The dataset includes daily power outage occurrences derived from the NOAA storm events database at state-level for the contiguous United States. Days containing an outage are denoted with ones, while non-outage days are denoted with zeros. It also includes the NOAA event type associated with each day, the grouped hazard type, and the main TSO operating within each state. Leap days have been excluded. Event types are the first event type associated with an outage on a given day, or for days with no outages, the first event type for that day.
