ComEd Continues Around-the-Clock Effort to Restore Power to Every Customer Affected by Derecho

Power restored to more than 95 percent of customers following historic storm

CHICAGO (Aug. 14, 2020) – ComEd has restored power to more than 721,000, or 95 percent, of the families and businesses affected by the derecho that swept across all of northern Illinois and brought hurricane force winds with gusts higher than 90 miles per hour, extensive lightning, golf ball-sized hail and 14 confirmed tornados in communities that ComEd serves. The number of ComEd customers out of service has dropped to under 35,000.

ComEd continues to focus its restoration efforts on the most highly impacted areas and vulnerable customers. With more than 3,300 ComEd employees, contractors and mutual assistance workers working nonstop, the energy company remains on track to restore power to every customer affected by the derecho by Saturday.

"As we near the late stages of the restoration process after this very destructive storm, the work that remains to rebuild and repair the system is extremely labor-intensive," said Terry Donnelly, president and COO of ComEd. "Thanks to the work our crews continue to do around the clock to restore customers as quickly and safely as possible, we've achieved historic restoration times, with over 540,000 customers restored within a day of the storm, the fastest restoration of half a million customers in the company's history."

Hundreds of customers are being restored each hour. Outages in areas where tornados or other intense storm events occurred may take longer to restore.

Power grid investments by ComEd since 2012 significantly lessened the impact of the derecho. These investments included infrastructure upgrades, storm hardening and "distribution automation" – technology that automatically detects outages and reroutes power around problem areas to restore customers' power. If not for these enhancements, the derecho would have caused about 1.5 million customer outages, or 700,000 more outages than occurred, ComEd estimates.

ComEd offers the following tips and information for customers to stay safe following severe weather:

  • If you encounter a downed power line, immediately call ComEd at 1-800-EDISON1 (1-800-334-7661) or go to to report the location. Spanish-speaking customers should call 1-800-95-LUCES (1-800-955-8237).
  • Never approach a downed power line. Always assume a power line is energized and extremely dangerous.
  • In the event of an outage, do not approach ComEd crews working to restore power to ask about restoration times. Crews may be working on live electrical equipment and the perimeter of the work zone may be hazardous.

ComEd urges customers to contact the company immediately if they experience a power outage. Customers can text OUT to 26633 (COMED) to report an outage and receive restoration information, and can follow the company on Twitter @ComEd or on Facebook at Customers can also call 1-800 EDISON1 (1-800-334-7661), or report outages via the website at Spanish-speaking customers should call 1-800-95-LUCES (1-800-955-8237).
