The power behind Maine's data centers

EIA-860M lists 274 operating power plants in Maine totalling 6,164 MW of nameplate capacity, of which 5 are natural gas plants. That is the supply these 3 facilities draw on. None of these data-centre records states a load, so this page draws no line between the two — it only puts them in one place.

Data centers in Maine: FAQ

How many data centers are in Maine?
3 are on the public record this directory reads: 0 in county or city permit GIS and 3 in OpenStreetMap. Maine has no state register of data centres, so that is a lower bound rather than a count.
Where are the data centers in Maine?
Mostly around Brunswick, which holds more of these records than anywhere else in the state. The map above plots all 3 and the city table breaks them out.
Is there a data center near me in Maine?
The city table below groups every facility on record by city, which is the quickest way to find the data center closest to a given town. This site does not read your location.
Are these AI data centers?
Unknown, and no public record in Maine says. A permit records a data center; it does not record the tenant or the workload. Where an AI data center exists in Maine it is in this list without being labelled as one, and this page will not guess which.
Who operates Maine data centers?
FirstLight appears against more of these records than any other operator. Where a source names no operator the row says so rather than guessing one.
How many Maine data centers are under construction or planned?
No source covering Maine publishes a build status, so this page shows none. Status is only available where a county publishes its permit layer.
How current is this, and what is left out?
OpenStreetMap extract 2026-09-17; county permit capture 2026-09-12. Power draw, tenant, commissioned megawatts and lease terms are not in any of these public records and are not shown anywhere on this site.
