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.
For example, if you use a small amount of energy each month, you expect to be rewarded — right? Unfortunately, nearly all electricity plans from Texas REPs are advertised as costing more per kWh the less electricity you use. It’s a little like buying in bulk: Providers often discount your bill when you cross certain kWh thresholds. For instance, one 12-month plan from StarTex Power quotes 8.1 cents per kWh for 1,000 kWh a month and 8.8 cents for 2,000 kWh per month, but 12.1 cents for 500 kWh per month. Why the difference? Customers get $35 back each month if they pass 1,000 kWh of use, and another $15 back per month if they cross 2,000 kWh. In this case, using half as much electricity as your neighbor on the same plan wouldn’t get you half the bill.
1. Contracts: Before, there were no contracts. You signed up or you didn’t. When it’s the only game in town, you have to play by their rules. Nowadays, you’ll see these ultra-fabulous rates bandied about but it’s only by carefully scrutinizing the fine print that you’ll discover those wonderful rates come with a one-year lock-down or other catches.
