The Maine Public Utilities Commission has issued rules and procedures for Small Generator Interconnections under Chapter 324.  These rules and procedures establish statewide standards for the interconnection of small renewable energy facilities to the energy grid.  The purpose of these rules and procedures is to increase the efficiency of the interconnection process, encourage the increased use of renewable energy and distributed generation.  We have provided links to the forms and agreements that need to be completed in order to begin the process.

For an overview of the requirements, see CMP’s Sch B  -Transmission & Distribution Interconnection Requirements for Generation, also known as "The Blue Book".
