Cummins Inc. (NYSE: CMI) announced its Power Generation business has been selected to supply battery energy storage systems (BESS) for an undisclosed large U.S. data center project, according to a company press release.

The company said the project would represent its largest BESS deployment to date. The systems are designed to meet utility-defined requirements for managing AI-driven load fluctuations, mitigating load oscillations, and supporting ride-through performance at the utility interconnection point.

Cummins' BESS product line was launched in May 2025. Each unit carries a nominal capacity of 5 MWh and uses lithium iron phosphate battery chemistry with liquid cooling thermal management. The systems are designed for compatibility with multiple power conversion and energy management system ecosystems.

"This project is an important achievement for Cummins and reflects the confidence customers place in our ability to deliver innovative energy solutions at scale," said Jenny Bush, president of Cummins' Power Systems business.

The BESS units carry certifications including UL 9540A, UL 9540, UL 1973, NFPA 855, NFPA 68, IEEE 1547, and UL 1741 SA/SB. Cummins said the systems can be deployed as a bridge-to-grid solution, integrated with backup power systems, or incorporated into a broader microgrid architecture.

Cummins, headquartered in Columbus, Indiana, employs approximately 67,400 people worldwide and reported $2.8 billion in earnings on $33.7 billion in sales in 2025.
