Commission approval of a proposed transmission line; nonwires alternatives.
The commission may approve or disapprove all or portions of a proposed transmission line and shall make such orders regarding its character, size, installation and maintenance and regarding nonwires alternatives to the proposed transmission line as are necessary, having regard for any increased costs caused by the orders. In its review and consideration of nonwires alternatives, as required by subsection 2‑D, the commission shall give preference to the nonwires alternatives that have been identified as able to address the identified need for the proposed transmission line most cost-effectively. When the cost-effectiveness of the identified nonwires alternatives are reasonably equal, the commission shall give preference to the alternatives that produce the lowest amount of local air emissions, including greenhouse gas emissions.
6.
Commission order; certificate of public convenience and necessity.
In its order, the commission shall make specific findings with regard to the public need for the proposed transmission line. The commission shall make specific findings with regard to the likelihood that nonwires alternatives can sufficiently address the identified public need over the effective life of the transmission line more cost-effectively. If the commission finds that a public need exists, after considering whether the need can be reliably and more cost-effectively met using nonwires alternatives, it shall issue a certificate of public convenience and necessity for the transmission line. In determining public need, the commission shall, at a minimum, take into account economics, reliability, public health and safety, scenic, historic and recreational values, state renewable energy generation goals, the proximity of the proposed transmission line to inhabited dwellings and nonwires alternatives to construction of the transmission line, including energy conservation, distributed generation or load management. If the commission orders or allows the erection of the transmission line, the order is subject to all other provisions of law and the right of any other agency to approve the transmission line. The commission shall, as necessary and in accordance with subsection 7 and 8, consider the findings of the Department of Environmental Protection under Title 38, chapter 3, subchapter 1, article 6, with respect to the proposed transmission line and any modifications ordered by the Department of Environmental Protection to lessen the impact of the proposed transmission line on the environment. A person may submit a petition for and obtain approval of a proposed transmission line under this section before applying for approval under municipal ordinances adopted pursuant to Title 30‑A, Part 2, Subpart 6‑A; and Title 38, section 438‑A and, except as provided in subsection 4, before identifying a specific route or route options for the proposed transmission line. Except as provided in subsection 4, the commission may not consider the petition insufficient for failure to provide identification of a route or route options for the proposed transmission line. The issuance of a certificate of public convenience and necessity establishes that, as of the date of issuance of the certificate, the decision by the person to erect or construct was prudent. At the time of its issuance of a certificate of public convenience and necessity, the commission shall send to each municipality through which a proposed corridor or corridors for a transmission line extends a separate notice that the issuance of the certificate does not override, supersede or otherwise affect municipal authority to regulate the siting of the proposed transmission line. The commission may deny a certificate of public convenience and necessity for a transmission line upon a finding that the transmission line is reasonably likely to adversely affect any transmission and distribution utility or its customers.
6-A.
High-impact electric transmission line; certificate of public convenience and necessity.
The commission shall evaluate and render a decision on any petition for a certificate of public convenience and necessity for a high-impact transmission line.
6-B.
Reasonable consideration of nontransmission alternatives.
6-C.
High-impact electric transmission line; legislative approval.
In addition to obtaining a certificate of public convenience and necessity, a high-impact electric transmission line may not be constructed anywhere in the State without first obtaining the approval of the Legislature, except that any high-impact electric transmission line crossing or utilizing public lands designated by the Legislature pursuant to Title 12, section 598‑A, other than service land, is deemed to substantially alter the land and must be approved by the vote of 2/3 of all the members elected to each House of the Legislature.
6-D.
High-impact electric transmission line; geographic prohibition.
Notwithstanding subsection 6‑C, a high-impact electric transmission line may not be constructed in the Upper Kennebec Region. For the purpose of this subsection, "Upper Kennebec Region" means the approximately 43,300 acres of land located between the Town of Bingham and Wyman Lake, north along the Old Canada Road, Route 201, to the Canadian border, and eastward from the Town of Jackman to encompass Long Pond and westward to the Canadian border, in Somerset County and Franklin County.
