4. You are a Balancing Authority Operator. A neighboring Balancing
Authority in the Interconnection suddenly has a 500 MW generator trip due to a
gener- ator ground. What part of the ACE equation, ACE = (NIA-NIS) - 10B (FA-

100% for the preceding 12-month period.
C. The average ACE for a defined 10-minute period must be within a limit
called L10.
