Current Texas electricity rates
As of May 2026, fixed-rate residential plans in Texas range from about 7¢ to 22¢ per kWh at 1,000 kWh usage. The middle 50% of plans fall between 12.8¢ and 15.3¢/kWh. Your effective rate depends on plan type, contract length, usage level, and whether the plan includes bill credits or minimum-usage fees.
Plans advertised at very low rates (under 10¢) often have bill credit structures that only deliver that price if you exceed a specific usage threshold. If your usage falls short, the effective rate jumps significantly. Read the Electricity Facts Label to see the rate at your actual usage level.
