The Maysān power project is an 840MW gas-fired, combined-cycle power generation facility under construction in the Maysān Governate of Iraq.
It is being jointly developed by Maisan Power Company, a subsidiary of Raban Al Safina Group, and CITIC Construction Company with an estimated investment of approximately £1.6bn ($2bn).
Recommended White Papers
While the construction works on the project were started in June 2019, the gas turbines were hoisted and installed during September and December 2020.
The project is expected to commence operations by March 2021 and achieve full capacity by early 2022.
Once fully functional, the Maysān combined-cycle power plant is expected to supply enough electricity to power approximately three million Iraqi households and businesses.
Location
The Maysān combined-cycle power project is located approximately 20km southeast of Amara, in the Maysān Governate, in southern Iraq.
Maysān combined-cycle power plant make-up
The Maysān combined-cycle power plant will be equipped with two SGT5-4000F gas turbines, one SST5-4000 I-L steam turbine, and three SGen5-2000H generators from Siemens.
The facility will also feature SPPA-T3000 automation and control systems, transformers, associated electrical equipment, and the fuel gas system, along with waste heat recovery boiler equipment.
The gas turbines come with 15-stage axial flow compressor, and four-stage, air-cooled annular combustion system designed to operate at an exhaust temperature of 599ºC. The design incorporates the hydraulic clearance optimisation (HCO) technology to reduce clearance loss and increase gas turbine efficiency.
Designed to operate at a frequency of 50Hz, both the gas and steam turbines will have a speed of 3,000rpm.The gas turbines will have an efficiency of 58% in combined-cycle operations. The rated output of the gas and steam turbines will be 329MW each.
The other components of the power station will includes the fuel gas supply system with inlet filter, pressure regulating line, gas measurement and ignition gas system, heat exchangers, integrated water tanks, and bypass stacks.
Project funding
The Maysān combined-cycle power project is being funded by CITIC Construction Company, under a deferred payment agreement (DPA) through banks.
The lenders for the project include the Industrial and Commercial Bank of China (ICBC), the Export-Import Bank of China, and the China Minsheng Banking Corporation.
