States push back on data centers as AI infrastructure spreads nationwide

Anti-data center legislation is gaining momentum across the United States at both state and local levels, driven by public concerns over the rapid expansion of AI infrastructure. Key issues include rising consumer electricity bills, the need for extensive grid improvements to support data centers, and environmental impacts such as noise and air pollution from backup gas turbines. Communities also express general reluctance about the large physical footprint of these facilities. Maine has become a focal point, with its legislature passing a bill last week that would impose an 18-month ban on large-scale data centers (those over 20 megawatts). However, Governor Janet Mills has not yet signed the bill, and her decision is uncertain, partly due to the legislature not approving an exemption she sought for a specific data center site. This legislative action in Maine is being closely watched as a potential precedent for other states, with nearly a dozen states currently considering similar measures. Additionally, a Wisconsin city recently approved a referendum allowing voters more influence over major tax-funded projects, directly responding to a nearby data center campus. While federal-level legislation, such as a moratorium bill proposed by Senator Bernie Sanders and Representative Alexandria Ocasio-Cortez, has gained less traction, federal discussions are addressing niche issues like ensuring data centers cover the costs of electricity increases for consumers. In response to growing resistance, AI companies like Microsoft and OpenAI have made pledges to be community-minded and contribute to their own power infrastructure, including signing a White House-backed commitment. The ongoing "data center battle" will likely see continued legislative efforts at state and local levels, with a close eye on public opinion and how these issues impact upcoming elections.
