Net metering and on-bill credits that you receive from Eversource work the same way whether you are enrolled with the Community Choice Electricity Program or with Eversource’s basic service. If you participate in the Program, you will continue to receive the same net metering credits directly from Eversource, while also benefiting from the Program.
If during a billing period you generate more electricity than you use, Eversource will calculate a net metering credit at the basic service rate on the amount of excess electricity exported to the grid. This credit, located in the delivery portion of your bill, is calculated exactly the same way whether you are part of the Program or not.
If during a billing period you generate less electricity than you use, you will only pay for the net electricity that you draw from the grid. You will be charged at the Program rate rather than the basic service rate on the supply portion of your bill.
