Outage time is SAIDI: the average minutes a customer went without power across the year, storms and major events included. Outages/yr is SAIFI. The US median across all reporting utilities is 3 hours (178 minutes).
What these numbers do and do not say
SAIDI counts the minutes an average customer spent without power over the year, including storms and other major events. We rank on the figure that includes them, because excluding storms would describe a year nobody actually lived through.
Utilities report these numbers themselves, and smaller co-ops and municipal systems often serve rural territory where a single line fault affects a large share of customers. A high number is not automatically mismanagement — but it is still the power you did not have.
Utilities that filed no reliability data are left out entirely rather than counted as zero.
