UNDERSTANDING RATES AND TERMS OF SERVICE FOR ROCKY MOUNTAIN POWER ROOFTOP SOLAR CUSTOMERS

** If your electric utility is not Rocky Mountain Power, please contact your utility directly for applicable rates and terms of service.

HOW DO I KNOW WHAT KIND OF CUSTOMER I AM?

Net-Metered Customer

You are a Net Metered (NEM) customer if your complete interconnection application was submitted to Rocky Mountain Power before November 15, 2017.

You will remain within the current NEM program until December 31, 2035. Your energy generation and usage will be netted on a monthly basis. Excess generation will be carried to the next month and credited against that month’s usage until the end of the annualized billing period.
You will remain within your otherwise applicable customer class through December 31, 2035. (i.e. residential net-metered customers stay in the residential rate class)
Your rate structure will only change when changes apply to the entire rate class, including the actual rates and surcharges that change with Public Service Commission approval.
You will receive the current NEM program structure until December 31, 2035. Your monthly generation and usage will be netted. Excess generation will be carried to the next month and credited against that month’s usage until the end of the annualized billing period.
Excess generation credits expire at the end of the annualized billing period (March for most customer classes and October for the irrigator class)
The value of expiring credits will be applied to Rocky Mountain Power’s low income bill assistance program.
You retain RECs and all non-energy attributes.
You will no longer be considered a NEM customer if you
1. remove your approved rooftop solar generation system from service,
2. materially increase the size of your rooftop solar generation system, or
3. voluntarily change to another customer generation program.
If you sell your home or building, then you will lose the NEM customer status and the buyer of the property will become the NEM Customer.
You are required to participate in load research studies if selected to do so.
For all terms and conditions, see Schedule 135 .

Transition Customer

You are a Transition Customer if your complete interconnection application was submitted to Rocky Mountain Power after November 15, 2017 through October 30, 2020.

Your generation and consumption will be measured at 15 minute increments. If you consume more energy than you produce, you will pay for the actual amount of energy you consumed. If you produce more than you consume, you will be given a ¢/kWh credit for that excess energy.
Your compensation rate is based on your customer class or rate schedule and will be in effect until December 31, 2032.
1. Residential (Schedules 1, 2, or 3): 9.2 ¢/kWh
2. Schedule 6: 3.4¢/kWh

Excess generation credits expire at the end of the annualized billing period (March for most customer classes and October for the irrigator class)

You retain RECs and all non-energy attributes.
You will no longer be considered a Transition Customer if you
1. remove your approved rooftop solar generation system from service,
2. materially increase the size of your rooftop solar generation system, or
3. voluntarily change to another customer generation program.
If you sell your home or building, then you will lose Transition Customer status and the buyer of the property will become the Transition Customer.
You are required to participate in load research studies if selected to do so.
For all terms and conditions, see Schedule 136 .

Post-Transition / Export Credit Customer

You are a Post-Transition / Export Credit Customer if your complete interconnection application was submitted to Rocky Mountain Power after October 30, 2020.

Any customer-generated energy that is consumed on-site by the customer lowers that customer’s overall bills.
Exported Customer-Generated Energy means the amount of customer-generated energy in excess of the customer’s on-site consumption that is exported to the power grid.
The compensation rate for exported customer-generated energy will be updated annually around March 1st:
- As of March 1, 2022, for billing months June through September, you will be compensated 5.160¢ per kWh for all exported kWh.
- As of March 1, 2022, for billing months October through May, you will be compensated 4.462¢ per kWh for all exported kWh.
You will be charged for all energy consumed that isn’t offset by customer-generated energy based on the applicable standard service (i.e. if you are a residential customer, you will be billed at the rate of the residential electric service tariff on which you take service.)
Regardless of whether you export net generation during the month, you will be billed the minimum monthly amount from your applicable standard service tariff.
The credit value in dollars computed for the Exported Customer-Generated Energy will be applied against the Power and Energy Charges on the Customer’s monthly bill. Excess credits will carry-over to the next monthly bill during the Annualized Billing Period.
All unused credits accumulated by the customer-generator shall expire with the regularly scheduled meter reading at the conclusion of the Annualized Billing Period.

Be A Smart Shopper

Rooftop solar and other customer-sited generation may be a good choice for some consumers. Do your research and consider including the following analysis:

Carefully evaluate assumptions about the cost-benefit analysis, including financing options:

Research your electrical energy consumption and profile – each customer is different. Some people increase usage over time, others decrease usage, while some remain constant.
Scrutinize any assumptions or predictions about future utility rates. The Utah Public Service Commission keeps a history of rate changes that may be helpful.
Evaluate financing costs considering factors such as the payback period of the resource, the life of the resource, and the anticipated remaining time you plan to spend in your home.

Follow good consumer protection practices:

Always get estimates for the job from two or three contractors. If possible, find contractors who are recommended by a friend or family member who is familiar with the contractor’s work.
Get references from the contractor and then speak to the references. Discuss their satisfaction with the contractor’s work, whether the work was done on schedule and within the original contract price.
Check to make sure that the contractor has a business license from your city or local jurisdiction if required.
Ask the contractor about warranties available for their workmanship and warranties associated with the solar panels and inverters they plan to use.
Make sure the contractor agrees to the following in writing: the price, a summary of the work to be done and materials to be used, the day the work is to start and the estimated completion date, responsibility for clean up, any guarantees, and if applicable, the financing and credit terms, including payment schedules.
Read and understand all papers before you sign anything.
Please protect your Rocky Mountain Power account information to prevent fraudulent applications being submitted on your behalf.

Be wary of contractors who:

Quote or advertise a price, but then say it will cost more because it must be customized or the materials are out of stock.
Misrepresent the financing terms.
Only have a P.O. Box and/or answering service. Do not do business with a contractor that does not give out its business address or telephone number.
Say they have leftover materials from another job and can give you a discount.
Say that they will use your home as model to give you a special discount.
Come to your home seeking business, unless you are able to thoroughly check them out by verifying their contractor and business licenses and following the other tips outlined above.
Promise you a discount or commission if you supply names of other potential buyers.
Say they are working in the neighborhood and have extra time and materials to offer you a deal. That rarely turns out to be true.
