How frequently must inadvertent interchange be calculated and recorded?

Inadvertent interchange must be calculated and recorded on an hourly basis to ensure accurate tracking of power flows between different control areas. This frequent calculation is essential for maintaining system reliability and balance among interconnected grids. By capturing this data every hour, system operators can promptly identify and address any discrepancies in power interchange, which is critical for operational efficiency and compliance with reliability standards established by NERC.

Calculating inadvertent interchange on an hourly schedule allows operators to react quickly to any issues that may arise, facilitating adjustments in real-time and helping to avoid larger systemic problems. Maintaining this level of oversight enables operators to effectively manage resources and provides transparency for reporting and regulatory compliance.
