California home charging cost for the 2026 GMC SIERRA EV Ext Range (19kW Charger)

A 2026 GMC SIERRA EV Ext Range (19kW Charger) draws 52.4 kWh per 100 miles per the EPA; at California's 33.17¢/kWh residential rate that's $17.39 per 100 miles charged at home, versus $16.02 for a 25.5-mpg gas car covering the same distance. This model costs more to charge at home than gas would here: 8.5% more than gas per mile here, not less — the arithmetic isn't clamped to always favor charging.

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. This is one of the combinations where charging costs more than gas — the guide to when that happens explains why the arithmetic can go either way.
