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.
One of the benchmarks of a successful free market is the range of choice provided to customers. Choice can be viewed both in terms of the number of firms active in the market as well as the variety of products those firms offer to consumers. In the first decade of retail electric deregulation in Texas, the market experienced dramatic changes in both metrics. In 2002, residential customers in the Dallas-Fort area could choose between 10 retail electric providers offers a total of 11 price plans. By the end of 2012, there were 45 retail electric providers offering 258 different price plans to residential customers in that market. Similar increases in the number of retail electric providers and available plans have been realized in other deregulated electricity market areas with the state.
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.
