NERC UPDATED SCRIPT 2026 PRACTICE
SOLUTIONS GRADED A+
● 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
● How often must a Blackstart Resource be verified at a minimum?
Answer: Once every 3 years
