2026 Cadillac OPTIQ AWD (19kW), ID Charging Cost

2026 Cadillac OPTIQ AWD (19 kW Charger): home charging cost in Idaho

In Idaho, home electricity runs 12.8¢/kWh, put a 2026 Cadillac OPTIQ AWD (19 kW Charger)'s EPA-rated 34 kWh/100mi against that and 100 miles costs $4.36, versus $16.02 for a gas car averaging 25.5 mpg.

Next step: home charger installation

The numbers above assume Level 2 home charging is already in place, the electrical work behind that is a real, separate cost that varies by panel, wiring, and local labor rates, not something this page's per-mile math includes.

Where these figures come from

Every figure on this page traces to a named EIA or EPA dataset, see the methodology guide. Idaho is one of the cheapest states for home electricity, the guide to why the cost varies so much by state covers what drives that.
