China’s National Energy Administration (NEA) has released the China New Energy Storage Development Report 2025, marking the first official and comprehensive government report dedicated to the country’s rapidly advancing new energy storage (NES) sector. The report, jointly prepared by the NEA’s Department of Energy Conservation and Scientific and Technological Equipment and the China Electric Power Planning and Engineering Institute (EPPEI), details the NES sector’s significant growth in 2024 and outlines strategic priorities for 2025.
The report draws in part on industry data, including contributions from the China Energy Storage Alliance (CNESA), which provided relevant data sets and research inputs to support the government’s analysis. CNESA’s involvement reflects the report’s collaborative yet government-led nature, ensuring data integrity and broad sectoral representation.
The most notable finding: by the end of 2024, China had reached 73.76 GW / 168 GWh in cumulative new energy storage capacity—an increase of more than 130% year-on-year. This figure accounts for over 40% of the global total, consolidating China's leading position in the international NES market.
This inaugural report provides an authoritative account of NES development across China, covering industry trends, policy advances, technological progress, and market performance in 2024. It also sets the direction for the year ahead under the framework of China’s “dual carbon” goals and the ongoing construction of a new power system.
Highlights from the 2025 Energy Storage Report
According to the NEA, 2024 saw the addition of 42.37 GW / 101 GWh in new NES capacity. The average storage duration rose to 2.3 hours, reflecting ongoing improvements in system design and grid integration. Northern and northwestern regions led deployment, with Inner Mongolia and Shandong among the top contributors.
Technology-wise, lithium-ion batteries remained dominant, comprising 96.4% of total installed capacity. However, the report notes growing deployment of alternative technologies such as compressed air storage, vanadium flow batteries, sodium-ion systems, and gravity-based storage—often through national pilot projects or demonstration zones.
The report also finds that storage systems are increasingly delivering value across multiple use cases. Independent and shared storage facilities now make up 46% of total capacity, while co-located storage with renewable energy accounts for 42%. Operational efficiency also improved significantly in 2024, with national average equivalent utilization hours increasing by 300 hours over the previous year.
Policy Outlook for 2025
Looking ahead, the NEA has identified five key priorities for 2025: advancing scientific planning, refining market participation mechanisms, accelerating core technology R&D, enhancing the multi-role of NES in the power system, and strengthening China's position in the global NES industry.
Work is already underway to draft the “15th Five-Year Plan” for NES, which will clarify national development goals, coordinate regional implementation strategies, and support industry standardization efforts.
The China New Energy Storage Development Report 2025 represents a major milestone in the institutionalization of NES planning and governance in China. By quantifying progress and clarifying national strategy, the NEA affirms its commitment to scaling advanced energy storage as a cornerstone of China’s future energy system.
