How soon before the start of a schedule does the ramp for interchange schedules begin?

The ramp for interchange schedules typically begins 5 minutes before the scheduled start time. This is crucial for ensuring that the system can adjust to the changes in power flow associated with the new interchange schedule while maintaining operational reliability. The 5-minute ramp-up period allows operators to manage the generation and load levels effectively, ensuring that any changes in power exchange between entities are implemented smoothly and without disruptions to the grid.

This period is essential for coordinating the physical delivery of power. It provides a buffer for balancing generation and load, helping to prevent any sudden inconsistencies that could lead to reliability concerns. Thus, understanding the timing of the ramp-up process is a key aspect of effective grid management and resource allocation.
