Controlled outages can affect customers differently based on the load reduction required by ERCOT. For example, customers near critical facilities, or those in limited areas where rolling outages cannot take place to maintain grid stability, may not experience outages, while those farther from these facilities or areas may experience multiple outages for longer periods of time. 
 
Additionally, in case there are instances of substantial generation drop, safeguards are built into our system that drop customer loads automatically to prevent cascading widespread outages, or ultimately a blackout. These are designed to be short term drops that are reset quicker than controlled outages to prepare for the next response opportunity. As these limited areas must be energized in order to provide this grid protection, it could affect you but not your neighbor. Keeping these limited areas energized also helps stabilize the system, so when controlled outages are done, we can more easily get everything reconnected and turned back on. These are diverse geographical areas across the grid, based solely on the mathematic and engineering needs of the electric system. 
 
Lastly, while these controlled outages were intended to roll throughout the service territory, the high amount of load dropped from the grid prevented us and other utilities from performing regular rotations, leading to extended periods without power for many of our customers. We continue to strive toward providing any temporary relief that we can for those who have been without power the longest as soon as enough generation is available. 
 
Outages due to storm damage also affect different customers in different ways. A downed power line might affect your home but again, not your neighbor.
