On July 31, the China National Energy Administration (NEA) held a regular press conference, during which it provided updates on China’s energy landscape for the first half of 2025, including the performance of renewable energy integration, summer peak power supply guarantees, and the release of the China New-Type Energy Storage Development Report (2025). Officials also responded to questions from journalists.
Steady and Rapid Growth of New-Type Energy Storage in H1 2025
Installed Capacity
By the end of the first half of 2025, China's new-type energy storage had maintained a stable and rapid growth trajectory. The total installed capacity reached 94.91 GW / 222 GWh, representing a 29% increase compared to the end of 2024. Among regions, Inner Mongolia and Xinjiang each exceeded 10 GW of installed capacity, while Shandong, Jiangsu, and Ningxia surpassed 5 GW. An additional 13 provinces, including Hebei, Zhejiang, Yunnan, Gansu, Guangdong, Anhui, Guangxi, Shanxi, Hunan, Henan, Hubei, Qinghai, and Guizhou, exceeded 2 GW.
Regional Breakdown
The main areas driving new-type energy storage growth in H1 were North China, Northwest China, and Southern China, which together accounted for over 80% of new capacity additions. Specifically, North China and Northwest China accounted for 29.7% and 25.7% of total operational capacity respectively, maintaining roughly the same share as the end of 2024. Southern China experienced the fastest growth, with its share increasing by 3 percentage points to 15.4%, primarily due to rising demand in provinces like Guangxi and Yunnan—regions with high hydropower penetration and relatively strong grid flexibility, but where rapid renewable energy development is tightening regulation capacity and increasing the need for storage solutions. In comparison, East China, Central China, and Northeast China accounted for 16.6%, 12.2%, and 0.4% respectively.
Utilization and Dispatch
According to preliminary statistics from grid operators, the average equivalent utilization hours of new-type energy storage nationwide reached approximately 570 hours in H1, up more than 100 hours year-on-year. Several provinces and regional grids—including Zhejiang, Guangdong, Gansu, Xinjiang, Hebei Southern Grid, and the Xinjiang Production and Construction Corps—reported strong dispatch performance, each exceeding 600 utilization hours, highlighting the growing role of energy storage in grid regulation.
Since July, many regions across China have experienced prolonged heatwaves, driving rapid increases in electricity demand. New-type energy storage has played a critical role in ensuring power supply. Notably, Jiangsu, Shandong, and Yunnan initiated province-wide coordinated dispatch of new-type energy storage stations during peak demand periods. The maximum discharge power reached 7.14 GW in Jiangsu, 8.04 GW in Shandong, and 4.74 GW in Yunnan, with dispatch availability rates exceeding 95%, significantly contributing to peak load support.
Highlights of the China New-Type Energy Storage Development Report (2025)
In the first half of 2025, investment in key hydrogen energy projects more than doubled. Several major green hydrogen projects in Jilin Province have accelerated their construction progress. Investment in charging and battery swapping infrastructure grew by nearly 70% year-on-year, with the first batch of large-scale vehicle-to-grid interaction pilots across nine cities actively advancing intelligent infrastructure deployment. Additionally, investments in new-type energy storage and integrated source-grid-load-storage systems increased by over 30% year-on-year.
