NERC TEST UPDATED ACTUAL EXAM QUESTIONS AND
CORRECT ANSWERS
Question 1.
What percentage of load gives a 1 Hz change in an island condition?
ANSWER
6-10% (Think 6-10 day island vacation)
Question 2.
If ACE is Zero but system Hz is off, what should a system operator do?
ANSWER
Nothing! ACE bias and interchange schedule will improve frequency
Question 3.
If ACE is Zero, why not adjust generation to help frequency?
ANSWER
Could overload equipment, this is a NERC violation
Question 4.
When restoring from blackout condition, what should be done with load?
ANSWER
All load breakers should be opened, load should be restored in a controlled manner not to
exceed 5% of current available gen
Question 5.
What's the point of COM-001?
ANSWER
Each TO, BA, RC and NERCNet Use Orgs need to have good comms
,Question 6.
Where do they need to have comms?
ANSWER
Internal, Between RC, TO and BA, Other RC, TO, BA and authorities
Question 7.
Where applicable comms should be ______ and _______ routed.
ANSWER
Redundant and Diversely routed, just in case something fails
Question 8.
How do we know comms will be good?
ANSWER
They will manage, alarm, test and/or actively monitor, especially emergency comm facilities
and equipment (non-routine equipment)
Question 9.
When can languages other than English be used?
ANSWER
Only for internal operation, Operation of the BES requires comms in English
Question 10.
What is required so operation during a loss of comms will be ensured?
ANSWER
Written operating instructions and procedures
Question 11.
What is the point of COM-002?
ANSWER
Ensure BA, TO, GO, and RC have comms and capability to use them for addressing emergency

In a clear, concise and definitive manner, using 3 part(way) communications
Question 14.
Who is required to create a blackstart restoration plan? Who approves it?
ANSWER
Transmission Operators; Its RC
Question 15.
When is the blackstart condition finished?
ANSWER
When the choice of the next load to be restored is not driven by frequency and voltage control

ANSWER
TO annually review the plan and report to RC
Question 19.
After a system modification is made, how long does the TO have to update restoration plans?
ANSWER
90 days
Question 20.
Where is a copy of the restoration plan required to be kept?
ANSWER
Main and backup control rooms
Question 21.
What must be done on the restoration plan every five years?
ANSWER
Analyze the plan through actual events, steady state and dynamic simulations or testing that
the plan can work as intended.

within operating limits?
ANSWER
Every 5 years
