Yes. On San Diego Community Power's average rate with SDG&E delivery, charging an EV costs the same per mile as gas at $3.49 a gallon. Gas in the San Diego area averaged $6.33 on October 12, 2026, so 1,000 miles a month costs about $129 to charge versus $235 in gas: roughly $105 a month back.
Your electric utility sets what charging costs, so here are the numbers for each one serving San Diego.
Serves most homes in San Diego, Chula Vista and other member cities, with SDG&E delivering the power
Average home rate 43.1 cents per kWh (SDG&E delivery plus San Diego Community Power, 2025). Charging costs the same per mile as gas at $3.49 a gallon: about $129 for 1,000 miles versus $235 in gas.
SDG&E still delivers the power. Its EV programs are on the SDG&E card; ask SDG&E whether they cover San Diego Community Power customers.
Serves homes that buy their power straight from SDG&E

Gas prices jumped in 2026 when the war with Iran disrupted oil shipping through the Strait of Hormuz. Home electricity is priced by utilities under state regulators and moves far more slowly, so the gap tends to widen when gas spikes. For a 27 mpg car to cost less per mile than charging at home in San Diego, gas would have to fall below $3.49 a gallon.

We assume 1,000 miles a month, a typical new EV that uses 30 kWh per 100 miles, a 27 mpg gas car, and home charging at each utility's average residential rate, which includes its fixed monthly charges. An overnight or EV rate is often cheaper than that average, and public fast charging costs much more. Treat this as the honest average, not your bill.

Yes. Charging at home on San Diego Community Power (43.1 cents per kWh, SDG&E delivery plus San Diego Community Power, 2025) costs about $129 per 1,000 miles. The same miles in a 27 mpg car cost about $235 at the $6.33 San Diego gas average on October 12, 2026. California's $121/yr EV fee still leaves about $1,143 a year in your favor.
About $3.49 to $3.71 a gallon, depending on your utility: $3.49 on San Diego Community Power and $3.71 on SDG&E. That is what a 27 mpg car would need to pay to match the cost per mile of charging at home.
At home, about $129 per 1,000 miles on San Diego Community Power (43.1 cents per kWh) or $137 per 1,000 miles on SDG&E (45.8 cents per kWh), for a typical EV that uses 30 kWh per 100 miles. Public fast charging costs much more per kWh than home charging, so these numbers assume you charge at home most of the time.
