NERC Emergency Operations Exam | Actual Questions and
Answers Latest Updated 2026/2027 (Graded A+)
•
What two things typically used to describe an emergency situation?
i. - ✔✔1) insufficient generation
ii. 2) SOL/IROL violation imminent or occurred
•
SO should maintain system connectivity to interconnection to maximize reliability (unless remaining
connected endangers BES) for capacity emergency by doing these 3 things:
i. - ✔✔1) postponing equipment maintenance
ii. 2) reducing load
iii. 3) initiating voltage reduction (on load @ dist. level)
•
SO should monitor these two things during load shed to ensure they don't get too high:
i. - ✔✔1) voltage
ii. 2) frequency
•
How long do RCs have to review a TOP and BA submitted Operating Plan to mitigate operating
emergencies?
- ✔✔30 days
•
Who does the RC notify after recieving an emergency notification from their TOP or BA? Within what
timeframe?
- ✔✔All BA and TOP in their area, as well as all other RCs via the RCIS within 30 min
•
Who can initiate an EEA?
- ✔✔RC (BA and LSE can submit requests)
•
If BA cannot comply with CPS and DCS it shall do these 6 things:
i. - ✔✔1) deploy all gen
ii. 2) deploy all operating reserve
iii. 3) Interrupt interruptible load + exports
iv. 4) Request emergency help from BAs
v. 5) declare Energy Emergency through
vi. 6) reducing load
•
2 common situations for initiating an EEA:
, i. - ✔✔1) LSE is or expects to be unable to provide energy requirements
ii. 2) LSE cannot schedule generation due to ATC/TLR limitations
•
EEA 1
- ✔✔All available resources in use
•
Circumstances for EEA 1
- ✔✔- BA, RSG, LSE concerned about sustaining required Contingency Reserves
•
- Non-firm wholesale energy sales curtailed
•
EEA 2
- ✔✔Load management procedures in effect (becomes an Energy Deficient Entity - EDE)
•
Circumstances EEA 2
- ✔✔In which EEA where EDE no longer provide customers expected energy; will not shed
firm load
•
- public appeals
- voltage reduction
- Interruption of non-firm loads
- Demand-side management
- Utility Load conservation
•
Min update time by EDE to the RC in an EEA 2 & 3
- ✔✔60 min
•
EDE actions prior to an EEA3
i. - ✔✔- all gen online
ii. - purchases made regardless of $
iii. -non-firm sales recalled
iv. - Interruption of non-firm loads
v. - Demand-side management - Operating reserves all/below min used
•
EEA 3
- ✔✔Firm load interruption imminent or in progress
