Status
A 45-day formal comment period and initial ballot for the standard, along with non-binding polls for the associated Violation Risk Factors and Violation Severity Levels, for TPL-007-4 – Transmission System Planned Performance for Geomagnetic Disturbance Events concluded at 8 p.m. Eastern, Monday, September 9, 2019.

Background
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. The third version of the standard adds a Canadian variance 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 Background Information. This project will address the directives issued by FERC in Order No. 851 to modify Reliability Standard TPL-007-3. FERC directed NERC to submit modifications to: (1) require the development and implementation of corrective action plans to mitigate assessed supplemental GMD event vulnerabilities (P 29); and (2) to replace the corrective action plan time-extension provision in Requirement R7.4 with a process through which extensions of time are considered on a case-by-case basis (P 54).
