Electricity sector in China

Electricity sector of China
Data
Installed capacity (2023)2919 GW
Production (2021)8.5 petawatt-hour (PWh)
China remains heavily dependent on coal for generation of electricity
By 2025, Asia is projected to account for half of the world’s electricity consumption, with one-third of global electricity to be consumed in China.[1]

China is the world's largest electricity producer, having overtaken the United States in 2011 after rapid growth since the early 1990s. In 2021, China produced 8.5 petawatt-hour (PWh) of electricity, approximately 30% of the world's electricity production.[2]

Most of the electricity in China comes from coal power, which accounted for 62% of electricity generation in 2021[2] and is a big part of greenhouse gas emissions by China. Power generated from renewable energy has also been continuously increasing in the country, with national electricity generation from renewable energy reaching 594.7 TWh in Q1 2023, an increase of 11.4% year-on-year, including 342.2 TWh of wind and solar power, up 27.8% year-on-year.[3]

In 2023, China's total installed electric generation capacity was 2.92 TW,[4] of which 1.26 TW renewable, including 376 GW from wind power and 425 GW from solar power.[3] As of 2023, the total power generation capacity for renewable energy sources in China is at 53.9%.[5] The rest was mostly coal capacity, with 1040 GW in 2019.[6] Nuclear also plays an increasing role in the national electricity sector. As of February 2023, China has 55 nuclear plants with 57 GW of power in operation, 22 under construction with 24 GW and more than 70 planned with 88 GW. About 5% of electricity in the country comes from nuclear energy.[7]

China has two wide area synchronous grids, the State Grid and the China Southern Power Grid. The northern power grids were synchronized in 2005.[8] Since 2011 all Chinese provinces are interconnected. The two grids are joined by HVDC back-to-back connections.[9]

China has abundant energy reserves with the world's fourth-largest coal reserves and massive hydroelectric resources. There is however a geographical mismatch between the location of the coal fields in the north-east (Heilongjiang, Jilin, and Liaoning) and north (Shanxi, Shaanxi, and Henan), hydropower in the south-west (Sichuan, Yunnan, and Tibet), and the fast-growing industrial load centers of the east (Shanghai-Zhejiang) and south (Guangdong, Fujian).[10][better source needed]
