AEP Texas serves commercial customers across South Texas (Corpus Christi, Laredo, Harlingen) and parts of West/North Texas (Abilene, Vernon). Small-business tariffs typically energy-price around 5.4¢/kWh, with a demand charge that kicks in above 10 kW.
Regulated by the Public Utility Commission of Texas (PUCT). Tariff data sourced from URDB and verified against AEP Texas’s regulatory filings.
Covers Central + North divisions. Two URDB filings, one combined tariff structure. AEP Texas owns the poles, wires, transformers, and meters across South Texas (Corpus Christi, Laredo, Harlingen) and parts of West/North Texas (Abilene, Vernon). Whether or not you sign with a competitive REP, AEP Texas still bills the delivery side of your usage every month, and the rate schedule on file with the Public Utility Commission of Texas (PUCT) controls how those charges get calculated.
For a small business — defined as roughly under 10 kW of peak demand — the bill stays comparatively simple: a fixed customer charge, an energy charge per kWh, and the usual mix of riders and adjustments. Once you move past that threshold, the demand charge enters the picture, and managing your peak load becomes the largest single lever to cut your bill.
AEP Texas also moves commercial customers above roughly 700 kW onto time-of-use schedules. Peak hours in this territory typically run weekday afternoons, with the highest prices during the summer cooling season. If your operation can shift loads into off-peak windows — running heavy equipment at night or on weekends — you can cut the energy-charge portion of your bill noticeably without changing rate class.
Texas is a deregulated electricity market. AEP Texas is the wires utility (TDU) — it delivers power but doesn’t set the energy rate your business pays. The energy rate is sold separately by a retail electric provider (REP) in a competitive market. URDB only catalogs the regulated TDU pass-through schedules, which is why a meaningful “commercial tariff list” or “rate history” lives on the REP side, not here.

Most small businesses fall into one of three usage profiles. Match yours below to the tariff family that typically wins. If you’re on the boundary between two, the utility’s default tariff usually applies until you request a switch in writing.
Typical fit: GS-1 / G-1 / small general service. Energy-only billing, no demand charge, fixed monthly customer charge. This is the simplest commercial rate and where most sole-proprietor and storefront businesses land. Pair with a 12- or 24-month fixed contract from a Texas REP if you want predictability.
Typical fit: GS-2 / G-2 / medium general service. Demand charges enter the picture here, billed on your single highest 15-minute usage spike during the month. Audit your demand profile (most utilities will provide 15-minute interval data on request) and look for one-time peaks you can flatten — a single 8 PM equipment surge can drive a $200+/month charge.
Typical fit: large general service, GS-3, or primary service — usually with mandatory time-of-use pricing and sometimes a power-factor adjustment. At this size, hiring an energy broker or in-house manager pays for itself; a 1¢/kWh improvement on a million kWh a year is $10,000. REP offerings get custom-quoted at this load — published rates rarely apply.

URDB aggregates publicly filed tariffs from the Public Utility Commission of Texas (PUCT) and other state commissions. For source filings, see AEP Texas on OpenEI URDB . We sync URDB monthly and verify rate changes against each utility’s regulatory filings. Last updated June 9, 2026.
