Oncor follows a systematic process to evaluate and restore power. Our restoration philosophy – to safely and quickly restore power to the greatest number of customers – along with improved technology helps us determine where to go and what to repair first.
We start our work by identifying the circuit-related issues causing the outages in our system. Damage evaluators are also deployed to identify the location and scope of damages. As repairs begin, here's how the restoration prioritization process typically works:
Transmission line power outages affect thousands of customers since these high-voltage lines deliver electricity to entire neighborhoods and businesses. Because the loss of a transmission line affects so many, this type of restoration often has the highest priority.
Critical facilities, such as hospitals, fire stations water and sewer plants, are also top priority since these facilities impact lives and first responders.
Our next priority would be outages on the distribution system that deliver power to homes and businesses affecting several hundred consumers.
Power outages at single residences or businesses would follow all of the above in priority.
Though Oncor may designate certain equipment at a higher priority level in our restoration strategy, repairs outside of that scope are happening simultaneously. Smaller areas may see power return at the same time or earlier than larger ones.
