Connecticut: ZREC, Energy Storage Solutions, and NRES.
Connecticut replaced new ZREC procurement with the Non-Residential Renewable Energy Solutions tariff. Energy Storage Solutions can offer eligible batteries separate payments. Each program has its own eligibility and operating requirements.
The rule in one paragraph
Connecticut's LREC and ZREC solicitations closed to new projects and were replaced by the Non-Residential Renewable Energy Solutions (NRES) tariff. Under a buy-all election the project is paid at the approved tariff rate; under netting, on-site consumption is combined with export credits tied to the applicable retail rate. They are two different mechanisms, not one fixed energy price.
Because the tariff election changes how generation is valued against on-site consumption, the election is a modeling decision, not a form field.
Primary source: Eversource — Connecticut NRES; Energy Storage Solutions — current program manual.
Who it applies to
Eligible non-residential Eversource and United Illuminating accounts, including commercial, industrial, municipal, non-profit and multifamily properties. Eligibility is account-specific, not statewide.
Energy Storage Solutions has separate rules, including enrollment classifications and dispatch participation during declared events of one to three hours. From April 1, 2026 the standard commercial and industrial enrollment incentive is not available, while priority commercial and industrial projects may receive $10/kWh.
What it costs / what it pays
NRES pays for generation across the tariff term. Energy Storage Solutions performance payments are $325/kW for small and medium classifications and $275/kW for large in years 1–5, then $175/kW in years 6–10, settled on measured seasonal performance rather than installed nameplate. Installed kW alone is not revenue: events run one to three hours, and any model has to account for available battery energy, reserve, losses, degradation and actual dispatch.
In Connecticut the demand-charge component of commercial bills often makes the battery the larger part of the operating case, not the smaller.
How NOI's structure fits
We model the tariff election, the storage incentive and the demand-charge saving as one case, keeping program receipts, project costs and the owner's contracted share separate rather than merged into a single number.
What the owner receives is set in the project agreement after underwriting, and is not the same figure as the program receipts.
