Observed Effects of Geomagnetic Disturbances From Wide Area Monitoring System

A distributed sensor network has been deployed in over 700,000 homes so far. The sensor network identified several grid impacts during a May 10, 2024 solar storm. The storm produced geomagnetic disturbances (GMD) on many grid networks. This presentation will share measurements made by the sensor network and lessons learned from the event. Some of the lessons learned contradict traditional understanding of GMD events.
