The Reliability Coordinator shall approve or disapprove, with stated reasons, the Transmission Operator's submitted restoration plan within _____ following the receipt of the restoration plan from the Transmission Operator.

• A. 60 calendar days
• B. 10 calendar days
• C. 45 calendar days
• D. 30 calendar days

Answer: (D)

The key idea is that there is a fixed time window for the Reliability Coordinator to review and either approve or disapprove a Transmission Operator’s system restoration plan, and to provide reasons if disapproval is necessary. This timing ensures coordinated action and timely readiness across entities during recovery from an outage. Thirty calendar days is the best fit because it strikes a balance: it gives the Reliability Coordinator enough time to thoroughly assess the plan, check for completeness, verify coordination with other entities, and document clear reasons if disapproval is warranted. At the same time, it keeps the process moving so the Transmission Operator can revise and resubmit promptly and restoration planning stays on schedule. The other options would either squeeze the review too tightly (making thorough evaluation difficult) or delay restoration planning (which could hinder timely recovery).
