2026 Tesla Model 3 Performance, RI Charging Cost

Rhode Island home charging cost for the 2026 Tesla Model 3 Performance

A 2026 Tesla Model 3 Performance draws 29.6 kWh per 100 miles per the EPA; at Rhode Island's 29.45¢/kWh residential rate that's $8.71 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: 45.6% less than gas per mile, here specifically.

What a year of driving costs

At fueleconomy.gov's default of 15,000 annual miles, the 2026 Tesla Model 3 Performance costs roughly $1,307 a year to charge at home in Rhode Island, against roughly $2,403 a year for an equivalent gas car. That's a savings of about $1,096 a year.

What one full charge costs

Covering the 2026 Tesla Model 3 Performance's EPA-rated 309-mile range takes about 91.4 kWh, which costs about $26.92 at Rhode Island'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 16,062 of 20,400 state/model pairs for cost savings against gas (1 is cheapest). The Tesla Model 3 Performance alone ranks 52 of 400 models for efficiency; Rhode Island alone ranks 47 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 Rhode Island 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. Rhode Island has some of the highest residential electricity rates in the country, see the guide to why the cost varies so much by state for the full picture.
