Tehran’s largest rooftop solar plant comes online to plug shortages
The construction and grid connection of a 2-megawatt solar power plant at the Tehran International Exhibition Center has been completed, the Energy Ministry said on Friday, describing it as part of efforts to expand renewable energy capacity and strengthen electricity supply.
The ministry said the project was developed to meet a legal requirement for government entities to supply 20% of their electricity consumption from renewable sources, according to Mehr news agency.
The solar plant was completed in two phases and is now fully connected to the national power grid.
According to the ministry, the first phase of the project, with a capacity of 1.1 MW, was inaugurated in November 2025. A second phase with a capacity of 825 kilowatts was subsequently completed and connected to the grid.
With the addition of the new capacity, the Tehran International Exhibition Center solar plant has reached its final capacity of 2 MW, making it the largest rooftop solar power plant in Tehran Province, the ministry said.
In a statement issued on Friday, the Energy Ministry said it had launched a broad program since the beginning of last autumn to improve the readiness of the country's electricity network.
The statement said 14 major projects in the power sector have been implemented or are under implementation, including the expansion of thermal and renewable power generation capacity, the installation and development of smart meters, the modernization of transmission and distribution networks, the expansion of power substations and upgrades to grid infrastructure.
The ministry added that major and periodic maintenance work had been carried out on power generation units with a combined capacity of more than 110,000 MW as part of preparations for peak summer electricity demand, with most of the work completed before the start of the high-consumption season.
The statement said that during the recent US-Israeli 40-day war, about 4,200 MW of industrial power generation capacity was damaged and more than 6,000 locations in the electricity sector's facilities and equipment came under attack.
Despite the damage, reconstruction, repair and restoration work is proceeding rapidly, the ministry said, adding that electricity sector personnel are continuing to work around the clock to maintain services.
