The Electric Reliability Council of Texas (ERCOT) does it for you. When you sign up for a plan with a new provider, ERCOT will send you a mailer confirming the switch. You have three days upon receiving the mailer to change your mind. If you don't, you'll have a new provider within seven days, and ERCOT will notify your old provider. Just remember, if you abandon a contract before it's complete, you will be on the hook for any fees or penalties detailed in its Terms of Service.
For example, if you use a small amount of energy each month, you expect to be rewarded — right? Unfortunately, nearly all electricity plans from Texas REPs are advertised as costing more per kWh the less electricity you use. It’s a little like buying in bulk: Providers often discount your bill when you cross certain kWh thresholds. For instance, one 12-month plan from StarTex Power quotes 8.1 cents per kWh for 1,000 kWh a month and 8.8 cents for 2,000 kWh per month, but 12.1 cents for 500 kWh per month. Why the difference? Customers get $35 back each month if they pass 1,000 kWh of use, and another $15 back per month if they cross 2,000 kWh. In this case, using half as much electricity as your neighbor on the same plan wouldn’t get you half the bill.
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. 
Fixed-Rate Plans: These plans are steady and predictable; the price per kWh you sign up for will remain that same for the entirety of your contract. (The only changes in your bill will be from forces outside of your REP's control, like changes in TDU fees, or changes in federal, state, or local laws.) Often fixed-rate plans will have a slightly higher price per kWh than others, but you're paying for the predictability. They're great if you live by your budget – and even greater if you happen to sign up when rates are low. The fixed-rate plans of our five Texas providers typically started at 12 months, with some extending up to three years, but we spotted a couple from Reliant that offered fixed rates for six month contracts as well.
According to the EIA, the overall average price of electricity for commercial customers in the US is 10.51 cents, while Texas business customers pay on average 8.23 cents per kWh (as of May 2018) for electricity. Is your business paying more? You may be able to save significantly, especially if your business is on a month-to-month or short term contract.
When looking at the variety of retailers, you can choose from long- or short-term contracts; fixed, variable or indexed rates; and traditional or renewable energy plans. Some retail electricity providers even offer rewards programs that give you bill credits, gift cards or other perks for paying on time or referring new customers. You also have lots of options when it comes to paying your bill. Many providers accept credit card, online or over-the-phone payments. It's easy to make the power supply switch and worth the time if you can save on your electric bill. One phone call is all it takes to switch power providers in Texas. You can get the plan that works well for you when you exercise your power to switch today!
The average prices shown in these calculations represent average annual prices per kilowatt-hour (kWh). Some REPs charge rates that vary by season or usage level. As a result, the actual average price listed on a customer's bill for any given month may differ from that listed here, depending on the usage of the customer and the actual rates charged during that month. Please see the REP's Terms of Service document for the actual rates that will be charged by the REP.
The Public Utility Commission (PUC) has a website to help you find and compare all the electricity plans and providers in your area. Visit www.powertochoose.org or call 866-PWR-4-TEX (1-866-797-4839). You can filter your options based on your usage, your preferred plan type, and several other factors. Once you’ve chosen the retail electricity provider that best suits your needs, you can sign up directly from their website.
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.
