The 954MW Urmia gas-fired power plant, located in the West Azerbaijan province of Iran, is being converted into a 1,434MW combined-cycle facility by adding three steam turbines in phase two.
Tadbir Sazan Saramad (TSS), a private joint stock company established by Pasargad Energy Development Company (PEDC), Arian MahTaab Gostar and Omid Taban Hoor, is the owner and developer of the project.
Construction on the gas section of the power station started in November 2004 and the plant commenced simple-cycle operations in 2008.
The first steam turbine of the plant was commissioned in August 2020, increasing the plant’s capacity to 1,114MW. The second unit is expected to come online in early 2022 followed by the commissioning of the third steam turbine by March 2023.

The combined-cycle power project is intended to increase the overall plant efficiency from 32% to 49%, while reducing gas consumption significantly.
Location and site details
The Urmia combined-cycle power project is located in the Rashkan Industrial Zone in Urmia County, West Azerbaijan Province, in north-west Iran.
The project site lies 35km away from the Urmia city on the road to Mahabad.
Urmia combined-cycle power plant make-up
The 1.4GW gas-fired combined-cycle power plant will feature three 160MW E-class steam turbines from Mapna Turbine Engineering and Manufacturing (TUGA), in addition to six existing V94.2 gas turbines also supplied by TUGA.
Four of the gas turbines are of 157.5MW capacity each, whereas as the remaining two are of 162MW capacity each.
The Urmia power plant operates on natural gas as the main fuel with oil used as the secondary fuel.
Other components of the plant include auxiliary boilers, gas pipelines, a gas pressure regulating station, compressed air system, two 20,000m3 fuel oil storage tanks, and water treatment and fire protection systems.
Power evacuation
The electricity generated by the Urmia gas-fired power plant is evacuated into the Iranian national grid through a 230kV transmission line.
