Which utility serves Wyoming, and what does it charge?
The 8 largest utilities selling to Wyoming 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 |
|---|---|---|---|---|---|
| PacifiCorp | Investor-owned | 118,130 (41.2%) | 13.44¢ | 739 kWh | 940 (0.80%) |
| Cheyenne Light Fuel & Power | Investor-owned | 39,954 (14.0%) | 16.96¢ | 583 kWh | 1,171 (2.9%) |
| Lower Valley Energy | Co-op | 22,827 (8.0%) | 6.44¢ | 2,010 kWh | 122 (0.53%) |
| Powder River Energy Corporation | Co-op | 15,406 (5.4%) | 11.73¢ | 1,138 kWh | 113 (0.73%) |
| Montana-Dakota Utilities Company | Investor-owned | 14,706 (5.1%) | 11.77¢ | 849 kWh | 169 (1.2%) |

Each Wyoming 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 Wyoming utility figures mean for a solar quote?
EIA-861 lists 12 utilities serving homes in Wyoming in 2024, across 286,475 residential accounts. The three largest, PacifiCorp, Cheyenne Light Fuel & Power and Lower Valley Energy, served 63.2% of those homes. By ownership: investor-owned utilities 61.1%, electric cooperatives 20.1%, small utilities EIA counts as a group 13.9% and municipal utilities 4.9%.
All 286,475 Wyoming residential accounts bought energy from the utility that delivers it; EIA counted none on a competitive supplier. So a Wyoming utility’s own tariff sets both the price you avoid and the credit for what you export.
PacifiCorp, the largest, served 118,130 Wyoming homes (41.2%). Its full-service residential customers paid 13.44¢ per kWh, above the Wyoming average of 12.47¢, and used 739 kWh a month on average. 940 of its customers ran net-metered rooftop solar, 0.80% of its homes against 1.02% statewide.
Among the 8 Wyoming utilities with at least 5,000 residential customers and a full-service price, the price ran from 6.44¢ at Lower Valley Energy to 16.96¢ at Cheyenne Light Fuel & Power.
At the Wyoming average of 10,361 kWh a year, that 10.52¢ gap is worth about $1,090 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 12.47¢ Wyoming average.
Rooftop solar is concentrated: Cheyenne Light Fuel & Power alone accounts for 1,171 net-metered residential systems, about 40% of the 2,913 counted in Wyoming, and 9 Wyoming utilities reported any at all. The highest adoption among the larger utilities was at High West Energy, where 4.3% of homes had a system.
What does power cost in Wyoming, and why does it matter?
Residential electricity in Wyoming averaged 12.47¢ per kilowatt-hour in 2024, the 10th-lowest of 51 and below the national 16.48¢. Retail power in Wyoming is cheaper than in 41 of the other 50 jurisdictions. Each kilowatt-hour a system avoids is worth less, which lengthens payback.
The average Wyoming household bill was $107.65 a month ($1,292 a year), the 4th-lowest of 51, against $142.26 nationally. That $1,292 is the ceiling on what solar could save a typical Wyoming home, before fixed monthly charges.
Only 0.61% of Wyoming homes were on a time-varying rate in 2024 (11.1% nationally), so a flat rate is the likely starting point. 39.3% of Wyoming residential meters were smart meters (83.8% nationally), and a time-varying rate needs one. How time-of-use changes solar.
How many Wyoming homes have solar?
Wyoming had 2,913 rooftop systems on net metering in 2024, across 286,475 residential accounts: 1.02% of homes, the 18th-lowest of 51. Adoption in Wyoming sits in the middle of the 51: neither an early market nor a late one.
The Wyoming market counted 570 more systems in 2024 than in 2023 and has grown 26.4% a year over five years, the 23rd-highest of 51. Where growth has turned nationally.
How has Wyoming solar changed since 2014?
Wyoming counted 211 net-metered rooftop systems in 2014 and 2,913 in 2024, 13.8 times as many. The share of homes with one moved from 0.08% to 1.02%. The biggest one-year addition came in 2024, with 570 more systems than the year before.
| Year | Rooftop systems | Share of homes | Average size | Residential price |
|---|---|---|---|---|
| 2014 | 211 | 0.08% | 4.8 kW | 10.50¢ |
| 2016 | 301 | 0.11% | 5.1 kW | 11.13¢ |
| 2018 | 582 | 0.21% | 5.6 kW | 11.29¢ |
| 2020 | 1,143 | 0.41% | 6.0 kW | 11.11¢ |
| 2022 | 1,946 | 0.69% | 6.6 kW | 11.09¢ |
| 2024 | 2,913 | 1.02% | 6.4 kW | 12.47¢ |

What does the Wyoming trend mean for a savings estimate?
Over the same years the Wyoming residential price went from 10.50¢ to 12.47¢ per kWh, up 19%, and the average system from 4.8 kW to 6.4 kW. With Wyoming prices up 19% across ten years, a savings estimate that assumes steep yearly rate rises is assuming more than this record shows.
How big is a typical Wyoming system?
The average Wyoming system was 6.36 kW in 2024, the 12th-lowest of 51, against 6.74 kW nationally. Wyoming homes used 10,361 kilowatt-hours a year each, the 24th-lowest of 51.
A Wyoming home using 10,361 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 Wyoming?
Form EIA-861 reports no third-party-ownership split for the 2,913 systems counted in Wyoming in 2024, so we publish none rather than infer one.
Ask any Wyoming company in writing whether it is selling you the system or a lease or power purchase agreement; the owner of a Wyoming system is the one who claims any tax credit.
Do Wyoming homes add batteries?
In Wyoming, 4.09% of solar systems were paired with a battery in 2024 (119 systems), the 12th-highest of 47. Wyoming’s share is below the national 5.86%.
On reliability, the average Wyoming customer went 138 minutes without power in 2024 counting major storms, and 116 minutes without them. The median state saw 297. Outages in every state.
Whether a battery pays in Wyoming 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 Wyoming?
We found no dedicated state register for solar work in Wyoming, 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 2,913 systems in Wyoming, 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.
Which states are closest to Wyoming on adoption?

Where do the Wyoming numbers come from?
The Wyoming figures are HyreSolar calculations from the Form EIA-861 annual files: 2,913 net-metered residential systems counted against 286,475 residential accounts, sizes as means, and 12 utility-level rows for the utility table, matched to net-metering records by EIA utility number.
The method and limits cover all 51; the Wyoming row is in the data as a CSV.
No Wyoming 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.
