Power was out for about 730 customers.

Because City Hall and Beverly Fire Department phone lines are down, anyone with a a potential emergency was asked to call 911 during the outage.

Power was restored at about 8:00 p.m.

Though the fire was close to a building in the area, only smoke got inside, no flames.

Due to frigid temperatures in the area, a shelter and nearby churches were open for anyone without power who needed to keep warm.
