T5 Data Centers is developing a new data center campus in Grayslake, Illinois.

The 160-acre site, 40 miles north of Chicago, will be used for “multiple data center buildings.”

The first building is set to come online in Q4 2027, offering 60MW of IT capacity.

Eventually, the site could support up to 480MW capacity, and T5 says it will offer customers build-to-suit data center capacity options ranging from powered shell to full turnkey delivery with integration of the company’s construction and operations services.

“The new Grayslake campus represents a major investment by T5 to meet the growing demand for large-scale data center capacity to support cloud and artificial intelligence workloads,” said David Horowitz, senior vice president and head of leasing for T5 Data Centers. “The site’s location is perfectly positioned between major data center hubs of the northern Chicago suburbs and southeastern Wisconsin, which provides an ideal connection point.

“The Chicago land market continues to be one of the premier markets to build and operate data centers because of the attractive tax incentives, labor pool, established connectivity, and power availability.”

Though T5 has not shared the address of the site, it says the land is already zoned for data center use and that an on-site electrical substation will provide “efficient and redundant utility power.”

Horowitz added: “The amount of power at this site, combined with T5’s customer-focused approach to data center development, will greatly benefit our customers.

“T5’s data center business is structured to support our customer’s design, build, and fit out preferences and uniquely allows them to select the operations model that best fits their business requirements now and as they evolve in the future.”

T5 already operates a data center in the Chicago area at Elk Grove, and is planning a 36MW facility at nearby Northlake.

“Our Grayslake campus highlights T5’s vision to provide our customers’ large-scale data center capacity with flexibility and integrated services to meet their requirements,” said Pete Marin, president and CEO of T5 Data Centers.

“Our team’s strong track record of managing the execution and operational risk, strengthens our customer’s confidence that T5 will safely deliver on our commitments to schedule, cost, and performance.”
