Cummins selected to supply battery energy storage systems for large U.S. data center project

Key Terms

bess technical

BESS stands for Battery Energy Storage System, a technology that stores electricity for later use. Think of it as a large rechargeable battery that can hold excess power generated during times of low demand and release it when usage is high, helping balance supply and demand. This is important for investors because it supports the stability of energy grids, enables the integration of renewable sources, and can create new opportunities for profitability in the energy market.

ride-through performance technical

The ability of electrical equipment—such as inverters, generators, or power electronics—to stay connected and keep operating during short-term grid disturbances like voltage sags, frequency dips, or brief outages. Think of it like a car that can keep rolling over potholes without stalling. Investors care because strong ride-through performance affects product reliability, compliance with utility rules, and the likelihood of service interruptions or penalties, which can influence sales, contracts, and long-term revenue.

lithium iron phosphate (lfp) technical

A lithium iron phosphate (LFP) battery is a common type of rechargeable lithium-ion battery that uses iron and phosphate in its internal chemistry, prized for being stable, safe and long-lived. For investors, LFP matters because it trades higher safety and longer life for lower energy density—think of it as a sturdy, long-lasting suitcase that holds less per pound—so it affects product cost, vehicle range and total lifecycle value.

liquid cooling thermal management technical

Liquid cooling thermal management uses circulating liquids and related hardware (pumps, cold plates, pipes, and heat exchangers) to carry heat away from electronic equipment or industrial systems. It matters to investors because it affects product performance, reliability, energy use and operating costs—allowing denser, faster systems or lower power bills much like a car radiator lets an engine run harder without overheating, which can influence capital spending, margins and resale value.

ul 9540a regulatory

UL 9540A is a laboratory test method that simulates how energy storage batteries can fail, catch fire, and spread heat, gas, or flames to nearby cells or equipment. For investors, passing this test can reduce regulatory hurdles, insurance costs, and safety risk—think of it like a crash test for battery systems that shows whether a product is likely to contain a problem or cause a larger, costly incident.

COLUMBUS, Ind.--(BUSINESS WIRE)-- Cummins Inc. (NYSE: CMI) today announced that its Power Generation business has been selected to supply battery energy storage systems (BESS) for a large U.S. data center project, supporting utility-defined requirements for managing AI-driven load fluctuations, mitigating load oscillations and enhancing ride-through performance.

This announcement marks a significant milestone for Cummins’ BESS business as this project would be the company’s largest BESS deployment to date. It also reflects Cummins’ continued role in supporting the North American data center market with reliable, sustainable power solutions.

“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. “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. This project reinforces our commitment to helping customers build reliable, resilient and increasingly sustainable power infrastructure.”

The BESS solution adds another layer of capability to the project’s power architecture. The system is designed to help meet utility-defined requirements for managing AI-driven load fluctuations, mitigating load oscillations, and supporting ride-through performance. It can rapidly charge or discharge to reduce demand spikes, improve power quality and maintain a more stable load profile at the utility interconnection point.

Launched in May 2025, Cummins BESS solutions reflect the company’s commitment to innovation and evolving with the needs of its customers.

For data center developers, BESS is emerging as a strategic power enabler. As grid constraints intensify, interconnection queues grow longer and energy costs increase, BESS can help accelerate deployment timelines, enhance resilience and optimize available power capacity.

Cummins offers a flexible, utility-scale BESS solution designed to support near-term power availability and long-term energy resilience strategies. Whether deployed as a bridge-to-grid solution, integrated with backup power systems or incorporated into a broader microgrid architecture, Cummins BESS can help customers maximize available grid capacity, manage peak demand and meet utility-defined load-management requirements by smoothing rapid fluctuations in AI-driven power demand.

Key specifications of Cummins BESS for data center and AI campus applications include:

• Designed specifically for hyperscale workloads, ensuring resilient operation
• Flexible DC block architecture compatible with multiple PCS and EMS ecosystems
• Bridge-to-grid ready and designed for integration with diesel and natural gas generators
• 5MWh nominal capacity
• Lithium iron phosphate (LFP) battery chemistry
• Liquid cooling thermal management
• UL 9540A, UL 9540, UL 1973, NFPA 855, NFPA 68, IEEE 1547 and UL 1741 SA/SB

Backed by more than 100 years of Cummins power generation expertise, Cummins BESS solutions are more than energy storage assets. They are tools that enable developers to build resilient energy ecosystems that support faster deployment and reliable operation of hyperscale and AI-driven data center campuses.

“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,” Bush 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.”
