An Act relative to municipal light plants

HD 553 allows municipal light boards (local utility boards) to provide infrastructure services like pole installation and equipment maintenance to other public utilities - including state, tribal, or municipal utilities - both inside and outside Massachusetts. It permits these boards to sell, rent, or lease related equipment and ensures employees working on such projects have the same labor rights as if performing duties within their home municipality. The bill modifies existing laws to explicitly include tribal utilities (as defined under federal regulations) and expands the scope of services municipal light plants can offer beyond their own service areas. This directly affects municipal light boards, tribal utilities, and other public utility entities seeking infrastructure partnerships.
