How Connecticut's Energy Storage Solutions program pays home battery buyers after the April 2026 restructuring, and the quote checks that matter before signing.
Budget
Quick answer: Connecticut's Energy Storage Solutions program restructured its incentive on April 1, 2026. New applicants now get a smaller enrollment incentive ($30 per kWh, or $130 per kWh on qualifying grid-edge circuits) instead of the old $250-$600 per kWh upfront payment, in exchange for a bigger 10-year performance incentive ($300-$550 per kW each year) tied to mandatory dispatch. Price the installed system first, confirm which structure applies to your contract, then treat either incentive as a bonus, not the reason to sign.

Tradeoff
A lower quote is not better until the backup design, usable kWh, and incentive assumptions match.

The goal is not to pick the biggest battery. The goal is to understand what the quote includes, whether the design fits your outage pattern, and what the same usable capacity should cost in your market. Start with how to read a battery quote and the real cost of a home battery benchmarks if you have not already, then layer the program specifics below on top.

What changed on April 1, 2026
Before April 1, 2026, Energy Storage Solutions paid a large upfront incentive of up to $250 per kWh for standard residential customers, $450 per kWh for underserved communities, or $600 per kWh for low-income households, capped at $16,000 per project or 50 percent of total project cost. That incentive required enrollment in Passive Dispatch: the utility could automatically discharge up to 80 percent of the battery on non-holiday weekdays in June, July, and August, from 3 p.m. to 8 p.m.
For applications approved on or after April 1, 2026, the program dropped the large upfront payment in favor of a much smaller enrollment incentive paired with a bigger, longer performance incentive tied to Active Dispatch instead of the old automatic summer-only schedule. If your project was approved before that date, ask your installer directly which structure your contract actually falls under. Energy Storage Solutions has not published a plain grandfathering summary alongside the new rates, so this is a confirm-before-signing item, not something to assume either way.
How the current incentive works
Enrollment incentive (paid upfront):
Customer class
Rate
Standard residential
$30 per kWh of battery capacity
Grid-edge residential
$130 per kWh of battery capacity
Performance incentive (paid twice a year, for 10 years):
Customer class
Rate
Standard
$300 per kW-year
Underserved communities
$450 per kW-year
Low-income
$550 per kW-year
Grid-edge status is not self-declared. It is based on whether your address sits on one of the utility circuits with the highest number or longest duration of major-storm outages since July 2012, and Eversource and United Illuminating each publish a map to check it. Ask your installer to confirm your circuit's status before you count the higher rate, rather than taking a verbal "you probably qualify" at face value.
A standalone battery, with no solar attached, is also eligible. The program explicitly allows a battery that charges from the grid rather than from panels.
Active Dispatch: what it means for backup
The new structure ties the performance incentive to Active Dispatch, meaning the utility calls roughly 50 summer events and about 5 winter events per program year, with events typically running about 3 hours and 24 hours of notice. Dispatch is paused ahead of forecast storms expected to cause outages in your area.
Before enrolling, ask the same questions covered in our VPP enrollment guide: what backup reserve is protected during an event, whether you can decline an individual dispatch without losing the incentive, and how event participation is tracked. A performance incentive is only as good as the reserve settings that keep your battery useful in an actual outage.
Quote red flags
The installer quotes the pre-2026 $250-$600 per kWh enrollment figure for a project applying after April 1, 2026.
The enrollment incentive and the performance incentive are collapsed into a single "incentive" number instead of shown separately.
No mention of Active Dispatch, event frequency, or backup reserve settings.
The quote does not name Eversource or United Illuminating specifically, even though eligibility and dispatch rules run through your utility account.
A 2026 quote still markets a 30 percent federal credit on a straight cash or loan purchase. The federal 25D credit expired at the end of 2025, and the details are in the battery tax credit 2026 guide.
What to ask before signing
What is the installed price per usable kWh, before any ESS incentive?
Am I enrolling under the current post-April 2026 structure, and does my project qualify for standard, underserved, or grid-edge rates?
How many dispatch events happen per year, how long do they run, and what backup reserve is protected during one?
Is this whole-home backup or essential-loads backup?
Is panel work included, excluded, or unknown?

Home Battery Guide may earn from affiliate links or flat-fee referrals to named vetted installers. Rankings do not move with compensation. We do not sell the same lead to multiple installers, and a referred installer quote still has to pass the same quote check.
FAQ
Is Connecticut Energy Storage Solutions still active?
Yes. The program runs through December 31, 2030, but the incentive structure changed on April 1, 2026, so a quote built on older numbers is out of date.
Is Connecticut Energy Storage Solutions the same as ConnectedSolutions?
No. Energy Storage Solutions is a Connecticut-specific enrollment and dispatch incentive administered with the Connecticut Green Bank, Eversource, and United Illuminating. ConnectedSolutions is a separate demand-response program used in Massachusetts and Rhode Island. Buyers researching multiple New England states sometimes see both names and assume they are interchangeable. They are not, and the payment structures differ.
Do I need solar to qualify for Energy Storage Solutions?
No. A standalone battery that charges from the grid can enroll. Pairing with solar is common but not required.
What is a grid-edge customer?
A customer on one of the utility circuits with the highest number or longest duration of major-storm outages since July 2012, confirmed through the Eversource or United Illuminating grid-edge map rather than self-reported.
Does the incentive make any battery quote a good deal?
No. It can improve the economics, but an inflated installed price can still erase most of that value. Check the price per usable kWh the same way you would in any market before counting the incentive as savings.
