Ameren Missouri Storm Restoration Update as of 9 a.m. July 16


  • Over the last 36 hours, crews have restored service to approximately 41,000 customers in Missouri.
  • Our resources and repair efforts continue to be focused in north St. Louis County, which was the hardest hit area of the storms on Friday night and into Saturday. This area also saw a pop-up thunderstorm around 7 p.m. Saturday night, leading to minor damage and about 150 additional outages.
  • We will continue working to safely restore power to customers as soon as possible, but as we continue to assess damage, we anticipate restoration efforts will extend through the day today and possibly into Monday. In an event with widespread outages, individual estimated restoration times are not immediately available.
  • Visit the Ameren outage map for the latest information: Ameren.com/outagemap.
  • More than 950 crew members are engaged in restoration. This includes more than 600 line workers and 350 vegetation management personnel. Mutual assistance crews from other states are assisting with restoration efforts.
  • Our vegetation management crews are in the field cutting and removing large trees and branches, which can take considerable time before additional crews can complete repairs.

  • High winds and severe thunderstorms popped up in various locations of our service territory on Friday night and early Saturday morning, affecting our customers throughout the metropolitan St. Louis area. More than 80% of the damage was located in St. Louis County, with a heavy concentration in North St. Louis County.
  • Widespread damage from two lines of severe thunderstorms included large tree limbs and downed trees that have fallen on poles and wires. The damage has affected distributed lines and higher voltage sub-transmission lines.



  • The energy grid is highly interconnected. Repairs may be happening several blocks, or miles away. Customers may not ever see Ameren Missouri vehicles on their street during restoration efforts. 
  • Today's forecast does not include any additional severe weather, but summer pop-up storms are always possible in the Midwest. Ameren Missouri is closely monitoring weather reports across our service territory this weekend for additional storms and weather threats.
  • Drone teams were deployed to help pinpoint damage quickly and safely so our line crews could focus on restoration efforts. These crews collected information so that line crews are equipped with what they need for local repairs when assigned.



  • Priority one is to respond to life-threatening emergencies, such as downed-wires, and to handle all problems impacting critical infrastructure such as hospitals and other emergency response facilities – police and fire, and municipal systems.
  • Once power is restored to critical infrastructure, we focus on getting the most customers restored in the quickest and most efficient manner. Crews begin with main lines – those that can restore power to perhaps thousands of people – and then move to lines that affect individual homes and neighborhoods.
  • Because of their general location along primary power lines, homes in the same neighborhood may be restored at different times. It's also why businesses are sometimes restored first.



  • Safety is the first and foremost concern during any weather event. Stay clear of any downed power lines or poles. Always assume a downed wire is live. Be careful around pools of water. Stay clear of brush, shrubs and downed trees that may hide downed power lines. 
  • Customers should report any downed power lines to the Ameren Missouri customer line: 800.552.7583.  
  • If your power is out, check your circuit breakers or fuses – your service outage might be the result of a household problem. Avoid any risk of electrical shock and do not enter any flooded areas.   
  • Create a plan for seeking shelter in the event of severe weather and discuss the plan with all members of the household.
  • Keep phones and electronics charged when storms are in the forecast.
  • Prepare a storm kit with emergency telephone numbers, flashlights and a radio with fresh batteries, along with bottled water and non-perishable foods that don't require heating. Also include medication and special items for infants, the elderly or family members with special needs.
  • Ameren Missouri is encouraging customers to check on friends and neighbors and individuals with special needs.
