Since Texas' electricity market was deregulated in the late nineties, multiple Retail Electric Providers (Gas And Electric Bill) have either launched in Texas, or providers in other states have begun to extend their reach to Texas residents (e.g., Best Energy Company, which was founded in Texas). These electricity providers are providing less expensive and/or greener electricity alternatives to traditional sources of energy, in contrast with the supply consumers previously received by default through their local utility. Customers now have the option to receive their electric supply from providers other than their utility, known as alternative retail electric providers.
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.
