Yorkville City Council has approved a CyrusOne data center campus development outside of Chicago, Illinois.

The company first announced plans for the campus in June 2024, and received rezoning approval later that month.

The application was filed by C1 Yorkville LLC - a subsidiary of Texas-based CyrusOne - and Yorkville Nexus LLC (aka Green Door Capital) for a data center development spanning 228 acres at Eldamain and Faxon roads.

In total, the campus could have up to nine two-story buildings developed over the next 10 to 20 years and will have an on-site substation.

The proposal was approved on July 9, with Mayor John Purcell saying that the development would have a significant impact on Yorkville.

Along with the development, CyrusOne is paying for road improvements and for the city to bring water and sewer lines to the site. The city will reimburse CyrusOne for the water and sewer infrastructure via tax revenue over time.

CyrusOne and the city will split the cost of moving power poles for road works.

Construction is currently set to begin later this year or in early 2025 and will see the first data center go live in 2026.

CyrusOne currently owns and operates a two-building campus near Yorkville in Aurora at 2905 Diehl Road. Purchased by an affiliate of CyrusOne in 2016, the company recently filed to construct another building at the campus as well as expand nearby to that site.

According to a report from Newmark released last month, data center inventory in the Chicago region has increased by 35 percent over the last five years, but availability is running at just 1.6 percent.

Also developing nearby is Microsoft, having recently purchased 500 acres in Plano, Illinois.
