China's New Energy Storage Capacity to Exceed 370 Million kW by 2030

According to the recently releasedEnergy Storage Industry Research White Paper 2026, China's cumulative installed capacity of new energy storage is projected to surpass 370 million kilowatts (kW) by 2030.

In 2025, newly added capacity reached 66 million kW, representing a year-on-year increase of 51.9%. By the end of 2025, the total installed capacity of new energy storage in operation had reached 136 million kW, an 84% increase compared to the end of 2024.

The white paper indicates that as the proportion of new energy generation continues to rise, the power system's demand for long-duration regulation resources is becoming increasingly urgent. By 2030, the average duration of new energy storage is expected to approach 3.5 hours. This shift is expected to open the door to industrialization for long-duration technologies such as flow batteries and compressed air energy storage, accelerating the transition of energy storage from an auxiliary resource to a fundamental component of the power system.
