Massachusetts Net Metering

The Eversource Net Metering program is a renewable rate program available to customers using their own renewable energy source to generate electricity. 

If you are installing distributed generation (e.g., solar panels), or already have a generator, you may be eligible for net metering, a method of measuring the energy consumed and produced by a customer’s generating facility. If you are a customer applying for electrical interconnection, and you want to be considered for net metering, you must also submit the net metering application.

Net Metering is the process of measuring the difference between electricity delivered by Eversource to the customer and electricity generated by the customer with a Class 1, Class 2 or Class 3 net metering facility and fed back to Eversource.

Net metering allows a customer to reduce the amount of energy purchased from an energy supplier and receive compensation for excess energy (exported energy to the grid) produced by the customer's on-site generator.

The Green Communities Act provides for three classes of net metering customers:

Class 1 customers whose generation is not solar, wind, anaerobic digestion or agricultural will continue to receive the average loss-adjusted monthly clearing price set by ISO New England. These customers must submit proof to Eversource that they are a FERC Qualifying Facility.
