Gate News message, April 15 — Maine’s legislature passed a bill on April 14 to temporarily halt construction of large data centers, potentially making it the first U.S. state to pause approval of new large-scale data center projects. The bill passed the state House of Representatives with 79 votes in favor and 62 against, and later cleared the Senate with 21 votes in favor and 13 against. It still requires the signature of Democratic Governor Janet Mills to become law.
The bill mandates a moratorium through October 2027 on approving new data center projects with an electrical load exceeding 20 megawatts. During this period, an advisory committee will assess the impact of data centers on the local power grid, residents’ electricity bills, and the environment.
State Representative Melanie Sachs, who introduced the bill, said the timeframe would allow Maine’s energy and environmental regulators to establish industry oversight rules for large data center construction.
