Compared to the rest of the nation, data from the U.S. Energy Information Administration which publishes annual state electric prices  shows that Texas' electric prices did rise above the national average immediately after deregulation from 2003 to 2009, but, from 2010 to 2015 have moved significantly below the national average price per kWh, with a total cost of $0.0863 per kWh in Texas in 2015 vs. $0.1042 nationally, or 17 percent lower in Texas. Between 2002-2014 the total cost to Texas consumers is estimated to be $24B, an average of $5,100 per household, more than comparable markets under state regulation.

The power to switch is all about knowing your rights as an electric customer. In Texas, the electricity market is deregulated. Instead of only being able to get electricity from the utility and then paying the rates the utility requires, Texas retail electricity providers buy energy from generators at wholesale prices. Providers then compete with each other to offer consumers more options in terms of their electricity plans. Every electricity consumer in Texas' deregulated markets has to choose a retail electricity provider, but once you choose you don't have to stay with that provider forever. You have the power to switch electricity providers to find the best service and the best rates to meet your electric needs.
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.
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.
