Global Nuclear Power Capacity Set to Surge by 75% Amid Renewed Energy Push
July 2025 — A massive expansion in nuclear energy is underway globally, with total nuclear power capacity poised to grow by over 75% in the coming years. According to the latest data from late 2023, global operating nuclear power capacity stands at 396 gigawatts (GW). However, if all planned and proposed projects come to fruition, capacity could soar to 695 GW.
China is leading the charge with the highest total nuclear capacity at 118 GW—though only 58 GW is currently operational. This reflects the country’s aggressive long-term strategy to become a dominant player in clean energy through nuclear power.
The United States remains the world’s leader in operational capacity, boasting 102 GW of its 109 GW total. This indicates the country’s mature and well-established nuclear infrastructure, even as it shows modest growth potential compared to rising economies.
France continues its historic reliance on nuclear energy, with 64 GW in operation out of a total 76 GW, highlighting the nation’s steady investment in the sector.
India presents a striking gap—of its 40 GW total capacity, only 8 GW is operational. This positions India as a future hotspot for nuclear development, potentially playing a pivotal role in the global transition to cleaner energy sources.
Other key players include Russia (50 GW total, 29 GW operational), South Korea (33 GW total, 27 GW operational), and the U.K. (22 GW total, 7 GW operational). Ukraine, Canada, and Türkiye also show promising development.
With nations turning to nuclear power as a solution for both clean energy and energy security, investment opportunities are growing. A call to “Consider investing in the future of nuclear power” highlights rising financial interest, particularly through instruments like the Range Nuclear Renaissance Index ETF (NUKZ).
The global nuclear renaissance is no longer a vision—it’s taking shape now.
