Ameren and Southwestern operations and engineering teams are on site this afternoon, working to isolate the source of an outage affecting the cooperative's Pocahontas Substation. About 1,100 members served by the sub have been without power since 10:55 a.m., when an Ameren transmission line that energizes the substation failed. As of 2 p.m., no estimated time of restoration was available.
Shortly before 1:45 p.m., Southwestern Electric Cooperative’s St. Jacob Substation lost power, leaving about 800 Madison County members without service. The substation was energized at about 2 p.m. The cooperative’s operations and engineering teams believe an Ameren transmission line issue was responsible for the outage.
Members who see downed or sagging power lines should stay clear of the area and contact Southwestern Electric Cooperative at (800) 637-8667. In addition, people clearing debris should look for sagging or fallen wires before they begin working and treat every powerline as if it’s energized.
