Company overview

UNITED ILLUMINATING CO

United Illuminating Co. operates as a regional electric utility rooted in the SIC classification for Electric Services, delivering generation, transmission, and distribution services to residential, commercial, and industrial customers along Connecticut’s coastline with a particular focus on reliable, affordable power delivery and grid resilience initiatives. The firm emphasizes customer service programs, energy efficiency offerings, and storm hardening investments while navigating a regulatory environment overseen by state utility commissions and the Federal Energy Regulatory Commission, which demand careful compliance with rate case rulings, environmental mandates, and infrastructure filing requirements. Supply-chain disruptions, volatile fuel costs, cyber threats, and evolving climate-related expectations are among the material risks that underscore the importance of operational rigor and transparent reporting, especially as regional capacity needs fluctuate. Investors should track how United Illuminating manages capital projects and regulatory approvals, and for real-time disclosure tracking, view live SEC filings on Earnings Feed.
