1. Scale of New Energy Storage Projects

Cumulative Power Storage Installed Capacity Reaches 164.3GW, Share of Pumped Storage Falls Below 40% for the First Time
According to incomplete statistics from the CNESA DataLink Global Energy Storage Database, as of the end of June 2025, China's cumulative installed capacity of power storage reached 164.3GW, a year-on-year increase of 59%. This year marks the final year of the "14th Five-Year Plan." Compared with the end of the "13th Five-Year Plan," significant changes have occurred in the structure of storage technology routes. The share of pumped storage has fallen below 40% for the first time, while new energy storage represented by lithium-ion batteries has achieved leapfrog growth. In addition, single-technology routes are accelerating toward diversification.

New Energy Storage Added 23.03GW/56.12GWh
In the first half of 2025, newly commissioned new energy storage projects reached 23.03GW/56.12GWh, with both power and energy scales increasing 68% year-on-year. Due to policy adjustments, project grid-connection timelines shifted earlier to "5·31." In May, new installations hit a record monthly high of 10.25GW/26.03GWh, a year-on-year increase of 462%/527%.

2. Shipment Situation of Chinese Energy Storage Companies in H1 2025
At the same time, Chairman Haisheng Chen also released the shipment data of Chinese energy storage technology providers and energy storage system integrators in the first half of 2025. CATL, CRRC Zhuzhou Institute, and Sungrow ranked at the top. The specific shipment situation is as follows:

2025.H1 Shipment of Energy Storage Batteries in the Global Market by Chinese Technology Providers
According to incomplete statistics from the CNESA DataLink Global Energy Storage Database, in the first half of 2025, shipments of energy storage batteries (excluding base station and data center cells) from Chinese companies to the global market reached 233.6GWh. Based on shipment volumes ≥50GWh, 20GWh≤shipment<50GWh, 10GWh≤shipment<20GWh, and shipment<10GWh, the shortlisted companies are shown in the figure below.

CATL still firmly holds the top position, while second-tier companies are rapidly narrowing the gap.

Note: (Companies within each range are listed in order of the initials of their short names in Pinyin.)
Statistical scope: Global shipment volume of energy storage cells (excluding base station and data center cells) independently produced by enterprises in H1 2025. Shipment volume is based on cells that have left the factory and been delivered to customers or project sites.

2025.H1 Top 10 Energy Storage System Integrators in the Chinese Domestic Market by Shipment Volume
In the first half of 2025, the Top 10 Chinese companies in terms of energy storage system shipments in the domestic market were, in order: CRRC Zhuzhou Institute, HyperStrong, Envision Energy, Sungrow, SCETL, XYZ Storage, ROBESTEC, XJ Electric, Goldwind, and ZTT.

3. New Energy Storage Tendering and Bidding Market

Scale of New Energy Storage Tenders and Bids
According to incomplete statistics from the CNESA DataLink Global Energy Storage Database, in the first half of 2025, China’s new energy storage tender and bid market grew significantly, especially the bidding scale of energy storage systems, reaching 86.2GWh, a year-on-year increase of 264%. The main reason was the surge in centralized procurement/framework procurement bidding scale, which increased 618% year-on-year. Several large-scale centralized/framework procurements announced bid results in the first half of this year, accounting for 69% of the total energy storage system bidding market, up 33% from the same period last year.

4. Market Outlook for New Energy Storage

Looking ahead to the "15th Five-Year Plan," new energy storage will be driven by the market. Combining its green value, it will continuously expand new application scenarios, innovate business models, and promote the industry’s upgrade toward high-quality development.
First, market participation progress will accelerate. The market-oriented development of energy storage has become inevitable. Facing different needs across regional markets in the future, more innovative business models will emerge.
Second, scientific planning and coordination will gradually be achieved. Energy storage will be more closely coupled with the construction of new power systems and achieve diversified applications in zero-carbon parks, green power direct connections, and other fields, expanding new business models.
Third, the construction of capacity mechanisms will accelerate. The role of new energy storage capacity is emerging. Reasonable evaluation of the capacity value and conversion methods of new energy storage, and its coordinated development with pumped storage and thermal power as regulation resources, will be the research focus.
Fourth, the market will drive industrial upgrading. China’s new energy storage business models have already shifted. Energy storage products with high technical performance, strong safety assurance, and reasonable costs will be more competitive in the market and will also promote the industry’s continuous upgrade toward high-quality development.
Looking to the future, CNESA forecasts that by 2030, China’s cumulative installed capacity of new energy storage will reach 236.1GW in a conservative scenario and exceed 291GW in an ideal scenario, with a compound annual growth rate of over 20% in the next five years. With the expansion of new scenarios such as desert-Gobi-wasteland large bases, zero-carbon parks, and virtual power plants, as well as collaborative innovation in materials, structures, and intelligent technologies, new energy storage will play a more central role in ensuring power security and achieving the "dual carbon" goals.
