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¢ for your home.
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.

Comparing Texas providers

Who are the largest electricity providers in Texas?

The largest Texas Retail Electric Providers (REPs) by residential customer count are TXU Energy, Reliant, Gexa Energy, Direct Energy, Constellation, Champion Energy, Cirro Energy, and Green Mountain Energy. TXU and Reliant are both owned by Vistra and NRG respectively — the two parent companies that dominate the ERCOT residential market. Gexa is owned by NextEra. Independents like Rhythm, 4Change, and Discount Power compete on price and contract flexibility. Every REP on this page holds an active license from the Public Utility Commission of Texas (PUCT) and sells power across the ERCOT grid. Size doesn't track rate — the smallest REPs often post the lowest rates at common usage tiers.

How do I compare Texas electricity providers fairly?

Compare providers at your actual monthly kWh, not the advertised 1,000 or 2,000 kWh benchmark. The Electricity Facts Label (EFL) every PUCT-licensed REP must publish shows the price per kWh at 500, 1,000, and 2,000 kWh — those three points often disagree by three to four cents because of usage credits and tiered minimums. Pull twelve months of your own bills, average the usage, and read the EFL at that level. Then add the TDU delivery charge for your service area (Oncor, CenterPoint, AEP Texas, TNMP, or LP&L) — that's the all-in cost. A "9.8¢" headline can become 14¢ once you include delivery and the fixed monthly base charge.

What's the difference between a PUCT-licensed REP and a utility?

A Retail Electric Provider (REP) sells you the electricity and sends the bill. A Transmission and Distribution Utility (TDU) owns the poles and wires and physically delivers the power. In ERCOT-served Texas, you choose your REP — that's the deregulated half of the market — but your TDU is fixed by your address. Oncor covers most of north and west Texas, CenterPoint covers Houston, AEP Texas covers central and south Texas, TNMP covers pockets, and LP&L covers Lubbock. The Public Utility Commission of Texas (PUCT) licenses every REP and sets the TDU delivery rates. TDU delivery charges are identical across every REP for the same address — about forty percent of a typical bill — so REP shopping only moves the energy half of your cost.
