Who is responsible for transitioning arranged interchange to confirmed interchange?

The sink Balancing Authority is responsible for transitioning arranged interchange to confirmed interchange. This role involves managing the physical delivery of electricity and ensuring that the interchange transactions are reflected accurately in the balancing authority area. The sink Balancing Authority verifies that the agreed-upon transactions can be fulfilled and confirms them to facilitate reliable system operations.

In this context, the primary scheduling entity typically initiates the process of arranging the interchange, but it is the sink Balancing Authority that plays the critical role in finalizing and confirming these arrangements to ensure that all operational and reliability standards are met. This confirmation process is essential for maintaining the integrity of the electricity grid and ensuring that power flows as planned, ultimately supporting overall grid reliability.

Other entities such as the Transmission Service Provider and the Reliability Coordinator have important roles in managing transmission services and overseeing grid reliability, but they do not directly confirm the interchange. Their functions support broader operational and reliability goals rather than the specific task of confirming interchange transactions.
