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.)
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.
