Connecticut energy storage incentives, read as an NOI line.

Energy Storage Solutions pays eligible projects for measured battery dispatch during grid events. We assess those payments alongside potential demand-charge savings, then agree the funding and operating structure for your property.

Illustrative only—not customer data, measured performance or guaranteed savings. Actual billed demand and financial effect depend on the utility tariff, billing interval, ratchets, load profile, battery constraints, dispatch and operating agreement. Demand determinants, intervals and ratchets vary by tariff and utility.

Program rules reviewed September 18, 2026. Read the Energy Storage Solutions program manual. Eligibility and payments remain subject to current program approval.

Illustrative peak-demand example
UNMANAGED LOAD

Without storage dispatch

A short load spike creates the highest metered interval in this illustrative billing period.

MODELED PEAK MANAGEMENT

With modeled storage dispatch

The modeled control strategy attempts to reduce qualifying peaks within the battery’s power, energy and state-of-charge constraints.

What we handle

Program paperwork, interconnection and dispatch, coordinated for the property.

Enrollment.

We prepare the Energy Storage Solutions application, size the system against your interval data, and manage the Green Bank and utility review.

Operation.

We coordinate dispatch and monitor available energy against the agreed operating plan and program requirements.

Reporting.

Clear reporting separates estimated bill savings, measured-dispatch receipts, project costs and the owner's contracted share.

Questions

Connecticut storage incentives: questions we get

What does Energy Storage Solutions actually pay a commercial owner?

+

Payments depend on measured dispatch performance, not battery nameplate size. Current commercial rates are $325/kW for small and medium systems and $275/kW for large systems in years 1–5, then $175/kW in years 6–10. New standard commercial enrollment from April 1, 2026 has no upfront enrollment incentive; priority-project eligibility may differ. Confirm the current program rules and your agreement before modeling receipts.

Which utilities are eligible?

+

Eversource and United Illuminating commercial customers. The program is administered by Connecticut Green Bank under PURA oversight.

Do I need to spend capital?

+

Funding is agreed after the property review. A project may be owner-funded, financed or owned by a third party, subject to underwriting and contract terms. We explain your capital requirement and responsibilities before you commit.

How does storage change my demand charge?

+

Storage can reduce billable demand by discharging during relevant peak periods. Savings depend on your tariff, interval load, available battery energy and dispatch strategy; program events and site peak management must be modeled together.

Can I combine storage with the federal tax credit?

+

Solar and storage have different federal credit deadlines. Qualifying solar that begins construction after July 4, 2026 generally must be placed in service by December 31, 2027. Storage follows separate rules. Projects that began construction earlier must meet the continuity requirements. Eligible equipment and sourcing requirements also apply, so credit value depends on the project, its ownership, its construction dates and the eligibility requirements it meets. Connecticut's storage program runs separately from federal credits.
