Iran has entered a landmark $25 billion agreement with Russia’s state nuclear corporation, Rosatom, to construct four nuclear power plants in the country, according to Iran’s state news agency IRNA.
Rosatom had earlier confirmed signing a memorandum of understanding with Iran on small-scale nuclear power plants but had not disclosed details. The finalized deal was signed during the World Atom Week (WAW) 2025 Atom Expo in Moscow, attended by an Iranian delegation led by Atomic Energy Organisation of Iran (AEOI) chief Mohamad Eslami.
AEOI spokesperson Behrouz Kamalvandi announced that Iran and Russia concluded negotiations for five power plants larger than the Bushehr facility. Of these, four new units with a combined capacity of nearly 5,000 megawatts will be constructed in southern Iran, with each plant generating approximately 1,200 megawatts of electricity.
Kamalvandi described the Moscow trip as multi-purpose, involving participation in the summit, a policy address by Eslami, and pursuing expanded nuclear cooperation with Russia.
He praised Moscow’s role in the Bushehr Power Plant project, stressing that the plant fully complies with international standards and has contributed significantly to Iran’s energy infrastructure.
The agreement was finalized during World Atom Week 2025, the largest global nuclear forum, which also marked the 80th anniversary of Russia’s nuclear industry.
The event featured an address by Russian President Vladimir Putin and participation from high-profile figures, including International Atomic Energy Agency (IAEA) Director General Rafael Grossi, who also held talks with the Russian president.
Iran highlighted its latest nuclear achievements at a dedicated pavilion during the expo, held from September 25 to 28, which drew interest from international delegates and industry experts.
The deal underscores deepening nuclear cooperation between Tehran and Moscow and signals Iran’s intent to boost domestic energy production while strengthening its partnership with Russia.
