There are two main types of pricing in contracts: fixed and variable. With a fixed contract, the electric rate price you sign up for cannot change for the duration of your contract. With a variable contract, the rate price is subject to increase or decrease each day or month, based on the time of year and price of electricity for the provider at that moment. Variable pricing is often higher, but may be a good choice for those that don’t want to be locked into a contract.

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.
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.
