Charging a 2025 Tesla Model 3 Long Range RWD at home in Texas
Updated Oct 9, 2026
Power to Choose data imported · refreshed daily
Charging a 2025 Tesla Model 3 Long Range RWD 1,000 miles a month adds about 246 kWh a month (EPA combined 24.6 kWh/100 mi, measured at the wall).
On the lowest-cost fixed-rate plan without a bill credit or minimum-usage fee in each of the 6 Texas utilities, that’s about $26.36–$29.03 a month (2.6–2.9¢ per mile) — our estimate, before taxes, October 2026.
For a home averaging 1,000 kWh a month plus this EV, the lowest-cost fixed-rate plan in each utility comes to about $136.58–$147.03 a month in total.
In 1 of 6 utilities that lowest-cost plan is a bill-credit plan whose estimate is lower with the EV than without, because the extra kWh reach its credit threshold in more months — that is the credit, not free charging.

“EV charging” = the plan’s 12-month estimate with the EV minus the same plan without the EV. On bill-credit plans this can be zero or negative: the EV’s extra kWh push more months over the credit threshold, so the plan’s credit is paid in more months. That is the credit, not free charging — the same household might pay less on another plan without the EV. Plans without a bill credit or minimum-usage fee show the plain cost of the extra kWh.

Time-of-use and free-nights plans
Time-of-use plans (free nights, free weekends and similar) may be cheaper if you charge during their cheaper hours, but we have not yet estimated EV charging on them, so they are listed here without a cost. On Oct 9, 2026, 47 such plans were listed in the 6 utilities. Check each plan’s EFL for its hours and prices.
EV kWh per month = miles per month × kWh per mile ÷ charging efficiency. Vehicle figures are the EPA combined consumption from fueleconomy.gov (U.S. EPA and DOE), retrieved Oct 9, 2026, which is measured at the wall and already includes charging losses, so the charging efficiency is 1.0. With your own kWh per mile (a vehicle-side figure) we divide by 0.90.
The same EV kWh is added to every month (no seasonal driving pattern), and all charging is at home on the household’s plan. The home uses a typical Texas seasonal pattern (more in summer).
Plans are ranked on home + EV usage with our usual method: fixed-rate plans of 6 months or longer, bill credits applied only in months that qualify, Power to Choose prices including delivery charges, taxes not included. Estimates, not offers — check the EFL before you sign. How it works →
Not included: time-of-use pricing for EV charging, public charging, and any comparison with gasoline (we do not collect gasoline prices).

Frequently asked questions
How much electricity does a 2025 Tesla Model 3 Long Range RWD use per month?
About 246 kWh for 1,000 miles a month, from its EPA combined consumption of 24.6 kWh per 100 miles (fueleconomy.gov), which is measured at the wall and includes charging losses. 500 miles: about 123 kWh; 1,500 miles: about 370 kWh.
How much does it cost to charge a 2025 Tesla Model 3 Long Range RWD at home in Texas?
As of Oct 9, 2026, about $26.36–$29.03 a month for 1,000 miles (2.6–2.9¢ per mile) on the lowest-cost fixed-rate plan without a bill credit or minimum-usage fee in each of the 6 Texas utilities, for a home averaging 1,000 kWh a month. TexasHomeBills™ estimate: the plan’s 12-month cost with the EV minus without, before taxes.
Why is the EV cost negative on some plans?
Bill-credit plans subtract a fixed credit in months when usage is above a threshold. EV charging can push more months over it, so the credit is paid more often and the 12-month total can fall. The extra electricity is not free; the credit just applies more often.
