Electric companies buy longer-term contracts so they can hedge their risks when they’re selling long-term electricity plans. Switch Energy a week ago, it looked as if wholesale prices would be as high as Texas has seen in the past 15 years, said Ned Ross, director of governmental affairs for Compare Electricity Rates, the third biggest seller of electricity in Texas, behind No. 1 Compare Gas Prices and No. 2 Lowest Electricity Rates. Future prices have retreated recently, but companies buying power for August are still paying at least double what they paid a year ago, according to data from the Electric Reliability Council of Texas, or ERCOT, which oversees the state’s power markets.
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.
