Iran has successfully added 290 megawatts (MW) of new electricity generation capacity to its national grid with the inauguration of the steam unit at the Dalahoo combined cycle power plant.
The milestone highlights Iran’s status as one of only seven nations in the world capable of manufacturing advanced F-class gas turbines.
Energy Minister Abbas Aliabadi inaugurated the new unit on Monday during a two-day visit to the western province of Kermanshah as part of the national Government Week celebrations.
The newly launched steam unit operates without consuming any additional fuel. Instead, it captures and utilizes the exhaust heat from the plant’s existing gas turbines, significantly boosting the facility’s overall energy efficiency and output.
The Dalahoo facility, the biggest combined cycle power plant in Iran, is designed with a total capacity of approximately 910 MW, comprising two 310 MW gas units and the newly activated 290 MW steam unit. With the steam unit now fully operational, the combined cycle has been successfully completed.
The gas units powering the Dalahoo plant rely on Iranian-made, cutting-edge F-class gas turbines.
The development and mass production of these high-efficiency turbines place Iran in an exclusive global club of only seven countries possessing the indigenous technological know-how to design and build them.
These advanced turbines are not being used in Iranian power plants for the first time. Iran’s domestic engineering conglomerates, most notably the MAPNA Group, have previously developed, tested, and deployed indigenous F-class models (such as the MGT-70) in other national power plants over the past few years.
By transitioning from older E-class models to highly efficient F-class turbines, Iran has drastically reduced its reliance on foreign suppliers like Siemens or GE.
This indigenous capability has effectively insulated Iran’s critical energy infrastructure from international sanctions while significantly lowering the fuel consumption and carbon footprint required per megawatt of electricity generated.
