2026 Porsche Taycan 4 Performance Battery: home charging cost in Colorado

A 2026 Porsche Taycan 4 Performance Battery draws 38.6 kWh per 100 miles per the EPA; at Colorado's 16.65¢/kWh residential rate that's $6.42 per 100 miles charged at home, versus $16.02 for a 25.5-mpg gas car covering the same distance. Charging at home is much cheaper than gas here: 59.9% less than gas per mile, here specifically.

Annual cost, at 15 thousands miles a year

Driving 15,000 miles a year — fueleconomy.gov's own default assumption — a 2026 Porsche Taycan 4 Performance Battery charged at home in Colorado costs about $963/year in electricity, against about $2,403/year for the gas-car comparison. That's a savings of about $1,440 a year.

What one full charge costs

A 2026 Porsche Taycan 4 Performance Battery needs roughly 96.8 kWh to reach its EPA-rated 251-mile range, which runs about $16.12 at 16.65¢/kWh in Colorado.

Where this ranks

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 Colorado 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. At 16.65¢/kWh, Colorado sits in the middle of the national range — the guide to why charging cost varies by state shows where.
