United Illuminating, an investor-owned utility (IOU), is the primary electric utility for the City of Bridgeport. The primary natural gas supplier for Bridgeport is Southern Connecticut Gas, an IOU. In 2007, the Connecticut legislature enacted Public Act 07-242, an act concerning electricity and energy efficiency, which places new requirements for energy efficiency and establishes new regulatory mechanisms for utilities. To learn more about the state requirements for electric and gas efficiency, please visit the Connecticut page of the State Database.

The Aquarion Water Company is the private utility that provides the City of Bridgeport with drinking water services, wastewater treatment, and stormwater management.

Low-Income & Multifamily EE Programs List All

Low-Income Programs

Both United Illuminating and Southern Connecticut Gas participate in the Home Energy Solutions—Income-Eligible Program (HES-IE) available to qualified low-income residential customers in both single and multifamily buildings. Eversource also runs New Construction, Retail Products, and Residential Financing programs for income-eligible customers. The HES-IE program provides no-cost weatherization measures and low-cost energy efficiency upgrades. Direct-install weatherization measures include health and safety testing, blower door guided air sealing, duct sealing, installation of efficient domestic hot water products such as low flow aerators, low flow showerheads, and pipe wrap. Additionally, during the direct install visit, the entire home is evaluated for the potential of add-on measure installations which are classified as appliances, insulation, window, hot water systems, HVAC system replacements. There may be a co-pay associated with add-on measures.

HES-IE program implementers work with community partners to promote the program, such as local public health departments, nonprofits running lead abatement programs, hospitals, local housing agencies, and Community Action Agencies. HES-IE also coordinates with the Weatherization Assistance Program, as the programs cost share all energy efficiency products to help maximize the WAP funding on health and safety barriers. Additionally, HES-IE partners with lead abatement programs and hospitals to help leverage their health and safety funds to incorporate energy efficiency into as many homes as possible.

In 2019, United Illuminating achieved 4,226 MWh of savings, while spending $4,180,741 on its low-income program and serving 6,538 customers. Southern Connecticut Gas’s low-income programs achieved 0.30 MMtherms of savings while spending $3,049,996 on its low-income programs and serving 5,314 customers in 2019.

Multifamily Programs

Both United Illuminating and Southern Connecticut Gas participate in Energize Connecticut’s Multifamily Initiative. This comprehensive program provides customized solutions for existing multifamily properties with five or more dwelling units and includes: assistance with energy efficiency upgrade projects, comprehensive energy assessments of the building's energy-saving opportunities, and incentives and financing for energy-saving efficiency upgrades regardless of fuel type.

The Multifamily Initiative is offered to property managers, property owners, and architects for both market-rate and low-income properties. The Multifamily Initiative is open to any customer, regardless of heating fuel type, within the UI and SCG service territories. The Multifamily Initiative allows a customer to choose their own contractors and create their own contractual agreements with them for work completed. The Multifamily Initiative provides comprehensive energy efficiency upgrades by focusing on the building’s dwelling units, common areas, and exterior spaces. Tenant-occupied areas receive direct install measures, such as air sealing, hot water savings measures, ductwork sealing, and the installation of energy-efficient lighting. The Multifamily Initiative also provides incentives for add-on measures, which may include insulation, heating and cooling equipment, hot water heating equipment, appliances, windows, smart thermostats, and lighting fixtures and controls. The Multifamily Initiative is tailored to the multifamily segment and combines aspects of the Companies’ residential energy efficiency programs, such as Home Energy Solutions (“HES”) and HES-Income Eligible, with the Companies’ commercial and industrial (“C&I”) programs, including the Energy Opportunities, Energy Conscious Blueprint, and Small Business Energy Advantage (“SBEA”) programs. This approach offers flexibility to multifamily property owners and their tenants to save energy and money under a seamless umbrella initiative.

In 2019, United Illuminating’s multifamily efficiency programs achieved 2,804 MWh, while spending $1,426,603 and serving 5,227 housing units in 29 multifamily properties. In 2019, Southern Connecticut Gas saved 0.12 MMtherms while spending $389,922 and serving 4,611 housing units in 24 multifamily properties.

Decarbonization and Climate Change Mitigation Efforts of Energy UtilitiesList All

Utility Climate Mitigation Goal

In 2020, Avangrid, the parent company of United Illuminating, set a goal to reduce greenhouse gas emissions by 35% by 2025 compared to 2015 levels (scope 1 emissions), and achieve carbon neutrality by 2035. To achieve 100% emissions reduction by 2035, Avangrid will need to reduce emissions by 5.9% annually from 2018 levels. 

City-Led Efforts to Decarbonize the Electric Grid

In 2018, the City of Bridgeport partnered with United Illuminating to install an 8,550-panel solar array on the City’s capped landfill, which produces enough energy to supply 400 homes per year. To the best of our knowledge, the City of Bridgeport does not have a formal partnership with United Illuminating to promote renewable generation nor has actively advocated the public utility commission on renewable energy issues.

Efficiency Efforts in Water ServicesList All

Citywide Water Efficiency and Goals

At this time, neither Southern Connecticut Gas nor United Illuminating Company offers joint energy and water efficiency programs with Aquarion Water Company, Bridgeport’s local water utility. At this point, the City of Bridgeport and its water utility have not established a water savings target or goal.

Water Plant Efficiency and Self-Generation

The wastewater utility has not set specific energy efficiency targets or strategies, but it does purchase new energy-efficient equipment when old equipment is at the end of its use cycle. For example, two blowers for the aeration system were recently replaced with one high-efficiency blower to save $250,000 per year in electricity.

The city’s water system currently does not self-generate its own energy, but the City is considering pursuing anaerobic digestion at one of its wastewater treatment plants.
