Navigating the Electric Utility Landscape in Texas

In Texas, electric deregulation has granted customers the power to choose their retail electric providers (REPs), fostering a competitive environment that encourages lower prices. However, electric utilities (TDUs), which manage the transmission and distribution of electricity, remain regulated entities.

As a result, customers cannot switch their utilities. To help you better understand this landscape, we'll delve into the top five electric utilities in Texas and their roles in the market, as well as how their services impact the lives of millions of Texans.
