NERC NERC Emergency Preparedness and Response 1 — Questions and Answers
Question 1: Which NERC standard requires Balancing Authorities and Transmission Operators to have emergency operations plans?
- EOP-001 (Correct answer)
- EOP-005
- EOP-011
- IRO-006
Correct answer: EOP-001
EOP-001 requires Balancing Authorities and Transmission Operators to have plans for managing operations during emergencies, including personnel and communication protocols.
Question 2: NERC EOP-005 governs which critical grid restoration capability?
- Load shedding procedures during frequency events
- System restoration plans including black start capability (Correct answer)
- Emergency fuel supply agreements for generators
- Cyber incident response procedures
Correct answer: System restoration plans including black start capability
EOP-005 requires transmission operators and balancing authorities to have system restoration plans and verify black start resource capability.
Question 3: What is a 'Black Start' resource in the context of NERC EOP-005?
- A generator that automatically trips offline during voltage depression
- A generating unit capable of starting without an external power source to help restore the grid (Correct answer)
- A backup SCADA system activated during cybersecurity incidents
- An emergency load that must be shed first during grid stress
Correct answer: A generating unit capable of starting without an external power source to help restore the grid
A black start resource can energize transmission lines and pick up load without requiring external power, enabling grid restoration after a blackout.
Question 4: Under NERC EOP-006, what coordination is required during a wide-area disturbance?
- Generator owners must submit outage reports within 1 hour
- Reliability Coordinators must coordinate with each other during system restoration (Correct answer)
- Transmission owners must de-energize all lines above 230 kV
- Balancing Authorities must suspend energy market transactions
Correct answer: Reliability Coordinators must coordinate with each other during system restoration
EOP-006 requires Reliability Coordinators to have procedures for coordinating system restoration across their areas and with neighboring RCs.
Question 5: NERC's 'Under-Frequency Load Shedding' (UFLS) program is designed to:
- Prevent generation from interconnecting at low system frequencies
- Automatically disconnect controlled amounts of load when system frequency drops dangerously low (Correct answer)
- Alert operators when generators are operating below rated speed
- Reduce customer bills during frequency excursion events
Correct answer: Automatically disconnect controlled amounts of load when system frequency drops dangerously low
UFLS automatically sheds load in controlled blocks when frequency drops below set thresholds, preventing a total system collapse.
Question 6: Which NERC standard addresses under-voltage load shedding (UVLS) requirements?
- PRC-006
- PRC-010 (Correct answer)
- PRC-023
- EOP-003
Correct answer: PRC-010
PRC-010 requires transmission planners and planning coordinators to ensure UVLS schemes are coordinated and effective in preventing voltage collapse.
