A 500 MW/2,000 MWh standalone battery energy storage system (BESS) in Tongliao, Inner Mongolia, has entered commercial operation after a five-month construction period. This reflects China’s accelerated rollout of large-scale storage to consolidate and integrate its high penetration of wind and solar energy.
The project was developed and financed by Tongliao Conch New Energy Co., Ltd., a subsidiary of Anhui Conch Cement Co. Ltd. (Conch Cement Group), and is located in Naiman Banner, Tongliao. The facility is the largest new single-site storage project in Inner Mongolia. Construction began on June 28, 2025, and the plant completed grid connection testing and final commissioning on November 28, 2025, one month ahead of schedule, with a total investment of approximately CNY 1.5 billion.
