Connecticut Renewable Energy Solutions Interconnections

Information for installers interconnecting residential and non-residential projects in Connecticut for Renewable Energy Solutions.

What is Renewable Energy Solutions?

Renewable Energy Solutions is a Connecticut incentive program for solar and other renewable energy launched in 2022. Through this program, customers can sell power generated and any renewable energy certificates (RECs) to Eversource.

Note: If a customer applied to install solar before January 1, 2022, they are participating in the Net Metering Program.

Residential Interconnections

System installers or their authorized agents are responsible for applying to the program on behalf of system owners and customers of record.

This application process is a part of the interconnection process, but additional information is required. We review the program and interconnection applications at the same time. After reviewing the program guidelines and completing the required forms, you may apply for interconnection.

Program Information

Through Residential Renewable Energy Solutions, Connecticut customers can offset the cost of the electricity with energy generated with solar or other renewable energy technologies.

Webinars

Note: solar PV projects can also interconnect under Rate 980 as an alternative to RRES, however this is not typically preferred by residential customers. For more information, see our Rate 980 FAQ.

Technical Guidelines

Specific technical guidelines must be met to participate in Renewable Energy Solutions.

Forms

When applying for the program, you must submit specific forms based on the customer's selections.

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.

Program Data

When determining if solar is right for you, we recommend comparing multiple estimates from different solar installers. To help with your comparisons, here are some average costs from applications approved for the Residential Renewal Energy Solutions (RRES) program over the last six months. Compare these costs to those included in your installation estimates and those listed on your Residential Renewable Energy Disclosure document. The average price is in $/kWh and is based on data from the previous six months.

(PPA) price ($/kWh)
Average Lease Price ($/kWh)Average System Size (kW DC)

Environmental Justice Guidance

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.

The Connecticut environmental justice mapping tool may also be useful to stakeholders interested in environmental justice. The tool is an interactive resource that allows users to explore environmental health and socioeconomic conditions by region. Links to the tool and instructive user guides may be viewed here.
