In February 2025, China ended the requirement for new wind and solar projects to include energy storage, prompting storage providers to compete in the open market. Despite this, energy storage growth remained stable, with exports increasing 24% year-on-year.

By September 2025, installed capacity reached 100 gigawatts, marking significant growth. The sector faces challenges, including low utilization rates and profitability concerns amid geopolitical tensions.

Three income sources for energy storage include energy arbitrage, ancillary services, and capacity payments. Chinese firms signed 308 export deals in 2025, primarily with Europe, Australia, and the Middle East, although competition and pricing pressures pose risks to profitability.
