Which utility serves Vermont, and what does it charge?
The 3 largest utilities selling to Vermont homes, by residential customers, with the price full-service customers paid and how many run net-metered solar.
| Utility | Type | Homes served | Price per kWh | Use per home, monthly | Net-metered systems |
|---|---|---|---|---|---|
| Green Mountain Power Corporation | Investor-owned | 226,675 (70.9%) | 22.09¢ | 586 kWh | 6,313 (2.8%) |
| Vermont Electric Cooperative | Co-op | 35,964 (11.3%) | 23.26¢ | 558 kWh | 2,553 (7.1%) |
| City of Burlington Electric | Municipal | 17,861 (5.6%) | 18.88¢ | 420 kWh | 327 (1.8%) |
Source: US EIA, Form EIA-861 2024, Sales to Ultimate Customers and Net Metering, utility level, retrieved 5 October 2026. Shares are of 319,656 Vermont residential accounts. Each Vermont price is residential revenue divided by sales for full-service customers (HyreSolar calculation); a wires company’s price is its default-service price.
What do the Vermont utility figures mean for a solar quote?
EIA-861 lists 3 utilities serving homes in Vermont in 2024, across 319,656 residential accounts. The three largest, Green Mountain Power Corporation, Vermont Electric Cooperative and City of Burlington Electric, served 87.8% of those homes. By ownership: investor-owned utilities 70.9%, small utilities EIA counts as a group 12.2%, electric cooperatives 11.3% and municipal utilities 5.6%.
All 319,656 Vermont residential accounts bought energy from the utility that delivers it; EIA counted none on a competitive supplier. So a Vermont utility’s own tariff sets both the price you avoid and the credit for what you export.
Green Mountain Power Corporation, the largest, served 226,675 Vermont homes (70.9%). Its full-service residential customers paid 22.09¢ per kWh, above the Vermont average of 21.90¢, and used 586 kWh a month on average. 6,313 of its customers ran net-metered rooftop solar, 2.8% of its homes against 2.84% statewide.
Among the 3 Vermont utilities with at least 5,000 residential customers and a full-service price, the price ran from 18.88¢ at City of Burlington Electric to 23.26¢ at Vermont Electric Cooperative.
At the Vermont average of 6,884 kWh a year, that 4.38¢ gap is worth about $302 a year (our arithmetic), so the same system offsets more money in one territory than the other.
Price a quote on your own utility’s rate, not the 21.90¢ Vermont average.
Rooftop solar is concentrated: Green Mountain Power Corporation alone accounts for 6,313 net-metered residential systems, about 69% of the 9,193 counted in Vermont, and 3 Vermont utilities reported any at all. The highest adoption among the larger utilities was at Vermont Electric Cooperative, where 7.1% of homes had a system.
What does power cost in Vermont, and why does it matter?
Residential electricity in Vermont averaged 21.90¢ per kilowatt-hour in 2024, the 10th-highest of 51 and above the national 16.48¢. Vermont sits in the top quarter on price, so power used on site replaces power bought at well above the national rate.
The average Vermont household bill was $125.66 a month ($1,508 a year), the 17th-lowest of 51, against $142.26 nationally. That $1,508 is the ceiling on what solar could save a typical Vermont home, before fixed monthly charges.
Only 2.5% of Vermont homes were on a time-varying rate in 2024 (11.1% nationally), so a flat rate is the likely starting point. 78.1% of Vermont residential meters were smart meters (83.8% nationally), and a time-varying rate needs one. How time-of-use changes solar.
How many Vermont homes have solar?
Vermont had 9,193 rooftop systems on net metering in 2024, across 323,960 residential accounts: 2.84% of homes, the 17th-highest of 51. Adoption in Vermont sits above the middle of the 51, so there is a working installer market to choose between.
The Vermont market counted 664 fewer systems in 2024 than in 2023 and has grown 1.5% a year over five years, the lowest of 51. Where growth has turned nationally.
How has Vermont solar changed since 2014?
Vermont counted 3,649 net-metered rooftop systems in 2014 and 9,193 in 2024, 2.5 times as many. The share of homes with one moved from 1.17% to 2.84%. The biggest one-year addition came in 2015, with 1,566 more systems than the year before.
| Year | Rooftop systems | Share of homes | Average size | Residential price |
|---|---|---|---|---|
| 2014 | 3,649 | 1.17% | 6.6 kW | 17.47¢ |
| 2016 | 6,020 | 1.93% | 7.9 kW | 17.37¢ |
| 2018 | 7,746 | 2.46% | 8.5 kW | 18.02¢ |
| 2020 | 8,350 | 2.63% | 9.4 kW | 19.54¢ |
| 2022 | 9,472 | 2.95% | 10.3 kW | 19.93¢ |
| 2024 | 9,193 | 2.84% | 10.9 kW | 21.90¢ |

What does the Vermont trend mean for a savings estimate?
Over the same years the Vermont residential price went from 17.47¢ to 21.90¢ per kWh, up 25%, and the average system from 6.6 kW to 10.9 kW. A rate that has risen that far makes a 2024 bill a conservative base for a Vermont savings estimate only if the trend continues, which nobody can promise.
How big is a typical Vermont system?
The average Vermont system was 10.9 kW in 2024, the 3rd-highest of 51, against 6.74 kW nationally. Vermont homes used 6,884 kilowatt-hours a year each, the 7th-lowest of 51.
A Vermont home using 6,884 kWh is an average, not a design input: size from your own twelve months of bills and usable roof with cost by system size and the system size calculator.
Who owns the systems in Vermont?
In Vermont, 49.0% of systems were third-party owned in 2024: leased, or on a power purchase agreement (PPA), rather than owned by the household. That is the 5th-highest of 38, against 29.1% nationally.
Third-party ownership is the common way solar is sold in Vermont. Expect a lease or power purchase agreement to be offered, and check who will own the equipment before you sign. Whoever owns a Vermont system claims any tax credit on it: Section 48E explained.
Do Vermont homes add batteries?
Form EIA-861 recorded no battery-paired figure for Vermont’s 9,193 systems in 2024, so we cannot give an attachment rate.
On reliability, the average Vermont customer went 896 minutes without power in 2024 counting major storms, and 232 minutes without them. The median state saw 297. Outages in every state.
Whether storage pays in Vermont turns on your utility’s export credit and your own outage history: what a home battery does.
How do you check a solar company’s license in Vermont?
We found no dedicated state register for solar work in Vermont, so we publish no company counts. That is not evidence of light regulation: electrical work can be licensed at state or local level even where solar is never named.
With 9,193 systems in Vermont, the company quoting you may be based out of state. Ask which license it holds, in which state, and confirm it with that authority. What to do when the search comes back empty.

Where do the Vermont numbers come from?
The Vermont figures are HyreSolar calculations from the Form EIA-861 annual files: 9,193 net-metered residential systems counted against 323,960 residential accounts, sizes as means, and 3 utility-level rows for the utility table, matched to net-metering records by EIA utility number.
The method and limits cover all 51; the Vermont row is in the data as a CSV.
No Vermont figure here is an estimate for one home: your roof, usage, utility tariff and tax position decide that.

Primary-source research, data analysis and fact checking
We are a research desk, not a sales floor. We read the statute, the tariff, the code section, the federal filing or the manufacturer data sheet ourselves, and we publish the figure with the document it came from and the date we retrieved it.
Where a number cannot be traced to a primary source, we publish the shorter page and say what we could not verify. That rule has cost us whole sections, and it is why the rest can be checked.

How this desk works
- Primary sources only. Statutes from the legislature’s own publishing system, federal data from the agency that collects it, code text from the adopted edition, manufacturer claims from the data sheet. We do not cite an article that cites a source; we go and read the source.
- Every figure carries its provenance. A named document and the date we retrieved it, so you can check it and so you know how old it is. Retrieval dates are not decoration: an EIA rate from May is a different fact from an EIA rate from August.
- We publish what we could not verify. Every research page carries a section naming the things we tried to establish and could not, and why. A paywalled standard, a state website that refused the request, a manufacturer that publishes no figure at all.
- We separate measurement from modeling from our own reasoning, and label which is which on the page. A laboratory measurement, an assumption inside a modeling tool and our own inference are three different kinds of claim and they are never presented as one.
- We do not sell solar, and we take no payment for placement, ranking or a favorable mention. Nobody buys a position on this site.
Data as of EIA-861 2024 final release. Authorship on this site is organizational: the analysis belongs to the desk rather than to a named individual, and we do not publish credentials we do not hold. Our editorial policy sets out how we source, date and correct what we publish.
