Payments decline each year because battery capacity degrades, which reduces the average power the system can sustain during a dispatch event.

These figures are a non-binding estimate, not an offer or a guarantee of payment. Privacy policy.

These are incentive estimates, not savings and not an offer. This tool estimates payments available through the Connecticut Green Bank Energy Storage Solutions program. It does not estimate electricity bill savings, system cost, net cost after incentives, or payback period. Your actual out-of-pocket cost depends on equipment, installation, and financing that are not modeled here.

Performance incentives are variable and are not guaranteed. Actual payments for Active Dispatch can vary significantly based on battery degradation, discharge limits set by the manufacturer or operator, customer participation and opt-out, weather events, and system design. Nothing here obligates any party to pay any amount.

Final approval rests with Connecticut Green Bank. Enrollment Incentive approval is subject to review of a complete application. Program rules, rates, and eligibility can change. Refer to the current Program Manual at energystorageCT.com for authoritative terms.

Eligibility designations require verification. Underserved community, income-qualified, and Grid-Edge status must be confirmed through the program. Selecting them here does not establish eligibility.
