Regulatory Environment Score

Maine's regulatory environment is characterized by a high volume of both moratorium enactments and rejections, with at least 68 moratoriums enacted but also at least 66 rejected, indicating an intensely contested regulatory landscape where outcomes vary widely by jurisdiction. Zoning results are unfavorable, with at least 1 approval against 3 denials, and at least 4 projects have been blocked with only 2 approved despite opposition. Unlike neighboring New Hampshire, where moratorium proposals have largely not been enacted, Maine has seen moratoriums both succeed and fail at comparable rates, creating significant uncertainty for developers. The 33 active companies suggest moderate market interest, potentially driven by the state's cool climate and potential for renewable energy, but the permitting environment remains difficult to navigate.
