According to Official Amount @sjchuneng, on January 23, the National Energy Administration (NEA) held a press conference where Bian Guangqi, Deputy Director of the Department of Energy Conservation and Technology Equipment, introduced the progress of new energy storage development in 2024. Bian emphasized that the central government and the State Council attach great importance to the development of new energy storage. In 2024, "developing new energy storage" was included in the government work report for the first time. The recently enacted Energy Law of the People's Republic of China stipulates the promotion of high-quality development of new energy storage and the role of various storage technologies in regulating the power system. The NEA has been actively implementing the "Four Reforms and One Cooperation" energy security strategy, scientifically coordinating new energy storage development, and promoting its transition to a high-quality growth phase, representing a new driving force in the energy sector. In 2024, new energy storage continued its rapid development, with installed capacity surpassing 70 GW. By the end of 2024, the cumulative installed and operational capacity of new energy storage projects nationwide reached 73.76 GW/168 GWh, approximately 20 times that of the end of the 13th Five-Year Plan and more than 130% higher than at the end of 2023. The average storage duration of new energy storage systems reached 2.3 hours, an increase of approximately 0.2 hours compared to the end of 2023. Operational efficiency also improved, with equivalent utilization hours of approximately 1,000 hours in 2024, according to statistics from grid enterprises. This contributed to the efficient utilization of renewable energy, peak-load management, and the safe and stable operation of the power system, strongly supporting the construction of a new-type power system.
The top five provinces and regions in terms of cumulative installed capacity of new energy storage were Inner Mongolia (10.23 GW/24.39 GWh), Xinjiang (8.57 GW/28.71 GWh), Shandong (7.17 GW/15.55 GWh), Jiangsu (5.62 GW/11.95 GWh), and Ningxia (4.43 GW/8.82 GWh). Ten other provinces and regions, including Hebei, Zhejiang, Gansu, Guangdong, Hunan, Guangxi, Henan, Anhui, Hubei, and Guizhou, each exceeded 2 GW of installed capacity. The distribution of installed capacity by region was as follows: North China (30.1%), Northwest China (25.4%), East China (16.9%), Central China (14.7%), Southern China (12.4%), and Northeast China (0.5%).
New energy storage stations are increasingly centralized and large-scale. By the end of 2024, projects with an installed capacity of 100 MW or more accounted for 62.3%, up by about 10 percentage points from 2023. Projects with an installed capacity of 10–100 MW accounted for 32.8%, while projects below 10 MW accounted for 4.9%. Projects with storage durations of 4 hours or more accounted for 15.4% of total installed capacity, a rise of about 3 percentage points compared to the end of 2023. Projects with durations of 2–4 hours accounted for 71.2%, while those with durations of less than 2 hours made up 13.4%.
