Key Issues
- —
CMP grid modernization and Advanced Metering Infrastructure (AMI) deployment: MPUC is evaluating CMP's AMI investment plan and associated rate recovery, including scrutiny of cost-benefit analyses and data privacy protections under Maine's relatively stringent customer data statutes.
- —
Potential municipalization of CMP and Versant Power: The Pine Tree Power initiative, following a 2023 referendum defeat, continues to generate legislative and regulatory activity; successor proposals and MPUC proceedings on utility accountability remain active in the 2025-2026 legislative session.
- —
Renewable energy integration and transmission interconnection backlog: MPUC and the Maine Office of the Public Advocate are engaged on queue reform and cost allocation for new generation interconnecting to the ISO-NE system, particularly offshore wind projects tied to Maine's 2030 goals.
- —
Natural gas system contraction and stranded cost risk: As Maine advances building electrification and heat pump incentive programs, MPUC faces pressure to develop a framework for managing declining gas throughput, stranded asset recovery, and equitable transition costs for remaining ratepayers.
- —
Electric vehicle infrastructure cost recovery: Multiple proceedings address how EV charging infrastructure investments by CMP and Versant should be treated for ratemaking purposes, including whether utility-owned charging qualifies for rate base inclusion under Maine law.
Upcoming
