11,300 Lose Power When Backup Equipment Fails In Wentzville


WENTZVILLE, MO (KTVI) – An Ameren spokesperson says 11,300 customers in Wentzville, Missouri, lost power around 8:00am Tuesday.  Scheduled maintenance took power off a main line, but the backup equipment failed at a sub station, causing the outage.

About half the customers regained power within 15 minutes, and the other half were restored by 8:35am.

Wentzville police Captain Kevin Pyatt says the department activated its reverse 911 call system to tell residents about warming centers. 

Pyatt says officers went door-to-door to check on elderly residents.

Ameren officials say they do not know why a nearby substation broke down. They are investigating why the backup equipment failed.

Wentzville police say they will keep those warming centers ready in case the city loses electricity again.
