Houston electricity bills will increase starting September 1, 2025, when CenterPoint Energy’s seasonal delivery rate adjustment takes effect. A household using 1,000 kilowatt-hours will pay about $13 more per month as the delivery charge rises from approximately $49.50 to $62.50, depending on exact riders.
CenterPoint’s Houston Division tariff shows the per-kWh delivery charge increasing from about 4.46¢/kWh in August to approximately 5.76-5.81¢/kWh on September 1. For homes using 1,511 kWh, this means roughly $20.52 more each month ($72.15 rising to $92.67).
Your billing cycle can span the change; charges effective September 1 can apply to usage billed after that date. Check with your retail electric provider for your cycle rules.
The PUCT approves delivery charges twice yearly with updates typically effective March 1 and September 1 upon utility filings. These updates are seasonal; the March adjustment typically results in lower delivery rates heading into summer.

This September adjustment is separate from other recovery efforts. Separate from the seasonal adjustment, CenterPoint has proposed recovering 2024 derecho and Hurricane Beryl restoration costs via securitization; PUCT approval and bond issuance are pending, with bill impacts expected to start in early 2026 (about $2/month at 1,000 kWh under the proposal).
For those concerned about higher bills, adjusting thermostat settings helps. According to the U.S. Department of Energy, turning your thermostat back 7-10°F for eight hours a day can save up to about 10% per year on heating and cooling costs. A common practice is to raise the thermostat ~4°F when you’ll be away several hours; modest setbacks like this usually reduce cooling energy use. Keeping blinds closed during hot days reduces cooling needs.
