Rosenergoatom is the Russian nuclear power station operations subsidiary of Atomenergoprom. As of mid-2026, the company operates a total capacity of 19,719 MW across 27 working units. Russia's Energy Strategy to 2050 targets nuclear energy to reach 25% of power generation, requiring 20GW of new capacity by 2042, creating significant growth opportunities for Rosenergoatom.
Cyborg Score Rationale
Rosenergoatom holds a dominant market position as Russia's largest nuclear operator and a major global player in nuclear power generation. Recent technological advances (April 2026: minor actinides fuel program; Kursk II-1 reached full power in March 2026) and substantial investment in new capacity underscore operational strength. However, geopolitical constraints and international sanctions on Russia limit expansion prospects.
Top Insights
Operates 27 nuclear reactors with 19.7 GW capacity; newly commissioned Kursk II-1 reached full operational capacity in March 2026 after grid connection in December 2025
Advanced technological development: Beloyarsk NPP Unit 4 completed first-ever minor actinides fuel program in April 2026, a fourth-generation nuclear technology enabling fuel cycle closure
Russia's Energy Strategy targets nuclear share to grow from current 18% to 23.5-25% of power generation by 2042-2050, implying 20 GW of new construction—a core growth driver
Subsidiary of state-controlled Atomenergoprom; faces international sanctions and technology access restrictions impacting overseas expansion and equipment sourcing
