Coastal Bend is AEP Texas territory inside ERCOT South load zone. AEP Texas delivers the power and maintains the wires whoever supplies it, so competitive supply carries no reliability consequence — only a lower price.
AEP Texas delivers power along the Coastal Bend while retail supply stays fully competitive. The ERCOT South zone behaves differently from Houston or North: it hosts a large share of the state's wind interconnection, which regularly pushes zonal prices down overnight and occasionally negative, while heavy industrial process load holds a steady floor under daytime demand. That combination makes indexed and block-and-index structures unusually attractive here for facilities that can run flexible load at night — a structure we would not recommend to the same business in Dallas. AEP Texas distribution charges also differ from both Oncor and CenterPoint, so a Texas-wide portfolio cannot be priced off a single delivery assumption.
Texas opened to competition in 2002, but the terms are set territory by territory, not statewide. AEP Texas's distribution rates, its default supply price and its rate schedules are all set independently of the other utilities in Texas — which is why an offer that is genuinely competitive in one part of the state can be mediocre here. Everything on this page is scoped to AEP Texas specifically.
Which schedule you are on sets the shape of the bill before a single kilowatt-hour is priced.
| Schedule | Typically covers |
|---|---|
| Secondary Service | standard commercial accounts |
| Primary Service | facilities at distribution primary voltage |
| Transmission Service | refining and petrochemical sites at transmission voltage |
Schedule names, demand thresholds and eligibility rules change with each rate case, and the schedule an account was originally placed on is frequently no longer the one that fits it. We verify yours against the actual bill rather than assuming — that check is free, and it is where a meaningful share of the savings on this page comes from.
Refining, petrochemicals, port and export terminals, and wind generation interconnects dominate commercial load here. Each sector carries a different load shape on AEP Texas, and the strategy changes with it.
