What happened

In downtown Minneapolis, an underground electrical transformer failed near Ninth Street and Hennepin Avenue, and the Minneapolis Fire Department said a transformer likely exploded. Firefighters responded to reports of an explosion and smoke. Some nearby buildings lost power. The department said there was no damage and no injuries. Xcel Energy said it was working to restore power to 22 customers in the downtown area after the outage began at 4:34 p.m.

Contributing factors

Xcel Energy said an underground electrical transformer failed. No further cause is reported.

Lessons learned

  1. Treat reports of explosion and smoke at urban electrical equipment as a possible transformer failure until the utility confirms the failed element.
  2. Keep outage maps current so the number of customers affected and the start time are clear while restoration is under way.
  3. Coordinate fire-service response with the network operator when power is lost at neighbouring buildings and no fire damage is found.
