Cummins Wins Largest BESS Contract, Supplying Battery Energy Storage for Major U.S. Data Centers
Cummins Inc. has been selected to supply battery energy storage systems for a large U.S. data center project, the Columbus, Indiana-based company announced on August 18, 2026.
The contract represents the company's largest battery energy storage system deployment to date and signals a growing role for the power generation giant in the rapidly expanding data center infrastructure market.
A Milestone for Cummins' BESS Business
The selection comes through Cummins' Power Generation business and marks what the company described as a significant milestone for its BESS operations.
The project adds to Cummins' existing presence in the North American data center market, where it already provides diesel standby and natural gas prime power solutions alongside its newer battery storage offerings.
Jenny Bush, president of Cummins' Power Systems business, called the contract an important achievement. "This project is an important achievement for Cummins and reflects the confidence customers place in our ability to deliver innovative energy solutions at scale," Bush said.
"As demand for data center capacity continues to grow, Cummins is well positioned to support customers with a broad portfolio of power solutions, from diesel standby and natural gas prime power to BESS and integrated microgrid solutions."
Cummins launched its BESS solutions in May 2025, positioning them as part of the company's broader commitment to supporting customers through the energy transition.
This latest contract demonstrates commercial traction for the relatively new product line within just over a year of its market introduction.
Designed to Manage AI-Driven Power Demands
The battery energy storage system selected for this project is designed to meet utility-defined requirements tied directly to the challenges posed by artificial intelligence workloads.
According to Cummins, the system addresses three specific operational needs: managing AI-driven load fluctuations, mitigating load oscillations, and enhancing ride-through performance at the utility interconnection point.
The BESS solution is built to rapidly charge or discharge in order to reduce demand spikes, improve power quality, and maintain a more stable load profile.
As AI workloads place increasingly unpredictable and intense demands on power infrastructure, the ability to smooth rapid fluctuations at the grid connection point has become a critical technical requirement for data center operators and the utilities serving them.
Cummins described the BESS solution as adding another layer of capability to the project's overall power architecture, complementing rather than replacing other generation assets on site.
Technical Specifications of the Cummins BESS Platform
The Cummins BESS solution deployed in this project carries a nominal capacity of 5 megawatt-hours per unit. The system uses lithium iron phosphate battery chemistry, a technology widely regarded in the industry for its thermal stability and cycle life.
Thermal management is handled through liquid cooling.
The platform features a flexible DC block architecture that the company says is compatible with multiple power conversion system and energy management system ecosystems.
Cummins designed the solution to be bridge-to-grid ready and capable of integration with both diesel and natural gas generators, reflecting the hybrid power architectures common in large-scale data center campuses.
The system carries multiple certifications, including UL 9540A, UL 9540, UL 1973, NFPA 855, NFPA 68, IEEE 1547, and UL 1741 SA/SB. Cummins said the platform was designed specifically for hyperscale workloads, with resilient operation as a primary engineering objective.
BESS as a Strategic Tool for Data Center Developers
Cummins framed the broader market context around intensifying grid constraints, growing interconnection queues, and rising energy costs, all of which are creating pressure on data center developers to find alternative strategies for securing and managing power.
In that environment, the company argued that battery energy storage is emerging as a strategic power enabler rather than simply a backup or auxiliary resource.
The company said BESS can help accelerate deployment timelines by serving as a bridge-to-grid solution while longer-term grid connections are established. It can also help operators maximize available grid capacity, manage peak demand, and satisfy utility-defined load management requirements.
These capabilities position BESS as a tool that can influence both the speed of a data center project's development and its ongoing operational performance.
Bush elaborated on the strategic value of the technology for data center operators.
"The future of data center growth depends on finding smarter, faster ways to deploy and manage power. BESS is quickly becoming a critical part of the modern data center power strategy," she said.
"From bridge-to-grid applications and peak demand management to long-term resiliency, BESS gives data center operators greater flexibility to deploy, optimize, and scale their power infrastructure."
Cummins' Broader Power Generation Portfolio
Cummins described its BESS offering as one component of a wider portfolio that includes advanced diesel, electric, and hybrid powertrains, integrated power generation systems, and microgrid solutions.
The company employs approximately 67,400 people worldwide and reported sales of USD 33.7 billion in 2025, generating net income of USD 2.8 billion.
It operates through five business segments: Engine, Components, Distribution, Power Systems, and Accelera by Cummins, the last of which encompasses its zero-emissions technologies, including battery and electric powertrain systems.
The data center contract announced in August 2026 follows a second-quarter 2026 earnings report in which the company raised its full-year financial outlook, suggesting continued commercial momentum across its businesses.
