About the Model 501 / 701:

The Mitsubishi Hitachi Power Systems (MHPS) Model 501/Model 701 series gas turbines are single-shaft, axial-flow, heavy-combustion turbines whose current power output is in the range of 113-334 MW (in simple-cycle mode).


The sole application of models 501 and 701 is utility/industrial power generation, including combined-cycle and cogeneration duty (including IPP).


The original Model 501/Model 701 series of gas turbines was privately developed by Westinghouse. Subsequently, the design was further developed by Mitsubishi Heavy Industries and most recently by MHPS.


In production.

Total Produced:

By the first quarter of 2020, about 482 MHI 501/701 series gas turbine machines had been installed in 30 countries and territories worldwide.


The MHPS Model 501 / 701 series faces competition from the General Electric MS9001 (Model 9000/Frame 9) and Siemens' SGT5-2000/4000 series.


1) M501J and M701J gas turbines maintaining strong market presence; 2) MHPS joint venture breaks up; 3) JAC technology has leading position; and 4) Ability to use unusual feedstock is significant advantage.
