NERC RC EXAM ACTUAL EXAM 2026 | ALL QUESTIONS AND CORRECT ANSWERS |
GRADED A+ | VERIFIED ANSWERS | BRAND NEW VERSION!
Question 1

Correct Answer: C) 8-12 hours
Rationale: NERC standards generally expect station batteries to provide 8 to 12 hours of
backup power to critical protection and control equipment to allow sufficient time for the
restoration of AC power or the deployment of mobile generators.

timeframe to restore data exchange redundancy?
A) 30 minutes
B) 60 minutes
C) 2 hours
D) 12 hours
E) 24 hours
Correct Answer: C) 2 hours
Rationale: Per reliability standards, entities have a 2-hour window to restore redundant
data exchange capabilities to ensure the reliability of monitoring and control systems.

disturbance recovery period?
A) 15 minutes
B) 30 minutes
C) 60 minutes
D) 90 minutes
E) 120 minutes
Correct Answer: D) 90 minutes

Rationale: After a reportable disturbance, an entity has 15 minutes to recover its ACE.
Following that 15-minute recovery, they have an additional 90 minutes to restore their
contingency reserves to the required levels.
Question 8
How often is a Balancing Authority (BA) required to calculate and record its inadvertent
interchange?
A) Every 6 seconds
B) Every 10 minutes
C) Hourly
D) Daily
E) Monthly
Correct Answer: C) 60 minutes/hourly
Rationale: Inadvertent interchange—the difference between actual and scheduled flows—
must be calculated and recorded on an hourly basis to maintain interconnection balance.
Question 9
How often must a Balancing Authority provide MW-hour meter readings to adjacent Balancing
Authorities?
A) Every 10 minutes
B) Every 30 minutes
C) Hourly
D) Every 24 hours
E) Weekly
Correct Answer: C) 60 minutes/hourly
Rationale: To ensure accurate accounting of power flows, meter readings are exchanged
between adjacent BAs every hour.
Question 10
The Transmission Loading Relief (TLR) procedure, identifying levels and actions, must be
updated how often?
A) Every 15 minutes
B) Every 30 minutes
C) Hourly
D) Every 4 hours
E) As needed only
Correct Answer: C) 60 minutes/hourly
Rationale: TLR procedures are dynamic and must be updated hourly to reflect current
system congestion and the effectiveness of previous actions.

Question 11
How often is the hourly Available Transfer Capability (ATC) for the next 48 hours calculated?
A) Every 10 minutes
B) Every 30 minutes
C) Hourly
D) Daily
E) Weekly
Correct Answer: C) 60 minutes/hourly
Rationale: Short-term ATC is highly sensitive to system changes and must be recalculated
every hour for the immediate 48-hour window.
Question 12
During an EEA2 or EEA3 event, how often must the energy-deficient entity update the
Reliability Coordinator (RC)?
A) Every 10 minutes
B) Every 15 minutes
C) Every 30 minutes
D) Hourly
E) Only when the alert ends
Correct Answer: D) 60 minutes/hourly
Rationale: Continuous communication is required during energy emergencies; hourly
updates ensure the RC has the latest data to coordinate assistance.
Question 13
DOE-417 (Disturbance Reporting) should be completed within how many minutes of a
reportable event?
A) 15 minutes
B) 30 minutes
C) 60 minutes
D) 120 minutes
E) 24 hours
Correct Answer: C) 60 minutes
Rationale: Federal regulations (Department of Energy) require the DOE-417 form to be
filed within 60 minutes for major grid disturbances.
Question 14
A BA experiencing a loss of resources must submit a Request for Interchange (RFI) with a start
time no more than how far beyond the resource loss?
A) 10 minutes
B) 15 minutes
C) 30 minutes
