Moving to Corpus Christi: setting up electricity

First, confirm the address has retail choice

Corpus Christi is in the ERCOT region, in an area where customers of investor-owned utilities have been able to choose a retail electric provider since January 1, 2002. Some Texas addresses are served by municipally owned utilities or electric cooperatives that have not opted into retail choice, or sit outside ERCOT. The PUCT’s Power to Choose site can indicate whether a ZIP is in an area open to competition. See the deregulation guide for official sources.

Moving to Corpus Christi: local notes

Corpus Christi ZIP codes from 78401 downtown to 78418 on Flour Bluff and Padre Island, plus 78410 in Calallen, showed competitive offers on Power to Choose on November 14, 2026. A few edge-of-city addresses are served by an electric cooperative, so confirm your exact address.

Many people arrive on military orders for Naval Air Station Corpus Christi, to study at Texas A&M University–Corpus Christi, or for work at the port and refineries. If your move-in date is set, you can pick a retail electric provider ahead of time and choose a start date on the official enrollment page.

If you expect another move within a year or two, compare contract terms and early termination fees carefully, and keep proof of your forwarding address — Texas rules limit early termination fees when you move.

A move-in is not the same as a switch

A switch changes retail providers at a premise that already has service. A move-in establishes service for a customer at a premise, identified by an electric service identifier (ESI ID). Under 16 TAC §25.474, a retail electric provider must submit a move-in or switch request to the registration agent — in ERCOT, that role is described in official materials as ERCOT — so it can be processed on the approximate scheduled date agreed to by the applicant and allowed by the utility’s tariff.

The same rule’s right of rescission — three federal business days after you receive the Terms of Service, without penalty — applies to switch requests. The rule states that the right of rescission is not applicable to an applicant requesting a move-in.

16 TAC §25.487 describes the standard move-in: the retail electric provider submits the move-in transaction electronically, in accordance with applicable protocols, to establish service for a new customer. The local transmission and distribution utility connects service at the premise.

Practical steps official rules point you toward

1. Choose a retail electric provider if the address is in a competitive area. Compare offers using the Electricity Facts Label, Terms of Service, and Your Rights as a Customer, as described in the plan-choice guide.
2. Have your new service address and the date you need service. If you have the ESI ID — often printed on a prior bill for that premise — have that available too.
3. Complete enrollment with the provider so it can submit the move-in for your requested date, consistent with the utility’s tariff. Start early enough for that process to run before you need the lights on. This site does not publish a specific number of days, because official rules point to the agreed date and the tariff rather than a single statewide lead time.
4. After service starts, the local utility still delivers power, reads the meter, and handles outages. For an outage, use the instructions on your electric bill or the utility’s website.

If you are leaving another Texas competitive-choice address, §25.475 says a contract is limited to the location specified in it. If you move and provide a forwarding address and, if required, reasonable evidence that you no longer occupy that location, no early termination fee may be assessed as a result of the relocation.

Home battery backup after you move

If you own an eligible single-family home, official Think+ materials may also offer a home battery backup program at that address. Not every home qualifies. See the battery program page and the eligibility checklist.
