Maine moves to ban major new data centers, citing strained grid and soaring power bills

The moratorium

Maine’s Democratic-controlled legislature has advanced LD 307, a temporary moratorium on new data centers that would need more than 20 megawatts of power. The pause—set to run until November 2027—creates a new Data Center Coordination Council to study how hyperscale facilities might strain the state’s aging grid. Gov. Janet Mills supports the measure, and it has been reported that lawmakers framed the halt as a necessary breathing spell to protect residents from rising electricity costs.

Local fights, stranded projects

The decision follows successful local fights in Wiscasset and Lewiston over water use and safety. Projects now in limbo include proposals for Jay (at an old paper mill site), Sanford and Loring Air Force Base. Rep. Christopher Kessler, according to Maine Public Radio, said “taking this pause now is going to be crucial,” reflecting lawmakers’ worry about capacity. Developer Tony McDonald allegedly called the restrictions “disastrous,” saying his team was “caught in this dragnet” — a reminder that policy can feel like political theater for firms mid-build.

Why it matters beyond Maine

This isn’t just a local zoning spat. It has been reported that data centers now consume roughly 4% of U.S. electricity and could double by 2030 as AI demand balloons. For Mainers already paying some of the nation’s highest rates, that math is not abstract — it’s a wallet hit. Economist Anirban Basu reportedly called Maine a “canary in the coal mine” for state-level resistance to Big Tech’s energy appetite. Will other states follow? If they do, your next cloud backup could come with an extra line on the bill.
