How much electricity do Maine's data centers use?

We don’t publish a state total, and the reason matters: nearly all facilities here never disclose a capacity, so any sum would look like a census of Maine's data center load while leaving out the sites that stayed quiet. Each facility page shows the figure its own source states. A single large campus can draw as much power as a small city.

Are Maine data centers near protected land?

6 of the tracked facilities in Maine sit within 10 miles of protected public land, measured to the real boundary of the nearest national park, wilderness area, wildlife refuge or conservation area; none sit within a single mile.
