Net Metering Program Summary

The state wide net metering program is open to any customer with a generator that has a capacity of 100 kilowatts or less and uses a renewable energy source, such as solar, wind or water, to produce electricity. Under this option, a customer’s monthly PSNH bill will reflect the difference between the power they generated and the PSNH power they used during that month. Net metering allows a meter to run backwards when generation exceeds usage. If generation exceeds use during a billing period, the excess generation creates a credit that is carried forward to the next billing period. When use exceeds generation in a future billing period, the customer uses the credit before buying from PSNH.
