Value of Solar Study

During its 2014 session, the Maine Legislature enacted an Act to Support Solar Energy Development in Maine. P.L Chapter 562 (April 24, 2014) (codified at 35‐A M.R.S. §§ 3471‐3473) (“Act”). Section 2 of the Act required the Public Utilities Commission (Commission) to determine the value of distributed solar energy generation in the State, evaluate implementation options, and to deliver a report to the Legislature.


For the project, the Commission developed the value of solar methodology through a mediated stakeholder review process,  conducted a valuation analysis of distributed solar for three utility territories, and developed a summary of implementation options for increasing deployment of distributed solar generation in the State.


The original report, delivered to the Legislature on March 2, 2015, includes three volumes which accompany an Executive Summary. An addendum to the study was delivered to the Legislature on April 1, 2015. The revised final report is posted below. For the original report and addendum see our Legislative reports page.
