How Much Is the Energize Connecticut Window Rebate?
The 2026 program offers $100 per qualifying replacement window.
Your total rebate depends on the number of eligible windows installed. For example, replacing 10 qualifying windows could make you eligible for a $1,000 rebate, subject to program requirements and approval.
The rebate is available to eligible residential customers of Eversource and United Illuminating (UI). Your home must meet the program's eligibility requirements, and the windows must be professionally installed.
