Ameren Missouri Storm Restoration Update as of 12 p.m. July 4

12 p.m.
Tuesday, July 4


Hundreds of additional personnel from a neighboring state are in Missouri today to help restore power to Ameren Missouri customers.

Weather update: There is a medium threat for severe weather on Wednesday, July 5, throughout Ameren Missouri’s entire service territory. We anticipate the majority of customers from the weekend storm systems will be restored by the end of the day Wednesday, assuming continued safe working conditions and that weather conditions do not delay our progress. 


Today, on the July 4 holiday, we have a total of 1,300 people engaged in restoration -- including line workers, vegetation management, damage assessors, drone teams and safety representatives.. This includes additional mutual aid crews from Illinois.


We’ve safely restored power to approximately 94,000 Missouri customers to date.  

  • It will take some time to accomplish repairs for remaining customers.
  • We will work to safely restore power to customers as soon as possible, 
  • We anticipate restoration efforts will extend until Wednesday evening given the damage caused by several waves of powerful weather events.
  • As we continue damage assessment, we are finding additional destruction of utility infrastructure after brush and debris are cleared. This has delayed restoration for some customers.
  • As of 11 a.m. on Tuesday, around 27,000 customers are without power. See the Ameren outage map for the latest: www.ameren.com/outagemap


We estimate a total of more than 160 poles have been replaced or still require replacement.  


Our crews are addressing significant tree and infrastructure damage caused by strong winds.  

  • In difficult conditions such as downed tree limbs and challenging terrain, it takes at least four to five hours, sometimes longer, to clear a damaged utility pole and set a replacement.  


We also are seeing damage to transformers and substations.


Drone teams have been deployed to help pinpoint damage quickly and safely so our line crews can focus on restoration efforts.   


When prioritizing restoration work, Ameren Missouri works to restore power to equipment that serves the greatest number of customers and to critical facilities. Some of the restoration jobs involving critical facilities have required additional specialized equipment be brought to the scene, which has slowed some repairs in some cases.

We understand that our customers are frustrated, and we ask for patience as our crews work to restore power. We also advise customers to 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.

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.



  • Highly destructive severe weather cut through the Midwest over a multi-day period last weekend, causing significant and widespread additional outages throughout Missouri.
  • The entire Ameren Missouri service territory has been affected by the weather, with the St. Louis metropolitan area getting hit the hardest.
  • We're continuously monitoring weather conditions for additional weather threats this week. As of Tuesday morning, there is a medium threat for severe weather on Wednesday, July 5, throughout Ameren Missouri’s entire service territory.



  • 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.
