RC West

The California ISO is the Reliability Coordinator of record for its footprint, and has extended these services to other balancing authorities in the western United States. After more than a year of planning and stakeholder input, the new service, RC West, launched operations on July 1, 2019.


What is a reliability coordinator?

A Reliability Coordinator has the highest level of authority and responsibility for the reliable operation of the power grid, and has a wide-area view of the bulk electricity system. It is required to comply with federal and regional grid standards, and can authorize measures to prevent or mitigate system emergencies in day-ahead or real-time operations. The RC also provides leadership in system restorations following major events.
