Despite the fact that Texas sees much higher temperatures year round, most households contain and use heating units. These units generate heat in one of four ways: other, propane, electricity and natural gas. Just over half of households in Texas use electricity to run their heating units. This is a much greater average than the overall average for the nation.
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. 
Last week, The Dallas Morning News’ The Watchdog published an article exposing deceptive practices by Texas energy brokers and retail electric providers. The article talks of how these companies have attempted to lure buyers with deceptive 1-cent per kWh offers and websites that appear to be knockoffs of the public utility commission’s Power to Choose.
Due to the increased usage of natural gas immediately after deregulation, new-era energy tools such as wind power and smart-grid technology were greatly aided. Texas' first "renewable portfolio standard" — or requirement that the state's utilities get a certain amount of their power from renewable energy like wind — was signed into law in 1999, as part of the same legislation that deregulated the electric market.
Fixed-rate plans: Fixed-rate plans give customers more stability for their monthly energy bills because the rate a customer signs up with is the rate he or she pays for the length of the plan’s contract. Most fluctuation comes with usage, though transmission and delivery charges and local fees also can change.. Because a fixed-rate plan sometimes spans two-three years, these plans often require a customer credit check and can include early cancellation fees. Fixed-rate plans, because of the continuing market volatility, probably are the best choice for many consumers.
The ability to make an electric power switch gives Texas energy consumers the freedom to shop and search for a new rate. Texans switch power providers for a number of reasons. You may choose to switch power supply providers because you move to a new utility area that your current retail provider doesn't service. Maybe you switch power providers because you're unhappy with your current provider's level of customer service. Maybe your reason for switching is simply to find a better rate than what you have now. Whatever your reason may be, you have the power to switch electricity providers.

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.
Which ones the best? Like all things energy, it depends. Do you prefer predictability, or do you like the idea of potentially saving some cash by monitoring the market? Our (albeit conservative) recommendation: Fixed rate is probably best. Energy prices are on the rise — the U.S. Energy Information Administration predicts a 3 percent increase in residential electricity prices in 2018.

Since the Texas electricity market opened to competition in 2002, many Texas residents have had the opportunity to choose their own electricity provider. Instead of relying on their local utility to provide them with electricity, most Texans can choose from a variety of competitive providers, allowing them to shop around for the perfect electricity plan for their homes and lifestyles.
For example, shoppers for Texas electricity plans in the 77494 ZIP code in Katy, TX, could find 12-month plans for 6.8 cents/kWh in February; by June, electricity rates had increased 27 percent to 9.3 cents/kWh. As of early September, 12-month plans were up again, to 9.9 cents/kWh – a 6.5 percent hike from June and a 46 percent increase just since February.
