China's energy storage sector is experiencing an unprecedented boom, with leading manufacturers operating at full capacity to meet soaring domestic and international demand. Analysts describe this surge as "one of the biggest surprises in China's energy sector this year."
Industry experts point to multiple driving forces behind this growth. Domestically, power market reforms and government subsidies have improved the economic viability of energy storage projects. Internationally, factors including AI data center expansion, aging European power grids, and renewable energy development in the Middle East have created strong demand for Chinese storage solutions.
Export figures highlight China's dominant position in the global market. From January to October this year, China exported over $65 billion worth of energy storage and EV batteries. The country's lithium-ion battery cell shipments are projected to grow 75% year-on-year in 2023.
Chinese manufacturers dominate global rankings, with six domestic firms - including Contemporary Amperex Technology (CATL), BYD, and Eve Energy - occupying the top spots in energy storage cell supply. The only non-Chinese company in the top 10, AES Corp, is majority-owned by a Chinese conglomerate.
Market analysts have revised growth projections upward. UBS recently increased its 2026 global battery storage installation forecast by 25%, while the IEA expects worldwide battery storage investment to reach $66 billion this year, with Chinese firms capturing most of this market.
The U.S. market presents both opportunity and challenge. While American data center growth creates strong demand, Chinese manufacturers face policy risks, including potential exclusion from tax credit programs. Currently, Chinese firms hold about 20% of the U.S. storage market share.
Domestically, China's power market reforms implemented in June have transformed storage economics by introducing market-based electricity pricing. This has increased daily operational hours for storage facilities by 0.78 hours compared to last year.
Policy support continues to strengthen, with 10 provinces introducing capacity pricing mechanisms and additional subsidies since late 2024. Analysts describe these measures as "the most decisive policy shift in energy storage in over a decade."
China's battery exports, including both energy storage and EV batteries, reached a record $66.76 billion in the first 10 months of 2023, surpassing solar components as the country's most valuable clean technology export. Industry projections suggest global storage cell shipments could grow 33-43% next year.
