CNESA's 2024 Energy Storage Data Released

On January 15, the press conference for the 2025 Energy Storage International Summit and Exhibition (ESIE 2025) and the release event of the 2024 annual energy storage data by CNESA DataLink were held in Beijing.

Chen Haisheng, Chairman of the China Energy Storage Alliance and Director/Researcher at the Institute of Engineering Thermophysics, Chinese Academy of Sciences, provided a comprehensive summary of the development of new energy storage industries in 2024 and offered insights into the trends for 2025. Yu Zhenhua, Executive Deputy Chairman of the China Energy Storage Alliance, reported on the preparation status for the 13th ESIE 2025. Liu Wei, Secretary-General of the Alliance, and Tang Yuanyuan, Executive Deputy Chairman of the Alliance and General Manager of CRRC Zhuzhou Institute's Integrated Energy Business Division, among other leaders from council member units, were present to witness the event.

During the event, the "Global Energy Storage Database Mobile App" was also launched. This innovative data product integrates core functionalities from the CNESA global energy storage database, lectures, community forums, and industry news, transitioning tools from PC to mobile platforms to enhance user experience.

Cumulative installed capacity of new energy storage reached 78.32 GW, surpassing pumped hydro storage for the first time. According to incomplete statistics from the CNESA DataLink Global Energy Storage Database, by the end of 2024, China's cumulative installed capacity of power storage exceeded 100 GW, reaching 137.9 GW. The installed capacity of new energy storage surpassed that of pumped hydro storage for the first time, reaching 78.3 GW/184.2 GWh, with year-on-year growth rates of 126.5% and 147.5% for power and energy capacities respectively .

CNESA predicts that in 2025, new energy storage additions will be between 40.8 GW and 51.9 GW, averaging around 45 GW. Five significant trends are expected: increasing value in large-scale regulation and supply assurance; evolving participation in electricity markets towards multi-use and time-sharing models; intensified industry shakeout; technological innovation driving the industry from competing on price to competing on value; and an estimated breakthrough of 100 GW in cumulative installed capacity of new energy storage .

The 13th ESIE 2025 will take place from April 10-12, 2025, at the Capital International Exhibition Center in Beijing. It promises to break records with over 160,000 square meters of exhibition space across six pavilions, sponsored by leading companies such as Sungrow, ZTT, CATL, Xinyuan Intelligence, Higee, and CRRC Zhuzhou Institute. Yu Zhenhua highlighted six key features of ESIE 2025 during the press conference, emphasizing its scale, high standards, professionalism, market orientation, international scope, and strong influence .
