2026 Porsche Taycan 4 Perf Battery Plus 19in All-Season (M+S): home charging cost in Idaho

In Idaho, home electricity runs 12.8¢/kWh — put a 2026 Porsche Taycan 4 Perf Battery Plus 19in All-Season (M+S)'s EPA-rated 36.2 kWh/100mi against that and 100 miles costs $4.64, versus $16.02 for a gas car averaging 25.5 mpg. Charging at home costs a fraction of what gas would here: 71% less than gas per mile, here specifically.

What a year of driving costs

Driving 15,000 miles a year — fueleconomy.gov's own default assumption — a 2026 Porsche Taycan 4 Perf Battery Plus 19in All-Season (M+S) charged at home in Idaho costs about $696/year in electricity, against about $2,403/year for the gas-car comparison. That's a savings of about $1,707 a year.

What one full charge costs

A 2026 Porsche Taycan 4 Perf Battery Plus 19in All-Season (M+S) needs roughly 114.2 kWh to reach its EPA-rated 315-mile range, which runs about $14.61 at 12.8¢/kWh in Idaho.

Where this ranks

This combination ranks 2,964 of 20,400 state/model pairs for cost savings against gas (1 is cheapest). The Porsche Taycan 4 Perf Battery Plus 19in All-Season (M+S) alone ranks 172 of 400 models for efficiency; Idaho alone ranks 3 of 51 states for electricity price.

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.

Ask a licensed Idaho electrician to quote the install before this math becomes a real decision.

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.
