Transmission and Distribution Utility (TDU) delivery rate changes in Texas impact your monthly electric bill. It happens every September and every March. You open up your electricity bill and notice new line items, or a different charge compared to the prior month. Most of the time, it’s small changes in the delivery rates, but these can add up. There’s no way to avoid these changes, but it helps if you understand what’s going on.
When it’s time to choose an electricity plan, it can be really confusing picking your way between all the options available and the host of initials and terms.
One of the most common sticking points for electricity customers is what, exactly, the difference is between an electricity provider (also called REP, CRES, or electric supplier) and an electric utility (also called a TDSP, TDU, or EDU). They’re both vital to the success of electricity deregulation, but they play very different roles. Understanding how they fit together can make a big difference in your overall confidence as an electricity customer trying to shop for the best electricity plan.
