Cummins to Supply Battery Storage for Undisclosed Large US Data Centre Project

Cummins has been selected to supply battery energy storage systems for what the company describes as a large US data centre project, marking what it calls the company's largest BESS deployment to date. Neither the project's location, capacity, nor contract value was disclosed in the announcement.

 

The battery system is designed to help manage utility-defined requirements around AI-driven load fluctuations at the data centre, mitigating load oscillations and supporting what the industry calls "ride-through" performance, the ability of a facility to maintain stable operation through brief grid disturbances rather than losing power. The system can rapidly charge or discharge to reduce demand spikes, intended to improve power quality and maintain a more stable load profile at the point where the facility connects to the utility grid.

Cummins' BESS product, launched in May 2025, uses a modular design built around 5 megawatt-hour nominal capacity units with lithium iron phosphate battery chemistry and liquid cooling thermal management, certified under a series of industry safety and performance standards including UL 9540A, UL 9540, UL 1973, NFPA 855, NFPA 68, IEEE 1547 and UL 1741 SA/SB. The company describes the system as compatible with multiple power conversion and energy management system ecosystems, and designed for integration alongside diesel and natural gas generators as part of a broader "bridge-to-grid" power architecture, rather than as a standalone renewable or emissions-reduction technology.
