State-level permits & approvals
Strong home rule tradition; dual-track permitting in organized municipalities. Maine DEP Site Location of Development Act (SLODA): required for developments >20 acres (catches most utility-scale solar); standards address stormwater, groundwater, wildlife, aesthetics. Natural Resources Protection Act (NRPA): separate DEP permit for projects affecting wetlands, significant wildlife habitat, or other protected natural resources. Local zoning: organized municipalities (most of southern/coastal ME) require local permits in addition to state permits — dual track; a moratorium can be imposed even after state permits issued (unique ME vested rights doctrine). Land Use Planning Commission (LUPC): governs ~10.5 million acres of Unorganized Territory (UT) in northern/remote ME (much of Aroostook, Piscataquis, Somerset, Penobscot, Washington, Franklin, Oxford, Hancock counties). DACF Permit: required for solar ≥5 acres on High-Value Agricultural Land (HVAL) — new, eff. April 20, 2025. Aroostook and Washington counties (far NE): outside ISO-NE footprint; served by Versant Power (Emera). Central ME Power (Avangrid) and Versant Power are Maine's two investor-owned utilities.
