7:11 AM: Thanks for the texts. More than 3,700 homes and businesses have lost power, including Westwood, South Delridge, and White Center. No hint yet of the cause. Updates to come.
7:28 AM: No indication yet what caused this. Note that the outage zone includes parts of Roxbury and 16th SW, both arterials, with signals, so if you travel through an intersection that’s affected, it’s a four-way stop. Also remember that SCL’s restoration estimates are just guesses. (Added: The latest guess has already changed dramatically, from 2 pm to 8:54 am.)
7:51 AM: We have one report that power’s back. The SCL map lags so we won’t get the full picture for a bit.
8:01 AM: Map shows one pocket remains, almost 400 customers in the Greenbridge area. We’ll update later when we find out the cause. (So far, SCL has attributed it to an “underground issue.”)
8:15 AM: Checking the archives – this outage footprint, and cause, is similar to this December outage. We’re following up on that.
6 PM: City Light spokesperson Julie Moore responded: “Today’s outage was due to a switch failure that caused a substation feeder breaker to lock out. It was the same breaker as the Dec. 12 incident, so that’s why we saw a similar footprint. However, it was a different switch in a different location on the feeder that failed this time.”
