Energize Connecticut

What Energize Connecticut does

Energize Connecticut is a state-backed energy efficiency initiative operating under Connecticut Public Acts 11-80, 13-298, and 21-139, with statutory establishment in 1998 by the Connecticut State Legislature. The initiative is governed by an independent Energy Efficiency Board and overseen by the Department of Energy and Environmental Protection (DEEP), with the Connecticut Green Bank and utility sponsors (Eversource, United Illuminating, Connecticut Natural Gas, Southern Connecticut Gas) as core partners. Funding flows through the Energy Efficiency Fund, supported by the Combined Public Benefits Charge on Eversource and UI electric customers and a conservation charge on gas customers of CNG, SCG, and Eversource.

The initiative's product portfolio spans residential, commercial, industrial, multifamily, municipal, agricultural, and educational customer segments, delivered through energy assessments (Home Energy Solutions, Income-Eligible variant, Small Business Energy Advantage, Multifamily Initiative, Manufacturing assessments), clean heating and cooling technologies (air source and ground source heat pumps, heat pump water heaters), weatherization (insulation, triple pane windows), LED lighting, ENERGY STAR appliances, appliance recycling, demand response, smart thermostats, and a Renewable Energy Solutions program running 2022-2027. Financing products include Smart-E Loans (0.99% limited-time offer through June 2026), CT Heating Loans (0.99% up to $15,000), C-PACE financing, on-bill multifamily loans, and Small Business & Municipal Loan Programs with 0% options for qualifying applicants.

Go-to-market relies on three layers: (1) utility billing-based program awareness and on-bill financing reaching approximately 1.95 million electricity customers and 338,000 gas customers across Connecticut; (2) a certified contractor ecosystem comprising 690+ contractors across the Heat Pump Installer Network, Insulation Installers Network, and Advanced Duct Sealing Network, plus 223+ approved distributors; and (3) outreach and education through the Smart Energy Living and Energy in Action mobile exhibits, eesmarts K-12 curriculum, Green STEP program, community grants (up to $5,000), and partnerships with museums, Connecticut Technical High School System, and the National Association of Realtors Green Designation. The initiative is structurally not a revenue-generating business; program funding flows through as rebates, incentives, contractor payments, and educational program costs rather than booking commercial revenue.
