Read the first 6 NERC Emergency Preparedness and Response flashcards as text

  1. A Geomagnetic Disturbance (GMD) poses a risk to the bulk electric system primarily by:

    Answer: Inducing quasi-DC currents in transmission lines that can saturate transformers and cause equipment damage

    GMDs induce geomagnetically induced currents (GICs) in long transmission lines, which can saturate transformer cores, cause overheating, and lead to widespread failures.

  2. NERC standard TPL-007 specifically addresses planning requirements for:

    Answer: Geomagnetic Disturbance (GMD) events

    TPL-007 requires transmission planners to assess the vulnerability of their systems to benchmark GMD events and develop mitigation strategies.

  3. Under NERC EOP-004, what types of events must be reported to NERC and applicable Regional Entities?

    Answer: Events meeting defined thresholds including disturbances, sabotage, unusual occurrences, and natural disasters affecting the BES

    EOP-004 requires reporting of events meeting defined thresholds covering disturbances, deliberate attacks, natural disasters, and other unusual occurrences affecting BES reliability.

  4. When a Transmission Operator declares an 'Energy Emergency Alert' (EEA) Level 3, it means:

    Answer: Firm load shedding is anticipated or in progress

    EEA Level 3 is the most severe level, indicating that firm load shedding (involuntary customer interruptions) is occurring or imminent.

  5. Which organization provides mutual aid coordination between utilities during large-scale grid emergencies in the US?

    Answer: The Edison Electric Institute (EEI) through the Mutual Assistance Program

    EEI coordinates the electric utility industry's mutual assistance program, which mobilizes crews and equipment from unaffected utilities to help restore power after major events.

  6. NERC standard EOP-011 addresses which emergency preparedness requirement for Balancing Authorities?

    Answer: Emergency operations plans with defined responsibilities and communication protocols

    EOP-011 requires Balancing Authorities to have documented emergency operations plans specifying responsibilities, communication protocols, and actions during grid emergencies.
