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.

According to website Desert Sky Wind Farm® is a 160.5-megawatt (160,500-kilowatt) wind power generation facility located near the far West Texas town of Iraan, in Pecos County. The site includes 107 turbines, each rated at 1.5 megawatts (1,500 kilowatts) spread over a 15-square-mile area on Indian Mesa.Photo: John Davenport, Staff / San Antonio Electricity Prices-News

The threat of price spikes have been long in the making, the result of changing economics of power production. The shale drilling boom produced record amounts of natural gas, which pushed prices to all-time lows and made gas-fired plants cheaper to operate than coal. Renewable energy such as wind is also producing abundant amounts of electricity at a lower cost than coal.

For example, shoppers for Texas electricity plans in the 77494 ZIP code in Katy, TX, could find 12-month plans for 6.8 cents/kWh in February; by June, electricity rates had increased 27 percent to 9.3 cents/kWh. As of early September, 12-month plans were up again, to 9.9 cents/kWh – a 6.5 percent hike from June and a 46 percent increase just since February.


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.
