Outage Coordination
Maintenance TimelineDefinition: Initiated manuallyto remove equipment fromservice to perform work on components than could be postponed briefly but is required to prevent potential forced outage and cannot be postponed until the next planned outage.
Level 1:
Applies to equipment which must be removed from service within 24 hours. (M1)
Level 2:
Identifies equipment which must be removed from service within 7 days. (M2)
Level 3:
Applies to equipment which must be removed from service within 30 days. (M3)
