Know your Texas utility company

Deregulation changes the relationship between customers and their utility companies. In regulated cities, customers are forced to buy electricity from the local utility. However, in most parts of Texas, you have the power to choose your energy plan from any retail electricity provider serving your area. Residents and businesses can explore plans and rates from dozens of electric companies in Texas with the Choose Texas Power marketplace. Enter your ZIP code to compare rates and find the best fit for your energy needs.

In this environment, Texas utility companies still play an important role. Regardless of where you buy your power, you’ll need to know your Texas utility company and have its contact information handy.

Responsibilities of Texas utility companies

Utility companies in Texas maintain the electrical infrastructure, deliver power, and fix outages. You can choose your electricity provider and shop for cheap Texas electricity rates, but you can’t select your utility — it is determined by where you live. Although you’ll find many electricity providers in your area, you’ll have one utility assigned to you.

Whether you’re establishing a new service or switching to a new electric provider, it’s important to know which Texas utility company services your area. During a power outage, you’ll need to contact your utility company to report the problem. Your electric bill will also include some transmission and delivery fees from your Texas utility company.

Most Texas cities only have one utility company, but a few areas are served by multiple 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 Texas utility company for your ZIP code.
