Detailed Narrative
Electric Demand Growth & Infrastructure Investment
Electric demand growth exceeded 2% in H1 2025, nearly double last year's rate, driven by accelerating electrification and decarbonization efforts. This growth trajectory validates the 10% increase in the 5-year infrastructure investment plan announced in February. The company is strategically upgrading and developing infrastructure to meet demand that is expected to outpace existing capacity in several regions.
Connecticut Regulatory Environment & SB4
The Connecticut legislative session concluded with the passage of Senate Bill 4 (SB4), a comprehensive energy reform bill. SB4 allows for securitization of storm costs incurred from 2018-2025, clarifies Public Utility Regulatory Authority (PURA) requirements for rate request proceedings, and permits the state to use bonds to cover some public benefit programs, which is expected to modestly reduce customer bill impact. Management appreciates the commitment to a transparent and constructive process.
Advanced Metering Infrastructure (AMI) Rollout
The AMI communication network in Western Massachusetts is substantially complete, marking a critical foundational step. Construction of the communication network in Eastern Massachusetts has commenced, and the installation of the first AMI meters in Western Massachusetts has begun. The full transition to AMI meters for all Massachusetts electric customers is projected to take approximately 3 years, aiming to enhance transparency, efficiency, and reliability.
Key Infrastructure Projects & Reliability
Construction of the Cambridge Underground substation, a first-of-its-kind project in the US, is progressing well, with the site advancing toward a final depth of 105 feet. The Outer Cape battery energy storage system, fully commissioned in December 2022, received recognition for its state-of-the-art nature and seamless implementation, having successfully avoided sustained outages for thousands of customers during multiple dispatch events.
Revolution Wind Project Update
The onshore substation construction for the Revolution Wind project, which Eversource oversees, is progressing well and is expected to be substantially complete in August 2025. Testing and commissioning are underway, with backfeed power to the offshore facilities anticipated in early 2026. This construction progress significantly mitigates critical path risk for Eversource's involvement in the project.
Connecticut Supreme Court Ruling on Prudency
A Connecticut Supreme Court decision on Aquarion's 2023 rate case appeal provided important clarity on the applicability of legal standards for rate making. The ruling affirmed prudency standards and entitlement to carrying charges on deferred costs, specifically preventing regulators from applying hindsight in the rate recovery process. This clarification is deemed critical for supporting future capital investments and ensuring cost recovery.
