Where Green Mountain Power Corp sits
It is the dominant supplier in Vermont, serving 226,675 residential customers, so its pricing effectively sets what the state average looks like. Its 22.09¢ per kilowatt-hour sits 11.2% below the Vermont average of 24.89¢.
Its customers use very little electricity by national standards, 586 kilowatt-hours a month against 871 nationally. Dense housing, a mild climate or heating that runs on gas rather than electricity all push consumption down, and any of them can leave a household with a modest bill despite a high rate.
A shareholder-owned company whose rates are set by the state regulator, including an approved return on the capital it has invested. That matters because a bill is not only the cost of generating electricity: it also carries the cost of the network, and who owns that network changes how it is paid for.

How often the power goes out
In 2024 the average Green Mountain Power Corp customer went 667 minutes without electricity across 2.49 interruptions. The median across the 941 utilities that report this is 185 minutes.
That is far worse than typical, and figures at this level almost always reflect a major storm season rather than everyday performance. A single hurricane or ice storm can dominate the annual number.
Optional rate plans
Green Mountain Power Corp offers time-of-use pricing and critical peak pricing to residential customers. 7,790 households were enrolled, about 3.4% of its residential base.
These plans are opt-in almost everywhere. They reward households that can move laundry, dishwashing, water heating or electric vehicle charging out of the late-afternoon peak, and they cost more than the standard rate for households that cannot. How to tell which group you are in.
Rooftop solar on this system
6,313 residential customers had net-metered solar in 2024, totalling 77.71 megawatts. That works out to 27.9 installations per thousand customers, against a median of 8 across the utilities reporting it.
Adoption is above the national median, which generally tracks the retail rate more closely than it tracks sunshine. What exports are actually worth.
