Illinois is suspending new tax incentives for data centers amid growing concerns over rising electricity costs, a move that industry observers say could hinder the state’s ability to attract significant investment amid a national surge in artificial intelligence (AI) infrastructure development.
Governor J.B. Pritzker announced the halt on new data center tax breaks effective July 1, 2023. These incentives, established under Illinois’ “Data Center Investment Program,” offered sales tax exemptions to data centers investing at least $250 million, creating 20 jobs and meeting clean energy requirements. Since its inception, the program has granted incentives totaling approximately $983 million to 27 data center projects. In return, the industry generated an estimated $1.85 billion in state and local tax revenue in 2023 alone, according to state reports.
The pause comes amid an infrastructure boom fueled by AI, which market analysts estimate will drive capital expenditures of $5.5 trillion globally through 2030. Data center investment is expected to nearly double from $280 billion in 2026 to $590 billion by 2028, with companies currently finalizing site selections and contracts. Illinois’ decision to freeze new incentives contrasts with aggressive moves by other states: Google’s $40 billion expansion in Texas, Amazon’s $20 billion investment in Pennsylvania, and $25 billion in joint commitments from Amazon and Meta in Indiana underscore increasing competition.
Illinois has some competitive advantages, including access to abundant power—especially from its extensive nuclear fleet—and a skilled workforce. The state has also made efforts to promote high-tech industries, such as the Illinois Quantum and Microelectronics Park on Chicago’s South Side. However, critics argue that halting incentives now risks ceding momentum to states more welcoming to data center development.
The governor’s administration cites concerns over electricity demand and costs. Data centers are energy-intensive, and the regional grid operator PJM Interconnection projects northern Illinois’ peak electricity demand to grow nearly 4% annually over the next decade, more than doubling previous forecasts. Simultaneously, Illinois is pursuing aggressive climate goals, aiming for net-zero emissions by 2045 through acts such as the 2021 Climate and Equitable Jobs Act, which anticipates retiring about 11 gigawatts of traditional generation capacity by 2030 and increasing reliance on variable renewable sources.
Electricity prices in Illinois have risen alongside these changes, with residential rates increasing roughly 20% from 2023 through early 2024—above the national average but comparable to neighboring states. Data center operators have increasingly sought to address such challenges by entering long-term power purchase agreements or financing new power generation capacity themselves; for instance, Meta has contracted to buy electricity from the Clinton nuclear plant in Illinois under a 20-year deal.
Analysts suggest that rather than suspending the program, Illinois could revise incentive terms to require greater contributions from data center developers for power infrastructure and water use reporting. Such adjustments might balance economic development goals with the state’s climate and grid reliability objectives.
Beyond tax benefits and job creation, proponents highlight data centers’ potential to support grid modernization and generate substantial local revenues. Meta’s facility in DeKalb County, Illinois, is expected to yield over $31 million in property taxes in 2025, benefiting local schools. Comparatively, in Loudoun County, Virginia, data centers occupy a relatively small land area but provide a significant portion of local tax revenues, enabling lower property tax rates.
As the competition for AI-related infrastructure intensifies nationwide, Illinois faces a critical decision on how to balance environmental commitments and economic growth. With the window for major capital investments narrowing, stakeholders warn that the state could miss out on a transformative opportunity to secure its role in the burgeoning AI economy.
