China General Nuclear has announced a 6% rise in nuclear electricity production for 2024 compared to 2023, while China National Nuclear Corporation reported a 1.8% decline in its nuclear generation for the same period, primarily due to reactors being offline for maintenance.
In a statement to the Hong Kong Stock Exchange, China General Nuclear (CGN) indicated that as of December 31, 2024, it operated 28 power reactors with a total generating capacity of 31,798 MWe.
The total electricity generation from reactors managed by the group reached approximately 242.2 TWh last year, reflecting a year-on-year increase of 6.08%. Additionally, the total electricity supplied to the grid was 227.3 TWh, marking a 6.13% rise.
CGN completed 13 scheduled annual refuelling outages during 2024 (including one that extended into the next year), five ten-year outages (with one also extending into the next year), and one initial outage.
As of December 31, 2024, CGN managed 16 reactors under construction (including eight units managed under the direction of the controlling shareholder). Of these, two were in the commissioning phase, three in the equipment installation phase, two in civil construction, and nine preparing for the initial concrete pour. Unit 1 of the Huizhou/Taipingling plant in Guangdong province is anticipated to commence commercial operation in 2025.
On the other hand, China National Nuclear Corporation (CNNC) subsidiary China National Nuclear Power announced on the Shanghai Stock Exchange that its nuclear power units produced a total of 183.1 TWh of electricity in 2024, which is a 1.8% decrease year-on-year. The electricity supplied to the grid was 171.260 billion kWh, also showing a 1.8% year-on-year decline.
As of the end of December, CNNC controlled 25 operational power reactors with a total installed capacity of 23.75 GWe and had 18 units under construction or approved for construction, with an installed capacity of 20.641 GWe.
For 2025, CNNC aims for a nuclear power generation target of 195.4 TWh. The operational nuclear power units controlled by the company are planned to undergo 16 maintenance and refuelling outages throughout the year (including three ten-year overhauls, two five-year overhauls, and 11 routine overhauls).
While CNNC and CGN are the primary nuclear operators in China, the State Power Investment Corporation (through its nuclear business State Nuclear Power Technology Corporation) and Huaneng Group rank as the third and fourth nuclear operators, respectively. Other firms, such as Huadian, Datang, and Guodian, hold stakes in various plants.
China’s total fleet of 58 operational reactors supplies about 5% of the nation’s electricity.
