Washington home charging cost for the 2026 Porsche Macan GTS Electric

In Washington, home electricity runs 14.35¢/kWh — put a 2026 Porsche Macan GTS Electric's EPA-rated 36.7 kWh/100mi against that and 100 miles costs $5.27, versus $16.02 for a gas car averaging 25.5 mpg. Charging at home costs a fraction of what gas would here: 67.1% 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 GTS Electric costs roughly $790 a year to charge at home in Washington, against roughly $2,403 a year for an equivalent gas car. That's a savings of about $1,613 a year.

Cost of a full charge

Covering the 2026 Porsche Macan GTS Electric's EPA-rated 294-mile range takes about 107.9 kWh, which costs about $15.49 at Washington'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 5,850 of 20,400 state/model pairs for cost savings against gas (1 is cheapest). The Porsche Macan GTS Electric alone ranks 183 of 400 models for efficiency; Washington alone ranks 15 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 Washington electrician to quote the install before this math becomes a real decision.
