MAPNA-Developed MGT-75 Turbine Rotor Passes Overspeed Test Ahead of Deployment

The test was conducted on January 29, 2025, following low-speed and high-speed balancing operations.

Following completion of final assembly stages, the advanced next-generation turbine is scheduled for delivery to a power plant site by the end of the current Iranian year (March 2025). 

The testing took place at the upgraded testing and balancing facility of MAPNA Turbine Engineering and Manufacturing Company (TUGA), which recently underwent a comprehensive in-house modernization. 

The MGT-75 rotor was designed and manufactured using cutting-edge technologies in cooling systems and hot blade production, alongside a 3D aerodynamic blade design for both the compressor and turbine sections. It also incorporates an internally developed rotor cooling air path, a proprietary innovation by MAPNA Group. 

Throughout the MGT-75’s development, design and production technologies were entirely enhanced using domestic Iranian expertise. 

MAPNA’s new F-Class turbine not only meets global performance benchmarks but also addresses Iran’s electricity generation needs through modern technology, while positioning the conglomerate to compete in regional and international markets. 

The turbine enjoys a simple-cycle capacity of 222 MW and a combined-cycle capacity of 330 MW, with an efficiency of 39.1% in simple cycle and over 59% in combined cycle. This high efficiency significantly reduces fuel consumption and environmental emissions. 

A key feature of the MGT-75 is its ability to operate on hydrogen fuel alongside primary fuels (natural gas or diesel), drastically cutting carbon emissions from fossil fuel use.
