Maine Legislature Advances Bill to Temporarily Ban Large AI Data Centers

Generative AI has sharply increased demand for computing power and data-center electricity, putting greater pressure on local grid capacity and household power prices. Maine lawmakers are therefore considering curbs on the expansion of large facilities to prevent corporate electricity demand from crowding out residential and commercial users. The technology industry, however, worries that a ban would weaken the state’s ability to attract AI investment and infrastructure.

The Maine Legislature recently gave preliminary approval to a bill that would suspend construction of large data centers requiring more than 20 MW of power until November 2027. The measure must still complete the remaining legislative process. Its central aim is to pause development while the state assesses the effects on grid capacity and electricity prices. If ultimately enacted, Maine would become the first US state to adopt such a construction ban.
