To comply with operational standards, what is the minimum alteration to a dynamic schedule flow value that triggers a Tag update?

To comply with operational standards, the minimum alteration to a dynamic schedule flow value that requires a Tag update is determined by ensuring that the transmission system operates reliably while maintaining accurate and up-to-date information about the scheduled flows. A dynamic schedule is a method used to schedule and confirm the total flow of electricity from one part of the grid to another.

In this context, the industry standard specifies that any change in the scheduled flow that exceeds a certain threshold necessitates an official update to ensure all stakeholders have current and accurate data for operational decision-making. The threshold of 26 MW for triggering a Tag update ensures that minor variations that do not significantly impact stability or reliability do not require updates, thereby reducing administrative burden while maintaining the integrity of the system.

This requirement helps ensure that the operational practices align with the reliability standards set forth by NERC, which promotes the reliable operation of the electric grid. It's crucial for balancing the supply and demand of electricity and coordinating activities across different utilities, thus supporting the overall stability of the North American electric transmission network.
