If a 6-day outage begins in October, when must it be submitted to be considered on time?

To determine when a 6-day outage beginning in October must be submitted to be considered on time, it is important to understand the submission deadlines related to PJM practices. In this scenario, if the outage starts in October, it must comply with PJM's scheduling and notification rules, which typically require outages to be reported within a specific period.

Given that outages scheduled in October would need to be submitted in line with the rules set forth by PJM, the correct timeline for submission reflects the planning cycle and notification requirements that PJM follows for reliability and operational efficiency. The period associated with the outage allows sufficient lead time for PJM to make necessary adjustments in the electricity transmission grid and inform relevant stakeholders.

Therefore, the answer indicating March 31st aligns with the typical submission deadline for outages that commence in October, ensuring that all operational and reliability protocols are adhered to in a timely manner. This adherence is crucial for maintaining the stability and reliability of the electricity transmission system within the PJM jurisdiction.
