What equipment must Balancing Authorities use to accurately account for inadvertent interchange?

Balancing Authorities are responsible for maintaining the reliability of the power system by ensuring that supply and demand are balanced. To accurately account for inadvertent interchange, which refers to the unscheduled transfers of power between balancing areas, reliable metering equipment is essential.

This metering equipment provides precise measurements of power flows, generation output, and loads. It enables Balancing Authorities to monitor real-time data and maintain an accurate assessment of their interchange with neighboring entities. By utilizing reliable metering, they can ensure that any inadvertent interchanges are identified promptly, allowing for rectification and maintaining system integrity.

While regular digital logs, manual records, monthly consumption reports, and basic voltage analyzers may play supportive roles in system operations, they do not provide the level of precision in measuring power flows that reliable metering equipment delivers. This makes it the necessary choice for Balancing Authorities when it comes to accounting for inadvertent interchange accurately.
