Today’s LiveWire Spotlight looks at the second version of the proposed Geomagnetic Disturbance (GMD) mitigation planning standard applicable only to Canadian entities. Once approved, TPL-007-3 will allow Transmission Planners and Planning Coordinators to define Benchmark and Supplemental GMD Events specific to Canadian geographical and geological characteristics.

The second draft of the Canadian Variance to TPL-007-3 and it supporting materials have been posted on the NERC website for a 45-day review and concurrent ballot. Comments must be returned to the project team and votes cast by November 15, 2018.
