Know your utility company

Texas has had a deregulated electricity market for over two decades. Since 2002, residents and businesses throughout much of the Lone Star State have had the power to choose their own electricity companies and rates. 

Instead of merely buying from the local utility, most Texans can choose from a wide range of electric companies. These companies sell electricity to residents and businesses, and they must offer competitive rates and plans to attract customers. 

That doesn’t mean utility companies are no longer relevant. In fact, they play a critical part in the Texas energy market, and it’s important to know your utility and understand its role as an energy company.

In Texas, utility companies maintain the electrical infrastructure and deliver power to customers. Like in traditional, regulated markets, you can’t choose your utility — it’s based on your location. No matter which energy company you choose, your utility will deliver your power and handle outages. That makes it critical to know which utility to call when your power goes out.

Even when signing up for a new plan or switching electricity companies, it’s important to know your utility. Although most cities only have one utility company in their area, some towns are split between two different utilities. When you sign up for an energy plan with one of Choose Texas Power’s trusted energy companies, you’ll need to select the correct utility for your area.
