The first and second steam units of Shirvan Combined Cycle Power Plant in Shirvan County, North Khorasan Province, will be launched next week, the managing director of Thermal Power Plants Holding Company said.
The two steam units, with a combined capacity of 320 megawatts, have cost $260 million, IRNA also quoted Mohsen Tarztalab as saying.
“The third 160 MW steam unit will come on stream by the end of the current fiscal [March 2020],” he added.
Shirvan Power Plant already has six gas units, each with a capacity of 155 MW (totaling 930 MW) and when all the three steam units become operational, its overall capacity will reach 1,410 MW.
Tarztalab noted that each steam unit will help save the plant as much as 250 million cubic meters of natural gas worth $50 million annually.
The addition of steam units to the plant is in line with the plan to convert simple-cycle plants into combined-cycle ones.
A combined-cycle power plant uses both gas and steam turbines to produce up to 50% more electricity from the same fuel input than a traditional plant. The waste heat from the gas turbine is routed to a nearby steam turbine that, in turn, generates more power.
In recent years, effective steps have been taken to convert conventional plants into combined-cycle ones to improve efficiency and reduce pollution and costs.
