Mills Vetoed the Data Center Ban to Save Jay's Project. It's on Hold Anyway.

Maine's Legislature passed the first state-level pause on data center construction anywhere in the country this spring, and Gov. Janet Mills vetoed it. The reason she gave, in large part, was a single redevelopment project at the old paper mill in Jay. That project is now on hold, because its developer walked away. Meanwhile Westbrook and Gorham are moving to write their own bans, and Augusta's answer is a study council. We think that's backwards. Maine needs one statewide rulebook on where data centers can go and what they're allowed to draw from the power grid and the water supply — not a veto built around saving one deal, and a town-by-town scramble to fill the gap it left behind.

Lawmakers began weighing a moratorium on Feb. 16, 2026, as Maine Public reported, amid a wave of proposed AI-scale server farms and the power and water demands that come with them. By April 15, Maine had become the first state in the country to pass a law blocking new data center construction, as capacityglobal.com reported, and by April 21 that first-in-the-nation bill was sitting on the governor's desk awaiting her signature, as Maine Beacon reported. She didn't sign it. On April 24 she vetoed it, as the Center Square reported, and paired that veto with support for a $550 million redevelopment plan at the Jay mill, as Mainebiz reported. On April 29, the Legislature tried and failed to override her, sustaining the veto, as the Portland Press Herald reported.

The Jay fight was the hinge the whole debate turned on. The moratorium's fate and the mill project's fate were treated as the same question heading into a House vote, as newscentermaine.com reported, and the governor made her position explicit, backing an exemption for the Jay project from the statewide pause, as newscentermaine.com also reported. That's what Mills spent her veto on: one mill town's jobs, weighed against a statewide check on an entire industry.

Here's the part that should bother anyone who backed the veto for Jay's sake. The project it was built to save isn't happening, at least not now. The data center proposed for the former Jay paper mill was put on hold after its developer backed out, as WMTW reported. Maine gave up its one shot at a statewide pause, kept the moratorium off the books for the whole industry, and the specific project cited as the reason for that veto is stalled anyway. We don't think that makes the veto wrong on its own — deals fall apart for reasons no governor controls — but it does mean the tradeoff Maine actually made looks worse than advertised: no statewide rule, and for now, no Jay mill jobs to show for it either.

With Augusta unwilling to set one standard, towns are doing it themselves. Westbrook is moving to seek its own temporary ban on data centers, as Mainebiz reported, and Gorham officials are weighing a permanent one, as WGME reported. The state's own response so far is a data center council formed to address development concerns, as Mainebiz also reported — a body for discussion, not a rule anyone has to follow. That's how a state ends up with a data center welcome in one town, banned next door, and governed nowhere by a consistent standard for how much grid power or water it can draw before it has to answer for it.

The strongest case against a statewide pause is the one Mills effectively made: a blanket moratorium doesn't distinguish between a speculative server farm and a project tied to real jobs in a mill town that has already lost too many of them, and a one-size ban risks strangling the good deal along with the bad ones. That's a fair point, and it's the honest case against a blunt-tool moratorium. But the answer to a blunt tool is a sharper one, not a veto and a shrug. A statewide framework with real siting standards, and clear rules on power and water costs, could have carved out exactly the kind of mill-town redevelopment Jay needed without leaving every other town in Maine to pass its own patchwork ban to get the same protection. Maine didn't have to choose between the Jay deal and a statewide rule. As it stands, it has ended up with neither.

A council can study data centers for another year while more towns pass their own bans and developers decide Maine's rules are whatever the nearest select board says this month. We think that's the real cost of this veto: not that Mills chose to protect a project in a mill town that needed one, but that Maine still doesn't have one rulebook on siting, power draw, or water costs — and every month without one, the patchwork gets a little more permanent, town by town.
