Posted June 5, 2026China’s nuclear power capacity nearly doubled since 2016 ›
Note: IAEA data are used to identify capacity additions in 2025 and 2026, which we then add to our International Energy Statistics estimate for 2024 to get the total capacities for 2025 and 2026. All values are in reference unit power.
From 2016 to 2024, China’s nuclear generation capacity increased 76% (24 GW), based on our International Energy Statistics (IES) data. According to the International Atomic Energy Agency’s Power Reactor Information System (PRIS), China added an additional 1.1 GW of nuclear power capacity in 2025 and 2.2 GW in 2026 (through May). China is continuing to build out its nuclear generating capacity and has 36 reactors under construction, accounting for more than 49% of total world nuclear construction, according to PRIS.
