China launches world's largest AI battery cluster

At the end of December 2025, a significant advancement in global power infrastructure occurred as the premier electrochemical storage facility on earth, the Envision Jingyi Chagan Hada station, integrated with the national grid, according to PV Magazine. Boasting a 4-GWh capacity at its primary site, this development concluded the assembly of a 12.8-GWh storage collective spearheaded by Envision within Inner Mongolian territory.

Inner Mongolia functions as the primary "green power bank" for China, frequently generating wind and solar surpluses that far outpace local consumption. Integrating these immense storage reservoirs allows the province to eliminate the persistent loss of clean electricity while transforming the region into a dependable, high-volume energy artery supplying the wider nation.

Beyond the central hub, the network spans several districts including Alxa League, Xilingol League, Ulanqab, Hohhot, Ordos, and Bayannur, pushing the manufacturer’s regional footprint beyond 14GWh. To support this massive scale, the firm established a comprehensive local industrial ecosystem that handles everything from the fabrication of battery units to the automated management of the finished sites.

Official reports from early January stated that the flagship 4-GWh installation successfully cleared rigorous grid validation on its inaugural attempt, PV Magazine reports. The facility underwent exhaustive "three charge and three discharge" assessments alongside a 72-hour period of non-stop trial functionality, setting a domestic benchmark for testing large-scale storage.

The timing of this activation coincided with fresh directives from the NEA and the NDRC focused on elevating the quality of power grid expansion. These guidelines advocate for more versatile regulation and the coordination of vast resources, specifically encouraging the use of grid-forming tech and advanced research for installations in harsh climates.

The AI-driven systems utilised by Envision combine grid-following and grid-forming technologies, using a sophisticated three-tier framework to ensure immediate synchronisation. This digital architecture slashes the time needed for setup while lowering the risk of electrical fluctuations, essentially allowing GW-scale plants to support the grid the moment they are powered up.

PV Magazine also reports that this 12.8-GWh cluster is designed to participate directly in the electricity spot market. By pairing trading algorithms with grid-stabilising software, the system operates in a continuous cycle of forecasting, distribution, and autonomous refinement. This "Physical AI" methodology, which places intelligence directly within the battery cells and operational layers, is projected to boost the total financial yield over the project's lifespan by more than 20%.
