How AEP Texas and Retail Suppliers Work Together
AEP Texas serves South Texas and parts of West Texas.
AEP Texas is a TDU — no generation ownership. REP supply is required for all commercial accounts. The supply portion of your bill — typically the largest single line item for commercial accounts — is where retail competition applies. That's the piece a broker targets.
AEP Texas TDU rates are PUC-regulated. Supply portion is competitive.

Competitive REP market applies across AEP Texas territory.
The process: you authorize a supplier to serve your account, they notify AEP Texas, and the change takes effect at your next billing cycle. No technician visit. No service interruption. Same reliability, different supply rate.

Understanding Your AEP Texas Commercial Bill
A typical commercial AEP Texas bill has several distinct charges:
- Supply charge: Cost of electricity generation. This is negotiable — it's what retail suppliers compete on.
- Distribution/delivery charge: AEP Texas's fee for owning and maintaining the wires. Regulated, fixed.
- Transmission charge: High-voltage grid cost, managed by ERCOT. Regulated, fixed.
- Demand charge: Based on your peak 15-minute interval each month. Can represent 30–50% of your total bill.
- Capacity charges: ERCOT capacity market costs. Pass-through, not negotiable with suppliers.
A broker focuses on the supply charge — the one component where you have leverage. We make sure you understand all other charges so there are no surprises.

What's the difference between AEP Texas and a retail energy supplier?
