Iran generated 5.4 TWh of nuclear power in 2025, among top 30 producers
Iran churned out 5.4 terawatt-hours (TWh) of nuclear electricity in 2025, placing it among the world’s 30 largest nuclear power producers, although output fell 23% from a year earlier, according to the latest Statistical Review of World Energy published by the Energy Institute (EI).
The report showed Iran’s nuclear electricity generation declined from 7 TWh in 2024 to 5.4 TWh in 2025. The drop came during a year in which Iran was targeted by US-Israeli attacks during a 12-day war in June.
According to Tasnim News Agency, Iran was among the limited number of countries producing nuclear electricity. Only 32 countries, including Iran, produced nuclear power in 2025.
Global nuclear electricity generation totaled 2,845 TWh in 2025, up 1.3% from the previous year, the EI report showed.
The United States remained the world’s top producer of nuclear electricity in 2025, accounting for 29% of global output, according to the EI report. China ranked second with a 17.1% share, followed by France with 13.7%.
The report also said the United Arab Emirates cranked out more than 39 TWh of nuclear electricity in 2025, up 0.4% from the previous year.
With 5.4 TWh of nuclear electricity made in 2025, Iran produced more nuclear power than the Netherlands and Taiwan, placing it 30th globally. The country accounted for 0.2% of worldwide nuclear electricity generation.
The Bushehr Nuclear Power Plant, Iran’s sole nuclear power station, has a net generating capacity of 915 megawatts (MW), amounting to about 1% of the country’s total electricity output capacity. The facility is in operation, while its second and third units are under construction.
Its first unit was built with Russian cooperation and was designed to generate 1,000 MW of power.
Mohammad Eslami, head of the Atomic Energy Organization of Iran, said in June that the Bushehr plant had been among the world’s top 10 nuclear facilities for the third consecutive year, receiving a perfect score of 100 out of 100 for safety and efficiency.
The assessment was carried out by inspectors and specialists from the World Association of Nuclear Operators (WANO) following visits to nuclear power plants around the world, Eslami said.
