The Andimeshk III project, also known as the Taraz Peyriz power project, is a 546MW gas-fired combined-cycle power plant under construction in the Khuzestan province of Iran.
Taraz Pey Riz (TPR), a civil construction holding company based in Tehran, Iran, is developing the project with an estimated investment of £223m ($316m). TPR was formed as a subsidiary of Civil Pension Fund Investment (CPFIC) under the Ministry of Cooperatives, Labour and Social Welfare of the Islamic Republic of Iran in 1996.
Although the Andimeshk III gas-fired power project was conceptualised a decade earlier, the key contracts were awarded in December 2020 leading to the start of construction in May 2021.
Despite having an installed power production capacity of 84.5GW, approximately 80% of Iran’s electricity demand is met through aging thermal power plants. The Andimeshk III power plant will help improve the country’s electricity generation infrastructure, upon commencing operations in early 2023.
Location and site details
The Andimeshk III gas-fired combined-cycle power project is located near Andimeshk, in south-western Khuzestan, Iran.
The project site spans 50ha and lies approximately 10km away from the Karkheh Dam road.
Andimeshk III power plant make-up
The Andimeshk III project will comprise a gas-fired combined-cycle unit equipped with two 183MW MGT70 V3 gas turbines, two heat recovery steam generators (HRSGs), and one 180MW MST-54C steam turbine from MAPNA, a turbine engineering and manufacturing company based in Iran.
Each gas turbine will operate at an efficiency rate of 36.4%, while the combined steam generating capacity of the waste recovery boilers will be 290 tonnes per hour (tph).
The cooling system for the plant will comprise an air-cooled condenser (ACC) supplied by the MAPNA Group, which also provides its proprietary automation and process control system MAPCS for the project.
Power evacuation from Andimeshk III
The electricity generated by the Andimeshk III gas-fired power plant will be evacuated into the Iranian national grid through a 400kV power transmission line via a direct substation housing three power transformers.
The Andimeshk III combined-cycle power project is being financed through 50% contribution from the Mapna Group, while the remaining is being funded by CPFIC.
Contractors involved in the Iranian gas-fired power project
A consortium of MAPNA Group, MAPNA International FZE, and MAPNA Special Projects Construction and Development Company (MD3) was awarded an engineering, procurement and construction (EPC) contract for the Andimeshk III combined-cycle power project in December 2020.
The contractual scope includes design, manufacturing and supply of turbines, generators, waste recovery boilers, cooling and control systems, as well as transportation, installation, testing, and commissioning of the plant’s key equipment.
MD3, on behalf of the MAPNA Group, is responsible for the execution of the main project works.
Taraz Pey Riz engaged Niroo Consulting Engineers, a design and engineering consultancy firm based in Tehran, Iran, to provide engineering consulting and construction supervision services for the project.
Niroo Consulting Engineers also serves as a consultant for electricity transmission network connection as well as the gas transmission facilities for the project.
