NERC Reliability Standard available for review

February 5, 2015

The following North American Electric Reliability Corporation (NERC) Reliability Standard is available for review:

  • TPL-007-1 Transmission System Planned Performance for Geomagnetic Disturbance Event

This standard requires applicable entities to conduct initial and on-going vulnerability assessments of the potential impact of benchmark geomagnetic disturbance ("GMD") events on the bulk electric system equipment and the bulk electric system as a whole. This applies to the planning coordinator, transmission planners, transmission owners and some generator owners.

The deadline is May 28, 2015 to apply to the Ontario Energy Board (OEB) for a review of this standard.

The standards have been posted on the OEB Review of a New or Amended Reliability Standard section
