  • Legal Authority

    Maine enacted the Act to Support Solar Energy Development in Maine during its 2014 legislative session. 4   Section 1 of the Act states that it is “in the public interest to develop renewable energy resources, including solar energy, in a manner that protects and improves the health and well-being of the citizens and natural environment of the State while also providing economic benefits to communities, ratepayers and the overall economy of the State.” 5 Section 2 of the Act instructs the Public Utilities Commission to determine the value of distributed solar energy generation in the State, including “the value of the reduced environmental impacts of the energy.” 6
