Compass Starts on Data Center at Former Sears HQ Site

ComEd and Compass Datacenters have formally launched a massive Illinois data center project. The new data center campus will be located at the former Sears Headquarters campus, transforming the site into a new data center campus projected to bring $10 billion of investment into the area in the coming years.

The new Compass site represents the Dallas-based company’s first data center campus in Illinois, bringing five hyperscale, or high-capacity and scalable facilities, onto the nearly 200-acre site. ComEd is delivering infrastructure upgrades for this project, including a new onsite substation that will be energized in mid-2026 to power the site. The planned Compass site is slated to be one of the largest data centers in Illinois and will create approximately 1,000 jobs during a multi-year construction effort kicking off this year.

“Compass Datacenters will inject new economic life into the former Sears site, and our region’s unparalleled infrastructure will ensure the company can thrive well into the future,” said Gil C. Quiniones, President and CEO of ComEd.
