Mills Vetoes Data Center Moratorium, Citing Economic Stakes and Policy Gaps

Maine Governor Janet Mills has vetoed L.D. 307, a bill that sought to impose a statewide moratorium on the construction of data centers exceeding 20 megawatts of electricity usage. The legislation aimed to temporarily halt new data center development until late 2027, allowing a state commission to study the potential impacts of rapid data infrastructure expansion on Maine's electric grid, natural resources, and utility rates. Governor Mills' decision preserves the path for a significant data center project in Jay and has reignited a broader debate within the state. Proponents of the moratorium argued it was crucial to assess how facilities, driven by artificial intelligence and cloud computing, would affect the state's energy consumption and costs for ratepayers. The veto underscores a tension between economic opportunities presented by the burgeoning AI economy and growing concerns about the environmental footprint and infrastructural strain posed by large-scale data centers in Maine.
