As they’re advertised, the Digital Compare Electricity Companies plan appears to save you $4 — but only if you use 32 percent of your energy on the weekends, which is the stat Cheapest Electric Company used to create the average price it advertises. Say you often travel for business during the week, and are only home cranking the air conditioner on weekends. If your energy use skews to 55 percent weekend use (for Compare Electricity Companies that means 8 pm on Friday through 12 am Monday), suddenly Cheap Energy becomes a much better deal.
Since Texas' electricity market was deregulated in the late nineties, multiple Retail Electric Providers (Gas And Electric Bill) have either launched in Texas, or providers in other states have begun to extend their reach to Texas residents (e.g., Best Energy Company, which was founded in Texas). These electricity providers are providing less expensive and/or greener electricity alternatives to traditional sources of energy, in contrast with the supply consumers previously received by default through their local utility. Customers now have the option to receive their electric supply from providers other than their utility, known as alternative retail electric providers.
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. 
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.
