Illinois Halts Data Center Incentives Amid Water, Energy, and Local Backlash
A moratorium on state tax breaks and new environmental restrictions signal a dramatic shift for Illinois’ booming data center industry
INCENTIVE: Gov. JB Pritzker announced that incentives for data centers will be paused for two years. Here's how that will impact business for contractors buoyed by the budding industry.
Illinois, once a national leader in attracting data centers with generous tax breaks and abundant power, is now at the center of a fierce debate over water, energy, and the future of its digital economy. In February at his annual State of the State address, Governor J.B. Pritzker announced a two-year suspension of state tax incentives for new data centers, a dramatic policy shift that has sent shockwaves through both the tech industry and local governments.
Likewise, a new bill seeks to ban data centers atop the Mahomet Aquifer. The “Data Center Water Transparency and Aquifer Protection Act” would begin on January 1, 2027. And in the state capital, Sangamon County voted last week against a proposed moratorium on new data centers, clearing the way for a controversial $500 million CyrusOne project. The State Journal-Register, however, described the meeting as contentious, with board members split over whether the benefits outweigh the burdens.
For years, Illinois’ policy of waiving sales taxes on equipment and construction materials fueled a boom in data center construction, especially in the northern collar counties. But as the industry has begun to eye expansion further south, the fragility of the southernly grid and the cost of electricity have become flashpoints.
Tony Adolfs, executive vice president of SMACNA Greater Chicago, which represents union sheet metal contractors, described the surge in data center work across Illinois but noted the growing uncertainty. “This is the data center highway. And cutting back on incentives, obviously that’s going to impact the data center work moving forward,” Adolfs said, but he noted that much of megaproject and data center work for Greater Chicago contractors has already naturally moved out into neighboring states.
“A lot of our contractors are doing work more outside of our immediate area, more than they typically have,” Adolfs added.
As lawmakers in Springfield wrangle over the future of Illinois’ data center industry, the stakes are high for local economies, labor unions, and global tech giants alike. The two-year pause on incentives gives the state time to reassess, but also introduces new uncertainty in a sector that has, until now, only grown.
