Just had call with Oncor’s CEO and senior leadership. The power generation increase @ERCOT_ISO forecast for last night didn’t happen. During our call ERCOT demanded an additional 500 megawatts be pulled from transmission bringing the up to the minute total to 18,500 shed...

280k customers in @DallasCountyTx without power. @oncor reports they were able to cycle most customers with extended outages on for roughly 30 minutes an average of three times last night but many didn’t get that. Transformers are breaking and where that is happening....

Power won’t come on. That adds to the complexity of the problem. Transformer issues are increasing but not yet widespread. I believe the main problem is a lack of generation as plants and turbines that weren’t required to winterize continue to be offline.

Just took a call from @ERCOT_ISO CEO, John Magness. He expects a peak at 9 am. Power generators see a morning peak on weekdays as people prepare for work and open business.
Please keep your business closed today for all but what’s necessary not to spoil materials and stay home!

@ERCOT_ISO says shed may increase to 20,000 megawatts from current 18,5k this am but the goal is to decrease that shed number. That will be determined by consumption and success in getting/keeping plants online.

Due to the lack of success in getting plants online and the severity of this situation, I ask all non @CISA businesses to work virtually or close to all but essential maintenance to help conserve energy today.
