Select a Payment Beneficiary

For the Buy-All Incentive, the customer of record may designate a payment beneficiary to receive a percentage of the total tariff compensation. This beneficiary cannot be the customer of record. If no beneficiary is designated, the customer of record will receive all incentives as monetary on-bill credits.

For the Netting Incentive, the customer of record may designate a beneficiary to receive the Renewable Energy Certificate (REC) incentive payment paid out once every quarter. This beneficiary can be the customer of record.

• If you need to make a change to the beneficiary and/or percent allocation of on-bill credits vs. direct payments, download the Payment Beneficiary Revision form.

Identify the System Owner

• If the customer will own the system, download and complete the Direct Ownership Customer Disclosure form.
• If a third party will own the system, download and complete the Third Party Ownership Customer Disclosure form.

The RRES program offers additional incentives (“adders”) for customers who meet income eligibility criteria or live in an economically distressed municipality. For basic information on adders and their eligibility criteria, see the customer-focused RRES webpage. 

The Federal government offers additional tax credits for projects in qualifying areas through the Low-Income Communities Bonus Credit Program and the Energy Community Tax Credit Bonus. Federal incentives are in addition to RRES incentives and adders, allowing customers to maximize their incentive benefits.  The below map displays the geographic overlap between Connecticut’s Distressed Municipality list and census tracts that may be eligible for the additional Federal tax incentives. The census tract codes displayed below can also be downloaded as a PDF.
