Energy Storage Solutions Program Energy Storage Solutions (ESS) is a statewide program that provides residential and commercial customers with incentives to install energy storage at their home or business and to use energy storage to the benefit of the grid and electric customers.
Launched in January 2022, the nine-year program is administered by the Connecticut Green Bank (CGB) along with Connecticut's regulated electric distribution companies, Eversource Energy and The United Illuminating Company (UI). In June 2021, PURA issued a final decision as part of its Equitable Modern Grid initiative that established the ESS program, with the aim of deploying 580 MW of electric storage by 2030.
This program enhances grid reliability and ensures homeowners, small businesses, industrial manufacturers, and critical facilities have access to *NEW* Recent Changes (2025 only) In the latest annual ESS program review, the Authority authorized several changes to the program, including: Shifting most participant compensation to a performance-based structure, with a limited enrollment incentive available upon program entry, to better align payments with delivered value and minimize ratepayer risk; Establishing a $350 application fee for commercial applicants to reduce administrative costs borne by ratepayers and discourage speculative applications; Permitting non-export batteries to participate, provided interconnection was completed prior to 2026, to cost-effectively leverage existing storage assets; and Establishing a temporary working group to evaluate the potential inclusion of bidirectional electric vehicles in the next ESS annual review, with the objective of enhancing system benefits and reducing overall electric vehicle ownership costs for ratepayers.
