One desired effect of the competition is lower electricity rates. In the first few years after the deregulation in 2002, the residential rate for electricity increased seven times, with the price to beat at around 15 cents per kilowatt hour (as of July 26, 2006, www.powertochoose.org) in 2006. However, while prices to customers increased 43% from 2002 to 2004, the costs of inputs rose faster, by 63%, showing that not all increases have been borne by consumers. (See Competition and entry of new firms above for discussion on the relationship between retail prices, inputs, and investment.)
Since Texas' electricity market was deregulated in the late nineties, multiple Retail Electric Providers (REP) have either launched in Texas, or providers in other states have begun to extend their reach to Texas residents (e.g., Spark Energy, 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.
