Status as of October 4, 2026. Rocky Mountain Power changes rates and program rules through filings with the Utah Public Service Commission. Everything here comes from the tariffs and program pages listed in the sources. Where the utility's marketing pages and its tariffs disagree, we follow the tariff.
Which Rocky Mountain Power EV programs are open now?
Four things are live for Utah customers: the optional Schedule 1 time-of-use rate, Wattsmart Drive managed-charging credits, Schedule 120 charger rebates for business and multifamily sites, and the utility's own public chargers. The residential charger rebate, the Schedule 2E EV pilot rate and the make-ready program have all ended.
| Program | Status | Who it is for |
|---|---|---|
| Schedule 1 time-of-use option | Open | Residential customers |
| Wattsmart Drive | Open | Customers who own or lease a supported EV |
| Schedule 120 charger rebates | Open | Businesses, workplaces, multifamily properties on a non-residential meter |
| Schedule 2E EV time-of-use pilot | Ended | Customers moved to the Schedule 1 option on or around December 1, 2025 |
| Residential Level 2 charger rebate | Ended | Removed from Schedule 120 effective January 1, 2026 |
| Make-ready incentives | Ended | Discontinued under the settlement approved December 29, 2025 |
Some third-party lists, including the federal AFDC laws database, still show the residential rebate and make-ready funding. Those listings are out of date.
How does the Schedule 1 time-of-use option work?
On-peak is 6 to 10 p.m., Monday through Friday, except holidays. Every other hour, including all weekend, is off-peak. Off-peak energy costs about a fifth of the on-peak price, so a home charger scheduled to start at 10 p.m. puts nearly all charging in the cheap window. The standard rate is tiered and does not change with the time of day.
| Schedule 1 time-of-use option | On-peak (6 to 10 p.m. weekdays) | Off-peak (all other hours) |
|---|---|---|
| June to September | 33.6173¢/kWh | 7.4705¢/kWh |
| October to May | 29.7498¢/kWh | 6.6111¢/kWh |
Energy charges from Schedule 1, filed August 5, 2026 and effective August 10, 2026. For comparison, the standard tiered energy charges are 9.8332¢ and 12.5263¢ per kWh in summer and 8.7020¢ and 11.0852¢ in winter.
- Commitment: one year minimum.
- Bill guarantee: a 12-month guarantee in the tariff. If the year costs more than 10 percent above the standard Schedule 1 rate, the utility credits the difference.
- Not compatible with Subscriber Solar (Schedule 73) or a non-standard meter.
- Enrollment: through your Rocky Mountain Power online account or by calling the utility.
Rocky Mountain Power's EV marketing page suggests charging after 10 p.m. or between 10 a.m. and 2 p.m. The tariff has no midday window, so set your charger schedule from the tariff hours. Time-of-use enrollment is no longer required for any of the utility's EV incentives.
What is Wattsmart Drive?
A managed-charging program for Utah customers who own or lease a supported EV. Rocky Mountain Power can pause charging during short high-demand events, and pays up to $100 for your first 12 months of enrollment and up to $50 for each additional 12 months, as an annual bill credit. It connects through your car's manufacturer account, so no new charger or meter is needed.
- No more than 48 events a year, most lasting up to 5 minutes.
- Two penalty-free opt-outs per program season; each extra opt-out reduces the credit by $10, never below $0.
- The season runs July through June, and credits typically appear on the August or September bill.
- The program page does not list supported vehicles; the enrollment portal checks your car.
What does Rocky Mountain Power pay business and multifamily sites?
Up to 75 percent of charger cost, with caps per charger: $1,000 for a single-port Level 2 charger and $1,500 for a dual-port unit, with larger amounts for DC fast chargers. The charger must be new, certified, bought on or after January 1, 2026, and installed behind a meter that is not on a residential rate. Funds are first-come, first-served.
| Charger | Single port, up to | Dual port, up to |
|---|---|---|
| AC Level 2 | $1,000 | $1,500 |
| DC fast, 150 kW or more per port | $30,000 | $42,000 |
| DC fast, under 150 kW per port | $15,000 | $21,000 |
Program page figures, 75 percent of charger cost up to the amount shown. Site caps are $60,000 per dealership location and $200,000 per other location. The page showed "over $1.5 million" remaining on October 4, 2026. Schedule 120 itself sets higher ceilings and says the website carries the current levels.
Level 2 applications go in after the charger is installed and energized, within one year of purchase, with a W-9, an itemized invoice and photos. DC fast chargers need pre-approval before purchase. Planning details are on our commercial EV charger installation, workplace EV charging and multifamily EV charging pages.
How do demand charges apply to charging sites?
Only on general service accounts. Schedule 23 is for small customers whose demand is at or under 30 kW in at least 7 of any 12 consecutive months and never above 35 kW; it bills power only above 15 kW. A customer that exceeds those limits moves to Schedule 6 for at least 12 months, where every kilowatt of the month's highest 15-minute demand is billed.
Under the August 10, 2026 tariffs, Schedule 23's power charge is $9.54 per kW from June to September and $8.44 from October to May, on kW above 15. Schedule 6 charges $14.49 and $12.82 per kW on all kW, plus a $4.36 per kW facilities charge. Schedule 6A is an energy time-of-day option with the same 6 to 10 p.m. weekday on-peak window. We found no EV-specific commercial rate in the Utah tariff list. Power sharing and load management are how sites keep chargers from setting the peak; see EV charger load management.
Do you have to tell Rocky Mountain Power before adding a charger?
If the charger needs a service or meter upgrade, yes: call 1-888-221-7070. Beyond that, Electric Service Regulation No. 5 asks for written notice before "any substantial additions or changes" to your electrical facilities, without defining substantial. Workplace and multifamily sites must give the utility the expected new load and charging frequency.
The full Regulation No. 5 sentence (section 2(b), effective April 25, 2025) reads: "Prior to the Customer making any substantial additions or changes in his/her electrical facilities, either in size or character, the Customer shall give the Company written notice of this fact." The utility can require a contract if the addition needs upgrades on its side. Its Electric Service Requirements manual, section 2.4, also asks customers to contact the company before adding load beyond what existed when service was set up, and names car chargers. Rocky Mountain Power's EV pages ask homeowners to call only when a service upgrade is needed; the tariff and manual wording is broader and does not say whether one home charger counts. The permit side is on our EV charger permits page.
What do Rocky Mountain Power's public chargers cost?
Schedule 60 sets prices at company-operated stations, including the eight fast chargers at Ogden's Union Station: $0.27 per kWh for Rocky Mountain Power customers and $0.45 for everyone else at DC fast chargers, $0.08 per kWh at Level 2, a $1.00 session fee, a $0.05 per kWh credit outside the 6 to 10 p.m. weekday peak, and $0.40 per minute after ten minutes at full charge. Where to plug in around town is on public EV charging in Ogden.
Rocky Mountain Power EV program questions
Does Rocky Mountain Power still give a rebate for a home EV charger?
No. The residential Level 2 charger rebate was removed from Schedule 120 effective January 1, 2026, after the Utah Public Service Commission approved a settlement. Some third-party listings, including the federal AFDC laws database, still show it. Households can still earn Wattsmart Drive bill credits and use the Schedule 1 time-of-use option.
Do I need the time-of-use rate to get a Rocky Mountain Power EV incentive?
No. The 2025 settlement removed time-of-use rates from Schedule 120's stated purpose because time-of-use enrollment is not a requirement for eligibility. The time-of-use option is worth choosing only if your household can keep most charging and other large loads out of the 6 to 10 p.m. weekday window.
What happened to Schedule 2E, the EV time-of-use pilot?
It was sunset. The tariff says that on or around December 1, 2025, customers on Schedule 2E transferred to the time-of-use option on Schedule 1. The Schedule 2E PDF still appears on Rocky Mountain Power's tariff page, which confuses some readers, but it is no longer an open rate.
Will Wattsmart Drive slow down my charging?
Only briefly. Rocky Mountain Power says there will be no more than 48 events a year, most lasting up to 5 minutes, and that the effect on a Level 2 charger is minimal. You can override any event from the program portal or your car's app; two overrides per season are free and each extra one takes $10 off the annual credit.
