About the GE MS9001:

The General Electric MS9001 is a heavy-duty, single shaft, axial-flow, industrial gas turbine for 50 Hz operation, with power ratings up to 256 MW in simple cycle duty and up to 520 MW in combined cycle duty. Combined-cycle packages of up to 825 MW are currently advertised.


Baseload electrical power generation, including simple-cycle, combined cycle, and cogeneration installations. MS9001 machines can be equipped with GE's dry low NOx (DLN) combustion system. The MS9001 gas turbine machine has also been ordered for peaking duty.


The MS9001 was privately developed by General Electric.


Other than the MS9001EC, the MS9001 models identified are either currently in production or will enter production in the next few years. GE is not actively promoting the 9EC.

Total Produced:

A total of 1,186 50 Hz MS9001 gas turbines of various types have been manufactured and installed for customers in 51 countries.


With a simple-cycle output of 120 MW upward, the 50 Hz MS9001 competes against machines from Mitsubishi Heavy Industries (Model 501/701 series), and Siemens (SGT5-2000/3000/4000 series). Prior to General Electric's acquisition of Alstom, the MS9001 also competed against the Alstom GT13E2 and GT26. These engines are now part of GE's line of heavy-duty gas turbines.


1) Steady increase in world power demand points to slow but steady increase in additional capacity; 2) Increasing output of turbines means numerical increase may not match power increments; 3) MS9001E being supplanted by more modern variants; and 4) Upgrading turbines becoming increasingly important.
