Texas has electricity consumption of $24 billion a year, the highest among the U.S. states. Its annual consumption is comparable to that of Great Britain and Spain, and if the state were an independent nation, its electricity market would be the 11th largest in the world. Texas produces the most wind electricity in the U.S., but also has the highest Carbon Dioxide Emissions of any state. As of 2012, Texas residential electricity rates ranked 31st in the United States and average monthly residential electric bills in Texas were the 5th highest in the nation.
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.
