Managing outages helps ensure system reliability

Accurate and complete outage scheduling is vital to reliable operation of the transmission system. The ISO coordinates outage schedules for maintenance, repair and construction within the ISO grid to maintain system reliability, maximize schedule feasibility and ensure effective planning for resource use.  

Requirements, guidelines and procedures

All forced outages must be reported to the California ISO with a description of the cause and all remedial actions taken.
