The Responsible Entity shall report events per their Operating Plan within _____ of recognition of meeting an event type threshold.

• A. 12 hours
• B. 24 hours
• C. 36 hours
• D. 48 hours

Answer: (B)

Reporting events after recognizing that an event type threshold has been met is about getting timely information into the system so operators and planners can see what happened and start the appropriate analyses and actions. The window defined in the standard is set to the same-day, or within the same day, after the threshold is recognized. This timing supports prompt visibility and consistency with other time-based reporting requirements, so data is fresh and useful for reliability assessments and coordinated responses.

Choosing a very short window could make it hard to collect complete, accurate information on the spot, while a longer window would delay awareness and analysis, reducing the usefulness of the data for real-time decision-making and post-event review. The same-day frame strikes the right balance, enabling prompt reporting without sacrificing data quality.
