Minimum Usage Fees: Often set at or around 1,000 kWh/month, these fees mean you’ll always pay for at least that amount — even if you only use, say, 800 kWh of electricity some months. It sounds nasty, but it’s only something to be concerned about if your electricity bills historically show you hover right around that minimum use threshold. If you’re electricity use always exceeds that amount, it’s like it’s not even there.
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 2Best Electric 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. 
Energy sellers must provide collateral to ERCOT to cover expected future costs of buying wholesale electricity and if the companies don’t have enough capital, they get shut down. Gas And Electric Companies Energy, a Dallas-based electricity retailer that sold wind-energy plans to 9,800 customers including many in the Houston area, got caught in that financial squeeze when it defaulted on its collateral obligations.
The price to beat seemed to accomplish its goal of attracting competitors to the market during the period through January 1, 2007. It allowed competitors to enter the market without allowing the incumbents to undercut them in price. It has also given energy consumers the ability to compare energy rates offered by different providers. The less-regulated providers undercut the price to beat by only a small margin given that they must balance lower prices (to attract customers and build market share) with higher prices (needed to reinvest in new power plants). Due to the small difference in competing prices and slow (yearly or so) "buying" process, price decrease due to competition was very slow, and it took a few years to offset the original increase by "traditional" electric providers and move to lower rates.
On the other hand, month-to-month variable rate (no-contract) plans don’t have cancellation fees. You won’t be penalized if you find a better deal elsewhere and want to make another switch. And, you won’t be stuck paying more than you should be if the market rate for electricity trends down. But, if it goes up, you’ll be paying more than your in-contract neighbors, and you’ll likely want to shop around again for a better deal.
The Texas Senate Bill 7, passed in 2002, gave 5.6 million Texans the power to choose a retail electric provider (Gas And Electric Bill) to supply electricity to their home or business. This bill facilitated a competitive energy marketplace that 85 percent of Texans can capitalize on today. Energy choice is available to residents in Houston, Dallas/Fort Worth as well as other cities in Texas.
