Final switch tips. When you make your final selection, don’t call your current electricity provider to cancel. Sign up with the new company only. Try to sign up at least five to seven days before your plan expires so the overlap between the two billing cycles is negligible. Some people switch too late and pay higher prices during the transition. If you have a smart meter, the state rule is you must be switched within 48 hours. But five to seven days is safer.

Variable-rate plan:A variable-rate plan means the rate you pay for your electricity may fluctuate based on the market price of energy. Energy price depends on many factors, like weather, demand, fuel prices, the distribution system and the market. Variable-rate plans are flexible because you are not locked into a contract; however, you’ll pay a higher price in high-demand seasons like summer. A variable-rate plan might be ideal for you if you like to shop around and keep an eye on prices.
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. 
And just like with any plan, it’s worth it to do the math to see how different scenarios will affect your bill. Take, for example, a home in Sweetwater that uses about 1,000 kWh of energy per month, and is interested in the Texas Essentials 12 plan. Zero percent renewable energy is the cheapest option — but by committing to a $5 monthly charge for its 100 percent “JustGreen” option, it’s actually cheaper than the 60 percent hybrid renewable option.
The vast majority of Texas residential consumers on fixed-rate contracts pay anywhere from 6 to 13 cents per kWh for electricity. However, searches for service in most major metropolitan zip codes on PowertoChoose.org reveal a long list of offers seemingly too good to be true, with several starting at 1 cent per kWh. These offers may appear to be a great deal on the surface, but they are often accompanied by confusing minimum usage requirements, monthly fees, and conditional bill credits. Those conditions can be easily overlooked by eager consumers wanting a bargain on their utility bills.
As a result, 85% of Texas power consumers (those served by a company not owned by a municipality or a utility cooperative) can choose their electricity service from a variety of retail electric providers (REPs), including the incumbent utility. The incumbent utility in the area still owns and maintains the local power lines (and is the company to call in the event of a power outage) and is not subject to deregulation. Customers served by cooperatives or municipal utilities can choose an alternate REP only if the utility has "opted in" to deregulation; to date, only the area served by the Nueces Electric Cooperative has chosen to opt in.
Recently, several retail electricity suppliers and brokers have begun incorporating the words “power to choose” in online advertising, web URLs, and web content that is indexed by search engines. This could skew the search results for consumers entering the term “power to choose,” directing them to websites run by brokers and suppliers rather than by the PUCT.
Residents and business owners have been able to shop Texas electricity supply rates for more than a decade. When Texans gained the ability to choose their desired energy company in 2002, the electric industry divided into two parts: supply and delivery. Retail energy companies in Texas compete for business, offering a variety of term agreements and supply rates for consumers to choose from.
