MAPNA Group received the final acceptance certificate (FAC) for Steam Unit III of Parand Combined Cycle Power Plant on July 20, 2024.
Parand Combined Cycle Power Plant comprises of six gas-fired units running on V94.2 turbines, of which three have been upgraded to MAP2B turbine, MAPNA Group’s homegrown turbine which holds a higher efficiency rate.
With the permanent delivery of this unit, MAPNA Combined Cycle Power Plants Construction & Development Company (MD-2) has now received FAC for 123 units with an aggregate capacity of 19,185 MW.
With the addition of three steam units each with a capacity of 160 MW, Parand now functions as a combined cycle power plant with an increased efficiency rate of approximately 50 percent (53 percent for MAP2B power blocks), without any extra fuel consumption or hazardous emissions and a nominal capacity of 1500 MW.
The scope of the conversion project included the installation of three E-type steam turbines and generators with a nominal capacity of 160 MW, six HRSGs, an ACC cooling system, BOP (balance of plant), and a 400-kV generator station.
Key Features of Parand Power Plant
The plant is equipped with MAPEX, a steam turbine excitation system also developed by MAPNA Electric & Control Engineering & Manufacturing Company (MECO), for the first time.
Another homegrown equipment used in the plant is MAPCS, MAPNA Group’s locally manufactured distributed control system by MECO. It has been installed in steam unit III, running along Siemens control systems active in units I and II.
The development of MAPCS was the company’s response to the shifting climate in the power plant industry including technological advances, increasing demand for domestic equipment, rising cyber threats, and the need for smart process automation.
The control system can be employed in a wide range of industrial complexes, from power plants to oil & gas sectors and transportation systems.
Among other features of the plant is a MAPNA-developed sewage treatment complex of Parand county, a semi-arid region southwest of Tehran, which supplies the water demand for the steam portion.
The power plant is expected to play a critical role in supplying Tehran’s power demand during the peak season.
The first steam unit of the power plant was synchronized to the grid on November 8, 2016. The second unit was linked to the electricity network on August 22, 2018. Parand Power Plant is owned by MAPNA Parand Power Generation Company. A consortium comprising MAPNA Power Plants Construction & Development Company (MD-1) and MAPNA Combined Power Plants Construction & Development Company (MD-2) have constructed the power plant.
