United States, the state of Maine adopts a moratorium on new large data centers

The state of Maine has enacted a moratorium on new large data center construction projects, effective until the end of 2027. The measure, adopted by both local legislative chambers, specifically suspends the issuance of permits for data center projects with an electrical capacity exceeding 20 megawatts. This initiative stems from increasing concerns over the substantial energy consumption of data centers, particularly with the rapid growth of generative AI. Studies project that AI-dedicated infrastructures consume 4 to 5 times more power than traditional data centers, potentially driving data centers to represent up to 12% of American electricity consumption by 2030. Maine's decision also follows a rise in its residential electricity rates, with state officials having previously rejected two data center projects in late 2025 over underestimated consumption. Democratic Governor Janet Mills, while generally in favor of the moratorium, had requested an exemption for a $550 million project to redevelop a former paper mill, but the parliamentarians rejected her request. Governor Mills retains the option to veto the text within the next ten days, promulgate it, or allow it to become law without her signature. Maine's action could set a precedent, as a dozen other states, including New York, Georgia, Maryland, Michigan, New Hampshire, Virginia, and Wisconsin, are reportedly considering similar moratoriums.
