Answer each one before you open the explanation. On the exam there's no explanation, and you have about 77 seconds a question on RC and BT, 90 on TO and BI.
In which Interconnection may a Balancing Authority include an Automatic Time Error Correction term in its Reporting ACE equation?
- A. the Eastern Interconnection
- B. the Quebec Interconnection
- C. the Western Interconnection
- D. the ERCOT Interconnection
Show the answer
Answer C the Western Interconnection
NERC's definition states that Automatic Time Error Correction applies only in the Western Interconnection. In any other Automatic Generation Control mode, and in the other three Interconnections, the term is zero.

A Balancing Authority in a multiple Balancing Authority Interconnection keeps finding small errors in the scan rate data feeding Reporting ACE, and its operators are starting to distrust the displayed value. What does BAL-005-1 require it to have?
- A. an immediate transfer to manual control until the errors clear
- B. a backup Reporting ACE calculated from revenue meters
- C. a monthly error report to the Reliability Coordinator
- D. an Operating Process to identify and mitigate the scan rate errors
Show the answer
Answer D an Operating Process to identify and mitigate the scan rate errors
R6 requires a Balancing Authority inside a multiple Balancing Authority Interconnection to implement an Operating Process that identifies and mitigates errors affecting the accuracy of the scan rate data used in Reporting ACE. The other three may be sensible local practices, but none of them is what the standard obliges the Balancing Authority to have.
