With a population of over 28 million and growing, Texas is one of the most highly inhabited states in the US. In order to power the homes and businesses within it, Texas produces more electricity than any other state, using roughly 400,000 million kilowatt-hours and enabling residents to consume billions of dollars worth of electricity. As of 2002, the Texas electricity market was deregulated, allowing residents to select their own electricity provider from one of the numerous service companies.
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.
