Science Friday

Maine nearly became the first state to ban data centers

25 Apr 2026

Transcription

Chapter 1: What are the main concerns surrounding data centers in Maine?

3.271 - 26.986 Flora Lichtman

Hey there, this is Flora Lichtman and you're listening to Science Friday. Data centers have been a hot topic in Maine this week. These centers, which are increasingly needed to support the AI industry, are controversial. They use a lot of power and water and they can drive up electricity costs. The state's House and Senate passed an 18-month moratorium on data center construction.

27.386 - 40.027 Flora Lichtman

It would have been the first statewide ban. But Maine's Governor Janet Mills vetoed the plan, citing concerns about jobs. Here to break it all down is Pete McGuire, climate reporter at Maine Public Radio. Thanks for being here.

40.368 - 41.269 Pete McGuire

Glad to be here. Thank you.

41.69 - 47.419 Flora Lichtman

OK, so what were the details of this data center ban that that was passed by Maine's legislature?

0

47.686 - 69.007 Pete McGuire

So what they had proposed was an 18-month pause on all data center construction above 20 megawatts and the development of this coordinating council full of experts and government officials and utilities and other interested parties that would kind of come up with rules of the road and regulations for developing these facilities in the future.

69.787 - 73.491 Flora Lichtman

So Maine's governor vetoed this. Do we know why? Yeah.

73.741 - 100.653 Pete McGuire

One of the main sticking points for the governor was this project in Jay that it's a town really near her hometown. You know, it's a place that she knows really well. And local officials there were kind of embracing this $550 million project that would bring in jobs and some economic development and rehabilitate people. or reused rather, an old paper mill that closed down a few years ago.

Chapter 2: What was the proposed legislation regarding data centers in Maine?

101.554 - 120.956 Pete McGuire

This is an area that's kind of been economically struggling since then. That was a big blow to the economy in the region. And people see this as a way to inject some money, some tax revenue, and potentially some jobs into the area. The governor found this to be a really sticking point. She asked for an exemption to the bill for this project specifically that didn't make it.

121.317 - 124.2 Pete McGuire

And that was a big part of her decision making, I would imagine.

0

124.18 - 125.962 Flora Lichtman

how did the legislation originate?

0

126.623 - 135.354 Pete McGuire

It originated with this council firstly, and then it kind of morphed into a moratorium. Data centers have not been an issue in Maine.

0

Chapter 3: Why did Maine's Governor veto the data center ban?

135.634 - 151.133 Pete McGuire

It just happened maybe in the last six months that these projects started popping up. And legislators kind of thought, well, even though electricity is really expensive in Maine, we have a cooler climate. Some people say that's really good for data centers. It saves on cooling costs and things like that.

0

151.754 - 170.016 Pete McGuire

But let's get ahead of this because we've seen what's happened in the rest of the country and we've seen how upset people are getting about this and how data centers can influence increasing electric bills and the environmental concerns you mentioned about them. So let's get ahead of this. Make sure they're done properly when they come here.

0

170.806 - 179.314 Flora Lichtman

So it originated with this council, but what about Mainers themselves? Has there been vocal opposition from the citizens of Maine?

0

180.323 - 187.392 Pete McGuire

Yeah, in two cases. In one case, this development came forward as kind of a fully-fledged package with a tax break.

0

Chapter 4: What local economic factors influenced the data center ban decision?

188.012 - 207.917 Pete McGuire

This was in the city of Lewiston. And it kind of got plunked on the desk of the city council. And people were really, really upset. And there was almost immediate backlash. And the city council immediately voted unanimously to cancel that project. Another one in a smaller coastal town. People didn't know about it until...

0

207.897 - 221.228 Pete McGuire

They found out through some filings that the town council was doing about this. So people feel like these are being developed in secret. They don't know about them until it's too late. And that has really increased opposition to data centers in the state.

0

222.15 - 223.934 Flora Lichtman

Is there opposition to this ban?

0
0

225.143 - 240.439 Pete McGuire

There is. Most Republicans in the state legislature voted against this with the idea, the argument being Maine has enough regulations. There are ways that we could regulate these facilities without having a moratorium. We don't need this council to make new rules specific to these.

241.079 - 253.412 Pete McGuire

And because there are places in the state that could maybe benefit from smaller data centers, places that need some economic development, could do with the tax base and whatever, you know, small jobs might be brought there.

253.578 - 256.905 Flora Lichtman

Why do you think Maine is out front on this?

257.105 - 275.104 Pete McGuire

I think, like I said before, part of it has to do with the fact that we're last. This hasn't been a boom, you know? I mean, this hasn't been boom times like it has been in Northern Virginia, Texas, Oregon, Arizona, places like that, you know, where this has been going on for years and now we're kind of seeing the backlash.

275.505 - 284.074 Pete McGuire

I think people who are in favor of this moratorium are saying, we have a chance here to get out in front of this and not end up like places where this has gone wrong.
