China's energy storage market: By 2025, China's energy storage market will develop rapidly, with newly operational new energy storage projects reaching an installed capacity of 66.4GW/189.5GWh, a year-on-year increase of 51.9%/72.6%, accounting for 58.6% of the world's newly installed capacity. The cumulative installed capacity of power storage projects that have been put into operation in China has reached 213.3GW, a year-on-year increase of 54%. Among them, the cumulative installed capacity of new energy storage has reached 144.7GW, accounting for more than 2/3 of the total domestic power storage capacity.
Regional distribution: China, the United States, and Europe are still the three largest regions in the global energy storage market, but the energy storage markets in the Middle East, Latin America, and other regions are rapidly rising, and the regional structure of the global energy storage market is continuing to diversify.
Technical route: Lithium ion batteries still dominate, but the technological structure is gradually showing a trend of diversification, and the proportion of long-term energy storage projects is constantly increasing.
Enterprise shipment situation: Chinese companies such as CATL and Sunac occupy a leading position in the global energy storage market.
Market Analysis
Bidding Market: In 2025, the domestic energy storage bidding market will be active, with 2594 bidding information and 2210 winning bid information released throughout the year, a year-on-year increase of 5%. EPC continues to dominate the bidding market, and the number and market share of energy storage system bidding companies continue to increase.
CNESA Energy Storage Index: The CNESA Energy Storage Index has risen by 41.7% for the whole year of 2025, significantly outperforming the Shanghai Composite Index and the Shanghai and Shenzhen 300 Index during the same period, and its overall performance is relatively stable.
Standard system: In 2025, the energy storage safety standard system will be strengthened, and the mandatory national standard GB 44240 will be officially implemented. The focus of safety protection will be shifted towards "dual carbon", and energy storage carbon footprint accounting standards will begin.
Policy interpretation
Market oriented construction: In 2025, the market-oriented construction of energy storage will accelerate, and the "Document No. 136" will reshape the development logic of the energy storage industry. The electricity market system will gradually improve, the time of use electricity pricing mechanism will deepen its connection with the market, and the implementation of capacity pricing policies will be accelerated.
High quality development of the industry: Focusing on the high-quality and large-scale innovative development of the new energy storage industry, we have released the "Action Plan for High quality Development of New Energy Storage Manufacturing Industry" and the "Special Action Plan for Large scale Construction of New Energy Storage Industry (2025-2027)".
Whole life cycle management: Strengthen project management, and the management of development rights transfer is showing a tightening trend; Strengthen operation and maintenance security, issue multiple policies to increase security inspection requirements.
Market Summary and Development Forecast
Market characteristics: In 2025, the Chinese energy storage market will exhibit characteristics such as scale leap, mechanism reshaping, scenario resonance, cycle refinement, global competition, innovation advancement, standard building, and capital empowerment.
Development forecast: It is expected that the cumulative scale of new energy storage will reach over 370 million kilowatts by 2030, with a conservative scenario of a compound annual growth rate of 20.7% from 2026 to 2030; In an ideal scenario, the compound annual growth rate from 2026 to 2030 would be 25.5%.
Future trend: During the 15th Five Year Plan period, the application pattern of the energy storage market will face multiple intertwined variables. Independent energy storage on the grid side will continue to be the main growth driver, while the demand for distribution and storage on the power generation side will rigidly rebound. The demand on the user side will increase, but the overall proportion is uncertain. The average cumulative installed time of energy storage will further increase, with projects lasting 4 hours or more becoming the new mainstream.
Research Conclusion
The energy storage industry in China is undergoing a profound transition from "scale expansion" to "value creation". Energy storage is no longer an auxiliary supporting unit of the power system, but is becoming a key variable in reshaping the operational logic. In the future, China's energy storage industry will continue to unleash its development potential and play a more important role in the global energy transition process, driven by technological innovation, market mechanisms, and industry synergy.
