Ranked: Nuclear Power Capacity by Country
Nuclear power plays a crucial role in the energy transition. However, to meet the world’s growing energy demand, more capacity is needed.
As of late 2023, global nuclear energy capacity stood at 396 gigawatts (GW). An additional 299 GW is either in development or announced.
This graphic, sponsored by Range Funds, provides visual context to which countries are at the forefront of this capacity, using data from Global Energy Monitor.
Current Nuclear Power Capacity by Country
Presently, the U.S. holds the largest nuclear energy capacity, totaling 102 GW across 94 reactors. The nuclear plants are spread out across the country, with 28 states hosting at least one reactor.

The largest increase in prospective capacity is set to come from China, which is adding 118 GW. This represents a 204% increase relative to current levels. Meanwhile, India is expected to add 32 GW, representing a 420% increase in total capacity.
Russia (+21 GW), the UK (+15 GW), Türkiye (+15 GW), and France (+12 GW) are also planning to see relatively large increases in nuclear power capacity. Conversely, the U.S. (+7 GW) is only set to see a 7% boost.
A Look Ahead
In December 2023, 22 countries, including the U.S., France, and Canada, pledged to triple global nuclear energy capacity by 2050 to support the net-zero transition. As such, further additions may be announced. This could provide an opportunity for investors to capitalize on the bright future of nuclear power.
