What is the Synchronized Reserve Requirement based on?

The Synchronized Reserve Requirement is primarily based on the need to ensure reliability in the face of potential sudden losses in power generation or transmission facilities. It specifically relates to the ability of the grid to recover from disturbances, such as a generator failure or power line outage, and is directly tied to the largest single contingency that could occur on the system. By setting the requirement at 100% of the largest single contingency, the system can react effectively and maintain stability, allowing for the necessary resources to be dispatched quickly in response to such an event.

This approach helps maintain the balance between supply and demand, ensuring that there is always enough backup support available to prevent system disturbances from escalating into larger power outages or reliability issues. The other options do not reflect the operational priorities that specifically address grid reliability and contingency management in the same way.
