Moving to Texas?

If you’re new to the state, you may or may not have heard of “deregulation,” and depending on the location, you might be moving into an area that is deregulated. Reliant wants to simplify your moving experience by getting you acquainted with this topic. As you will see, in a deregulated electricity market, customers have choices that make electricity buying a lot more personal.

What is deregulation?

In most of Texas, the electricity industry is deregulated. In these areas, this means that there are no fully integrated utility companies that own and run the generation, wires, poles and electricity that flows to the customer. Instead, people can purchase electricity from the energy supplier of their choice.

In contrast, in states and areas of Texas where the electricity industry is regulated, electricity is delivered to homes and businesses by a single utility company, in a "one-size- fits-all" fashion, without the power of choice.

In areas of Texas and other states where the market is deregulated, the electricity industry is open to competition, which means residents can shop for plans, compare prices and choose the retail electricity provider, or REP, that best fits their needs.

Benefits of a deregulated electricity market:
  • Exceptional customer service
  • Energy management tools
  • Competitive prices
  • Variety of plans

How is electricity delivered in a deregulated market?

In deregulated areas, electricity is delivered to an REP's customers through a Transmission and Distribution Service Provider, or TDSP. The TDSP, or utility company, is determined by the area in which the customer lives. The TDSPs in Texas are: CenterPoint, AEP Texas, Texas-New Mexico Power and ONCOR. 

  • First, electricity is produced by generators, and Reliant purchases the electricity needed for its customers.
  • Electricity is then transported from power-generating stations, through towers and distribution lines, until it arrives to the customer’s physical address.
  • Finally, Reliant supplies electricity through plans that fit your lifestyle and award-winning customer service.

The difference between a Texas utility company and a Texas retail electricity provider

In Texas, there are several utility companies that energy providers such as Reliant work with. Most commonly referred to as a TDSP (Transmission and Distribution Service Provider), other names for a utility company include: TDU (Transmission and Delivery Utility) and distribution service provider. An energy provider, on the other hand, is also known as an REP (retail electricity provider).

TDSPs and REPs each have their specific role and responsibility in our Texas electricity market. Below you will find information about what each of their roles are, and when you should call them.
TDSP is responsible for:
  • The transportation and delivery of power to your home or business
  • Maintenance of electrical equipment
