China National Nuclear Corporation (CNNC) has announced the start of commercial operations on the 1,126 MW first unit at its Zhangzhou nuclear power plant, located in the Fujian Province, in south-eastern China. CNNC had connected the reactor to the Chinese grid in November 2024.
Zhangzhou-1 is one of six Hualong One reactors to be installed at the site. Unit 2 (also 1,126 MW) is currently under construction and is scheduled for 2025. China's State Council approved the construction of Units 3 and 4 (1 GW each) in September 2022, as Phase II of the Zhangzhou plant. Unit 4 began construction in early October 2024. Two additional 1 GW units are planned for the third phase of the nuclear plant. Once completed, the Zhangzhou nuclear plant is expected to generate 58 TWh/year of electricity.
At the end of 2023, China’s nuclear capacity reached 56.9 GW (with 56 operational reactors) and its nuclear power generation reached nearly 435 TWh (around 5% of the power mix). China targets 200 GW of nuclear capacity by 2035.
