Looks like a weather event. Perhaps the network was at it's most sensitive bushfire mitigation setting as a precaution. Time will tell. Possible scenario: Passing storm and lightning strikes caused two transmission lines to trip. Resulting in Loy Yang A having no connection to market so it trips to protect itself. Triggering rolling blackouts to further protect infrastructure.
