Mid-Afternoon Update:
ROTATING OUTAGES DISCONTINUED BUT CONSERVATION STILL NEEDED
ERCOT has issued a notice that rotating outages are no longer needed at this time; however, there is a strong possibility that they will be required again this evening or tomorrow, depending on how quickly the disabled generation units can be returned to service.
Please note that some consumers are still out of power due to the winter storm conditions.
Energy conservation is still critical during peak demand hours this evening between 6 and 10 pm.
We will continue providing these updates when new information is available.
Noon Update:
CONSERVATION IS STILL CRITICAL AT THIS TIME
ERCOT is urging all consumers who can reduce their energy consumption to do so at this time. Severe weather has led to the loss of more than 50 generation units – more than 7,000 MW, and additional units are continuing to trip offline due to the extreme cold temperatures. ERCOT Grid Operations has asked the utilities/transmission providers to implement rotating outages until the load is reduced through conservation and restoration of generation units. Conservation is very critical at this time to reduce the load on the system.
Rotating outages are controlled, temporary interruptions of electrical service initiated by each utility when supplies of reserve power are exhausted. Without this safety valve, generators would overload and begin shutting down to avoid damage, risking a domino effect of a state-wide outage.
As of noon, 2000 MW of the rotating outages had been restored, and 2000 MW is remains under rotating outages.
One megawatt is roughly enough to power 200 homes in extreme temperatures.
