What s the difference between a rotational outage and an emergency or unplanned outage?
Unplanned or emergency storm-related or accident-caused power outages normally last only a few minutes but can extend to hours. The average Idaho Power customer is without power less than two hours during an entire year. Rotational outages are outages caused by a short power supply, loss of a generating facility or loss of a major transmission line. Rotational outages generally last about two hours, depending on circumstances.
