What AEP Texas Actually Does
AEP Texas is a Transmission and Distribution Utility (TDU). It owns and maintains the physical infrastructure: the high-voltage transmission lines, the local distribution wires, the poles, transformers, and meters that carry electricity from generation plants to homes and businesses. It does not generate electricity, and it does not sell electricity to consumers.
Under Texas deregulation, governed by the Public Utility Commission of Texas (PUCT), retail electricity providers (REPs) compete to sell power, but every REP in AEP Texas territory uses the same AEP wires to deliver it. Choosing a different retail provider does not change who shows up when the power goes out. That responsibility belongs to AEP Texas, regardless of which REP a household has chosen.
AEP Texas is a subsidiary of American Electric Power (AEP), one of the largest electric utilities in the United States. Its Texas operations serve roughly 1.1 million customers across a combined service area that covers more square miles than many U.S. states.
Is My Address in AEP Texas Territory?
The fastest way to confirm is to enter an address or zip code on the Power to Choose website (powertochoose.org), the official PUCT marketplace. The site identifies the TDU for every address in the deregulated market.
As a general geographic guide, AEP Texas territory covers:
- Corpus Christi and the Coastal Bend (AEP Central)
- Laredo and the surrounding area (AEP Central)
- Victoria, Cuero, and surrounding counties (AEP Central)
- Abilene, San Angelo, and the surrounding region (AEP North)
- Wichita Falls and North Texas outside of Oncor territory (AEP North)
- Del Rio and the Trans-Pecos area (AEP North)
Areas not served by AEP Texas include Houston (CenterPoint Energy), Dallas-Fort Worth (Oncor), and most of the Panhandle (Xcel Energy). Those regions have their own TDUs with separate rate structures.
AEP Central vs. AEP North: What Is the Difference?
AEP Texas operates under two distinct rate zones, each with its own PUCT-approved delivery tariff. The two zones are AEP Texas Central and AEP Texas North. The distinction matters for bill comparisons because delivery charges differ between them.
AEP Texas Central covers the southern portion of the AEP service area, centered on Corpus Christi. It includes the Coastal Bend, the lower Rio Grande Valley transmission zone, and parts of South Central Texas.
AEP Texas North covers the northern and western portion of the service area, including the Abilene area, Wichita Falls, San Angelo, and the far West Texas communities tied to the ERCOT grid.
The practical difference for a consumer is in the TDU delivery charge line item on their monthly bill. As of the most recent PUCT filings, AEP Texas Central and AEP Texas North carry slightly different per-kWh distribution charges and fixed customer charges. When comparing electricity plans on Power to Choose, the site automatically applies the correct TDU zone based on the address entered, so the "price at 500 kWh," "price at 1,000 kWh," and "price at 2,000 kWh" figures shown already include the correct zone's delivery charges.
A household moving from Corpus Christi (AEP Central) to Abilene (AEP North) should re-shop plans entirely, because the underlying delivery cost structure is different and a plan that was competitive in one zone may not be competitive in the other.
How AEP Texas Delivery Charges Appear on Your Bill
Every AEP Texas customer sees TDU delivery charges on their monthly bill, regardless of which retail provider they use. These charges are set by the PUCT, not by the REP, and they are identical for every customer in the same rate class within a given zone.
A typical AEP Texas residential delivery charge consists of two components:
- A fixed monthly customer charge. This is a flat fee billed every month regardless of how much electricity the household uses. It covers the cost of maintaining the meter and the connection to the grid.
- A variable distribution charge per kWh. This scales with consumption. The more electricity a household uses, the higher this portion of the delivery charge.
There may also be a transmission charge component, a distribution cost recovery factor, and other smaller riders that reflect approved infrastructure investments. The PUCT publishes the full AEP Texas tariff schedules on its website (puc.texas.gov).
Because delivery charges are fixed by regulation, a retail provider cannot lower them. A lower advertised rate from a REP reduces the energy charge component of the bill, not the delivery charge. Consumers comparing offers should look at the Electricity Facts Label (EFL) for each plan, which breaks out the energy charge from the TDU pass-through charges.
AEP Texas Outages: Who to Call
One of the most common points of confusion in a deregulated market is understanding whom to contact during a power outage. The answer is straightforward: contact AEP Texas directly, not the retail electricity provider.
AEP Texas operates a 24-hour outage reporting line. Customers can also report outages through the AEP Texas website or mobile app. The retail provider has no role in restoring power. Calling a REP during an outage adds delay without any benefit.
This separation of responsibility is by design. The PUCT structured deregulation so that the physical infrastructure remains under a regulated utility with clear service obligations, while the commodity (the electricity itself) is sold competitively. AEP Texas is required by its PUCT certificate to restore power within defined timeframes and to maintain reliability standards, regardless of which REP serves a given customer.
During major weather events, ERCOT coordinates the overall grid, while AEP Texas manages restoration within its distribution territory. Customers looking for outage maps and estimated restoration times should use the AEP Texas outage center, not ERCOT's website. ERCOT monitors the bulk transmission grid; AEP Texas handles the last-mile distribution that connects homes to that grid.
When to Shop for a New Plan in AEP Texas Territory
Switching retail providers makes sense under specific conditions. It does not make sense simply because a promotional offer arrives in the mail.
Good times to compare plans include:
- When a fixed-rate contract is expiring. Without action, most plans roll to a month-to-month variable rate that is typically higher than available fixed-rate offers.
- When the current plan's rate is above the AEP Texas market average. The EIA (U.S. Energy Information Administration) publishes average retail electricity prices by state. Texas residential customers paid an average of roughly 14 to 15 cents per kWh in 2023 (EIA, Electric Power Monthly). Plans pricing well above that range warrant a comparison.
- When usage patterns have changed significantly. A household that added an electric vehicle or replaced gas appliances with electric alternatives will use considerably more electricity, making a plan with a low fixed monthly charge and a higher per-kWh rate less favorable than before.
Switching providers in AEP Texas territory does not interrupt service and does not require a technician visit. The transition is handled electronically between the REP and AEP Texas.
The Bottom Line for AEP Texas Customers
AEP Texas delivers electricity to roughly 1.1 million customers across two rate zones in West, Central, and South Texas. It maintains the infrastructure, responds to outages, and passes regulated delivery charges through to every customer on the same terms. The retail provider a household chooses affects only the energy charge component of the bill. Shopping smart in AEP Texas territory means understanding that delivery charges are fixed, identifying the correct zone (Central or North) before comparing plans, and reading the EFL for any plan under consideration.
