RC West

The California ISO's RC West is the Reliability Coordinator (RC) of record for 25 balancing authorities and 39 transmission operators in the western United States, some of whom operate as both balancing authorities and transmission operators. An RC oversees grid compliance with federal and regional grid standards, and can determine 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.
