More than 4,500 customers in Palo Alto lost power for about an hour on Friday afternoon in an outage that began shortly after 2 p.m. and that was caused by a Mylar balloon hitting power lines, according to the city.
The outage spanned a major portion of south Palo Alto west of Middlefield Road. This included homes and businesses in the Ventura, Barron Park and Charleston Meadows neighborhoods. It is affected several areas north of Oregon Expressway, including the California Avenue business district and the Evergreen Park and College Terrace neighborhoods, according to the Palo Alto Utilities outage map.
The outage was caused by a Mylar balloon that became entangled in power lines, according to Palo Alto Utilities. As of 2:55 p.m., power was restored to all impacted customers.
In a tweet, Palo Alto Utilities advised to the public to consider alternatives to Mylar balloons, which "are a major cause of power outages and should always be kept away from overhead power lines and utility equipment."
