AEP Texas Central commercial electricity
AEP Texas Central provides regulated delivery service. Supply is contracted separately in competitive territory.
AEP Texas Central is the TDU serving Coastal and south Texas, including the Corpus Christi and Rio Grande Valley areas. It delivers power, owns the meter and restores outages under regulated tariffs. Eligible commercial accounts contract the supply portion separately. Accounts are keyed on ESI ID.

Competitive supply market. Delivery, demand and fixed charges on an AEP Texas Central account remain regulated regardless of which supplier you choose.
What the U.S. government data says about AEP Texas Central
EIA’s 2025 utility sales table has no commercial sales rows for AEP Texas. So there is no utility-level figure to show here. The Texas figures, from the same source, are on the Texas page.

Cities and areas in this territory
Territory boundaries do not follow city limits. Two addresses on the same street can sit in different territories, which is why we confirm the ESI ID rather than inferring eligibility from the city or the ZIP code. Inferring from location is the most common way a commercial account is told it can do something it cannot.

Which lever moves which charge
This is the question a utility page exists to answer. If you change something at the meter, which line on the bill actually moves — and which one does not move no matter what you do?
Schematic shapes, not AEP Texas Central's actual rates — those come from the filed tariff. The point is the behaviour: two of these four respond to something you control, and a supplier changes none of them.
What sits inside the delivery charge from AEP Texas Central
Delivery is not one number. On a commercial account it is typically assembled from several components, each set by the filed tariff and each behaving differently as your usage changes:
- A fixed customer or meter charge, which does not move with consumption at all.
- A volumetric distribution charge per kWh, which scales with how much you use.
- A demand charge per kW where the account is demand-metered, which scales with how hard you draw rather than how much you use — and which is where a low load factor account gets hurt.
- Riders and surcharges, adjusted periodically through regulatory filings, covering items such as transmission cost recovery, energy efficiency programs and storm or system restoration costs.
None of these changes when you change supplier. Understanding the mix matters because it determines which action actually moves your bill: reducing consumption attacks the volumetric component, reducing peak draw attacks the demand component, and neither one touches the fixed charge.
The other territories in Texas
Boundaries do not follow city limits. If you are not certain which of these serves your address, confirm the ESI ID printed on the bill rather than inferring it from the city.
What the AEP Texas Central tariff says: Secondary Voltage Service Greater Than 10 kW (with Secondary Voltage Service Less Than or Equal to 10 kW)
Read 2026-10-30 from AEP Texas Tariff for Retail Delivery Service, Chapter 6 Section 6.1.1 (Revision: First), Effective Date: Bills Rendered on or after October 1, 2024. Each figure is quoted from that document, and it is a schedule figure, not a bill estimate. See every tariff quoted on this site. The tariff and the schedule code on your bill control what applies to you.
- Who the over-10 kW schedule covers
- Secondary Voltage Service Greater Than 10 kW is for non-residential delivery at secondary voltage with demand greater than 10 kW, to one point of delivery measured through one meter. Standard service is single-phase, 60 hertz; three-phase may be provided where qualifying motors are permanently installed and in regular use, or at the company's sole discretion.
- Fixed monthly charges
- Customer Charge $2.28 per Retail Customer per Month and Metering Charge $19.72 per Retail Customer per Month.
- Distribution System Charge
- The Distribution System Charge is $7.148 per NCP kW Billing Demand. The NCP kW Billing Demand is the kW supplied during the 15-minute period of maximum use. On this schedule the 80% ratchet is stated only for the TC, NDC, SRC and ADFIT riders.
- Transmission System Charge line
- The schedules print the Transmission System Charge as $0.00 (over 10 kW: $0.00 per NCP kW Metered Demand and $0.00 per 4CP kW Metered Demand; 10 kW or less: $0.00 per kWh) and list the Transmission Cost Recovery Factor as See Rider TCRF. Over 10 kW, premises that have established an NCP kW of at least 700 kW in any previous billing month, or were billed on 4CP kW before the tariff took effect, are billed on 4CP kW.
- Billed separately
- Transition Charge, nuclear decommissioning, transmission cost recovery, competitive metering credit, energy efficiency, distribution cost recovery, income tax refund, system restoration, ADFIT credit, regulatory asset recovery, mobile TEEEF and rate case expense are all See Rider lines on the over-10 kW schedule. None of them is in the figures above.
- Which riders apply in this area
- The Transition Charge, Nuclear Decommissioning Charge, System Restoration Charge and ADFIT Credit are marked as applying only to customers served in the area previously served by AEP Texas Central Company.
- Up to 10 kW schedule
- Secondary Voltage Service Less Than or Equal to 10 kW is for non-residential secondary voltage with demand of 10 kW or less. Customer Charge $1.45 and Metering Charge $4.21 (not applied to unmetered service), each per Retail Customer per Month; Distribution System Charge $0.026454 per kWh. If monthly peak demand exceeds 10 kW the customer moves to the over-10 kW schedule for not less than twelve months.
This page lists Secondary Voltage Service Greater Than 10 kW (with Secondary Voltage Service Less Than or Equal to 10 kW) only. The Residential, Primary Voltage, Transmission Voltage and Lighting schedules, and the riders and their factors, are in the tariff but are not listed here. Your schedule code is printed on the bill, and it is the first thing to look up.
What to pull off an AEP Texas Central bill before any conversation
- ESI ID — the identifier that determines territory and eligibility
- Rate schedule code as printed on the bill
- 12 months of kWh, and peak kW if the account is demand-metered
- The delivery and supply sections, kept separate
- Current supplier and contract expiry, if any
