Illinois Power Bills Jump 50% Due to Data Center Growth

Illinois has emerged as a significant hub for data centers, with over 115 live facilities and dozens more planned. This growth has led to a dramatic increase in electricity and water consumption, with server farms requiring millions of gallons of water daily for cooling and huge megawatts for AI and cloud tasks. Experts indicate that future demand forecasts from PJM, which operates the power market in northern Illinois, were largely driven by proposed data centers. This surge in demand has directly impacted consumers. ComEd supply prices increased by approximately 50% on June 1st, 2025, pushing up capacity prices that are reflected in electric bills. Families in Joliet, for instance, have reported summer bills soaring to over $500. Consumer groups have expressed concerns that customers are already paying for power capacity that may not be fully utilized. In response, Illinois lawmakers have introduced the POWER Act, aimed at compelling data centers to disclose their water and energy usage and to supply renewable power. Polling data suggests strong support for the POWER Act among Illinois voters, and Governor Pritzker has joined a bipartisan effort to enact these protections.
