How Home Energy in Texas Works

Posted on by Everything Energy 4 minutes, 53 seconds

Many U.S. states have deregulated energy markets. But energy in Texas is distinctive because it is the only state primarily driven by its own independent electricity grid — known as the Texas Interconnection. Thanks to this unique system, Texans now have an abundance of energy options to choose from.

Let’s take a closer look at how home energy in Texas works.

Energy in Texas — Deregulation Explained

Energy deregulation — also referred to as “energy choice” — gives consumers the opportunity to choose what electricity company provides power to their home. In Texas’s deregulated electricity market, the system is divided into three main sectors: generation, transmission and distribution and retail.


This sector produces the electricity. Generation companies can be investor-owned utilities, independent power producers or renewable energy creators. The Electric Reliability Council of Texas (ERCOT) oversees this part of the system.

What does ERCOT do?
ERCOT is a nonprofit organization that ensures reliable electricity service to 90% of the state — more than 26 million people. The organization coordinates the flow of power on the electric grid and performs financial settlement for the competitive wholesale bulk-power market.

Transmission and distribution

This sector owns and operates the equipment and facilities, including the poles and wires, that deliver electricity to homes and businesses. These companies are overseen by the Public Utility Commission of Texas (PUCT).

What does the PUCT do?
The PUCT regulates Texas’s electricity (as well as its telecommunication, water and sewer utilities); implements related legislation; and helps resolve consumer complaints against these utilities.

What are the TDSPs in Texas?
There are five TDSPs that serve Texas: Oncor, CenterPoint Energy, Texas-New Mexico Power, AEP North and AEP Central.


This sector is where consumer choice comes in. Retail Electric Providers (REPs) compete with each other to sell electricity to consumers. Some REPs buy energy on the wholesale market, while others operate their own facilities and see the power they generate. REPs offer a variety of contract terms, pricing plans, energy sources and additional services to appeal to customers. Customers can then compare plans and choose the one they want. The PUCT also oversees the retail side of Texas’s electricity market.

How many REPs are there in Texas?
According to the PUCT, the state has more than 130 REPs currently doing business in Texas.

In summary, here are some important things to know about Texas’s deregulated electricity market:

What is the Difference Between Regulated and Deregulated Energy?

Where is Energy in Texas not Deregulated?

Electricity is deregulated for about 90% of Texas residents. Most major cities have deregulated energy markets, including Dallas, Houston, Fort Worth, Corpus Christi, Galveston, Waco and San Antonio. Some parts of the state, such as El Paso and Amarillo, do not have as many choices when it comes to their home electricity. These areas have municipally-owned electric utilities (“munis”) or electric cooperatives (“co-ops”) that provide electricity to residents. Munis and co-ops can decide to participate in energy choice if a resolution is passed by their boards of directors or governing body. More information about these groups can be found here.

Tips for Choosing the Right Energy in Texas’s Deregulated Energy Market

Living in a deregulated energy market lets you choose an energy provider whose plans and offerings best meet your needs. Some tips to help you pick the right energy plan for your home in a deregulated market include:

Outages and Blackouts in Deregulated Energy Markets

No matter what energy market you live in, your electricity is all part of the same grid system. For this reason, no matter which REP you choose — or whether or not you have that choice —you may experience outages or blackouts due to winter storms, extreme weather events or power grid disruptions.

You should always know who to call in the event of a power outage. Remember, TDSPs are the ones who maintain the poles and wires. So in a deregulated energy market, you don’t call the REP you’ve chosen; you call your TDSP.
