What that means for a Roy install
Roy's housing is mixed: about 42% predates 1980 and about 22% 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.
- Mid-century and 1970s Roy homes may need a load calculation. Many 1980s and 1990s homes have room for a 40- to 60-amp circuit.
- Military families on orders often prefer a NEMA 14-50 outlet with a portable charger, or a Wall Connector they can take with them.
- Roy 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 Roy accounts for about 8% of them.[2]
Charging costs on Rocky Mountain Power in Roy
Most Roy 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 Roy 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.
