FAQs
Why is Aurora part of the Chicago data center market?
Aurora sits 35 miles west of downtown Chicago on the I-88 Technology Corridor, where dedicated fiber routes connect suburban data centers to the Chicago Board of Trade, CME Group, and CBOE exchanges with latency budgets under 5 milliseconds. ComEd's pre-built large-load substation infrastructure along the corridor enables data center campus feeds of 50–200 MW without the custom utility construction required in less-developed markets. T5, CyrusOne, and Digital Realty have all invested in Aurora/Naperville campuses.
What Illinois data center tax incentives are available for Aurora projects?
Illinois SB 3616 created a state-wide data center investment tax credit (25% of qualified investment over $250 million) and sales tax exemption on qualifying data center equipment. Smaller projects may qualify for the Illinois Enterprise Zone sales tax exemption in certain geographies.
