According to INT-009, where should Attaining and Native Balancing Authorities account for Pseudo-Ties?

The correct answer is that Attaining and Native Balancing Authorities should account for Pseudo-Ties in the Actual Net Interchange term of their respective ACE (Automatic Generation Control) equations. This is because the Actual Net Interchange represents all inbound and outbound energy transfers between balancing authorities. Pseudo-Ties, which refer to the representation of resources in neighboring areas to support load in another area without using a physical transmission path, must be accurately reflected in the Actual Net Interchange to ensure that the balancing authorities can effectively manage and balance their energy resources.

Incorporating Pseudo-Ties in the ACE equations allows balancing authorities to account for the energy contributions from resources that are not directly located within their borders but are controlled in such a way that they affect the balancing area's net interchange. This ensures more accurate balancing, performance monitoring, and compliance with reliability standards.

The other options do not provide the appropriate framework for accounting Pseudo-Ties within the operational control of balancing authorities. Transaction logs, financial reports, and planning documents serve different purposes and do not directly impact the real-time operation and balancing of the electric grid in the same way the Actual Net Interchange does.
