Why It Matters
L.D. 307 represented the first statewide attempt in the U.S. to impose a moratorium on data center construction. The bill also proposed creating a 13-person council to study and recommend policies on data center development. Public opposition to data centers has been rising across the country due to concerns about environmental impact and electricity rate increases.
Maine Governor Janet Mills has vetoed a bill that would have temporarily brought permits for new data centers to a halt. If it had become law, L.D. 307 would have imposed the country's first statewide moratorium on new data centers — lasting, in this case, until November 1, 2027. The bill also called for the creation of a 13-person council to study and make recommendations on data center construction. With public opposition to data centers rising, other states including New York have considered similar moratoriums. In a letter to the state legislature, Mills — a Democrat currently running for the U.S. Senate — said that pausing new data centers would be "appropriate given the impacts of massive data centers in other states on the environment and on electricity rates" and that she "would have signed this bill" if it had included an exemption for a data center project in the Town of Jay. That project, Mills said, "enjoys strong local support from its host community and region."
