About 200 customers in the Western Addition and Laurel Heights areas of San Francisco were still without power Monday afternoon after two Mylar balloons damaged power lines.
At approximately 1:51 p.m., Pacific Gas and Electric and the Fire Department received a call about a power outage resulting from a possible blown transformer in the area, knocking out power to more than 6,500 customers.
PG&E said just after 4 p.m. that 197 customers were still without power. Power was supposed to be restored by 6 p.m., PG&E said.
As the Fire Department arrived at the scene they discovered that two Mylar balloons had come in contact with power lines at the corner of Hayes and Lyon streets and were causing a high-voltage wire to arc upwards.
According to a PG&E spokeswoman, the company is currently working to restore as many customers as possible, but does not have an estimated time when everyone’s service will be restored.
