Stanislaus County power outage caused by party decorations. What to know
With summer celebrations underway, Pacific Gas & Electric Company is warning residents about the safety risks associated with metallic balloons in California.
“Helium-filled metallic balloons can pose a serious public safety risk if they are not tied to a weight,” PG&E said in a May 14 news release, drifting into overhead power lines and causing outages.
In the first five months of 2026, the utility company saw 100-plus power outages related to the popular party decorations.
Those outages interrupted services to more than 46,000 customers, PG&E said.
Here’s how to display balloons safely while celebrating:
Why do balloons cause power outages?
Balloons can be made of rubbery latex or a durable, flexible polyester film such as Mylar.
Although Mylar doesn’t conduct electricity, shiny metallic balloons made with the plastic material have an external coating that conduct electricity, according to Silicon Valley Power in Santa Clara
“When the balloon’s conductive coating hits the active electrical line, this creates a momentary spike in electricity and short‑circuits the power line, resulting in potential outages, fires and damage to equipment,” Silicon Valley Power said.
Latex balloons can also cause power outages, but these are less common than outages caused by metallic balloons, New Orleans-based power company Entergy Corp. said.
Balloon strings can get wrapped up in power lines, pulling the lines together and resulting in outages.
Floating balloons are filled with lightweight gases such as helium, according to the National Aviation Academy.
“PG&E typically sees more balloon-related outages during graduation season, which is why the company is urging customers to take a few simple precautions before celebrating outdoors,” the utility company said in the release.
Did balloons cause power outage in Stanislaus County?
According to PG&E, Stanislaus County had on power outage caused by metallic balloons so far in 2026.
A total of 1,678 customers were affected, and the outage lasted 35 days.
Other California counties have also seen power outages due to metallic balloons in 2026, the utility company said.
Merced County has experienced four balloon-related outages so far in 2026, impacting 842 customers in total, PG&E said, while Fresno County reported 12 outages that collectively affected 2,780 customers.
Is releasing Mylar balloons against the law in California?
Under California law, it is illegal to release balloons outdoors that are made of electrically conductive material and that are filled with gas that is lighter than air.
Violating this rule for the first time is an infraction punishable by a fine of up to $100.
If you’re caught illegally releasing balloons twice, you could be charged with a misdemeanor.
What should I do if something gets caught in a power line?
PG&E encourages people to not use metallic balloons near electric lines and to not bundle them together.
Helium-filled metallic balloons should be tied down to a weight that is heavy enough to stop them from floating away.
“When possible, keep metallic balloons indoors. Never permit metallic balloons to be released outside, for everyone’s safety,” the electric company stated.
You should never attempt to remove balloons, kites or toys that are caught in power lines.
Instead, remain at a safe distance away from fallen power lines, which should be considered energized and extremely dangerous.
If you witness a fallen power line, you can call 911.
