Pacific Gas and Electric Warns of Public Safety Risks During Graduation Season

Strategic Insights -

As graduation ceremonies take place across Oakland, Pacific Gas and Electric Company (PG&E) is reminding customers of the dangers associated with helium-filled metallic balloons. These balloons can float away and come into contact with overhead power lines, causing widespread power outages and disrupting service to critical facilities such as hospitals, schools, and traffic lights.

Key Takeaways:

  • In the first five months of 2025, metallic balloons striking electric lines have caused over 130 power outages in PG&E's service area alone, disrupting service to more than 54,000 customers.
  • PG&E typically sees a spike in the number of outages caused by metallic balloons during the graduation season.
  • Metallic balloons have a silvery coating, which is a conductor for electricity, and can short transformers, cause power outages, and melt electrical wires.
  • A few years ago, a homecoming parade in the North Coast turned dark after a group of metallic balloons slipped away from a float and hit a power line, which came down energized, affecting over 2,700 customers.
  • To ensure safe graduation balloon celebrations, PG&E reminds customers to "Look Up and Live!" and follow important balloon safety tips, including secure tie downs, indoor celebrations, and reporting downed power lines immediately.

Statistics:

  • 130 power outages caused by metallic balloons in PG&E's service area in the first five months of 2025.
  • Over 54,000 customers disrupted by power outages caused by metallic balloons in the first five months of 2025.
