Commercial electricity in the AEP Texas Central zone.

South Texas runs on a different economy than the big metros — agriculture, food processing, port and petrochemical activity on the coast, and cross-border trade through Laredo and the Valley. The AEP Texas Central delivery zone wraps all of it, and its geography and weather exposure make it worth understanding on its own terms rather than through a statewide average. Here's the picture.

What AEP Texas Central does — and what it doesn't

AEP Texas Central is the TDSP for the South Texas coast and Valley. It owns and runs the wires, poles, and meters across a dispersed territory, and it's responsible for outages and restoration. It does not set your rate — it charges a regulated delivery fee — and it doesn't pick your supplier. You choose a retail electricity provider (REP) on the open market, and that REP sets your energy price and bills you.

The delivery service is the same no matter which REP you choose, so shopping suppliers changes your price and contract terms, never your reliability or who keeps the lights on.

What AEP Central delivery charges mean for your bill

AEP Texas Central's delivery and capacity charges are set by the PUCT and are identical across every REP in the zone. Because the territory is geographically spread out and exposed to coastal weather, delivery and capacity costs here have historically run higher than in the dense urban zones — there's simply more line per customer to build and maintain.

As everywhere in Texas, those charges aren't negotiable and aren't what separates one supplier from another. The savings live entirely on the supply side, so a clean comparison strips the AEP Central pass-through out of every offer first.

What's specific about the AEP Texas Central territory

The South Texas load mix and supplier landscape both shape what a buyer should expect:

• Distinct industrial loads. Cold storage, agricultural pumping, food processing, and cross-border logistics dominate — load profiles that look nothing like an office-heavy metro.
• A smaller active supplier set. Fewer REPs actively chase business here than in DFW or Houston, so a competitive RFP benefits from deliberately broadening outreach rather than taking the first few quotes.
• Weather risk in the price. Hurricane and tropical-storm exposure is baked into both delivery rates and supplier margin assumptions, which is part of why a zone-specific benchmark matters.

How to compare commercial offers in the AEP Central zone

The fundamentals don't change, but the thinner supplier field makes process discipline pay off more:

• Strip delivery. Remove the AEP Central pass-through so suppliers are ranked on supply cost and margin alone.
• Cast a wider net. With fewer in-zone specialists, invite more bidders — including multi-zone-capable suppliers — so you're not comparing two quotes and calling it a market.
• Anchor to ERCOT. Reconcile each offer to the forward curve at lock time so you can tell a genuinely competitive bid from an opportunistic one.

Outages and reliability

For an outage, call AEP Texas at 866-223-8508 — that's the number for both the Central and North divisions. Only the TDSP can dispatch crews and restore power, regardless of which REP bills you. Your supplier handles your contract and your invoice; AEP Texas keeps the grid running.
