According to incomplete statistics from TrendForce, the domestic energy storage bidding market experienced strong growth in September 2025, with newly added bidding volume reaching 14.73GW/41.54GWh, a quarter-on-quarter increase of 37%/8%. Specifically, the bidding volume for EPC projects was 12.9GW/33.58GWh, showing a year-on-year growth of 96%/89% and a quarter-on-quarter increase of 72%/41%. The EPC bidding scale in September reached a historical high, with large-scale projects being concentrated in regions such as Xinjiang, Ningxia, and Inner Mongolia. The newly added bidding volume for energy storage systems was 1.83GW/7.96GWh, marking a year-on-year increase of 96%/113% but a quarter-on-quarter decline of 44%/46%. From January to September 2025, the domestic energy storage bidding volume reached 102GWh, which is a year-on-year increase of 30%, indicating a robust bidding environment. With a tight supply of battery cells in September, prices for energy storage equipment have seen a rebound. Dongwu Securities stated in its report that independent energy storage is set to complement new energy supplies, with policies on capacity pricing gradually being implemented, enabling strong growth expectations for China's energy storage sector. CITIC Construction Investment has revised its forecast for new energy storage installations in the coming year to double due to an upswing in bidding conditions, active social capital investment, and improved economic feasibility, with many provinces becoming rich investment areas. Thus, driven by strong demand, total lithium battery demand next year is expected to exceed 2700GWh, with a year-on-year growth rate of over 30%, potentially leading to shortages in several links of the supply chain. Leading companies in the energy storage sector include: BYD COMPANY-100 (比亚迪股份), which started its energy storage efforts in 2008 and focuses on the technology research and development and application of energy storage systems and new batteries. BYD has established a complete industry chain covering the R&D, manufacturing, sales, service, and recycling of energy storage products, with applications ranging from power-side storage to grid-side storage, commercial and residential storage, as well as forklift and marine batteries. Leveraging its globally leading battery manufacturing technology and strong innovation capabilities, BYD's energy storage solutions have been supplied to hundreds of energy storage projects domestically and internationally. CATL (宁德时代) reported a net profit attributable to its parent company of 49.034 billion yuan for the first three quarters of 2025, marking a year-on-year increase of 36.20%. In the third quarter, the net profit reached 18.549 billion yuan, a year-on-year growth of 41.21%. With revenue growth and strong product demand, the gross margin for dynamic storage products has remained relatively stable, significantly enhancing its profitability. The rapid increase in energy storage demand both domestically and internationally provides development opportunities for the company. CALB (中创新航) reported a revenue increase of 31.7% to 16.42 billion yuan in the first half of its 2025 fiscal year, with sales of power batteries rising 9.7% to 10.66 billion yuan, while energy storage systems and other sales grew 109.7% to 5.76 billion yuan year-on-year. SHUANGDENG (双登股份), as a key player in AIDC energy storage, serves top internet and data center operators such as Alibaba, JD.com, and Baidu, and has become Alibaba's main supplier for energy storage in data centers. A company representative stated that a tenfold increase in AIDC energy consumption would imply a similar increase in backup power demand. More importantly, as the green electricity plus energy storage model is gradually promoted in data centers, the scale of energy storage systems is expected to far exceed traditional backup scenarios, potentially opening up broader development opportunities for the company.
