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 Idaho 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 41663 kilowatt hours. A 944 kilowatt hour month against 1,207 kilowatt hours produced leaves 0 kilowatt hours billed and 263 banked for next month, so the energy charge falls from $135.65 to $0.00 at 14.37 cents per kilowatt hour.

Idaho average household use, 944 kWh a month, at the current published residential price of 14.37¢ 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.

Rocky Mountain Power requirementRequired

Battery backup is mandatory
in Rocky Mountain Power territory.

Rocky Mountain Power does not credit the power you send back at the rate it charges you to take it.

That does not make solar a bad idea in Rocky Mountain Power territory. It changes what you should build. When exports are worth a fraction of retail the credit stops being the return, and the job becomes using more of your own production inside the house, which usually means a larger array than a one for one utility would need.

Sizing is where that gets decided, so ask about it directly. Idaho Power pays about 4.27 cents for an exported kilowatt hour after its 2024 move to net billing, a 31% cut, so the value of an Idaho system now sits in what the house consumes as it is produced. Rocky Mountain Power sets its own limits. Ask Rocky Mountain Power what it allows before you accept that a bigger system is off the table.

A battery then does two separate jobs. It moves daytime production into the evening so you use it instead of selling it, and it keeps the house running when the grid goes down. That second job is not a bonus. Panels on their own shut off in an outage, by design, so a roof full of them powers nothing during a storm. That is the part we will not refer around.

So we treat it as a requirement, not an upgrade. We will not refer you for a panels-only system in Rocky Mountain Power territory, and you should be skeptical of anyone who quotes you one without raising storage first.

Our referral policy, not a legal or utility requirement

What your installer should be telling you

The export credit rate varies by season and time of day and is revised through the Commission. Ask Rocky Mountain Power for the current figures in writing before you sign.

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
$25.00 a month
How it is set
Rocky Mountain Power’s Idaho residential service carries a Customer Charge of $25.00 a month, among the higher fixed charges on this site and well above the $12.00 the same company charges a single-family home in Utah. The optional time-of-day schedule, Schedule 36, is $26.50. Energy above the charge is seasonal: from June to October 12.0214 cents a kilowatt hour for the first 700 and 13.8140 cents above that, and from November to May 10.2638 cents for the first 1,000 and 11.7577 cents above, each figure already including the riders the price summary combines into the effective rate. A seasonal customer is billed differently again, with a $300.00 annual minimum. Read the $25.00 against what a system can save here: at around 12 cents a kilowatt hour, it takes about 200 kilowatt hours of displaced use every month just to equal the fixed charge you will pay regardless.

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.

There is no statewide net metering policy
The Commission has required investor owned utilities to offer net metering through separate docket proceedings rather than under a single state rule, and has since moved Rocky Mountain Power and Idaho Power onto net billing.
Older systems keep net metering until October 2045
The Commission ruled in October 2020 that customers already on Schedule 135, Net Metering Service, stay on it for 25 years. That service ends on 2 October 2045, after which those customers move to net billing.
Ask which docket governs your utility
Because Idaho legislated nothing, the rules are in a Commission order specific to your company. There is no state statute to fall back on if you disagree with a quote.

Rocky Mountain Power net metering questions

Does Rocky Mountain Power offer one for one net metering?
No. Rocky Mountain Power bills Idaho rooftop solar under Schedule 136, Net Billing Service: you pay the retail rate for what you draw from the grid and are credited at an export credit rate for what you send back. Customers already on the older Schedule 135 net metering keep it until 2 October 2045.
What does Rocky Mountain Power pay for power sent back to the grid?
Net billing, with a seasonal export rate. Export credits are applied against the bill under Schedule 136.
Do I need a battery with Rocky Mountain Power?
Yes, and we treat it as mandatory. Because Rocky Mountain Power does not credit exports one for one, the return has to come from using your own production rather than selling it, which after dark means storage and usually a larger array than a one for one utility would need. The other half is backup: panels alone shut off in an outage, so a battery is what keeps the house running in a storm. We do not refer panels-only systems in Rocky Mountain Power territory. This is our referral policy, not a legal or utility requirement.
How do I find my Rocky Mountain Power bill?

What is the catch with Rocky Mountain Power?
