Bridgeport homeowners are United Illuminating customers. UI is now owned by Avangrid (the U.S. subsidiary of Spain’s Iberdrola) and serves the New Haven and Bridgeport shoreline corridor — New Haven, Bridgeport, West Haven, Milford, Shelton, Derby, Ansonia, Stratford, and surrounding southwestern Connecticut communities.
UI administers the RRES program identically to Eversource under Connecticut PURA regulations. Bridgeport solar homeowners choose at interconnection between the Netting Tariff (self-consume solar, export excess at approximately 28¢ per kilowatt-hour retail-rate credit, credits carry forward up to 12 months with annual true-up) or the Buy-All Tariff (UI purchases all production at the 2026-locked rate of $0.3289 per kilowatt-hour for 20 years). The Solar Energy Adjustment of $0.0402 per kilowatt-hour applies to Netting Tariff enrollees, reducing the effective net credit slightly below the headline retail rate.
One practical difference from Eversource territory: UI’s interconnection process requires a separate smart meter installation that Eversource does not mandate for residential systems under 25kW. This adds approximately 2–4 weeks to UI’s interconnection timeline compared to Eversource. Total interconnection time for Bridgeport installations typically runs 6–10 weeks from application to Permission to Operate — longer than Hartford’s 4–8 week Eversource timeline. Build this into your project timeline expectations when comparing installer quotes.
Bridgeport’s housing is predominantly multifamily and urban — a mix of two-family and three-family homes, rowhouses, and apartment buildings that creates the same rooftop access constraint seen in other dense Northeast cities. The viable solar candidate pool concentrates among owner-occupied two- and three-family homes where the building owner controls the roof and can capture solar savings across the building’s total electricity load, and single-family homes in Bridgeport’s more residential neighborhoods.
For Bridgeport residents who cannot install rooftop solar, Connecticut’s Shared Clean Energy Facility (SCEF) program provides a meaningful alternative. The SCEF program allows renters, condo owners, and homeowners with unsuitable rooftops to subscribe to a share of a larger community solar installation and receive on-bill credits from United Illuminating — typically 5–15% savings on the subscribed portion of the monthly bill with no upfront cost and no homeownership requirement. Bridgeport’s status as an economically distressed municipality under state criteria makes low-income Bridgeport SCEF subscribers eligible for enhanced bill credits beyond the standard discount and for reduced or eliminated subscription fees — an access provision specifically designed for cities with Bridgeport’s income profile. Virtual net metering through UI allows multifamily building owners to allocate solar credits across multiple tenant meters within the same building.
Bridgeport is primarily United Illuminating (UI) territory. UI serves southwestern Connecticut, with Bridgeport and New Haven as its two largest cities. Eversource serves the majority of Connecticut including Hartford, Waterbury, Stamford’s northern areas, and most of the state’s north and central regions, but Bridgeport proper falls under UI. Your utility bill confirms which company serves your address. If your bill comes from United Illuminating or shows the UI logo (now under Avangrid ownership), you’re in the UI framework with its specific interconnection process, including the smart meter installation requirement and the 6–10 week interconnection timeline.
