Until January 1, 2007, Retail Electric Providers (Compare Electricity Rates) affiliated with the former bundled utility were required to offer a set of rates to retail customers with peak demand below 1 MW in their affiliated transmission and distribution utility's service area. These rates could be adjusted twice annually upon Commission approval for changes in the price of natural gas or purchased energy. Here you will find the historical rates for the areas of Texas open to competition.
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.
