Highlights of the SGT-800 gas turbine

Within the 40 - 60 MW(e) range, the SGT-800 offers outstanding combined cycle efficiency, leading to lowest lifecycle cost of operation and best return on investment. Ist high steam-raising capability makes it an ideal choice for combined heat and power applications.

The SGT-800 offers best-in-class NOx emissions of ≤15 ppmvd on fuel gas. It meets most stringent regulations of emission regulations.

Load rejection capability with ample margin to trip speed

On-load fuel-changeover capability (gas to oil and oil to gas)

Flexible service concept for on-site maintenance - hot section "strip", modules or gas turbine replacement

SGT-800 core engine

The efficient cooling system and insulating thermal-barrier coating for the stage 1 turbine blades ensure optimal performance and long lifetime.
A hot climate option offers up to 26% higher power and more than 5% reduction in heat rate at high ambient temperatures.

SGT-800 classic or single-lift package

Two different package solutions are available for increased flexibility and in order to meet the individual requirements of different applications. Both package solutions are available for 50 Hz and 60 Hz markets.


A gas turbine package includes:
gas turbine, enclosure, base frame, air intake, exhaust collector, engine control system, fuel metering skid, lubricating systems, starter system, vibration monitoring system, fire fighting system, package ventilation system, instrumentation, gearbox (if needed)

SGT-800 based power plants

For combined cycle and cogeneration (combined heat and power - CHP), Siemens offers a broad range of power plant configurations and scopes based on the SGT-800 gas turbine. For combined cycle, 1x1, 2x1, or 3x1 configurations are part of the standardized portfolio.

Comprehensive portfolio of customer service activities

Our service offerings include Long Term Programs (LTP), overhaul services, field service, spare parts, reconditioning of components and modernization and upgrades.
With up to 60,000 EOH between major overhauls, the SGT-800 provides high operational availability.
Siemens specialists offer on-site support all over the world.

Fuel flexibility

The SGT-800 offers gas only or dual fuel (gas/ diesel no.2) capability with on-line fuel change over.

Other fuel options are available on request.

Gas supply pressure requirements: 27-30 bar(a) / 390-435 psi(a).

Best-in-class NOx emission levels

All SGT-800 units are equipped with a DLE combustion system to minimize NOX and CO emissions and ensure that the turbine complies with both global and regional regulations.

Technical data

Performance data for simple cycle power generation

*Options available for other gases within specification and dual fuel with gas and Diesel no 2.

**NOx emissions at 15% O2 on fuel gas (with DLE)

Standard design; ISO ambient conditions.
