What is a key role of the Reliability Coordinator in maintaining system reliability during a constraint?

The key role of the Reliability Coordinator during a constraint is to issue directives for load shedding and re-dispatching resources. This action is vital for ensuring that the system remains balanced, especially when there are constraints or potential reliability issues. When a constraint is identified, the Reliability Coordinator must take proactive measures to either reduce demand (load shedding) or adjust the generation resources (re-dispatching) to alleviate the constraints and maintain the stability of the power grid.

Effectively managing these directives is critical to preventing system disturbances and ensuring that the electricity supply meets demand without compromising reliability. By coordinating these actions, the Reliability Coordinator plays a pivotal role in protecting the integrity of the bulk power system and ensuring continued safe and reliable operation.
