In lieu of statewide regulations, a growing number of Illinois cities and counties are telling data centers to come back later or adhere to new regulations.
In Aurora, what began as a 180-day moratorium ended with city officials bringing the regulatory hammer down on data centers after many community members complained about excessive noise, utility bills and environmental concerns stemming from the city’s existing facilities.
Nine months removed from the September moratorium, Aurora’s data centers are having to play by new rules. Restrictions on where facilities can be built and updates to zoning rules to give the city approval power over new developments. Strict noise emission, water efficiency and energy efficiency standards for new data centers. Mandatory annual reporting of energy use, water use, noise levels and the storage of biometric data for all data centers, including those already built.
“My administration is about putting people and planet first, so it’s making sure that the lights always get turned on for residents of Aurora, instead of seeing the power stripped away for data centers,” Aurora Mayor John Laesch said. “It’s good news that other municipalities and counties are taking action on this.”
So far, at least six counties and nine cities in Illinois have approved data center moratoriums or regulations. Since May, Bloomington, Normal, Effingham, Bourbonnais, Carbondale, Logan County and Lake County have implemented data center moratoriums ranging from a six-month ban to a whole year. McLean County took a stronger approach in June, requiring existing data centers to document their electrical consumption and mandating data center proposals to identify potential impacts on local infrastructure, emergency services and utilities.
Much of the blowback against data centers stems from concerns about the facilities’ energy and water use amid rising utility costs.
Without regulations in place, advocates and local officials worry data centers will strain the electrical grid and deplete Lake Michigan and rural well water faster than rain, runoff and groundwater can replenish them. Data centers already account for 5.4% of Illinois’ electrical consumption and that demand is expected to balloon by 133% by 2030, according to the U.S. arm of the International Energy Agency. At the same time, electric costs for ComEd customers in June have jumped 12%, while prices for Ameren customers downstate rose by nearly 30%, according to the Citizens Utility Board, a utility consumer watchdog group.
