What that means for a Marriott-Slaterville install
Marriott-Slaterville's housing is mixed: about 29% predates 1980 and about 38% is 2000 or newer. So whether you need a panel upgrade really is a home-by-home question, and a quick load calculation answers it.
- Rural parcels here can mean a long distance between the meter, the panel and where the car parks. Measure it, because distance drives wire size and cost.
- Newer subdivision homes are typically straightforward garage installs.
- Marriott-Slaterville is Rocky Mountain Power territory, so the Schedule 1 time-of-use option is available to most homes.
Across Weber County, 3,378 battery-electric vehicles were registered as of February 2026, and Marriott-Slaterville accounts for about 2% of them.[2]
Charging costs on Rocky Mountain Power in Marriott-Slaterville
Most Marriott-Slaterville homes are Rocky Mountain Power customers. RMP's Schedule 1 time-of-use option treats only 6 to 10 p.m. on non-holiday weekdays as on-peak. Off-peak base energy is 6.6111¢ per kWh from October through May and 7.4705¢ from June through September, versus on-peak prices of 29.7498¢ and 33.6173¢.[3] Surcharges and taxes are extra, and the rate applies to your whole home, so it pays off when you can keep big loads out of the evening window.
RMP's Wattsmart Drive program, run through your car maker's app for supported brands, pays up to $100 in bill credits the first year and up to $50 each following year in exchange for letting RMP briefly manage charging.[4] There is no RMP rebate for the home charger itself in 2026.[5] If your bill isn't from Rocky Mountain Power, these programs won't apply.
Permits and inspection
The electrician pulls the electrical permit through Marriott-Slaterville City's building process, and the work is inspected before it's energized. Utah adopted the 2023 National Electrical Code effective July 1, 2025, and most one- and two-family homes follow the electrical provisions of the International Residential Code as amended by Utah.[6][7] Current code requires GFCI protection for many EV outlets; your electrician will confirm exactly what your install needs.

Marriott-Slaterville EV charger FAQ
Why does distance matter so much?
Longer runs need heavier wire to limit voltage drop, plus more trenching or conduit, so cost grows with every foot.
Can you serve Marriott-Slaterville addresses with an Ogden mailing address?
Yes. We go by where the home is, not the mailing city.
Is there an EV charger rebate in Marriott-Slaterville in 2026?
There's no utility rebate for a home charger right now. Rocky Mountain Power removed its residential charger rebate effective Jan. 1, 2026, and the federal 30C credit ended for chargers placed in service after June 30, 2026. See our 2026 rebate guide for what's still available.
