What is the normal ramp duration for an interchange Schedule between the Eastern and TRE Interconnections?

The normal ramp duration for an interchange schedule between the Eastern and Texas Reliability Entity (TRE) Interconnections is indeed 10 minutes. This duration is defined in order to provide a specific time frame within which scheduled power exchanges can adjust to changes in demand or supply.

A 10-minute ramp duration allows for adequate time to manage fluctuations in electricity flow, enabling system operators to efficiently balance supply and demand while maintaining reliability. This time frame is essential, especially in systems as complex and interconnected as those found within the Eastern Interconnection and TRE, where timely adjustments are vital for avoiding overloads or outages.

In the context of power interchange, a ramp duration of this length strikes a balance between responsiveness to real-time grid conditions and the operational stability necessary to ensure that power systems can remain synchronized. The choice of 10 minutes reflects both industry standards and practical considerations of grid operation, thereby becoming a benchmark for ramping practices in these interconnections.
