Switch Data Centers and Schneider Electric have agreed an expanded $1.9 billion contract that they say is North America’s largest-ever data center cooling deal.

The supply capacity agreement (SCA) between the two firms will see Schneider supply prefabricated power modules for Switch’s data centers, as well as its Uniflair chillers. It will be the first time the chillers have been deployed in the US.

By integrating advanced cooling and power technologies into Switch’s hyperscale data center designs and existing hybrid air and liquid cooling systems, the companies believe they are “laying the foundation for more resilient, scalable and future-ready infrastructure.”

The SCA contract is designed to provide guaranteed capacity to the end user, in this case Switch, while also allowing some flexibility for how this is delivered. The companies say this is useful in the rapidly evolving AI infrastructure market.

“As AI continues to reshape the digital landscape, we see an opportunity not just to meet demand, but to define what the next generation of data centers can achieve,” said Vandana Singh, SVP of secure power for North America at Schneider Electric. “By combining modular power, advanced cooling technologies, and a long-term service model, we’re helping create infrastructure that anticipates the future of AI workloads, making energy smarter, more adaptable, and more sustainable.”

Uniflair chillers use oil-free, variable-speed centrifugal compressors and integrated free cooling to match capacity to real-time IT load, preventing overcooling and reducing run hours.

The prefabricated power modules come with standardized, pre-tested layouts that optimize airflow and containment to increase economizer hours and reduce cooling energy compared with traditional builds.

The agreement is the largest cooling service engagement Schneider Electric has ever undertaken.

“Expanding our relationship with Schneider Electric advances that mission as we pioneer a new class of AI-ready infrastructure, designed for operational insight, extreme efficiency, and the flexibility to evolve as technology advances to meet the growing demand of our customers,” said Jason Hoffman, chief strategy officer at Switch.

Founded in 2000, Switch operates its large 'Prime' data center campuses in Austin, Texas; Reno and Las Vegas, Nevada; Grand Rapids, Michigan; and Atlanta, Georgia. Over the last year, it has filed to expand further in Austin and Atlanta.

In July, it announced it was developing smaller, denser data centers specifically for AI workloads.

Its Core Campus, located in Las Vegas, Nevada, will have up to 495MW of power upon full build-out.

Switch's traditional proprietary designs feature hot-aisle containment, but the company has now developed a liquid cooling offering too, and is hosting an Nvidia GB300 NVL72 deployment on behalf of AI cloud provider CoreWeave.

The contract was announced as part of Schneider Electric's North America Innovation Summit 2025, taking place this week in Las Vegas.
