Green Mountain Power commercial electricity prices, 2015 to 2025

In 2015 Green Mountain Power billed its commercial customers an average of 14.33¢ per kWh. In 2025 the figure was 20.38¢, so it rose 42% over 10 years. The average for all commercial customers in Vermont rose 36% over the same period. The latest year, 2025, is the highest of the 11 on record here. Between 2024 and 2025 it rose 5.9%.

Average use and average bill are the utility’s commercial sales and revenue divided by its commercial customers and by twelve. The bill is an all-in figure: energy, delivery, demand and fixed charges together. A few very large customers pull both averages up, so most businesses use and pay less than the average.

Residential, commercial and industrial prices at Green Mountain Power

In 2025 the average commercial price at Green Mountain Power was 12% below the residential figure and 78% above the industrial one. Larger customers take power at a higher voltage and use it more steadily, so at most utilities the average falls from residential to commercial to industrial. Which class an account falls in is the utility’s decision, and the line between commercial and industrial is drawn differently from one utility to the next.

How Green Mountain Power’s commercial rates are set

Green Mountain Power is investor-owned, so its rates are set in cases before the Vermont Public Utility Commission and published in a tariff, which is a public document. A commercial account is billed on a rate schedule, chosen by the size of the account and the voltage it takes power at, and a schedule usually combines a fixed monthly charge, a charge per kWh and, above a certain size, a demand charge on the highest rate of draw in the month. The schedule code is printed on the bill. There is no competitive supply market for ordinary commercial accounts in Vermont, so the levers are the schedule, the peak and the amount used.

Meters, time-varying rates and net metering at Green Mountain Power

EIA counts 48,520 commercial meters at Green Mountain Power in 2025, and 47,944 of them (99%) are advanced meters (AMI), which record use at least hourly and report it to the utility at least daily. Of the rest, 576 are standard meters. An advanced meter is what makes interval data possible, and interval data is what shows when a building’s peak demand happens.

At Green Mountain Power, 3,640 commercial customers were on a time-varying rate in 2025, about 7.4% of its commercial customers. A time-varying rate charges more in some hours than in others, so when a business uses power matters as well as how much. The kinds Green Mountain Power reports offering commercial customers are time-of-use pricing, critical peak pricing and critical peak rebate pricing.

EIA records 587 commercial net-metered generating systems at Green Mountain Power in 2025, with 61.2 MW of capacity between them: about 12 for every 1,000 commercial customers. Net metering credits a customer for power its own system sends to the grid; the terms are in the utility’s tariff.

How reliable is Green Mountain Power’s electric service?

Green Mountain Power customers went without power for an average of 190 minutes in 2025, excluding major storms, with about 1.58 interruptions per customer. The average across U.S. utilities reporting the same way is 124 minutes. With major storms counted the figure was 265 minutes. This utility reports on a different measurement standard, so the comparison is only approximate. These are averages over every customer of every class, so they describe the system and not any one street.

Where Green Mountain Power serves

EIA records Green Mountain Power serving customers in 13 Vermont counties: Addison, Bennington, Caledonia, Chittenden, Essex, Franklin, Lamoille, Orange, Orleans, Rutland, Washington, Windham, Windsor. A county can be shared between utilities, so this does not tell you who serves a given address. The utility that serves an address is the one named on its bill.

EIA lists ISO New England as its balancing authority. ISO New England is one of the organised wholesale markets, which run the grid and the wholesale power market across their area.

Other utilities in Vermont

No other Vermont utility has a page of its own here. The Vermont page lists every utility EIA records in the state with 500 or more commercial customers.

What these figures can and cannot tell you

• They are averages over every commercial customer. A utility whose commercial customers are mostly large averages fewer cents per kWh than one serving mostly small shops, so a lower figure can mean larger customers and not a lower rate.
• They are not a rate schedule. None of these figures is a charge printed in Green Mountain Power’s tariff, and nothing here works out a bill from one. The tariff index lists the utilities whose filed schedules are quoted on this site.
• They are annual and final. EIA publishes utility figures once a year. The Vermont page carries the state’s trailing 12 months, which is more recent and still preliminary.

For one building, the cost estimator gives a range by building type, size and state, and price by utility sets every utility side by side. Commercial vs residential vs industrial compares the classes in every state.
