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

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
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

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

What should a TO use if the restoration plan cannot be executed? - correct answer.Use
its restoration strategies
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

answer.Once every 3 years
Name two requirements when testing a Blackstart Resource: - correct answer.Ability to
start with no BES support and remain energized without the rest of the system; The
ability to energize a bus
What is the frequency that system restoration training for operators is required? -
correct answer.Annually
What is the purpose of annual operator system restoration training? - 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

answer.Name of Resource, unit tested, date of test, duration of test, time required to
start, and any test requirements not met
