Terms Used In Maine Revised Statutes Title 35-A Sec. 3147
- Baseline: Projection of the receipts, outlays, and other budget amounts that would ensue in the future without any change in existing policy. Baseline projections are used to gauge the extent to which proposed legislation, if enacted into law, would alter current spending and revenue levels.
- Commission: means the Public Utilities Commission. See Maine Revised Statutes Title 35-A Sec. 102
- Cost-effective: means , with respect to nonwires alternatives, that benefits exceed costs, as determined by benefit-cost analysis conducted pursuant to section 3132?C, subsection 2. See Maine Revised Statutes Title 35-A Sec. 3131
- Customer: includes any person, government or governmental division which has applied for, been accepted and is currently receiving service from a public utility. See Maine Revised Statutes Title 35-A Sec. 102
- Transmission and distribution utility: means a person, its lessees, trustees or receivers or trustees appointed by a court, owning, controlling, operating or managing a transmission and distribution plant for compensation within the State, except where the electricity is distributed by the entity that generates the electricity through private property alone solely for the use of:
2. Priorities identified; stakeholder input. Beginning November 1, 2022, then every 5 years thereafter, the commission shall initiate a proceeding to identify the priorities to be addressed in a filing by a covered utility regarding a grid plan that will assist in the cost-effective transition to a clean, affordable and reliable electric grid. The commission shall hold technical conferences or stakeholder workshops before the filing to identify priorities, assumptions, goals, methods and tools that will assist the covered utility in developing a grid plan.
[PL 2021, c. 702, §8 (NEW).]
3. Commission order. At the conclusion of the technical conferences and stakeholder workshops held under subsection 2, the commission shall issue an order directing a covered utility to submit a filing to the commission that addresses the priorities identified in the proceeding initiated pursuant to subsection 2 and includes the additional components identified in subsection 4.
[PL 2021, c. 702, §8 (NEW).]
4. Additional components; submission. A covered utility shall submit a filing to the commission within 18 months of the issuance of an order by the commission pursuant to subsection 3. In addition to addressing the priorities specified in the commission order, the filing must:
A. Assess the electric system of the covered utility and its relationship to the regional grid; [PL 2021, c. 702, §8 (NEW).]
B. For elements of the filing related to customer energy consumption and usage characteristics, reference and incorporate relevant elements of the Efficiency Maine Trust triennial plan developed under section 10104, subsection 4, including all of the trust’s analysis of cost-effective energy efficiency potential and plans to implement energy efficiency programs, demand management programs, beneficial electrification programs such as heat pump and electric vehicle initiatives, energy storage initiatives and analysis of nonwires alternatives; [PL 2021, c. 702, §8 (NEW).]
C. Include at least 2 potential planning scenarios, at a minimum, a baseline scenario and a scenario of high-penetration distributed energy resources and end-use electrification. When applicable, the planning scenarios must incorporate mechanisms for achieving the priorities established pursuant to subsection 2, including, but not limited to, cost-effective policies, programs, rates, use of software or technology and infrastructure planning, including nonwires alternatives; [PL 2021, c. 702, §8 (NEW).]
D. Include, at a minimum, the following:
(1) Forecasts of projected load, including forecasts of end-use electrification, energy efficiency and distributed energy resources;
(2) Baseline energy supply data and assessments, including but not limited to planned generation retirements; new generation that is planned or needed, including generation of electricity from renewable sources; and energy storage installations;
(3) Analysis of hosting capacity, including locational benefits of distributed energy resources and areas of existing or potential system congestion;
(4) Analysis of available and emerging technologies necessary to enable load management and flexibility;
(5) An assessment of the environmental, equity and environmental justice impacts of grid plans; and
(6) An identification of cost-effective near-term grid investments and operations needed to achieve the priorities identified in subsection 2; and [PL 2021, c. 702, §8 (NEW).]
E. Reference and incorporate, as appropriate, all relevant analysis conducted as part of the State’s climate action plan under Title 38, section 577 and relevant information from reports and analysis completed by other state agencies and quasi-independent state entities. [PL 2021, c. 702, §8 (NEW).]
The commission shall make the filing for each covered utility available for public comment for a period of no less than 60 days.

5. Access to information. Consistent with section 1311?A, a covered utility shall ensure to the greatest extent practicable that any information related to the filing is provided in a forum accessible to interested parties and all relevant data and distribution planning modeling tools are available to interested parties.
[PL 2021, c. 702, §8 (NEW).]
Nothing in this section prohibits the commission from holding additional proceedings if the commission determines it is necessary to meet the purposes of this section. [PL 2021, c. 702, §8 (NEW).]
