The country's overall nominal capacity to generate electricity has increased by 381 MW over the past two weeks to reach 77,987 MW, Tasnim News Agency reported.
During the mentioned period, the first units of two combined-cycle power plants in Behbahan and Parand have been commissioned with each generating 160 MW of electricity.
A distributed generation power plant with a capacity to produce 61 MW of electricity has also been connected to the national grid.
In November 2015, Iran's former energy minister Hamid Chitchian unveiled plans to increase power generation capacity and exports to neighboring countries.
Iran is currently exporting around 12 billion kilowatt-hours (kWh) of electricity to its neighbors each year, whereas imports stand at 4 billion kWh annually, the minister said at the time.
Iran's electricity industry ranks 14th in the world and first in the Middle East in terms of generation capacity.
