Laredo is one of the most important international trade cities in the United States — the largest inland port of entry on the US-Mexico border, processing over $200 billion in annual trade through its bridges over the Rio Grande. With a population over 270,000, Laredo is Webb County's seat and the dominant city of South Texas's western corridor. It also has one of the most extreme climates of any large American city, with summer temperatures that regularly reach 104–110°F. For electricity purposes, Laredo's extreme heat makes plan comparison more consequential — and the advertised 1,000 kWh rate more misleading — than virtually anywhere else in Texas.
The short answer
Laredo ZIP codes 78040–78046 are AEP Texas Central territory — fully deregulated. Fixed-rate plans as of May 2026 advertise 10.0–14.5¢/kWh at 1,000 kWh. Extreme summer heat drives typical usage of 1,500–2,300 kWh in July and August — far above the 1,000 kWh benchmark. The 2,000 kWh EFL tier is the only meaningful plan comparison point for most Laredo households. Enter your ZIP and bedroom count for the true interpolated cost.
AEP Texas Central in Laredo
AEP Texas Central serves Laredo and all of Webb County as the regulated TDU. Its TDSP charges — a fixed customer fee and per-kWh distribution charge regulated by the PUCT — appear on every Laredo bill regardless of REP. At 1,000 kWh, these charges typically total $11–$16. At 2,000 kWh in peak summer, they rise to $19–$26.
The competitive plan market in Laredo ZIP codes typically offers 40–70 plans from 12–18 providers. While smaller than Houston's market, the variation between plans at high usage levels is meaningful — comparing at 2,000 kWh rather than 1,000 kWh can reveal a $25–$50/month difference between plans that appear nearly identical at the advertised rate.
Laredo's Extreme Heat — The Usage Driver
| Month | Avg High (°F) | Typical 3BR Usage | All-In Bill Est. |
|---|---|---|---|
| June | 101°F | 1,400–1,800 kWh | $175–$235 |
| July | 105°F | 1,700–2,200 kWh | $215–$280 |
| August | 107°F | 1,800–2,300 kWh | $225–$295 |
| September | 99°F | 1,400–1,900 kWh | $175–$245 |
A Texas example
Miguel lives in a 1,600 sq ft home in north Laredo (78045). August usage: 1,970 kWh. His plan was advertised at 11.5¢/kWh at 1,000 kWh. Expected bill: ~$115 energy. Actual August bill: $258.72. At 1,970 kWh the interpolated rate was 10.55¢/kWh, energy charge $207.84. AEP TDSP added $25, taxes $12, and a $9.95 base charge completed the total. A plan comparison showed a plan with the same 1,000 kWh advertised rate but 9.1¢/kWh at 2,000 kWh — at 1,970 kWh, that plan would have cost $223.80, saving Miguel $34.92/month. Over four peak months: $139.68 saved.
Dry Heat vs. Humid Heat — Why Laredo Is Different
Unlike Houston or Beaumont, Laredo's summer heat is relatively dry — relative humidity in summer afternoons often drops to 25–35%. Dry heat feels less oppressive to humans, but it does not make buildings easier to cool. In fact, dry extreme heat produces intense radiant heat gain — the sun bakes walls, roofs, and concrete to temperatures well above 120°F, driving heat into the building through conduction even with AC running. HVAC systems in Laredo fight both ambient air temperature and radiant heat gain simultaneously.
The practical result: HVAC systems in Laredo run at very high duty cycles during peak summer — often 80–90% of the time during the hottest August afternoons. Any HVAC system that is undersized, poorly maintained, or losing refrigerant charge will fail to maintain comfort and will run continuously without achieving setpoint — the electricity equivalent of money leaking out of the building all day.
Watch out
In Laredo's extreme heat, a failing HVAC system is a medical emergency, not an inconvenience. AC failure during a 107°F August day can create indoor temperatures of 120°F+ within hours. Do not wait until the AC fails to address aging equipment. If your system is 10+ years old and struggling to maintain setpoint during the hottest days, have it inspected before the next summer season. Early replacement is far less costly than emergency replacement in August at peak season pricing — and the lower electricity usage of a newer high-efficiency system compounds as savings over every subsequent summer.
Smart move
Laredo's extreme solar irradiance makes radiant heat gain through windows and roofs one of the highest electricity cost drivers in the home. Reflective roofing (cool roof coatings) and exterior window shading on south and west exposures can reduce summer cooling load by 15–25% — significantly more than in temperate climates. A cool roof coating on a flat or low-slope Laredo home typically pays for itself in 3–5 years through reduced electricity bills, with the ROI accelerating on any plan with a meaningful rate at high usage levels.
Key Takeaways
Laredo ZIP codes 78040–78046 are AEP Texas Central territory — delivery charges are fixed. Extreme summer heat drives usage of 1,500–2,300 kWh, making the 2,000 kWh EFL tier the only relevant comparison point. Plan comparison can yield $100–$140 in summer savings. Low-income assistance is available through Webb County Community Action. HVAC maintenance before summer is a non-negotiable in one of the hottest cities in America.

Why does Laredo have some of the highest electricity bills in Texas?
Laredo has a continental climate with extremely dry, intense heat — summer temperatures regularly exceed 104–108°F from June through September. Unlike coastal cities that benefit from Gulf breezes, Laredo's inland location offers no temperature relief. The combination of extreme heat, low humidity (which the body's cooling system handles better but buildings handle poorly with radiant heat), and a long cooling season makes Laredo electricity bills among the highest per household in Texas.
How many electricity plans are available in Laredo?
Laredo ZIP codes typically have 40–70 active plans from 12–18 retail electric providers — a somewhat smaller market than Houston but with meaningful competition, especially at high usage levels. Enter your ZIP on the search tool for the current ranked list at your usage level.
Is there electricity assistance available in Laredo?
Yes. LIHEAP (Low Income Home Energy Assistance Program) and CEAP (Comprehensive Energy Assistance Program) provide bill assistance to income-eligible households. Contact the Webb County Community Action Agency or the Texas Department of Housing and Community Affairs for current program details. Laredo has one of the higher poverty rates of major Texas cities, making these programs widely relevant.
