The story so far

Maine at a glance

The largest footprint in Maine belongs to Prime Data Centers, behind 1 tracked facility. Many of these sites are filed under shell or project names rather than the parent's — our operator column resolves them back to the real corporate parent wherever the chain is documented.

Geographically, the buildout clusters: Cumberland County leads Maine with 2 facilities and a composite risk score of 6/100. Androscoggin County and Lincoln County follow. Our county risk score weights project exposure (40%), power demand (30%), water draw (15%), and land footprint (15%); the full breakdown is shown on each county page.

Maine is not done growing. 2 facilities are in the pipeline — proposed, permitted, or under construction — which is where residents still have a say at zoning hearings and in rate cases. Each pending project is a decision about land, water, electricity prices, and tax revenue that hasn't been finalized.

We also surface the accountability trail: 3 state bills mentioning data centers and 6 recent news items are tracked for Maine below, pulled from LegiScan and GDELT and refreshed automatically. Legislation is linked to the counties and operators it names; news is classified by community sentiment.

Data-center policy watch: Maine's legislature passed a statewide data-center moratorium (LD 307) in 2026, but the governor vetoed it.

Methodology & sources

Facility counts include operating, under-construction, proposed, and permitted sites. Capacity (MW) combines operator disclosures, interconnection-queue estimates, and research datasets; see each facility for provenance. County risk scores weight project exposure (40%), power demand (30%), water draw (15%), and land footprint (15%), renormalized over measured factors.

Every row carries a confidence level (high / medium / low) and a source URL. Spot an error? Tell us.
