Solar Net Metering Credit

The net metering credit is based on the average Real Time Independent System Operator-New England (ISO-NE) price for all hours in the month prior to the current billing month between 9 a.m. - 4 p.m. The credit amount for energy generated that exceeds a customer's purchases from CMLP is a variable amount as described in the Residential Net Metering with Banking rate.


ISO-NE oversees the constant availability of electricity in New England by ensuring the day-to-day operation of New England's bulk power generation and transmission system, ensuring the fair administration of the region's wholesale electricity markets, and managing regional planning.
