The United Illuminating Company is an electric transmission and distribution utility based in New Haven, Connecticut.  Our service territory consists of 17 municipalities located in a coastal region that stretches from Fairfield to North Branford and north to Hamden.  The 320,000 residential customers within this area comprise approximately 35% of Connecticut’s total population.

Prior to 1998, UI was a classic electric utility that also owned and managed much of its required electrical generation.  Since that time, and in accordance with state legislation, the company has divested itself of generation and has focused on addressing the distribution requirements of our customers.  Our 800 plus employees pride themselves on the quality of customer service that we provide which includes outage restoration, new customer installations, energy conservation services and much more. 

Recent major company investments to improve system reliability for customers include a major system upgrade and the ongoing Middletown-Norwalk (MN) transmission line project.  The MN project is the largest post-deregulation effort undertaken by UI and it holds the promise of greatly enhancing our ability to continue providing quality energy services to a growing market.

With more than 100 years of service, the company is an independently owned and operated utility, traded on the NYSE under the symbol of our holding company, UIL.
