State Intelligence

Updated Jun 1, 2026

Utility Landscape

Eversource Energy (Connecticut Light and Power)

IOU

Most of Connecticut, serving approximately 1.25 million electric customers across the state

Under sustained PURA scrutiny following performance failures during 2020 Tropical Storm Isaias; subject to ongoing performance-based regulation metrics and executive compensation clawbacks. Filed a distribution rate case in 2023 and has faced repeated challenges to its transmission cost recovery mechanisms.

United Illuminating (Avangrid subsidiary)

IOU

Greater New Haven and Bridgeport areas in southwestern Connecticut, serving approximately 340,000 electric customers

As an Avangrid subsidiary, UI has been subject to PURA scrutiny tied to parent-company governance concerns and Connecticut's broader distrust of Avangrid following offshore wind contract disputes. Ongoing attention to its grid modernization spending and storm response performance standards.

Southern Connecticut Gas (Avangrid subsidiary)

IOU

Southwestern Connecticut coastal corridor including New Haven, Milford, and surrounding communities

Faces increasing regulatory pressure under Connecticut's clean heat transition policy; PURA has scrutinized gas system expansion moratoriums and the utility's long-term capital investment plans in light of the state's 2040 building decarbonization goals.

Connecticut Natural Gas (Avangrid subsidiary)

IOU

Hartford and surrounding central Connecticut communities, serving approximately 170,000 gas customers

Subject to same Avangrid governance scrutiny as sister utilities; PURA has questioned capital expenditure justification for gas infrastructure in context of state decarbonization mandates and potential stranded asset risk.

Yankee Gas Services (Eversource subsidiary)

IOU

Northwestern and north-central Connecticut, serving approximately 220,000 natural gas customers

Operating under a rate structure last comprehensively reviewed in a 2021 case; faces forward-looking regulatory risk tied to Connecticut's gas moratorium discussions and legislative pressure to restrict new gas service extensions in advance of thermal electrification policy implementation.

South Central Connecticut Regional Water Authority

muni

Greater New Haven region, serving approximately 430,000 water customers across 15 municipalities

Regulated by PURA for water rates; has pursued rate increases tied to PFAS remediation capital expenditures and aging infrastructure replacement, drawing intervenor scrutiny from consumer advocates over affordability impacts on lower-income ratepayers.

Key Issues

  • Eversource electric distribution rate case and performance-based regulation framework: PURA is evaluating updated PBR mechanisms that tie allowed revenues to reliability, customer satisfaction, and clean energy integration metrics, with ongoing tension over whether incentive structures adequately discipline storm response and vegetation management performance.

  • Natural gas system transition and moratorium policy: PURA and the legislature are actively developing rules restricting new gas service extensions and potentially requiring utilities to file long-term asset retirement plans, creating significant regulatory uncertainty for Avangrid gas subsidiaries and Yankee Gas over capital recovery and stranded cost treatment.

  • Avangrid governance and affiliate transaction oversight: Following the NECEC transmission controversy and Connecticut's intervention in Avangrid's merger with PNM Resources, PURA is maintaining heightened scrutiny of interaffiliate cost allocations, executive compensation structures, and whether Avangrid's Connecticut utilities are being disadvantaged in capital allocation relative to other subsidiaries.

  • Grid modernization and EV infrastructure investment: PURA is adjudicating distribution system modernization plans filed by Eversource and UI that include substantial smart grid, AMI upgrade, and EV make-ready spending; cost recovery mechanisms and the appropriate rate design for EV charging infrastructure remain contested.

  • PFAS and water quality capital cost recovery: South Central Connecticut Regional Water Authority and other PURA-regulated water companies are seeking rate treatment for significant capital investments required by EPA's 2024 PFAS maximum contaminant level rules, raising affordability and cost allocation disputes before PURA.

Upcoming

2026-07-15

2026-10-20

Estimated PURA technical conference on Eversource and UI joint grid modernization and EV infrastructure plans; staff review of amended AMI deployment schedules and make-ready program cost-benefit analyses expected to produce draft decision in Q4 2026.

Estimated deadline for PURA annual review of utility storm performance scorecards and PBR true-up calculations for 2025 performance year; Eversource and UI must submit compliance filings by this date, with potential revenue adjustments and penalty assessments to follow in early 2027.
