Illinois Lawmakers Debate Data Center Regulation Amid Energy Concerns

SPRINGFIELD — Lawmakers in Illinois are intensifying debate over how to regulate the rapid expansion of data centers as concerns grow about rising energy costs, environmental impacts and the state’s economic competitiveness.

Data centers, which store and process massive amounts of digital information — including artificial intelligence workloads — require significant electricity to operate. A state report released in December projects potential energy shortfalls beginning in northern Illinois by 2029 and statewide by 2031, driven in large part by increased power demand from these facilities. In response, Gov. JB Pritzker has proposed a two-year moratorium on state tax incentives for new data centers, saying growth must not undermine affordability or grid stability for Illinois families.

Illinois currently ranks fourth in the nation with 222 data centers. Since bipartisan legislation signed in 2019 created incentives for development, at least 27 facilities have received an estimated $983 million in lifetime tax breaks. Under the governor’s proposal, those incentives would be paused while lawmakers revisit regulatory policies.

Senate Bill 4016, known as the POWER Act, has been introduced to prohibit cost shifting to consumers, require new clean energy capacity for large projects, strengthen water efficiency standards and increase public transparency. Supporters argue data centers should bear the full cost of increased energy demand rather than passing it on to ratepayers. Industry leaders, however, contend that stricter mandates could push investment to other states competing in the artificial intelligence sector.

Another point of tension involves Illinois’ Biometric Information Privacy Act, a 2008 law that restricts the collection and use of biometric data without consent. Industry representatives argue liability risks under the law discourage development, while privacy advocates say the protections are essential.

At the local level, the Aurora City Council recently approved a 180-day moratorium on new data centers as residents raised concerns about noise, water use and rising utility bills. Utilities across Illinois are investing billions in new infrastructure to meet anticipated energy demand, with some requiring long-term financial guarantees from large power users to protect ratepayers if projects do not materialize.

As negotiations continue in Springfield, lawmakers face mounting pressure to balance economic growth with consumer protection, environmental safeguards and long-term grid reliability.
