What duration of outage should be avoided during Peak according to transmission operation standards?

In transmission operation standards, avoiding prolonged outages during peak periods is critical to maintaining system reliability and preventing significant disruptions to the electric grid. The correct selection emphasizes that any outage exceeding 5 days with a restoration time greater than 72 hours should be avoided.

The rationale is rooted in the demand placed on the transmission system during peak usage. Extended outages can exacerbate the risk of overloads, cascading failures, and can impact a large number of consumers. Keeping outages within limits helps ensure that transmission operators can effectively manage and distribute electricity, particularly when demand is highest.

Understanding the critical importance of restoring service quickly during peak times helps convey the urgency of adhering to these standards. This principle governs operational practices and decision-making about maintenance and upgrades to ensure system resilience and customer reliability.
