On September 22, 2016 FERC approved NERC’s TPL-007-1 standard which establishes requirements for assessing transmission system performance during benchmark geomagnetic disturbance (GMD) events. 

Utility Planning Coordinators, Transmission Planners, Transmission Owners and Generation Owners have new mandatory responsibilities under the standard. In particular, transmission owning utilities are now required to analyze and assess the performance of their transmission systems under a GMD benchmark planning event.

With the approval of TPL-007-1, the industry now has the long awaited regulatory certainty it needs to plan and possibly modify transmission systems to withstand the effects of GMD.
