Frequently Asked Questions

What was the SGT-500 originally called?

The SGT-500 originated as the GT35, produced by Swedish company STAL-LAVAL, later becoming part of ABB and then Alstom before Siemens acquired the line.

Why does the SGT-500 have three shafts?

Three shafts (LP compressor, HP compressor/turbine, power turbine) allow each module to operate at its optimal speed, giving the SGT-500 excellent part-load performance and fuel flexibility.
