NERC RC BAL-005 (NERC Reliability Coordinator Examination) | Actual
Questions and Answers Latest Updated 2025/2026 (Graded A+)
What is the purpose of BAL-005? - ✔✔Establishes requirements for BA AGC necessary to calculate ACE
& deploy regulating reserves.
Ensures that all facilities & load electrically synchronized to the interconnection are included within the
metered boundary of a BA
What is a Balancing Authority (BA)? - ✔✔The responsible entity that integrates resource plans ahead of
time, maintains load-interchange-generation balance within a BA area & supports interconnection
frequency in real time.
What mode of AGC does NERC require BAs to operate in? - ✔✔Tie Line Bias
What is 'Regulating Capacity'? - ✔✔portion of operating reserve which is under AGC control.
What is "Regulation Service"? - ✔✔Process whereby 1 BA contracts to provide corrective response to all
or a portion of the ACE of another BA.
Controlling utility assumes the obligation of meeting all applicable control criteria as specified by NERC.
What is "Overlap Regulation Service"? - ✔✔A method of providing regulation service in which the BA
providing the regulation service incorporates another BA's actual interchange, frequency response &
schedules into providing BAs AGC/ACE equation.
What is "Supplemental Regulation Service"? - ✔✔A method of providing regulation service in which the
BA providing the regulation service receives a signal representing all or a portion of the others BA ACE.
The BAs involved will implement the service as a Dynamic Schedule.
