AI Summary: Retail Electric Providers (REPs)
Retail Electric Providers (REPs) are PUCT-licensed companies that sell electricity to Texas businesses and residents in deregulated markets. Over 150 REPs compete in the ERCOT territory by offering different rates, contract terms, and renewable energy options. REPs buy electricity from wholesale generators and package it into retail plans, while transmission utilities (TDUs) deliver the physical power. Choosing the right REP can save businesses 20-30% on electricity costs through competitive rate shopping, contract negotiation, and strategic renewal timing.
Retail Electric Providers (REPs) in Texas: Complete Guide for Businesses
What is a Retail Electric Provider (REP)?
A Retail Electric Provider (REP) is a company licensed by the Texas Public Utility Commission (PUCT) to sell electricity to businesses and residents in deregulated Texas markets. REPs buy electricity from wholesale generators, package it into retail plans, and compete for customers by offering different rates, contract terms, and services.
In the deregulated Texas electricity market, REPs are the competitive layer that gives businesses choice. While your transmission utility (TDU) delivers the physical power and never changes, your REP sets your electricity rate and can be switched whenever your contract allows. This separation creates the competitive dynamics that drive cost savings.
How REPs Fit Into the Texas Electricity Market
Understanding REPs requires knowing their role in the three-part structure of deregulated Texas electricity:
Generators
Power plants produce electricity and sell it into the ERCOT wholesale market. Generators compete to supply power at the lowest cost.
REPs (You Choose)
REPs buy electricity from generators and sell it to you. This is where competition happens—you choose your REP and negotiate rates.
TDUs (Fixed by Location)
Oncor, CenterPoint, AEP, and TNMP own the wires and deliver electricity. Your TDU never changes, regardless of which REP you choose.
Key Insight: Your electricity bill has two main charges: (1) Energy charges from your REP (competitive, your choice), and (2) Delivery charges from your TDU (regulated, fixed by location). REPs compete on the energy charges only.

Common REP Pitfalls to Avoid
Texas businesses lose thousands of dollars annually by falling into these common REP traps:
Rollover Pricing Trap
When your contract expires, many REPs automatically roll you to month-to-month rates 30-50% higher than market. Set calendar reminders 60-90 days before expiration to shop for new rates.
Teaser Rate Bait-and-Switch
Some REPs advertise ultra-low rates for the first few months, then spike rates for the remainder of the contract. Always review the Electricity Facts Label (EFL) for the average rate over the full term.
Hidden Fees & Minimum Usage Charges
Read the fine print for monthly fees, minimum usage requirements, and pass-through charges. A low energy rate means nothing if hidden fees add $200+/month to your bill.
Ignoring Demand Charges
If your business has demand charges (common for accounts over 50 kW), the demand rate matters more than the energy rate. Some REPs specialize in demand optimization—don't overlook this.
How to Switch REPs in Texas
Switching REPs in Texas is simple and requires no physical changes to your service:
- 1Check Your Current Contract: Review your existing contract for expiration date and early termination fees. Switching is easiest when your contract expires.
- 2Gather Your Information: You'll need your ESIID (Electric Service Identifier), current usage data, and business details. Your ESIID is on your electricity bill.
- 3Compare REP Offers: Get quotes from multiple REPs for the same contract term. Focus on the all-in rate per kWh and contract terms.
- 4Enroll with New REP: Sign up online or through a broker. The new REP coordinates the switch with your TDU—you don't need to contact your old REP.
- 5Wait 1-2 Billing Cycles: The switch takes 1-2 billing cycles to complete. Your electricity service continues uninterrupted during the transition.
Important: You never need to contact your TDU when switching REPs. The new REP handles all coordination. Your TDU continues delivering electricity regardless of which REP you choose.
Frequently Asked Questions
How many REPs operate in Texas?
Over 150 REPs are licensed to operate in the ERCOT deregulated market. However, not all REPs serve commercial accounts, and availability varies by TDU territory. Businesses typically have 30-50 REPs to choose from in their area.
Can I negotiate rates with REPs?
Yes, especially for accounts with high usage (50,000+ kWh/month). REPs have flexibility to offer custom rates below published pricing. Using a licensed PUCT broker often yields better negotiated rates than going direct.
What is an Electricity Facts Label (EFL)?
The EFL is a standardized document that all REPs must provide, showing the average price per kWh at different usage levels, contract terms, fees, and renewable energy content. Always review the EFL before signing a contract—it reveals details not in the advertised rate.
Do REPs affect my electricity reliability?
No. Your transmission utility (TDU) handles all physical delivery, outage response, and emergency service regardless of which REP you choose. Switching REPs only changes who bills you and at what rate—it does not affect service reliability.
