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.

This is one area where going green and saving money diverge. The cheapest renewable tariffs tend to cost more than the cheapest standard tariffs, so it really is a question of your personal politics. However, if you can afford to go renewable, then it's a help to the environment, and all the main comparison services allow you to compare renewable tariffs.


Your most effective weapon, however, is a site like ComparePower (Power to Choose) to locate and compare details from various Houston electricity resellers.  In one fell swoop, you will efficiently and quickly locate and classify cheap electricity resellers all on one page, instead of wasting your valuable time searching out available companies and visiting their websites one by one (who even does that any more?).
 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.
When you use our rate comparison process, providers know that they are competing to win your business. Consequently, they offer cheap electric rates in hopes of becoming your new Texas electricity company. This benefits both you and the provider you select. You receive a cheap electric rate and the plan of your choice, and the provider adds another satisfied customer.

Like we said, fees don’t necessarily make for a bad plan — although it’s worth it to do the math to see if you can save with another provider. For example, compare TXU Energy’s Simple Rate 12 plan with its $9.95 base charge, alongside Direct Energy’s Live Brighter 12 plan with a smaller base charge, and Reliant’s Digital Discount plan with no base charge. We’ll use a Corpus Christi ZIP code and assume 1,000 kWh/month of energy use.

Twenty-nine states have deregulated electricity, natural gas or both. That allows you to shop for the supply portion of your bill from alternative providers who may offer rates lower than the default supplier – usually a utility. Delivery services and billing will remain the responsibility of the local utility as they own the power lines and wires that keep the lights on.
