Just had this forwarded to me from Oncor Electric Delivery Area Manager Cindy Tayem:
Morning peak demand is projected to be more than 56,800 MW. Although immediate concerns for the possibility of rotating outages this morning are reduced, ERCOT will be monitoring the grid closely because additional unexpected major losses of generation could force operators to begin emergency procedures to avoid an uncontrolled statewide blackout.
The grid continues to have about 3,000 MW of generation out of service due to the effects of the extreme cold.
Rotating outages are controlled, temporary interruptions of electrical service initiated by each utility when ERCOT’s reserve power supplies are exhausted. Utilities/ transmission providers determine the location/scheduling of the rotating outages.
Rotating outages are the last step in a progressive series of emergency procedures that ERCOT follows according to market rules. We only call for controlled rotating outages as a final fail-safe measure to avoid an uncontrolled blackout across the state.
Additional updates will be distributed to the News Bulletins list and posted on the ERCOT website when we have new information.
