How does that work? Spark Energy buys electricity and competes in the market for the best price -- a competition that ultimately drives prices down and allows us to deliver more value for your money. In Texas, switching to a different electricity provider is kind of like changing to a different long distance company. When you switch to Spark Energy, the utility will continue to deliver electricity to your home but Spark Energy will handle all the billing, including the utility’s delivery fees and the electricity you actually use.

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.
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.

Texas electricity deregulation has given millions of Houston residents and businesses the power to choose the cheapest electricity rate. According to ERCOT, over 92% of Texas homes and businesses who live in deregulated areas have switched electric companies since deregulation began in 2002. Even though electric choice in Texas has been hugely successful for energy savings, customers are still confused by the options, terminology, and overall process of switching electric providers.
 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.
