Which of the following is NOT a requirement for Reliability Coordinators regarding their restoration plans?

The correct choice highlights that keeping restoration plans confidential is not a requirement for Reliability Coordinators. Instead, the focus for Reliability Coordinators is on ensuring that restoration plans are accessible and usable by all relevant stakeholders during emergency situations. The primary emphasis is on reliability and facilitating effective communication among various entities during restoration processes.

The other options represent crucial responsibilities of Reliability Coordinators. Regularly reviewing plans ensures that they remain relevant and effective in response to evolving grid conditions and operational practices. Training system operators on these plans is vital to ensure that those tasked with executing the plans are familiar with them and can act swiftly and effectively during a disruption. Maintaining records of each Transmission Operator's plan is equally important, as it allows for assessment of preparedness and coordination among different operators. The inclusion of these requirements highlights the importance of preparedness and coordination in restoring operations following a disturbance in the power system.
