In the wee hours of the morning on Sunday, the mighty state of Texas was asleep. The honky-tonks in Austin were shuttered, the air-conditioned office towers of Houston were powered down, and the wind whistled through the dogwood trees and live oaks on the gracious lawns of Preston Hollow. Out in the desolate flats of West Texas, the same wind was turning hundreds of wind turbines, producing tons of electricity at a time when comparatively little supply was needed.
And then a very strange thing happened: The so-called spot price of electricity in Texas fell toward zero, hit zero, and then went negative for several hours. As the Lone Star State slumbered, power producers were paying the state’s electricity system to take electricity off their hands. At one point, the negative price was $8.52 per megawatt hour.
