What is the required notice for a transmission outage due to an equipment problem or trip?

The requirement for notice regarding a transmission outage caused by an equipment problem or trip is that no notice is needed. This is designed to facilitate a prompt response to unplanned situations, allowing operators to address equipment failures or trips quickly without being constrained by notification timelines. In such cases, the priority is to restore service and ensure reliability, as delays could lead to exacerbated issues or greater disruptions within the transmission system.

In contrast, other situations typically warrant advance notifications to ensure proper management of the power network and coordination among operators, which is why options like a week’s notice, a three-day notice, or a 24-hour notice are usually applicable only for planned maintenance and unavoidable scheduled outages.
