CHICAGO—Ascent Corp. is partnering with Sterling Bay Cos. to build a $200 million data center on South Desplaines Street.

Ascent announced today plans to build the CH3 Data Center. Ascent says its center will offer up to 50 MW of power, providing users purpose-built space delivered in flexible and scalable data center suites. The developer will feature build-to-suit infrastructure for companies seeking to build or lease wholesale data center space in a downtown location. The development will accommodate a wide range of design architectures empowering tenants to build out the power density, redundancy and efficiency levels they require as well as benefit from low latency and Ascent’s onsite operational services.

“CH3 is incredibly flexible, unlike the standard multi-story data centers in Chicago, making it adaptable to new technology and server rack designs that some of the older constructions are unable to accommodate,” says Phil Horstmann, CEO of Ascent, in a statement. “Downtown Chicago is an attractive location for data center space, but previously didn’t offer the options the market is now demanding. We're talking with companies about their current data center needs and developing CH3 to meet those market demands.”

Sterling Bay owns the West Loop property. The development marks Ascent’s third data center in the Chicago area, following the purpose-built single tenant Northlake project and CH2 also in Northlake, Ill. which is now underway with three enterprise tenants.
