“Retail electricity providers” began offering the sale of electricity supply shortly after deregulation began. Texans are not required to switch to a retail electricity provider, and will continue to receive the supply of electricity from their default utility until they decide to switch. Utilities have no incentive to supply electricity since they are required by law to resell electric supply at no profit. The utilities can only profit from the transmission and delivery of the electricity – which is not affected by which company sells the supply of electricity. Since the utilities often charge higher rates than electricity providers, there is little reason to stay with the utility for electric supply.
Since 2002, approximately 85% of commercial and industrial consumers have switched power providers at least once. Approximately 40% of residential consumers in deregulated areas have switched from the former incumbent provider to a competitive REP. REPs providing service in the state include: AmeriPower, TriEagle Energy, Acacia Energy, Ambit Energy,Breeze Energy, Clearview Energy, Green Mountain Energy, Conservice Energy, Iluminar Energy, Now Power, Snap Energy, Entrust Energy, Bounce Energy, Champion Energy, Shnye Energy, Cirro Energy, Direct Energy, Dynowatt, First Texas Energy Corporation, Frontier Utilities, Gexa Energy, Glacial Energy, Just Energy, Kinetic Energy, Mega Energy, APG&E, Adjacent Energy, Spark Energy, StarTex Power, Stream Energy, Tech Electricity, Texas Power, TXU Energy, XOOM Energy and 4Change Energy.
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.
