About the Siemens SGT-800:

The Siemens SGT-800 (formerly Siemens GTX100 and earlier Alstom GTX100) is a single-shaft, heavy-duty, 50/60 Hz industrial gas turbine in the 40-60 MW power class.


The current application is electrical generation, including simple-cycle, combined-cycle, and cogeneration installations. To date, no machines have been ordered for mechanical load drive duty.


The SGT-800 was privately developed by ABB Stal, which later became a unit of Alstom.


In production.

Total Produced:

At least 267 SGT 800 (and earlier GTX100) machines have been installed.


Apart from gas turbine machines manufactured in the Russian Federation and Ukraine, the SGT-800 competes primarily with the General Electric LM6000 and the Frame 6B/C.


1) This 50/60 Hz machine is well positioned in an attractive power class; 2) SGT-800 has a simple design for ease of use and minimal maintenance and its small footprint allows for use in cramped locations;
3) Combined-cycle and cogeneration duty should be the bulk of activity; Europe to remain prime sales arena; and 4) The machine is ideal for midsize, non-grid-oriented power schemes.
