UPDATE – Ameren Missouri Storm Update – July 23, 2017

Ameren Missouri crews have made great progress restoring power to customers following last night’s storms. As of 4:00 p.m. today, fewer than 20,000 customers were still without power.


At the peak, more than 50,000 customers were without service, with the largest concentration of outages in the St. Charles and north St. Louis County areas.


The latest outage information is available at https://outagemap.ameren.com/. You can track outages by county and/or by zip code on our Ameren Outage Map website.


We thank all of our customers for their patience while power is being restored.
