United Illuminating

United Illuminating (UI) is a New Haven-based regional electric distribution company established in 1899. UI is engaged in the purchase, transmission, distribution and sale of electricity and related services to more than residential, commercial and industrial customers in the Greater New Haven and Bridgeport areas. At UI, we've always been dedicated to the communities we serve, and strive daily to provide safe, reliable service to customers. That's why we provide more than electricity. We spearhead conservation efforts, encourage economic growth, assist area businesses and fund important charity organizations through established and often one-of-a-kind programs.
