Maine Hits Pause on Big Data Centers—But Jay's Mill Project Could Get an Exception

Maine just passed new rules that stop most large data centers from being built for the next year and a half. But there's a catch: a $550 million plan to turn a closed paper mill in Jay, Maine into a data center may be exempt from those rules. Local officials in Jay support the project, and the governor has hinted she may let it proceed anyway.

The Androscoggin Mill in Jay once gave jobs to about 1,500 people. It closed years ago, leaving a big hole in the local economy. Now a company called JGT2 Redevelopment wants to convert the mill into a data center, and Jay's town board has backed the idea.

What Maine's New Data Center Rules Say

In April 2024, Maine lawmakers approved a pause on building large data centers. The rule applies to any facility that uses more than 20 megawatts of electricity—roughly the power needed to run about 20,000 homes. The ban lasts until November 1, 2027.

The state created a new committee to study whether data centers should be allowed in Maine at all. The committee will look at three main questions: Will these facilities strain the electrical grid? Will they raise power bills for regular households? And what happens to the environment?

Governor Mills has said publicly that she thinks the Jay project should be allowed even with the new rules, but nobody has explained exactly how that would happen yet.

Why Jay Needs This Project

The Androscoggin Mill closed for good in 2008. Since then, Maine's logging and paper industries have shrunk, eliminating hundreds of jobs. In 2020, two paper mills shut down and laid off 134 workers. The town of Jay lost a major source of tax money and stable employment.

In 2023, Maine lawmakers even voted to give Jay money to help replace the taxes the mill used to pay. That shows how much the closure hurt the community.

Now the Jay Select Board sees the data center project as a way to bring money back to town. The project would pump $550 million into the local economy.

How Data Centers Work (And Why They Matter)

A data center is a large building filled with computer servers that store and process information for the internet. Think of it like a digital library where trillions of books are stored and found instantly when someone asks for them.

Data centers need enormous amounts of electricity because the servers run 24 hours a day, 7 days a week—unlike a factory that might shut down at night or on weekends. A facility of this size would likely need 50 to 100 megawatts of continuous power, or enough electricity for 50,000 to 100,000 homes.

The old mill site has some advantages. The building already has the electrical connections and industrial setup that a data center needs. It also sits below a pond that could provide water for cooling the servers, though the state would need to approve that.

The Jobs Question

Here is where the economics get tricky. The old Androscoggin Mill employed 1,500 workers. A modern data center of similar size would hire only 20 to 50 permanent staff.

That doesn't mean the project creates no jobs—there would be construction work to build it, and those jobs pay well. But once it's built, the steady paychecks and career opportunities that the mill once provided would not come back.

The real benefit for Jay is property tax revenue. Data centers are expensive to build, so the town would collect significant taxes on the equipment inside. That money could ease the town's budget problems without requiring new homes and schools the way other types of development would.

Why Maine Wants to Slow Down Data Centers

Data centers use electricity constantly. A paper mill or factory might use lots of power during the day but less at night. Data centers never stop. This steady, heavy demand can overload the electrical grid and push up power bills for everyone in the region.

Other states have learned this lesson the hard way. They welcomed data centers without thinking through the impact on power supplies. Then ratepayers complained when their bills went up. Maine is trying to plan ahead instead of rushing into it.

The state's new committee will spend the next 18 months studying whether Maine has enough electricity to handle more data centers, and at what cost to residents.

What This Means for Jay and Other Towns

The Jay data center proposal sits at the center of a real tension in rural America. Towns that lost manufacturing jobs need money and employment. Data centers offer that, at least on the tax side. But the power grid impact worries state officials.

The outcome of the Jay case will likely influence other communities in Maine and New England that have closed mills and factories. If Jay gets its exemption, other towns may push for their own data center projects. If the state denies it, those towns will have to find other ways to recover economically.

Maine's approach here is worth watching. The state is trying to avoid repeating what happened elsewhere—allowing too much growth too fast, then scrambling to manage the consequences. Whether state officials can balance the urgent needs of rural communities with the long-term health of the power grid remains to be seen.
