Wyoming Electricity Rates
Rate data for Wyoming is being refreshed. The regulator and market facts below are current; figures return with the next data load.
Can you choose your electricity supplier in Wyoming?
No. Wyoming has not opened its residential electricity market to competition, so the utility that delivers your power also sells it. Its prices are set in rate cases before the Wyoming Public Service Commission, and the rate you pay depends on which utility serves your address, your rate schedule, and the season.
Grid operator: No RTO; Western bilateral market (WECC); SPP in the east. Wholesale power costs flow through to retail bills on the regulator's schedule rather than month to month, which is why regulated-state rates move more slowly than the market-based states listed below.

Wyoming's Public Service Commission regulates the rural electric cooperatives alongside Rocky Mountain Power and Black Hills Energy, so the same deposit cap (three highest months; refunded with interest after 12 on-time months at RMP, PRECorp and High West) and the November 1-April 30 personal-contact rule follow you to a co-op meter, yet the PSC cannot take complaints once you move inside a city like Cody or Powell that runs its own electric utility and sets its own deposits.
Who will deliver your power in Wyoming
The utility is fixed by your address. These are the largest in the state, with what each says it needs from a new customer.
Rocky Mountain Power (PacifiCorp)investor-owned
PacifiCorp's Wyoming division; its Wyoming tariff applies 'in all territory served by the Company in the State of Wyoming' and the company says it serves more than 1.2 million customers across Utah, Wyoming and Idaho combined (no Wyoming-only count or town list was published on the pages read). About more than 1.2 million across Utah, Wyoming and Idaho combined (per Rocky Mountain Power About page); Wyoming-only count not stated.
Start, stop and move requests go through the online My Account app and are 'processed within 1-2 business days or sooner' (customer-service FAQ). Under its PSC-approved Wyoming tariff Rule 9, a deposit may be required for initial service or if you have not had RMP service for 12 consecutive months in the past four years, or if you fail its credit screen; the deposit cannot exceed the estimated bill for the three highest-use months (or the estimated average 90-day bill if no history), earns interest at the PSC-authorized rate, and is credited back after 12 months of on-time payment; a written guarantor can substitute. Rule 3 says there is no charge to connect during normal business hours ($60 after hours per Schedule 300), and Rule 25 guarantees power switched on within 24 hours of the request when no construction or inspection is pending, with a $50 credit if missed. Standard residential Schedule 2 is a $23.00 monthly basic charge plus 8.136¢/kWh base; with riders the January 2026 Price Summary shows $24.24/month and 12.175¢/kWh combined.

Deposits, ID, and supplier choice in Wyoming
Deposits. The PSC-approved tariffs of Rocky Mountain Power, Cheyenne Light, Black Hills Power, PRECorp and High West all use the same cap: a deposit may not exceed the customer's estimated bill for the three highest-use months of the prior 12 (RMP falls back to an estimated average 90-day bill, Black Hills to the class average, PRECorp to a $350 minimum and High West to a $250 minimum when there is no billing history); Lower Valley Energy's fee schedule uses the same cap with a $200 minimum. RMP, PRECorp and High West pay simple interest at the Commission Authorized Interest Rate and credit the deposit back after 12 consecutive months of on-time payment. Municipal systems set their own: Cody $200 or $400 after a soft credit check, Powell $300 per electric meter. (rockymountainpower.net)
Choosing a supplier. There is no residential electricity supplier choice in Wyoming; each address is served by one PSC-certificated utility (or a municipal system), and the PSC's Choice Gas Program applies to natural gas, not electricity. The PSC's 2024 Electricity Profile shows all 17.2 million MWh of Wyoming retail sales as full-service provider sales and zero energy-only provider sales (EIA). https://psc.wyo.gov/home/choice-gas-program
The Wyoming PSC regulates cooperatives as well as investor-owned utilities (co-op dockets are numbered 10000-19999 and co-op tariffs are stamped by the Commission), but it cannot take complaints about municipalities providing electricity inside city limits. Complaints go to the PSC at (888) 570-9905 or wpsc_complaints@wyo.gov; the Office of Consumer Advocate, an independent division created in 2003, represents utility customers before the PSC in contested filings. Winter protections come from the tariffs: RMP, High West and PRECorp must attempt personal contact before disconnecting from November 1 through April 30, RMP will not disconnect when the forecast is below 32°F in the next 48 hours for a customer who cannot pay and is seeking assistance, and RMP gives 7 days' notice plus 15-30 extra days for documented medical conditions.

Programs that change what you pay
- Rooftop solar (net metering)available
- Wyoming statute W.S. 37-16-101 to 104 requires every electric utility (investor-owned, cooperative or irrigation district, but not municipalities) to offer net metering for customer solar, wind, biomass or hydro systems up to 25 kW; excess kWh roll forward as a credit to the next bill and any credit left at the start of each calendar year is bought out at the utility's filed avoided cost. Rocky Mountain Power implements this as Schedule 135 and Carbon Power & Light and High West post their own net-metering schedules.

- Time-of-use rateslimited
- Rocky Mountain Power's Schedule 19 Residential Time-of-Use Pilot is capped at 500 Wyoming customers first-come first-served, with on-peak 7-9 a.m. and 5-11 p.m. every day (16.092¢/kWh on-peak combined vs 12.175¢ standard), a $2 metering fee, a one-year commitment and a first-year guarantee refunding anything more than 10% above Schedule 2 costs. Several co-ops offer voluntary TOU too: High West's Residential Time of Day (8 hours on-peak), Carbon Power's A-TOD (16.4¢ winter on-peak / 6.96¢ off-peak) and PRECorp's seasonal Time-of-Use rate.

Questions people ask before moving to Wyoming
How far ahead should I set up electricity before moving to Wyoming?
Rocky Mountain Power processes start, stop and move requests within 1-2 business days, and its tariff guarantees power switched on within 24 hours of a request when no construction or inspection is pending. High West Energy warns it cannot guarantee same-day service or connections outside business hours (Monday-Thursday), so give any Wyoming utility at least a few business days, and in municipal towns such as Cody or Powell you apply through City Hall (Cody takes applications in person or online; Powell requires a notarized application and deposit, in person or by mail).

Can I choose my electricity supplier in Wyoming?
No. Wyoming has no retail electric choice; your address is served by one PSC-certificated utility (Rocky Mountain Power, Black Hills Energy or a cooperative) or a city-owned system, and EIA's 2024 profile records zero 'energy-only provider' sales in the state. The PSC's Choice Gas Program applies only to natural gas.
Sources: eia.gov, psc.wyo.gov, psc.wyo.gov
Will I have to pay a deposit for electricity in Wyoming?
Possibly: Rocky Mountain Power may require one for any initial service unless you pass its credit screen, and PSC-approved tariffs statewide cap the deposit at your estimated three highest months of bills (minimums of $350 at PRECorp, $250 at High West and $200 at Lower Valley when there is no billing history), returned with interest after 12 months of on-time payment at RMP, PRECorp and High West. City of Powell charges a flat $300 per electric meter and Cody $200 or $400 after a soft credit check; prepaid options at PRECorp and High West waive the deposit.

How much does electricity cost in Wyoming?
EIA puts Wyoming's all-sector average retail price at 9.14¢/kWh for 2024, 47th among states, and the residential average at 14.36¢/kWh in July 2026. Posted residential tariffs range from about 6.2¢/kWh plus demand and base charges at Lower Valley Energy to 12.175¢ plus $24.24/month at Rocky Mountain Power and $0.149/kWh plus $16.50/month at Cheyenne Light (Black Hills Energy).
Sources: eia.gov, eia.gov, lvenergy.com, rockymountainpower.net, blackhillsenergy.com
Can my power be shut off in a Wyoming winter if I fall behind?
There is no blanket statewide winter moratorium, but PSC-approved tariffs require Rocky Mountain Power, High West and PRECorp to attempt personal contact before any disconnection from November 1 through April 30, and Rocky Mountain Power will not disconnect a residential customer who cannot pay and is seeking assistance when temperatures are forecast below 32°F in the next 48 hours, nor from December 24 through January 2, on weekends or holidays, or while a payment plan is being kept. RMP gives seven days' notice plus 15 extra days for a documented serious illness and 30 for life-support equipment; LIEAP crisis assistance can also pay a shut-off notice.
Sources: rockymountainpower.net, highwest.coop, precorp.coop, dfs.wyo.gov
Where does Wyoming's electricity come from, and why are rates low?
EIA lists coal as Wyoming's primary electricity source; in 2024 the state generated 40.7 million MWh against 17.2 million MWh of in-state retail sales, and its 9.14¢/kWh average price ranked 47th. The downside is carbon intensity: Wyoming's power sector emitted 1,724 lbs of CO2 per MWh, third-highest in the nation.
