1. Time error correction: 60 +/- .02 Hz
2. ACE calculation frequency: Every 6 seconds
3. CPS1 measures how well a BA controls its generation and load management
programs to support interconnection frequency over a ___ period.: Rolling 1 year
4. A BA's BAAL cannot be exceeded for more than: 30 minutes
5. CPS1 minimum compliance level: CPS1 >= 100% , which is calculated and evaluated monthly
6. Contingency reserve requirements: Contingency reserves must be greater than or equal to the
most severe single contingency (MSSC).
7. Balancing contingency event can include a series of events separated by ___
or less: 1 minute
8. BAL-002: Reportable balancing contingency event: Results in MW loss described as:

ities for redundant functionality at least once every ______.: 90 days
