Over the winter at least 151 Texans died as 4.5 million homes and businesses went without power in a massive failure created by poor planning, lack of regulation, and sheer greed.
Last week Texas Republican Governor Greg Abbott promised he had fixed the problem.
On Monday, less than seven days later, ERCOT, the Electric Reliability Council of Texas, urged customers to turn air conditioning to no cooler than 78 degrees and to conserve power, as it expects more blackouts throughout the week – this time during extreme heat.
In a statement ERCOT also asked Texans to not use ovens, washing machines, or dryers.
"If you don't need something – we are asking you to turn it off and unplug it if possible."
Many Texans, and many Americans, are furious.
