Hundreds of customers were waiting for their electricity to go back on Saturday afternoon after a Mylar balloon caused a power outage to 2,000 Roscoe Village residents during the kick-off of the popular outdoor fest, Retro on Roscoe.
Power to about 2,000 customers was initially knocked out shortly before noon after a Mylar balloon came in contact with electric wires at Cornelia and Western, according to ComEd spokeswoman Alicia Zatkowski.
"We remind people not to let the balloons go, but someone did," she said.
But one hour later, power to 70 percent of the affected customers was been restored, leaving about 700 in the dark. Zatkowski said.
The outages were initially reported within the boundary of Addison to Roscoe and Ravenswood to Western, Zatkowski said.
No injuries were reported, according to Zatkowski.
A fest representative on the scene said the event would go on with or without power, thanks to the help of generators.
Retro on Roscoe, 2000 W. Roscoe St., is scheduled to begin at noon and end at 10 p.m. on Saturday and Sunday.
