Energy companies in Corpus Christi: who sells your power, and the LNG, refining and plant operators behind the economy

This report is for Corpus Christi residents and businesses working out who to buy electricity from, for job seekers looking at the Coastal Bend's energy employers, and for B2B sellers whose customers are plants, terminals and the contractors that serve them.

Who sells you electricity in Corpus Christi

Start with the name on your bill or meter. EIA's 2025 utility survey (Form EIA-861) lists four electric utilities with territory in Nueces and San Patricio counties:

NRG's 2025 10-K explains the rule behind the "no" rows: competitive retail serves most of the ERCOT grid except areas, served by city utilities and co-ops, that haven't opted into competition. AEP Texas Central delivered power to 929,438 customers across its territory in 2025.

If you're on AEP lines, three things keep a provider choice honest:

• Read the Electricity Facts Label. Under the Public Utility Commission's rule (16 TAC §25.475), it gives the average price at 500, 1,000 and 2,000 kWh, says whether the price is fixed or variable, and states the term and any cancellation fee. Use the line nearest your usage.
• Watch the renewal date. For a fixed-rate plan the provider must send at least three written notices before it expires, which gives you time to compare.
• Know where complaints go. Contact the provider, then the commission's Consumer Protection Division. In 2025, Nueces County customers filed 69 complaints about 20 different REPs and 12 about AEP Texas Central; San Patricio County added 13 about 9 REPs.

The state consumer advocate, the Office of Public Utility Counsel, points shoppers to the commission's Power to Choose website (powertochoose.org) for offers by ZIP code.

The energy industry in Census data

County Business Patterns 2023 counts electric power, oil and gas extraction and pipeline establishments (NAICS 2211, 211 and 486) in the Corpus Christi, TX Metro Area (CBSA 18580):

The Census Bureau flagged the employee and payroll totals as high-noise (noise added for confidentiality changed them by 5% or more), because of the pipeline segment. By segment:

Nueces County has 73 of the establishments and San Patricio County 13; those county rows add to 86, two short of the metro total, as published. County employee counts are high-noise figures. CBP counts establishments with paid employees, not companies, and leaves out the self-employed.

The bigger employers sit outside these three codes. The same Census file shows three petroleum refineries in the metro (NAICS 324110) with 2,338 employees and average pay of $174,523, and 89 oil and gas support contractors (NAICS 213112) with 1,802 employees. If you're job hunting, those two lines matter as much as the energy total.

LNG and the port

Cheniere Energy's 2025 10-K describes its Corpus Christi LNG Terminal as having over 30 mtpa (million tonnes a year) of expected production capacity, including over 9 mtpa under construction at the end of 2025. Its Stage 3 project adds seven midscale trains, the first four substantially complete by year end, and the company approved two more trains in June 2025, with Bechtel as contractor. EIA's Texas profile notes the terminal began operating in 2019 and nearly doubled its export capacity in early 2025.

The Port of Corpus Christi, which calls itself the third largest US port by total waterborne tonnage, reported a record 162.7 million tons in the first nine months of 2026. Third-quarter volumes included 30.4 million tons of crude oil and 6.6 million tons of LNG, up 46.2%.

Power plants

EIA's 2025 generator survey (Form EIA-860) lists 25 plants in the metro with 5,479 MW of capacity, run by 19 operators: 64.4% natural gas, 27.6% wind, 3.5% batteries and 3.2% solar.

The wind fleet is mostly in San Patricio County, where RWE Clean Energy runs the Papalote Creek and El Algodon Alto farms.

Public companies and local lists

No SEC-listed company in these industries has a Corpus Christi-area address on EDGAR; the big operators are run from elsewhere, Cheniere from Houston and CPS Energy from San Antonio. For named local employers, the Corpus Christi Regional Economic Development Corporation's top-companies list for the Coastal Bend (data as of March 2026) includes AEP Texas and Flint Hills Resources, alongside industrial firms Turner Industries Group, MMR Group, Bay Ltd. and Kiewit Offshore Services.

Selling to Coastal Bend energy operators

This is a market of a few large sites, so buying runs through plant maintenance and turnaround planning, not a long list of small accounts.

Illustrative example. The seller and its rates are invented; plant and refinery counts are from EIA-860 and Census.

Baffin Bay Hydroblast (baffinbay.example) cleans heat exchangers and boiler tubes. EIA-860 lists eight gas-fired plants of 40 MW or more in the metro, run by seven operators, including cogeneration units at a refinery and two chemical plants; Census adds three refineries. That's roughly ten sites. With a maintenance manager and a turnaround planner at each, about 20 contacts. One booked job per planned outage season is the realistic goal, so research the outage calendar and the plant's last cleaning before you write. Bebop can pull that account research together for each site and draft the first email; the guide to finding decision makers covers who to look for.

Subject: [plant name] exchanger cleaning before [outage season]

Hi [first name],

[Plant name] runs [number] units at [capacity] MW, and planned outages on the coast tend to bunch up in [season].

We hydroblast heat exchangers and boiler tubes with a crew based in [town], so you're not paying for travel from Houston. We can quote from your last inspection report.

Is there a planner I should send a quote template to for [season]?

[Your name]
