The interval between annual reviews of a Reliability Coordinator's Operating Procedures, Operating Processes, or Operating Plans must not exceed how many months?

• A. 12 months
• B. 15 months
• C. 18 months
• D. 24 months

Answer: (B)

The concept being tested is how often a Reliability Coordinator must review and update its operating documents. The rule sets a maximum cadence for these reviews to ensure procedures stay aligned with current operations and conditions.

The interval between reviews must not exceed 15 months. This means you should plan to review and, if needed, revise the Operating Procedures, Operating Processes, or Operating Plans at least every 15 months. Keeping within this window helps ensure that changes in the grid, lessons learned from events, new operating practices, or updates to standards are reflected in the procedures, so coordination and real-time decision-making remain reliable.

If you’re wondering about the other timeframes: 18 or 24 months would go beyond the allowed maximum, so they wouldn’t meet the requirement. A 12-month interval is also compliant because it’s within the 15-month limit, but the question asks for the maximum permissible interval.
