NERC TEST ACTUAL FINAL EXAM | WITH COMPLETE QUESTIONS AND ANSWERS |
2025/2026 LATEST UPDATED | 100 % RATED AND VERIFIED SOLUTIONS | GET AN A+
What percentage of load gives a 1 Hz change in an island condition? - (ANSWER)6-10% (Think 6-10
day island vacation)
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
If ACE is Zero, why not adjust generation to help frequency? - (ANSWER)Could overload equipment,
this is a NERC violation
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
What's the point of COM-001? - (ANSWER)Each TO, BA, RC and NERCNet Use Orgs need to have
good comms
Where do they need to have comms? - (ANSWER)Internal, Between RC, TO and BA, Other RC, TO,
BA and authorities
,Where applicable comms should be ______ and _______ routed. - (ANSWER)Redundant and Diversely
routed, just in case something fails
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)
When can languages other than English be used? - (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? - (ANSWER)Written operating
instructions and procedures
What is the point of COM-002? - (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
Who should a BA or TO notify if they are aware of any condition that could threaten area reliability or
when shedding load? - (ANSWER)Notify their RC and any other potentially affected BA or TO
How should directives be issued by an RC, TO or BA? - (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? - (ANSWER)Transmission
Operators; Its RC
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
Who directs the procedure for restoring interconnection between Tos? - (ANSWER)RC
What must be done prior to implementing changes in a restoration plan? - (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? - (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? -
(ANSWER)90 days
Where is a copy of the restoration plan required to be kept? - (ANSWER)Main and backup control
rooms
, 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.
How often must a Blackstart Resource verify it can meet real and reactive power requirements of its
cranking path and intial load? - (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? - (ANSWER)Every 5 years
How often is the capability of generating resources required to control voltage and Hz in a blackstart
condition verified? - (ANSWER)Every 5 years
What should a TO use if the restoration plan cannot be executed? - (ANSWER)Use its restoration
strategies
Under what conditions can a TO resynchronize with its neighboring TO? - (ANSWER)Only with RC
approval or with the established procedures of the RC
What is the point of Blackstart Resource testing? - (ANSWER)To ensure the resource is capable of
me4eting the requirements of the restoration plan
