Switching Texas Retail Electric Providers

In 2002, the Texas Senate passed a bill to create the Electric Utility Restructuring Legislative Oversight Committee, which introduced Texas to a competitive energy marketplace. This made Texas one of the 30 energy choice states in the country.

What does energy choice mean?

Retail electric providers in Texas compete for your business, which can result in reduced energy costs, better customer service, more innovative energy solutions, and plans to fit your budget. For example, Constellation offers:

no sign-up fees,
exceptional customer service,
and a variety of fixed-rate renewable and electric plans.

Understanding Energy Providers vs. Utility

Utilities deliver electricity to your home. In Texas, this means your utility — which many customers refer to as light and power companies — owns the power lines, which send energy to you to power your home or business.

What is an energy provider?

Providers set the rate you pay for energy and source where your energy comes from giving you more control over your budget and your energy options. Energy providers can also offer fixed-rate plans (so you know what rate you pay every month) and bundles with other home services (like A/C repair) if this is available in your area.

Constellation is a retail electric provider in Texas, which means that we aren't the utility company that powers your home, but the one who sets your rate and contract term. As your energy provider, we provide you with customized plans, competitive electric rates, and exceptional customer service!
