ and CO emission levels
All SGT-800 units are equipped with a robust dual-fuel Dry Low Emission (DLE) combustion system to minimize NOₓ and CO emissions. The combustor and burner designs offer world-class emission performance over a wide load range with single-digit CO emission levels and capable of down to 9 ppm NOx emissions. With this gas turbine you will comply with both global and regional regulations.
