How Texas electricity choice works

Texas has a unique deregulated electricity market managed by ERCOT. You choose your REP (Retail Electric Provider) while your TDU (Transmission and Distribution Utility) handles delivery.

REPs sell the electricity. They compete for your business with different rates and plans.
TDUs deliver the power. Oncor, CenterPoint, AEP Texas, and TNMP own the power lines.
PUCT regulates all REPs. The Public Utility Commission of Texas licenses and oversees all providers.
Check the EFL. Every plan has an Electricity Facts Label showing the true cost at different usage levels.

Important: Understand Texas Rates

1 Advertised rates are at 2,000 kWh. Most Texans use 1,000-1,200 kWh. A 10¢ plan at 2,000 kWh could be 13-14¢ at your actual usage.
2 Check the EFL. The Electricity Facts Label shows rates at 500, 1,000, and 2,000 kWh. Compare at YOUR usage level.
3 TDU charges are separate. Delivery charges from your TDU (Oncor, CenterPoint, etc.) add $30-60/month to your bill.
4 Watch for usage credits. Some plans give bill credits at high usage, making low-usage customers pay more.
