Inner Mongolia Energy Group has started construction work on a 605 MW/1,410 MWh energy storage plant in the Ulan Buh Desert, near the city of Bayannur, close to the border with the state of Mongolia, in a bid to accelerate large-scale renewable energy development in the sunny autonomous region.
The facility represents the first phase of the Dengkou Renewable Energy Storage Project with a total size of 1,000 MW/2,290 MWh and has a price tag of RMB2.1 billion ($295 million).
The first phase storage facility will feature a mix of energy storage chemistries, with 505 MW/1,010 MWh coming from lithium iron phosphate battery storage and 100 MW/400 MWh from all-vanadium liquid power battery energy storage capacity.
The winning bidders for the project’s lithium-ion battery energy storage component were announced on the day of the groundbreaking ceremony on September 5, with Xuji Electric taking first place among the bidders with a bid price of RMB0.495/Wh ($0.070/Wh ). ).
The project, billed as the largest single-capacity energy storage station under construction in China, is expected to be connected to the grid by the end of this year. Once completed, the storage system will largely supply green energy to the Beijing-Tianjin-Hebei cluster.
Inner Mongolia is the province with the highest coal production capacity in China, but also with ambitious plans to harness its abundant wind and solar energy potential.
