NERC TEST LATEST ACTUAL EXAM WITH VERIFIED
QUESTIONS & CORRECT ANSWERS
Question 1.

ANSWER
Generation, controllable load resources, coordinated adjustments to Interchange Schedules
Question 2.
What are the event reporting limits of loss of firm load?
ANSWER
Loss of firm load for 15 minutes or more, >300 MW for entities with >3000 MW in the previous
or > 200 MW for all other entitites

What is the most critical factor of a very long transmission power line with remote generation?
ANSWER
SOLs and IROLs most limiting factor comes from angle stability limitations as those drive the
power flow

ANSWER
> 2000 MW loss within one minute in the WECC or EAST, >1000MW in ERCOT or Quebec
Question 8.
What is given to each BA and RC to ensure the reliability of its respective area?
ANSWER
Responsibility and clear decision-making authority to take watever actions are needed, and
they shall exercise specific authroity to alleviate capacity and energy emergencies
Question 9.
How often is the capability of generating resources required to control voltage and Hz in a blackstart
condition verified?
ANSWER
Every 5 years
Question 10.
If multiple generators are lost, in what time frame will they be considered one contingency?
ANSWER
They must trip within 1 minute to be considered a single contingency
Question 11.
How often must the plan be confirmed given no changes were made?
ANSWER
TO annually review the plan and report to RC
,Question 12.
How often is ACE calculated?
ANSWER
At least every 6 seconds
Question 13.
What is spinning reserve?
ANSWER
Unloaded generation that is online and frequency responsive
Question 14.
How many days of training and drills using realistic simulations of system emergencies must a TO or
BA participate in yearly?
ANSWER
32 hours of training/year
Question 15.
What should a BA do if a factor affecting Frequency Bias is changed?
ANSWER
Review the Bias Setting and make necessary changes
Question 16.
Shared unit, fixed response. How is bias setup?
ANSWER
The Host BA, holding the Unit, will incorporate the droop into its equation for all. The other
BA(s) do not include the droop.
Question 17.
BA serving native load minimum frequency bias is based on...
ANSWER
The monthly average Frequency Bias is at least 1% of the BA estimated yearly peak demand
per .1 Hz (Load = 1 % demand; No Load = 1 % Gen)
, Question 18.
Name 5 things required to support a backup control centers functionality:
ANSWER
Tools and applications giving BES situational awareness; Data comms; Voice comms; Power
souce; Physical and cyber security
Question 19.
How often are CPS1 and CPS2 calculated and evaluated?
ANSWER
Monthly
Question 20.
What is the purpose of the Event Reporting standard?
ANSWER
Improved the reliability of the BES by requiring event reporting
Question 21.
By what means does an RC notify other RCs of a declared EEA?
ANSWER
The RCIS - Reliability Coordinator Information System
Question 22.
What two things must be included in the GO Blackstart Resource biannual training?
ANSWER
The system restoration plan including coordination with the TO; The procedures associated
with the Blackstart Resource Agreement
Question 23.
If a TO restoration plan does not work with the RC or neighboring TO what must be done?
ANSWER
The RC will inform the TO of the conflict with stated reasons within 30 days of receiving the
plan
