What percentage of load 6-10% (Think 6-10 day island vacation)
gives a 1 Hz change in an
island condition?
If ACE is Zero but systemNothing! ACE bias and interchange schedule will
Hz is off, what should aimprove frequency system operator do?
If ACE is Zero, why not Could overload equipment, this is a NERC violation
adjust generation to help
frequency?
When restoring from All load breakers should be opened, load should be
blackout condition, what restored in a controlled manner not to exceed 5% of
should be done with load? current available gen
What's the point of Each TO, BA, RC and NERCNet Use Orgs need to have good
COM001? comms
Where do they need to have Internal, Between RC, TO and BA, Other RC, TO, BA and
comms? authorities
Where applicable comms Redundant and Diversely routed, just in case something fails
should be ______ and
_______ routed.
They will manage, alarm, test and/or actively monitor, especially
How do we know comms
emergency comm facilities and equipment
will be good?
(non-routine equipment)
,When can languages other Only for internal operation, Operation of the BES requires
than English be used? comms in English
What is required so Written operating instructions and procedures
operation during a loss of
comms will be ensured?
What is the point of Ensure BA, TO, GO, and RC have comms and capability to
COM002? use them for addressing emergency and that operators are
trained to use them
Who should a BA or TO Notify their RC and any other potentially affected BA or TO
notify if they are aware of
any condition that could
threaten area reliability or
when shedding load?

issued by an RC, TO or BA? communications
Who is required to create a Transmission Operators; Its RC
blackstart restoration plan?
Who approves it?
When is the blackstart When the choice of the next load to be restored is not
condition finished? driven by frequency and voltage control
