Connecticut: ZREC, Energy Storage Solutions, and NRES.
Connecticut retired ZRECs and replaced them with the Non-Residential Renewable Energy Solutions tariff, while Energy Storage Solutions pays separately for the battery. The two programs are usually modeled together.
The rule in one paragraph
Connecticut's ZREC solicitations closed to new projects and were succeeded by the Non-Residential Renewable Energy Solutions (NRES) tariff, which pays a fixed rate for generation under either a buy-all or netting election. Energy Storage Solutions is a separate statewide program paying upfront and performance-based incentives for behind-the-meter batteries.
Because the tariff election changes how generation is valued against on-site consumption, the election is a modeling decision, not a form field.
Who it applies to
Non-residential customers of Eversource and United Illuminating, including commercial, industrial, municipal, non-profit and multifamily properties.
Storage incentives follow separate program rules, including dispatch participation requirements during declared events.
What it costs / what it pays
NRES pays for generation across the tariff term; Energy Storage Solutions pays both at installation and for performance during called events.
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
NOI models the tariff election, the storage incentive and the demand-charge saving as one case, then funds and operates the whole system.
Owners see it as one number: the monthly income the property earns, with the dispatch obligation handled by NOI.
