Mansfield, Massachusetts, becomes first town in state to ban large data centers

The town of Mansfield, Massachusetts, has made headlines as the first municipality in the Bay State to implement a zoning bylaw that effectively bans data centers with high electrical demands. The bylaw, overwhelmingly approved by residents at a recent Town Meeting, restricts data centers to a maximum power usage of two megawatts. Mark Corsillo, who spearheaded the bylaw as a Planning Board member and was recently elected to the town's Select Board, noted that anything more powerful would likely force the town-owned electrical department to purchase additional capacity, risking cost increases for ratepayers.

The decision in Mansfield has drawn attention from planners across Massachusetts and residents in other states like Georgia and Ohio, who are seeking to understand the bylaw's novel approach to limiting data center development based on power consumption. The move comes amid a rapid expansion of artificial intelligence and cloud computing, which has led to increased caution among planners nationwide regarding the facilities' resource intensity.

The article also provides broader context, mentioning Maine Governor Janet Mills' recent veto of a state moratorium on data center construction due to concerns about job creation, and a lawsuit filed by Lowell residents against Markley Group and the Massachusetts Department of Environmental Protection over a data center's impact. These examples highlight the growing national debate around data center impacts on water security, electrical capacity, and community character, concerns also echoed by Mansfield residents.
