Published terms

Under Schedule 135, a month of net use is billed at the energy charge of your standard schedule. When the system makes more than Rocky Mountain Power supplies, you pay the monthly charges and the net energy becomes a kilowatt hour credit on the next bill. Credit left at the start of each calendar year is bought at the Schedule 37 rate for unused net metering credits: for fixed solar, 1.418 cents a kWh for 2026 and 1.358 cents for 2027 (1.545 and 1.647 cents for tracking solar).

Month to month
Kilowatt hour credits carry from month to month through the calendar year.
Once a year

Installers serving Rocky Mountain Power customers

Pick one. Only the company you choose receives your details, and only that company calls you.

Not sure which to choose?

These are real companies operating in Rocky Mountain Power territory, ordered by reviews, years trading and BBB grade. None of them pays us for placement. Pick the one you want and we will call you to arrange it.

Ordering combines three things we read from primary sources: Google review count and rating, years trading taken from the company’s Better Business Bureau profile rather than its own marketing, and its BBB letter grade. BBB accreditation is shown but never scored, because it is a paid membership rather than a mark of quality.

Check any contractor license yourself at the state register. Do that before you sign anything, with any company, including ours.

What this looks like on a Rocky Mountain Power bill

An average Wyoming household, against a system sized to cover its year. The energy charge is the part that goes to zero. The fixed monthly charge underneath it is the part that never does, and it is the number that decides whether a system pays for itself.

Meter reading falling from 41926 to 41685 kilowatt hours. A 863 kilowatt hour month against 1,104 kilowatt hours produced leaves 0 kilowatt hours billed and 241 banked for next month, so the energy charge falls from $131.52 to $0.00 at 15.24 cents per kilowatt hour.

Wyoming average household use, 863 kWh a month, at the current published residential price of 15.24¢ per kWh. Your utility still bills a fixed monthly customer charge that no system offsets, so this is the energy part of the bill, which is the part that goes away.

What your installer should be telling you

Size to what the house uses in a year: a kilowatt hour left in January is bought at about 1.4 cents. The system must be 25 kW or less.

What Rocky Mountain Power bills you anyway

In a month when your production covers everything you use, the energy charge can reach zero. This does not. It is the floor under every bill, and it is the number that decides whether a system pays for itself.

The charge
$24.24 a month once the riders on it are added
How it is set
Schedule 2, Residential Service, sets a base Basic Charge of $23.00 for single-phase service and $30.00 for three-phase, and the riders that ride on it are not all per kilowatt hour. Rider Schedule 92, the Insurance Cost Adjustment, adds a flat $0.53; Rider Schedule 191, the Customer Efficiency Service Charge, adds 2.98 percent; and Rider Schedule 198, the Carbon Capture, Utilization, and Storage Charge that Wyoming law requires, adds 0.05 percent. The two percentages are struck on the basic charge as well as the energy, so the combined fixed charge on a single-phase house is $24.24, and $31.46 on three phase. Rocky Mountain Power’s own price summary says it “does not include any local taxes or fees”, so a municipal franchise fee where you live sits on top of $24.24 again. Energy is 11.515 cents a kilowatt hour combined, all year, with no seasonal tiers. Do not read the Utah figures across: the same company charges a Utah single-family home $12.00, half of this.

Applying to Rocky Mountain Power

What Rocky Mountain Power itself requires, as distinct from what the state rule requires. Read from its own published guidelines on the date shown.

25 kilowatts per system, and no cap on the program
Wyo. Stat. § 37-16-101 defines a net metering system as one of not more than 25 kW, and the statute sets no limit on how many customers may net meter.
Municipal systems are excluded
The statute reaches investor owned utilities, cooperatives and irrigation districts, but not municipalities. If your bill comes from a town, ask what it offers rather than what the state requires.
January buys the leftover at avoided cost
At the beginning of each calendar year, unused kilowatt hour credit from the previous year is sold to the utility at its filed avoided cost, a small fraction of what the same kilowatt hour costs to buy.
25 kW binds a ranch long before it binds a house
For an ordinary home it is ample. For agricultural or small commercial load it is frequently the number that decides the design, so check it first.

Rocky Mountain Power net metering questions

Does Rocky Mountain Power offer one for one net metering?
Yes. Under Schedule 135, a month of net use is billed at the energy charge of your standard schedule. When the system makes more than Rocky Mountain Power supplies, you pay the monthly charges and the net energy becomes a kilowatt hour credit on the next bill. Credit left at the start of each calendar year is bought at the Schedule 37 rate for unused net metering credits: for fixed solar, 1.418 cents a kWh for 2026 and 1.358 cents for 2027 (1.545 and 1.647 cents for tracking solar). Kilowatt hour credits carry from month to month through the calendar year.
What does Rocky Mountain Power pay for power sent back to the grid?
Carried forward in kWh, surplus sold each January at about 1.4 cents. At the beginning of each calendar year, remaining credit is sold to Rocky Mountain Power at the Schedule 37 unused credit rate for your technology.
Do I need a battery with Rocky Mountain Power?
Not for the economics. Rocky Mountain Power credits exports at the retail rate, so power you send out during the day comes back at the same value after dark without storage. A battery is still worth considering for outages during hurricane season, but it is an upgrade here rather than a requirement.
How do I find my Rocky Mountain Power bill?
Sign in at rockymountainpower.net. Open My Account, then Billing. Open the latest bill and save the PDF. Or screenshot the summary page. If you cannot get to it, a rough guess at your average monthly amount is enough to start.
What is the catch with Rocky Mountain Power?
Size to what the house uses in a year: a kilowatt hour left in January is bought at about 1.4 cents. The system must be 25 kW or less.
