EV charging cost on Texas electricity plans

Driving 1,000 miles a month adds 246–494 kWh a month for the 15 model-year 2025 EVs we list (EPA combined figures from fueleconomy.gov, measured at the wall, so charging losses are included). The formula is miles × kWh per mile; for 500 miles a month, halve it.

As of Oct 9, 2026, for a 2025 Tesla Model Y Long Range AWD driven 1,000 miles a month (288 kWh), about $30.88–$33.98 a month (3.1–3.4¢ per mile) on the lowest-cost fixed-rate plan without a bill credit or minimum-usage fee in each of the 6 utilities. This is the plan’s 12-month estimate with the EV minus without it, for a home averaging 1,000 kWh a month, before taxes. Across all 15 vehicles the range is $26.36–$58.29 a month.

Bill-credit plans subtract a fixed credit in months when usage is above a threshold (often 1,000 kWh). A home that misses the threshold in mild months may reach it once EV charging is added, so the credit is paid in more months and the 12-month total can go down. The extra electricity is not free: the credit just applies more often. We show the difference on the same plan, with and without the EV, and the plain cost on plans without bill credits.

They can be, if most charging happens in their cheaper hours, and we estimate them separately in the time-of-use table above (not in the ranking), for the plans whose free hours are clearly stated in their Electricity Facts Label. On Oct 9, 2026, 26 of 47 time-of-use plans in the 6 utilities could be estimated.
