Key Issues
- —
Eversource electric distribution rate case: PURA is evaluating Eversource's pending rate case filing seeking recovery of significant capital investments in grid hardening, AMI deployment, and vegetation management, with intervenors challenging the prudency of certain expenditures and the proposed ROE.
- —
Grid modernization and EV infrastructure investment: PURA is overseeing proceedings under Connecticut's Act Concerning Climate Change (PA 21-7) requiring utilities to file distribution system plans integrating EV charging, distributed energy resources, and non-wires alternatives, with contested cost recovery structures under active review.
- —
Gas utility new service extension moratorium and decarbonization policy: PURA and the legislature are engaged in ongoing proceedings addressing whether gas utilities should be permitted to extend new gas infrastructure given the state's 2040 building decarbonization targets, creating regulatory uncertainty for Avangrid's gas distribution companies around capital planning.
- —
Utility performance accountability and storm response metrics: Following multi-year enforcement actions stemming from Tropical Storm Isaias penalties against Eversource, PURA continues to administer enhanced performance metrics and is evaluating whether to impose additional service quality incentive and penalty mechanisms in upcoming rate proceedings.
- —
PFAS and emerging contaminant cost recovery for water utilities: Connecticut Water and other regulated water utilities are seeking PURA approval to recover costs associated with PFAS treatment infrastructure upgrades required by EPA's April 2024 maximum contaminant level rules, with active contested proceedings over the allocation of costs between ratepayers and shareholders.
