Mass. Gen. Laws ch. 164 § 72
An electric company, distribution company, generation company, transmission company or any other entity providing or seeking to provide transmission service may petition the energy facilities siting board for authority to construct and use, or to continue to use as constructed or with altered construction, a line for the transmission of electricity for distribution in some definite area or for supplying electricity to itself, another electric company or a municipal lighting plant for distribution and sale or to a railroad, street railway or electric railroad for the purpose of operating it and shall represent that such line will or does serve the public convenience and is consistent with the public interest. The company or other entity providing or seeking to provide transmission service shall forward at the time of filing such petition a copy thereof to each municipality within such area. The company or other entity shall file with such petition a general description of such transmission line and a map or plan showing the municipalities through which the line will or does pass and its general location. The company or other entity shall also furnish an estimate showing in reasonable detail the cost of the line and such additional maps and information as the energy facilities siting board requires. The energy facilities siting board, after notice and a public hearing in at least 1 of the municipalities affected, may determine that said line is necessary for the purpose alleged, will serve the public convenience and is consistent with the public interest. If the electric company, distribution company, generation company or transmission company or any other entity providing or seeking to provide transmission service shall file with the energy facilities siting board a map or plan of the transmission line showing the municipalities through which it will or does pass, the public ways, railroads, railways, navigable streams and tide waters in the municipality named in said petition that it will cross and the extent to which it will be located upon private land or upon, under or along public ways and places, the energy facilities siting board, after such notice as it may direct, shall hold a public hearing in at least 1 of the municipalities through which the line passes or is intended to pass. The energy facilities siting board may by order authorize an electric company, distribution company, generation company, transmission company or any other entity to take by eminent domain under chapter 79 such lands or such rights of way or widening thereof or other easements therein necessary for the construction and use or continued use as constructed or with altered construction of such line along the route prescribed in the order of the energy facilities siting board. The energy facilities siting board shall transmit a certified copy of its order to the company and the clerk of each affected municipality. The company or other entity may at any time before such hearing modify the whole or a part of the route of said line, either of its own motion or at the insistence of the energy facilities siting board or otherwise and, in such case, shall file with the energy facilities siting board maps, plans and estimates as aforesaid showing such changes. If the energy facilities siting board dismisses the petition at any stage in said proceedings, no further action shall be taken thereon and the company may file a new petition not less than 1 year after the date of such dismissal. When a taking under this section is effected, the company may forthwith, except as hereinafter provided, proceed to erect, maintain and operate thereon said line. If the company or other entity does not enter upon and construct such line upon the land so taken within 1 year thereafter, its right under such taking shall cease and terminate. No lands or rights of way or other easements therein shall be taken by eminent domain under the provisions of this section in any public way, public place, park or reservation or within the location of any railroad, electric railroad or street railway company except with the consent of such company and on such terms and conditions as it may impose or except as otherwise provided in this chapter and no electricity shall be transmitted over any land, right of way or other easement taken by eminent domain as herein provided until the electric company, distribution company, generation company, transmission company or any other entity shall have acquired from the select board, city council or such other authority having jurisdiction all necessary rights in the public ways or public places in the municipality or municipalities, or in any park or reservation, through which the line will or does pass. No land, rights of way or other easements therein in any public way, public park, reservation or other land subject to Article 97 of the Amendments to the Constitution of the Commonwealth shall be taken by eminent domain under this section except in accordance with said Article 97. No entity shall be authorized under this section or section 69R or section 24 of chapter 164A to take by eminent domain any lands or rights of way or other easements therein held by an electric company or transmission company to support an existing or proposed transmission line without the consent of the electric company or transmission company.
No electric company, distribution company, generation company, transmission company or any other entity providing or seeking to provide transmission services shall be required to petition the energy facilities siting board under this section unless it is seeking authorization to take lands, rights of way or other easements under chapter 79.
