Status
Final ballots for TPL-007-3 (Canadian Variance) – Transmission System Planned Performance for Geomagnetic Disturbance Events and the associated Implementation Plan concluded at 8 p.m. Eastern, Monday, December 10, 2018.

Reliability Standard TPL-007-3 adds a Variance for Canadian entities. The Canadian Variance replaces, in its entirety, Requirement R7, Part 7.3 of the continent-wide standard for Canadian entities and adds an alternate methodology for GMD Vulnerability Assessments, as described in Attachment 1-CAN. None of the continent-wide Requirements have been changed.

 

Background
Reliability Standard TPL-007-2 – Transmission System Planned Performance for Geomagnetic Disturbance Events was approved by industry in 2017 and filed with the Federal Energy Regulatory Commission on January 22, 2018 and the Canadian authorities on February 27, 2018. The first version of the standard, TPL-007-1, requires entities to assess the impact to their systems from a defined event referred to as the “Benchmark GMD Event." The second version of the standard adds new Requirements R8, R9, and R10 to require responsible entities to assess the potential implications of a “Supplemental GMD Event" on their equipment and systems in accordance with the FERC's directives in Order No. 830. On June 13, 2018, the Standards Committee approved a SAR and appointed a standard drafting team (SDT) to make Canadian-specific revisions to TPL-007-2.

Standard(s) Affected: TPL-007-2 – Transmission System Planned Performance for Geomagnetic Disturbance Events

Purpose/Industry Need
The purpose of this project is to enable the option for Canadian Registered Entities to leverage operating experience, observed GMD effects, and on-going research efforts for defining alternative Benchmark GMD Events and/or Supplemental GMD Events that appropriately reflect their specific geographical and geological characteristics. This project also addresses regulatory frameworks specific to Canadian jurisdictions.
