NERC Test Questions - Exam Questions & Verified Answers
What percentage of load gives a 1 Hz change in an island 6-10% (Think 6-10 day island vacation)
condition?
If ACE is Zero but system Hz is off, what should a system Nothing! ACE bias and interchange schedule will improve frequency
operator do?
If ACE is Zero, why not adjust generation to help Could overload equipment, this is a NERC violation
frequency?
When restoring from blackout condition, what should be All load breakers should be opened, load should be restored in a controlled manner
done with load? not to exceed 5% of current available gen
What's the point of COM-001? Each TO, BA, RC and NERCNet Use Orgs need to have good comms
Where do they need to have comms? Internal, Between RC, TO and BA, Other RC, TO, BA and authorities
Where applicable comms should be ______ and _______ Redundant and Diversely routed, just in case something fails
routed.
How do we know comms will be good? They will manage, alarm, test and/or actively monitor, especially emergency comm
facilities and equipment (non-routine equipment)
When can languages other than English be used? Only for internal operation, Operation of the BES requires comms in English
What is required so operation during a loss of comms will Written operating instructions and procedures
be ensured?
What is the point of COM-002? Ensure BA, TO, GO, and RC have comms and capability to use them for
addressing emergency and that operators are trained to use them
Who should a BA or TO notify if they are aware of any Notify their RC and any other potentially affected BA or TO
condition that could threaten area reliability or when
shedding load?
How should directives be issued by an RC, TO or BA? In a clear, concise and definitive manner, using 3 part(way) communications
Who is required to create a blackstart restoration plan? Transmission Operators; Its RC
Who approves it?
When is the blackstart condition finished? When the choice of the next load to be restored is not driven by frequency and
voltage control
