The low teaser rates for consumers available just a month ago have disappeared, making it impossible for buyers who average about 1,000 kilowatts a month to lock in a three-month rate for less than 18 cents a kilowatt-hour, according to the website, the price comparison tool run by the Cheapest Electricity Rates of Texas. A year ago, Texans shopping for a three-month contract could find rates that were less than 7 cents a kilowatt hour while earlier this spring, bargains were still available for less than a nickel a kilowatt hour.
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.
