What is the minimum time frame for giving notice of a transmission outage that is 5 days or less?

The correct choice is based on established protocols within the PJM (Pennsylvania-New Jersey-Maryland) Interconnection framework regarding transmission outages. For outages that are scheduled to last 5 days or less, PJM requires a minimum of 3 days' notice. This requirement allows adequate time for affected parties, including transmission operators and customers, to make necessary adjustments to their operations and energy management plans.

Providing notification within this timeframe helps ensure system reliability and coordination among various stakeholders. It also enables better planning for maintenance and minimizes the potential for disruptions in service. By requiring at least 3 days of advance notice, PJM helps maintain operational integrity while facilitating communication and collaboration among utilities, operators, and customers impacted by the outage.
