Ameren Illinois Storm Update

9:30 a.m., Friday, June 19, 2026

Summary:

Ameren crews, support personnel and contractors are nearing completion of electric infrastructure restoration in the aftermath of two separate storms on June 17 that impacted the Ameren Illinois service territory.

We appreciate our customers continued patience as restoration work continues to get all power restored.

Crews have restored 88,000 customer outages or roughly 93 percent of the outages. The remaining outage count stands at 6,600 customers, most concentrated in the communities of Galesburg, Monmouth, Decatur, Effingham, Mattoon and Charleston. More than 400 power poles were damaged during the two storms.

More than 1,700 in-house workers, support personnel, and contractor resources (vegetation management and lineworkers) will remain engaged until the remaining customers are restored. See the Ameren outage map for the latest: www.ameren.com/outagemap

COMMUNICATION

• Ameren Illinois activated its Incident Management Team (IMT) at 10:30 a.m. on June 17 to coordinate resources and support restoration operations. The IMT remains fully activated.
• Ameren reminds customers that certain electrical equipment on the outside of a home or business, like the weatherhead, is owned by the customer. If damaged during a storm, this will need to be repaired by a qualified electrician before we can restore power to your home.

SAFETY

• Safety is the first and foremost concern during any weather event. Stay clear of any downed power lines or poles, as well as brush, shrubs and downed trees that may hide them. Always assume a downed wire is live.
• Customers should report any downed power lines to Ameren Illinois via the app or customer service line (800-755-5000).
