More than 25,000 residents in Chicago's west suburbs were without power in Chicago after a communications tower fell on some power lines on Friday (August 8).

The incident impacted power company ComEd (Commonwealth Edison) after the tower fell near Schmale and St. Charles roads in Carol Stream about 11 am.

ComEd was able to fully restore power for residents by 8pm, reported ABC7, which said the incident impacted more than 25,000 customers in Wheaton, Carol Stream, Winfield, and Hanover Park.

ABC7 noted that the power outage occurred during a heatwave, as temperatures hit the 90's (°F, above 32°C), meaning residents were without air conditioning during this time.

No cause has been given by the company for the fall.

ComEd apologized to its customers on social media, noting that the tower that hit its transmission line is not owned by the company.

ComEd, a unit of Chicago-based Exelon Corporation, provides power to more than four million customers across northern Illinois, which is roughly 70 percent of the state’s population.
