Deregulation in Texas allows most residents and business owners to choose which company they purchase a power plan from. The state’s electricity providers, also known as retail electric providers (REPs), work closely with utility companies, including TNMP. Your local utility company is assigned based on coverage areas.
However, while utilities are responsible for delivering power, REPs are tasked with selling electricity plans to consumers and managing customer billing. Your REP will issue your electricity bill, which will include your usage charge, utility delivery fees, and government fees and taxes.
A wide variety of top-rated REPs operate in TNMP’s service area. Some of the most popular providers you can find on our marketplace include:
