TDU Delivery Charge: TDU stands for transmission and delivery utility — in other words, the utility company in your area that is actually piping the energy from the power generation companies into your home. (Remember, REPs in Texas are just the middleman.) The TDU delivery charge is set by the utility and is consistent from plan to plan and provider to provider within its service areas. For example, AEP , the TDU for Corpus Christi, charges the same delivery fee for all TXU, Direct Energy, and Reliant plans. You don't typically get a choice in utility company, and therefore, these fees are pretty much unavoidable, non-negotiable, and won't factor into choosing an electricity plan or provider.
Some good news: According to J.D. Power’s 2016 survey on retail electric providers (its most current survey of the space), Texas has the highest overall satisfaction with retail electric providers out of any state. And because rates, plans, and offers can be so similar from provider to provider, customer satisfaction scores are a great way to break a tie. Think of it like choosing who to hire when you have two candidates with similar resumes — you’re going to pick the person with the glowing references.
Dallas area residents now have the option for choosing their electric provider. However, with all of the different plans that are available, it can be difficult to make the right decision for your particular electricity needs. You may find yourself overwhelmed by the number of options presented to you by all the electric company advertisements or concerned about shady marketing gimmicks.
