Mass. Gen. Laws ch. 164 § 69R
An electric or gas company, generation company or wholesale generation company may petition the board for the right to exercise the power of eminent domain with respect to a facility, large clean transmission and distribution infrastructure facility or small clean transmission and distribution infrastructure facility, specified and contained in a petition or application submitted in accordance with sections 69J, 69T or 69U, or a bulk power supply substation if such company is unable to reach an agreement with the owners of land for the acquisition of any necessary estate or interest in land. The applicant shall forward, at the time of filing such petition, a copy thereof to each city, town and property owner affected.
The company shall file with such petition or have annexed thereto:
The board, after such notice as it may direct, shall hold at least 1 public hearing in the community in which the land to be taken is located. For facilities involving takings in several communities, the hearing shall be held in communities in proximity to the land to be taken, as determined by the board. The board may thereafter authorize the company to take by eminent domain under chapter 79 such lands necessary for the construction of the facility as are required in the public interest, convenience and necessity. The board shall transmit a certified copy of its order to the company and to the clerk of each affected municipality.
If the board dismisses the petition at any stage in the 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.
Following a taking under this section, the electric or gas company may forthwith proceed to utilize such land. If the electric or gas company shall not utilize the lands so taken for the purpose or purposes authorized in the department's order within such time as the board shall determine, its rights under such taking shall cease and terminate.
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.
This section shall not be construed as abrogating the board's jurisdiction described in section 72 in respect to transmission lines or the board's jurisdiction described in sections 75B to 75G, inclusive, in respect to natural gas transmission lines.
