Who is responsible for confirming the interchange schedule with the sending Balancing Authority?

The responsibility for confirming the interchange schedule with the sending Balancing Authority falls to the receiving Balancing Authority. This is crucial because the receiving Balancing Authority must ensure that they have adequate resources and agreements in place to accept the scheduled energy transfer. Their confirmation is integral to maintaining system reliability and ensuring that both parties are aligned on the terms of the energy exchange.

The process involves communication between the Balancing Authorities to affirm that the scheduled exchanges are confirmed, that the operational capabilities are in place, and that the associated tariffs and agreements are adhered to. This confirmation helps in managing flow limits and keeping the grid balanced, as inconsistencies could lead to operational challenges or even grid disturbances.

In this context, while other entities like the Primary Scheduling Entity, tag authority, and Transmission Service Provider play important roles in the scheduling and transmission process, the ultimate responsibility for confirming the specific interchange details and ensuring operational readiness lies with the receiving Balancing Authority.
