BAL-002 R1 and NERC Glossary
The Responsible Entity experiencing a Reportable Balancing Contingency Event Shall:
1.1 - Within the Contingency Event Recovery Period of _________ (time) demonstrate recovery by returning its Reporting ACE to at least the value of __________ OR _________
15 minutes
Zero OR Pre-existing negative value if ACE was already negative
BAL-002 R1
1.1
Any subsequent Balancing Contingency Event that occurs during the Contingency Recovery Period shall _______ the required recovery amount by the _______ of said additional Balancing Contingency Event
reduce
magnitude (amount of additional ACE the subsequent event decreases ACE)
IE: 5 minutes after an event, ACE is still -100 MW. Additional event takes ace to -150 MW. To get out of the Balancing Contingency Event, I only need to get to -50 MW. Not 0.
BAL-002 R1
1.2 Document all Reportable Balancing Contingency Events using _______
CR Form 1
BAL-002 R1
1.3 The Balancing Authority shall deploy ________, withing system constraints, to respond to all Reportable Balancing Contingency Events
Contingency Reserve
BAL-002 R1 1.3.1
A Balancing Authority (BA) or Reserve Sharing Group is not subject to compliance with Reportable Contingency Recovery Period if what 4 things are true?
Reliability Coordinator (RC) Declared an Energy Emergency Alert Level
AND
Contingency Reserves are being utilized to mitigate an emergency in accordance with procedures.
AND
Contingency Reserve is < Most Severe Single Contingency (MSSC)
AND
RC has been notified of the above and BA has provided an ACE recovery plan with a set timeline.
BAL-002 R2
How much contingency reserve must a Balancing Authority (BA) or Reserve Sharing Group have on hand?
A value > Most Severe Single Contingency (MSSC)
BAL-002 R1 1.3.2
When would a Balancing Authority or Reserve Sharing Group not have to comply with the Contingency Event Recovery Period (when outside an already declared Energy Emergency Alert Level)?
Multiple Balancing Contingency Events occur that are defined as a single contingency event with MW > Most Severe Single Contingency Event (MSSC)

Most Severe Single Contingency
Contingency Reserve Recovery Period
BAL-002 R3
A Balancing Contingency Event that happens to occur during the Contingency Reserve Recovery Period has what effect on the Contingency Reserve Recovery Period time frame?
Resets the time requirement to recover contingency reserve
BAL-003-2 R1:
NERC assigns each BA a Frequency Response Obligation (FRO). Each BA must prove that their Frequency Response Measure (FRM) is equal to or less than the FRO assigned by NERC.
Therefore, as per above: (BAL-003-2 R2)
What part of the ACE equation must the BA set as less than (more negative) or equal to the FRO assigned by NERC so they don’t in trouble?
Frequency Bias
BAL-003 R3
If a BA is NOT receiving Overlap Regulation Service, and has a variable frequency bias, what must the frequency bias be set to at all times?
< 0 at all times
= or < Frequency Response Obligation (FRO) any time frequency deviates from 60 hz > dead band (+/- .036)
