Rates

All you need to know about how we determine our rates.

GMP represents a great value for customers. Based on the latest figures available, our average rates are among the lowest of all major utilities in New England. It is even more impressive when you consider the fact that GMP has one of the nation’s cleanest power supplies. And that Vermont’s rugged and remote terrain isn’t always the most accommodating for the transmission of electricity.

In the future, rates for former CVPS customers and legacy GMP customers will be combined. For now, we will continue to provide service under separate rate tariffs.
