Maine Data Center Debate Becomes Major Issue in Senate Race
Data center expansion has become a major issue in Maine’s U.S. Senate race, with rural voters raising concerns about water use, climate impacts, higher utility costs and limited long-term jobs. The Maine Legislature passed a statewide data center moratorium, but Gov. Janet Mills vetoed it, while municipalities have adopted or considered temporary local bans.
Data center development has emerged as a central issue in Maine’s closely watched Senate race between Republican Sen. Susan Collins and Democratic challenger Troy Jackson. Rural voters and researchers cited concerns about resource consumption, rising electricity costs, environmental damage and the limited employment typically created once data center construction ends.
The Maine Legislature passed what would have been the country’s first statewide moratorium on large data centers, but Gov. Janet Mills vetoed the measure. Municipalities across the state have since adopted temporary moratoriums or asked voters to weigh in on expansion. The debate has also fueled significant political spending from technology, artificial intelligence and data center-linked donors, including contributions supporting Collins, while Jackson has called for guardrails and union jobs tied to development.
Collins has supported data centers on a case-by-case basis and helped secure $6.2 million in federal funding for a high-performance computing hub in central Maine. Critics, including policy researchers and local voters, question whether the projects will deliver promised economic benefits and warn that rural communities could bear the infrastructure and utility costs while outside investors capture much of the wealth.
