About this data

When PG&E de-energizes lines for wildfire risk, the shutoff's footprint appears on its outage map. Each record gives the event, its stage, the customers and Medical Baseline customers affected, the de-energization window and the estimated restoration, with the area as GeoJSON. It is empty between shutoffs.
