Before disconnecting an affected facility due to overload, NERC reliability standards require what action?

The requirement to notify neighboring systems impacted by a disconnection due to overload is grounded in the principles of maintaining reliability and coordination within the interconnected electric grid. When a facility experiences an overload and needs to be disconnected, it is crucial to ensure that surrounding utilities and systems are aware of the change in operational status. This notification allows them to prepare for potential impacts on their own systems, which helps to enhance overall grid stability and reliability.

By communicating with adjacent systems, operators can better manage their generation resources, coordinate emergency responses, and mitigate any cascading effects that might arise from the disconnection. This proactive approach is an essential part of ensuring the reliable operation of the bulk power system, as it fosters collaboration among different operators and helps maintain the integrity of the electrical grid.
