Weather and electricity in Corpus Christi
Typical weather near Corpus Christi, from the nearest NOAA station with a complete 1991-2020 record: Port Aransas 11 SSW, about 4 miles from the city center (station elevation 6 ft). These are normals for that station, not readings at your address. August is the warmest month on average, with a normal daily high of 91°F; January has the coolest average low, 49°F. Average daily highs reach 90°F or more in August. No month averages a daily low at or below freezing.
For electricity, the normals point to two seasons that can lift a household's usage: cooling-degree days (a measure of how far each day's mean temperature sits above 65°F) peak in August at 607 for the month, and heating-degree days (below 65°F) peak in January at 285. How much that matters to a bill depends on the home, its insulation, its heating fuel and the household, so use your own usage history, not a regional average, when you compare plans.

Historical weather records for Nueces County
The Texas Railroad Commission's county table lists a record low of 7°F (1899) and a record high of 113°F (1983), and a regional estimate of 18 consecutive hours as a typical longest freezing or frozen-precipitation period for Nueces County. These are historical county extremes, not Corpus Christi's monthly averages and not a forecast; the normals above describe ordinary months.
Reference only: the U.S. Energy Information Administration's 2020 Residential Energy Consumption Survey puts the average Texas household at about 13,440 kWh a year (about 1,120 kWh a month if spread evenly). That is a statewide average for 2020, not Corpus Christi, and not an estimate for your home. EIA source.

Business electricity in Corpus Christi
ERCOT lists 20,155 active business meters with a Corpus Christi address, about one for every 6.8 homes, and 78 meters in ERCOT’s large non-residential class across Corpus Christi’s main ZIP codes. On AEP Texas Central’s wires, a business picks its retail provider the same way a home does; larger accounts can also buy from suppliers that sell directly to commercial customers.
Power Hopper compares offers from retail electric providers and direct suppliers for businesses. For high-consumption businesses, we can run a competitive bid so more than one supplier prices the same usage. We can’t promise savings or how many suppliers will bid. Businesses in Texas retail-choice areas can request a rate review online.

Common questions
Can every address in Corpus Christi choose an electricity provider?
Most AEP Texas Central addresses can. Some Corpus Christi-addressed homes are on Nueces Electric Cooperative’s system, and co-ops serve rural areas around the city, so the exact service address decides. Enter your ZIP code, then your address, to see what is available.
How many homes in Corpus Christi have electric service on the competitive market?
ERCOT’s TDSP ESIID Extract lists 137,188 active residential electric meters (ESI IDs) with a Corpus Christi address (October 5, 2026), roughly one per home or apartment with a retail electricity provider.
Is Nueces Electric Cooperative part of the competitive market in Corpus Christi?
For the homes in ERCOT’s extract, yes: it lists 4,048 active residential meters with a Corpus Christi address on Nueces Electric Cooperative’s system and 133,140 on AEP Texas Central. The ZIP codes on this page are almost entirely AEP Texas Central. Co-op addresses outside the extract cannot choose, so check your service address.
Do the wires or the delivery utility change if I switch providers?
No. The delivery utility, AEP Texas Central, keeps the same wires and still delivers the electricity, and its delivery charges still appear on your bill. Switching changes the retail provider that bills you, not the wires.
