T5 Data Centers is looking to develop multiple gigawatt-scale campuses, starting with a site outside Chicago, Illinois.
“We’re thrilled to announce our scaled campus in Grayslake, IL,” the company announced on LinkedIn over the weekend. “The Grayslake scaled campus marks a key milestone in our vision to build five 1GW scaled data center campuses designed to meet customer demand and fuel long-term growth with reliable, sustainable solutions.”
T5 said the site will support 20 buildings, each offering 60MW, for a total of 1.2GW. Occupancy for the first phase is set to start in 2027.
Grayslake is located 40 miles north of Chicago. T5 first announced plans for a Grayslake campus in May 2024; at the time the 160-acre site was set to span 480MW, with the first building slated to come online in Q4 2027, offering 60MW of IT capacity.
It’s unclear if T5 has expanded the scope of its previously announced Grayslake site or if this is a separate development.
DCD has reached out for more information, as well as details on the other gigawatt-scale developments.
On its website, the company lists T5@Chicago IV in Grayslake; the listing says the 140-acre site is set to offer 540MW across 2 million sq ft, with a 2028 phase 1 delivery. The listing suggests the first phase will offer 30MW across 100,000 sq ft.
T5 already operates a data center site in the Chicago area at Elk Grove, and is planning a 36MW facility at nearby Northlake.
