January 30, 2026 — The National Energy Administration held a regular press conference.
The National Energy Administration noted that as of the end of 2025, the installed capacity of new energy storage put into operation nationwide had reached 136 million kilowatts / 351 million kilowatt-hours, or 136 GW / 351 GWh. This represents an increase of more than 40 times compared to the end of the “13th Five-Year Plan” period, marking a leapfrog development. The average energy storage duration stood at 2.58 hours, an increase of 0.30 hours from the end of 2024.
North China and Northwest China were the primary growth regions, with newly added installed capacities of 21.88 GW and 19.66 GW, accounting for 35.2% and 31.6% of the national newly added capacity, respectively.
In terms of single-site scale, the trend toward large-scale development of projects exceeding 100 MW (100 megawatts) is evident.
Regarding application scenarios, the proportion of independent energy storage has increased. In 2025, the newly added installed capacity reached 35.43 GW, bringing its cumulative installed capacity share to 51.2%, an increase of approximately 5 percentage points from the end of 2024.
From the perspective of technological pathways, lithium-ion battery energy storage remains dominant, accounting for 96.1% of installed capacity. Compressed air energy storage, flow battery energy storage, flywheel energy storage, and other technologies together account for 3.9%.
