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 launching 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.

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.
