How does that work? Spark Energy buys electricity and competes in the market for the best price -- a competition that ultimately drives prices down and allows us to deliver more value for your money. In Texas, switching to a different electricity provider is kind of like changing to a different long distance company. When you switch to Spark Energy, the utility will continue to deliver electricity to your home but Spark Energy will handle all the billing, including the utility’s delivery fees and the electricity you actually use.
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.
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.
