In an Interchange Transaction, with whom must Intermediate Balancing Authorities agree on Composite Confirmed Interchange?

In an Interchange Transaction, the Intermediate Balancing Authorities must reach an agreement on Composite Confirmed Interchange with both the Sink and Source Balancing Authorities. This requirement arises from the nature of the interchange process, which involves the exchange of electricity from one balancing authority area to another. The Source Balancing Authority is responsible for the generation and supplying of power, while the Sink Balancing Authority is the recipient of that power.

To maintain reliability and accuracy in the operation of the grid, it is essential for all parties involved to have a clear and accurate understanding of the quantity of power being exchanged. This agreement also ensures that all operators are aligned with the scheduled transactions, appropriately managing flows and any implications for system stability or planning. Consequently, the confirmation process is crucial in facilitating compliance with regulatory standards and operational protocols, making it mandatory for the Intermediate Balancing Authorities to coordinate with both the Source and Sink Balancing Authorities.
