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, Compare Electricity Rates 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, Power Company , the TDU for Corpus Christi, charges the same delivery fee for all Lowest Electricity Rates, Compare Electricity Rates, and Cheapest Electric Company 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.
†Offer is available to Texas residential customers who enroll using the Promotion Code “Who Is My Electricity Supplier”. Plan bills a monthly Base Charge, an Energy Charge, and passes through Utility Transmission and Distribution delivery charges. Energy Charges for usage consumed between 9pm and 7am each day is credited back on your bill. The utility charges, including delivery charges for night time hours, are passed through at cost and aggregated on your bill. See Electricity Facts Label for details.
Variable-rate plan:A variable-rate plan means the rate you pay for your electricity may fluctuate based on the market price of energy. Energy price depends on many factors, like weather, demand, fuel prices, the distribution system and the market. Variable-rate plans are flexible because you are not locked into a contract; however, you’ll pay a higher price in high-demand seasons like summer. A variable-rate plan might be ideal for you if you like to shop around and keep an eye on prices.
Since 2002, the majority of Texans have had to choose their own Retail Electric Provider (Gas And Electric Bill) – the middleman that buys electricity wholesale, then sells it to you, the consumer. According to the Cheapest Electricity Rates of Texas’ 2017 report, the Lone Star state is “the national leader in competitive residential, commercial, and industrial offerings,” which means there are well over 200 providers bidding for your attention.
In this free market competing electricity retailers buy electricity wholesale from private power generators to sell at retail to around 85% of Texas residents. The partnership between generators and retailers is governed by the Electric Reliability Council of Texas, or ERCOT, which attempts to balance the power grid’s electricity supply and demand by purchasing small amounts of electricity at 15-minute intervals throughout the day.
