Questions homeowners ask
Is every Utah solar account on the same arrangement?
Rocky Mountain Power lists Utah Schedule 135 grandfathered net metering and Schedule 136 transition service as closed to new applicants, separately from Schedule 137 net billing. Record your accepted schedule.

Does installation completion authorize operation?
The utility process separates review, permitting, installation, inspection and meter installation. It says not to turn the system on during installation and that the utility will notify you when operation is allowed.

Which installed-capacity basis does Schedule 137 define?
Schedule 137 uses DC nameplate capacity, with a 25 kW residential limit and additional eligibility conditions.

What counts as exported customer-generated energy?
It is generation beyond on-site consumption that reaches the grid, rather than total inverter production.

Are consumption charges and export credits the same calculation?
No. Consumption uses the standard service tariff; exports receive separate seasonal credit rates.

Can export credits eliminate every monthly obligation?
No. Minimum and other charges remain. Export dollars offset power and energy charges; excess carries within the annualized period.

When does the residential annualized period end?
It ends at the scheduled March meter reading. New accounts begin at service start; Schedule 10 has a different period.

Do unused Schedule 137 credits remain indefinitely?
No. Unused credits expire at the meter reading concluding the annualized period.

How should I compare a proposal with my account records?
Keep the accepted generation schedule, standard service schedule, applicable document dates, labeled capacity, production assumptions and monthly import/export estimates together. Ask the installer to identify each assumed credit and the utility to confirm account treatment. Mark missing evidence unknown. Do not treat a favorable example as a guaranteed bill.
What can Solar Survey AI help document?
Our education and evidence methodology help identify missing inputs behind a proposal. A defined site survey may document accessible site conditions; confirm homeowner scope, availability, commercial relationships and limits before booking. The utility controls interconnection and billing. Homeowner provider connections and planned free remote diagnosis remain coming soon.
Your decision checklist
- Verify the property’s actual utility and Utah service.
- Retain both generation and standard service schedules.
- Label capacity with its DC or AC basis.
- Separate production, on-site use and exported energy.
- Use the account’s applicable dated credit-rate sheet.
- Keep minimum and other charges in a comparison.
- Record the March meter-reading boundary and unused credits.
- Obtain written utility operating authorization.

Trace the schedule, period and remaining charges
| Record | Evidence to retain |
|---|---|
| Accepted service | Utah generation schedule and standard tariff |
| Capacity | Equipment rating, units and accepted application |
| Energy | Production, on-site use, import and export definitions |
| Credit calculation | Rate-sheet effective date and billing month |
| Annual boundary | Actual March reading and credit-expiration explanation |
| Operating status | Separate inspection, meter and utility authorization records |
Illustration only: an invented export record shows 120 kWh and an invented credit rate of $0.04 per kWh, giving $4.80. These figures are not Rocky Mountain Power rates or customer results. A dollar credit is not 120 kWh available to offset any later month, and the example does not calculate remaining charges or savings.
Example: a homeowner assumes the credit year ends March 31, but their statement has a different scheduled March meter-reading date. Ask the utility to identify the account’s annualized boundary and show how unused credit is handled. Preserve its written response with the statement rather than substituting a calendar-month assumption.
This guide concerns selected Rocky Mountain Power Utah Schedule 137 records, not every Utah utility, Idaho or Wyoming service, or legacy Schedule 135/136 billing. The reviewed tariff combines sheets effective April 25, 2025 with a revised credit-rate sheet effective March 1, 2026. Confirm the currently applicable filed tariff and account terms before acting; we do not publish sample values as utility prices. Our worksheet and examples are editorial advice. Read bill measurement guidance, separate approval milestones and proposal and finance records. Explore Solar Survey AI’s evidence methodology and confirm available survey scope.
