Program Overview

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 (Eversource) 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 and helping customers across Connecticut, including homeowners, small businesses, industrial manufacturers, and critical infrastructure facilities, be more secure in the face of our changing climate.
  

*NEW* Recent Changes (2023 only)

  
In the latest ESS annual program review, the Authority authorized several changes to the program, including:

  • Increased residential upfront incentive rates by 1.25 times for standard residential customers, and by 1.5 times for low-income and underserved residential customers, up to a maximum of $16,000 per customer;
  • Addressed energy storage data latency requirements;
  • Approved enrollment of additional energy storage technologies; and
  • Approved use of dispatch limiting schedules to address interconnection barriers.
