2026 Porsche Macan Electric, ID Charging Cost

Idaho home charging cost for the 2026 Porsche Macan Electric

In Idaho, home electricity runs 12.8¢/kWh, put a 2026 Porsche Macan Electric's EPA-rated 34.6 kWh/100mi against that and 100 miles costs $4.43, versus $16.02 for a gas car averaging 25.5 mpg. Charging at home costs a fraction of what gas would here: 72.4% less than gas per mile, here specifically.

Annual cost, at 15 thousands miles a year

At fueleconomy.gov's default of 15,000 annual miles, the 2026 Porsche Macan Electric costs roughly $664 a year to charge at home in Idaho, against roughly $2,403 a year for an equivalent gas car. That's a savings of about $1,739 a year.

What one full charge costs

Covering the 2026 Porsche Macan Electric's EPA-rated 309-mile range takes about 106.9 kWh, which costs about $13.68 at Idaho's residential rate, figured from the EPA's own combined range and consumption numbers, not the pack's nameplate capacity.

Where this ranks

This combination ranks 2,126 of 20,400 state/model pairs for cost savings against gas (1 is cheapest). The Porsche Macan Electric alone ranks 139 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.

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.
