According to NERC Standard EOP-005, with whom must communication occur at the onset of a major system event?

The correct response highlights the importance of maintaining clear and direct communication with power plants and critical substations at the onset of a major system event, per NERC Standard EOP-005. This is essential because power plants and critical substations are vital components of the grid that may be directly impacted by the event.

Establishing communication with these entities ensures that operators can assess the situation accurately, coordinate responses, and implement necessary actions to maintain system reliability and security. This includes sharing real-time information regarding system status, operating conditions, and any immediate actions required to mitigate impacts on the power supply.

Other entities, such as local government agencies or the media, play important roles in their respective capacities, but the immediate focus during a major system event must be on the operators and facilities that directly manage the flow of electrical power. This priority enables a more efficient and effective response to restore system stability and protect the electrical infrastructure.
