Inner Mongolia saw a sharp rise in the use of new energy storage systems in the first quarter of 2025, with charging volumes reaching 730 million kilowatt-hours—up 420% year-on-year—and discharging volumes totaling 630 million kilowatt-hours, a 446% increase from the same period last year, according to the regional Energy Bureau on May 12.

Inner Mongolia saw a sharp rise in the use of new energy storage systems in the first quarter of 2025, with charging volumes reaching 730 million kilowatt-hours—up 420% year-on-year—and discharging volumes totaling 630 million kilowatt-hours, a 446% increase from the same period last year, according to the regional Energy Bureau on May 12.
A bureau official noted that Inner Mongolia added 7.08 gigawatts of new energy storage capacity in 2024, 2.4 times more than the previous year. This pushed the region’s total installed capacity past the 10-gigawatt mark, making it the first in China to hit that milestone. As of now, cumulative capacity has reached 10.86 gigawatts, with projections indicating it could rise to 16 gigawatts by the end of 2025.
To ensure efficient deployment of energy storage resources, the region has rolled out a range of policies, including guidelines for independent energy storage projects. These systems now earn revenue through multiple channels, such as time-of-use electricity pricing, power market trading, and discharge-based compensation mechanisms.
One standout example is the Bailing Energy Storage Station in Sunite Right Banner, Xilin Gol League. Between January and April this year, the station delivered 40.35 million kilowatt-hours to the grid, achieving a utilization rate of 94%. It ran the equivalent of 116 full charge-discharge cycles—nearly one per day. By fine-tuning its operational strategy and tapping into the spot electricity market to “buy low and sell high,” the station secured an average price spread of RMB 0.35 per kilowatt-hour, generating solid economic returns.
