Outage mostly restored; one customer on backup power

SeaTac/Burien outage mostly restored with just one customer in Tukwila is on backup power.

Almost 9,800 customers lost power this morning at 4:30 a.m. in the SeaTac/Burien area.  Equipment failure at a substation caused multiple feeders to go offline. Power was quickly re-routed and most customers got their electricity back within the hour.

 One customer in Tukwila is on backup power and the cause for that is under investiation.
