Compressed air energy storage has been included as a key development focus in China's 14th Five-Year Plan for new energy storage technologies, with multiple regions introducing dedicated subsidy policies.
The trial effectively validated the system's capacity to guarantee supply security. By the end of July, within the service area of China's State Grid, the maximum dispatchable power from new-type energy storage reached 64.23 GW, with a real-time maximum discharge of 44.53 GW, up 55.7 percent from last year.
The country's new energy storage sector, which is currently in its early stages, is expected to evolve from a nascent market player to a global leader in the coming years, they said.
"Key developments in energy storage technologies will play a pivotal role in integrating renewable energy sources and smart grids, thus enhancing the overall flexibility and efficiency of China's energy system," said Fei Zhi, vice-chairman of GCL Group.
Chen Haisheng, Chairman of CNESA, noted: "China's CAES technology has advanced from 100 MW to 300 MW in a decade, setting a new global benchmark." The Energy Storage Industry White Paper 2025 reveals that global new energy storage installations reached 165.4 GW in 2024, with China contributing 43.7 GW of new capacity.
According to China's National Energy Administration (NEA), by the end of 2024, the total installed capacity of new energy storage projects in China reached 73.76 million kilowatts, representing an increase of over 130 percent compared to the end of 2023.
