NERC Test Questions With 100%Verified
AnswersA+GRADED(Guaranteed
Sucess)
What percentage of load gives a 1 Hz change in an island condition? - correct
answer...✔✔6-10% (Think 6-10 day island vacation)
If ACE is Zero but system Hz is off, what should a system operator do? - correct
answer...✔✔Nothing! ACE bias and interchange schedule will improve frequency
If ACE is Zero, why not adjust generation to help frequency? - correct answer...✔✔
Could overload equipment, this is a NERC violation
When restoring from blackout condition, what should be done with load? - correct
answer...✔✔All load breakers should be opened, load should be restored in a
controlled manner not to exceed 5% of current available gen
What's the point of COM-001? - correct answer...✔✔Each TO, BA, RC and NERCNet
Use Orgs need to have good comms
Where do they need to have comms? - correct answer...✔✔Internal, Between RC, TO
and BA, Other RC, TO, BA and authorities
Where applicable comms should be ______ and _______ routed. - correct answer...✔
✔Redundant and Diversely routed, just in case something fails
How do we know comms will be good? - correct answer...✔✔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? - correct answer...✔✔Only for
internal operation, Operation of the BES requires comms in English
What is required so operation during a loss of comms will be ensured? - correct
answer...✔✔Written operating instructions and procedures
What is the point of COM-002? - correct answer...✔✔Ensure BA, TO, GO, and RC
have comms and capability to use them for addressing emergency and that operators
are trained to use them
AGRADESOLUTIONS
,Who should a BA or TO notify if they are aware of any condition that could threaten
area reliability or when shedding load? - correct answer...✔✔Notify their RC and any
other potentially affected BA or TO
How should directives be issued by an RC, TO or BA? - correct answer...✔✔In a clear,
concise and definitive manner, using 3 part(way) communications
Who is required to create a blackstart restoration plan? Who approves it? - correct
answer...✔✔Transmission Operators; Its RC
When is the blackstart condition finished? - correct answer...✔✔When the choice of the
next load to be restored is not driven by frequency and voltage control
Who directs the procedure for restoring interconnection between Tos? - correct
answer...✔✔RC
What must be done prior to implementing changes in a restoration plan? - correct
answer...✔✔The parties invloved must be told of changes to their role and specific
tasks prior to implementation.
How often must the plan be confirmed given no changes were made? - correct
answer...✔✔TO annually review the plan and report to RC
After a system modification is made, how long does the TO have to update restoration
plans? - correct answer...✔✔90 days
Where is a copy of the restoration plan required to be kept? - correct answer...✔✔Main
and backup control rooms
What must be done on the restoration plan every five years? - correct answer...✔✔
Analyze the plan through actual events, steady state and dynamic simulations or testing
that the plan can work as intended.
How often must a Blackstart Resource verify it can meet real and reactive power
requirements of its cranking path and intial load? - correct answer...✔✔Every 5 years
How often must the location of loads required to control voltage and Hz in a blackstart
be verified within operating limits? - correct answer...✔✔Every 5 years
How often is the capability of generating resources required to control voltage and Hz in
a blackstart condition verified? - correct answer...✔✔Every 5 years
What should a TO use if the restoration plan cannot be executed? - correct answer...✔
✔Use its restoration strategies
AGRADESOLUTIONS
, Under what conditions can a TO resynchronize with its neighboring TO? - correct
answer...✔✔Only with RC approval or with the established procedures of the RC
What is the point of Blackstart Resource testing? - correct answer...✔✔To ensure the
resource is capable of me4eting the requirements of the restoration plan
How often must a Blackstart Resource be verified at a minimum? - correct answer...✔
✔Once every 3 years

answer...✔✔System restoration plan including coordination with RC and GO;
Restoration Priorities; Building of cranking paths; Synchronizng
How often and how much training is required for field switching personnel who are
included in the system restoration plan? - correct answer...✔✔Minimum 2 hrs every 2
years
When must a TO or GO participate in RC restoration drills, exercises or simulations? -
correct answer...✔✔As requested by the RC
What is a Blackstart Resource Agreement? - correct answer...✔✔This is an agreement
between a TO and GO that includes the terms and conditions of the use of the
Blackstart Unit; e.g. procedures, protocols, testing requirements
What is required by each GO for their Blackstart Resources? - correct answer...✔✔
Documented procuedures for starting each resource and energizing a bus
Who must a GO notify if a Blackstart Resource ability to perform its function is
changed? - correct answer...✔✔The TO who holds the agreement
What is the time requirement for a GO to notify its TO when a Blackstart Resource
capabilities are compromised? - correct answer...✔✔24 Hours
