Maine bill proves states are capable of adopting bad data center policies without federal intervention

The Maine House of Representatives has passed House Bill (H.B.) 307, which proposes a statewide moratorium on the approval, development, construction, or operation of new data centers with a load of 20 megawatts or more until November 2027. The bill, which passed largely along party lines, is now expected to move to the Senate for approval and then to Democratic Gov. Janet Mills for her signature, potentially making Maine the first state to institute such a ban. The legislation, introduced by State Rep. Melanie Sachs (D–Freeport), chair of the Energy, Utilities, and Technology Committee, was motivated by concerns over the potential strain data centers place on the power grid and their environmental impacts. The bill also establishes the Maine Data Center Coordination Council, tasked with safeguarding ratepayers, maintaining grid reliability, minimizing environmental effects, and facilitating responsible economic development. However, the proposed moratorium has faced criticism. State Sen. Matt Harrington (R–Stanford) warned that the ban could result in the loss of 100 long-term jobs in his district by halting a previously planned 100–300 megawatt facility. Experts like Neil Chilson of the Abundance Institute suggest that data centers actually provide stable income for utilities, enabling investments in grid upgrades, while Jennifer Huddleston of the Cato Institute argues that environmental concerns are often overstated, and data centers are crucial for existing cloud computing technologies. The article also notes that this state-level action follows a recent proposal by Sen. Bernie Sanders (I–Vt.) for a federal moratorium on AI data centers.
