The growth in wind power and natural gas fueled power will offset the loss in coal over time but for the summer of 2018, expected record demand for electricity will converge with power plant closures to put a squeeze on wholesale electricity rates. This, in turn, will cause the retail electricity prices paid by most Texas consumers to increase. The rise in wholesale rates could be particularly dangerous for consumers who have electricity plans that are tied directly to the wholesale price of electricity.
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.
