The “2024 Statistical Report on Electrochemical Energy Storage Power Stations” highlights rapid expansion, larger project sizes, and continued improvements in operational efficiency and safety as key trends for the year.
Of this, 74% came from utility-scale assets over 100 MW, marking a clear shift toward large, centralized systems. By the end of 2024, China’s cumulative capacity reached 62 GW/141 GWh. Standalone storage and renewable-paired systems accounted for 95% of all installations.
Standalone energy storage was the primary growth driver, with 23 GW added – up 150% year-on-year and accounting for 63% of total new capacity. Large standalone projects achieved average daily charge-discharge cycles of 1.5 and a utilization index of 52%. There was significant improvement in China’s co-located segment, too.
