A handful of metallic party balloons turned a festive spring weekend into an unexpected blackout for thousands of Valley residents, after stray Mylar balloons floated into overhead power lines and cut electricity across the Phoenix area. The run-ins with the lines triggered separate outages in Chandler and Peoria, briefly knocking out power to homes and businesses during prime weekend hours. Crews got the lights back on quickly, but the incidents were a not-so-gentle reminder that a cheap party favor can cause some very expensive headaches.
According to 12News, Arizona Public Service says two separate balloon strikes over the weekend knocked out electricity to more than 8,700 homes and businesses across the Valley. APS reported that a cluster of metallic, helium-filled Mylar balloons in Chandler cut power to roughly 6,000 customers, while another balloon contact in Peoria affected about 2,700 customers. The utility said crews restored power quickly in both cities and noted that warmer weather has brought more outdoor gatherings where helium-filled balloons are floating around.
APS warns that Mylar balloons are coated with a metallic film that conducts electricity and can trigger a short circuit or power surge strong enough to melt wires, spark fires, and damage equipment, APS says. In its safety guidance, the utility recommends keeping balloons indoors whenever possible, always securing metallic balloons with a weight or tether, and puncturing and fully deflating them before throwing them away. APS also urges anyone who spots a balloon tangled in power lines to stay clear and report the hazard through its outage hotline or online outage map.
Where outages hit and how crews responded
In Chandler, APS said crews had power restored within about an hour of the balloon strike. In Peoria, service came back even faster, in roughly a minute, according to 12News. Officials said the episodes led to scattered, short-lived outages rather than a single, large-scale failure, and no injuries were reported. Even so, the brief blackouts disrupted businesses and highlighted how everyday celebration gear can turn into operational trouble as outdoor events ramp up.
How to avoid another blackout
APS advises residents to always assume power lines are energized, to stay at least 100 feet away from any lines and to report tangled balloons or other hazards by calling (602) 371-3680 or (855) 688-2437 or by visiting its outage center. The utility’s safety materials include a demonstration video and a reminder that many balloon-related outages happen during busy spring graduation and celebration seasons. Keeping metallic balloons tethered, weighed down or indoors can prevent service interruptions and spare crews a needless safety risk…
