Corpus Christi electric: competitive (deregulated) market

Corpus Christi is in Texas's deregulated electric market. AEP Texas Central is your transmission and distribution utility (TDU)—they deliver power and charge a regulated delivery fee ($3.24/mo + 5.9¢/kWh). You choose a Retail Electric Provider (REP) for supply; REP rates and plans vary.

Our estimated electric total above uses TDU delivery + average marketplace supply (~12.9¢/kWh total at 1,000 kWh). We do not update daily—rates change frequently. Actual bills depend on the plan you pick; current REP offers range from about 9¢ to 18¢/kWh (supply only). For an accurate estimate, compare current plans at Choose Texas Power or the state's Power to Choose for the latest rates.

FAQ

In Corpus Christi, electric is deregulated: you choose a retail electric provider (REP) for supply, while the transmission and distribution utility (TDU) delivers power. Our estimate uses regulated delivery charges plus a typical supply rate so you can compare total utility costs. Your actual supply rate depends on the plan you choose.
In Corpus Christi, sewer is billed in tiers based on usage, so the rate per gallon changes with volume. Our estimate uses the rate structure from City of Corpus Christi – Wastewater Rates (effective Jan 1, 2026) at the assumed 5,000 gallons per month. Your bill will vary with actual usage.
We use base charges and per-unit rates from official provider pages. Electric = base + (rate × assumed kWh). Water = base + (rate per 1,000 gal × assumed gallons / 1,000). Sewer is either a flat fee or a percentage of water. Trash is a fixed monthly fee. See the Methodology page for full formulas.
Actual bills depend on your usage, seasonal rates, taxes, fees, and provider-specific rules. Our estimates use fixed assumed usage (e.g., 1,000 kWh, 5,000 gal) for comparison. Your home may use more or less.
Each component shows a 'last verified' date. We aim to update from official sources periodically; always confirm current rates on the provider's site before making decisions.
