We save snapshots of the Massachusetts rateboard a few times per day so we can show you how supplier offers have changed over time. You can use these charts to see how average offers have changed over the past 6 months, recent supplier rate updates, and offer history for a specific supplier.
Suppliers in National Grid can update their offers frequently as electricity market conditions change, while the National Grid default service rate moves only a few times a year.
