CHICAGO (August 11, 2026) – ComEd crews are working to restore power to more
than 370,000 customers in the wake of a dangerous line of thunderstorms that swept
through northern Illinois this morning -- just hours after ComEd had completed
restoration of service to customers impacted by a severe storm on Sunday. Wind
gusts of up to 96 MPH -- and potential tornadoes -- downed trees, power lines and
utility poles throughout ComEd’s northern Illinois region.

Currently, there are more than 257,000 customers without electric service. Based on current conditions, ComEd estimates that approximately 80% of outages will be restored by noon on
Aug. 13 and approximately 99% by 11 p.m. on Aug. 15. “Nearly 3,000 ComEd employees and contractors are in the field assessing damage, repairing equipment and restoring service as safely and quickly as possible.

“Nearly 3,000 ComEd employees and contractors are in the field assessing damage,
repairing equipment and restoring service as safely and quickly as possible. While

crews and equipment, including poles, cable wire and transformers were pre-
positioned ahead of the storm, damage across the region is extensive,” said David

Perez, ComEd’s executive vice president and COO.
The largest impacts from Tuesday's storms were concentrated in ComEd's south
region, where crews are dealing with downed trees, broken poles, and damaged
power lines requiring extensive repairs. Hardest-hit areas include Homewood,
Chicago Heights, Lansing and Joliet, among others. The National Weather Service
is forecasting another round of storms for the ComEd region on Wednesday.
Restoration Priorities
ComEd crews work on restoring power to customers in the following order:
• Downed live wires or potentially life-threatening situations. High-voltage
transmission lines and equipment, to restore service to the largest number of
affected customers.
• Critical public health and safety facilities, like hospitals, police and fire stations,
and water treatment plants.
• Major distribution lines and high-density housing.
• Any remaining smaller neighborhoods and individual homes that have not been
restored by prior repair activities.

Historic Summer Storm Season
The August 9-11 storms mark the 19th major weather event affecting ComEd
customers in 2026 — the highest number in more than two decades. Illinois has now
recorded more tornadoes this year than any other state in the country. ComEd's
continued investments in grid modernization and smart grid technology have helped
avoid millions of potential outages over the past decade and strengthened the
company's ability to respond quickly when severe weather strikes.

Stay Safe
Public safety is paramount, and ComEd encourages customers to take the following
precautions:
• If a downed power line is spotted, immediately call ComEd at 1-800-EDISON1
