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.
Last year the duo said that sales would break the 500,000 milestone but significantly underestimated the market’s growth, so “at the start of 2017, Angus and I are going to throw prudence to the winds, run our hands through our grey sea-captain hair, and bet it breaks the million mark”, helped by higher oil prices, a flood of new, improved models on the market, ongoing falls in battery prices and improved charging infrastructure. The aforementioned need to improve air quality and the continued fallout from the Dieselgate scandal will play a part, too.
Fixed-rate, long-term (contract) plans provide stability in electricity rates. If market energy costs suddenly trend upward where you live, you can rest assured that you won’t have to pay more out of pocket. However, if you want to switch to a different, lower-cost plan before the end of the contract term, you’ll likely have to pay a cancellation or early termination fee.
