A transformer failure at the Perche Creek substation knocked out power to more than 2,600 Columbia Water & Light customers on Monday evening, sending traffic into gridlock at a dark West Broadway and Fairview Road intersection during the height of rush hour.
Outage Map Showed Thousands Dark Across Southwest Columbia
At its peak, the Columbia Water and Light outage map showed 2,634 electric customers without power across southwest Columbia, according to ABC17News. Multiple outages were reported along Fairview Avenue, and a neighborhood west of Scott Boulevard alone accounted for more than 900 customers without service, the outlet reported. By later in the evening, the same outage map showed the number had dropped to about 300 customers still waiting for power to return.
Columbia Water and Light wrote on social media that the problem originated with a transformer at the Perche Creek substation, per the station's report. Crews worked through the evening to restore power to affected customers across the city, though the utility did not provide a specific timeline for full restoration in the information relayed to ABC17News.
Traffic Backed Up at Dark Intersection
The outage also disrupted traffic lights at West Broadway and Fairview Road, causing a long line of cars to back up during evening rush hour, the same report noted. Under Missouri traffic guidance, drivers approaching an intersection with completely unpowered signals must treat it as a four-way stop, coming to a complete stop and yielding to vehicles that arrive first or to the right, according to the Missouri Department of Revenue. Left-turning drivers must also yield to oncoming through traffic under that same rule, a detail that likely compounded the congestion at an intersection where thousands of commuters pass daily.
Same Corridor Hit By Storm Outage Weeks Earlier
Monday's outage struck the same general corridor that lost power less than a month earlier, when a severe storm knocked out electricity to more than 1,500 Columbia Water & Light customers, with the primary cluster centered along N. Fairview Road, as Hoodline previously reported. That August 6 storm affected 1,535 municipal utility customers alongside 537 rural Boone Electric Cooperative members outside city limits. The recurrence of outages in the same southwest Columbia footprint underscores long-running questions about the Perche Creek substation's reliability.
Perche Creek Powers More Than Homes
The stakes extend beyond home air conditioning and lighting. Columbia's McBaine Water Treatment Plant and the Gillespie Bridge Sewer Treatment Plant both draw their primary electrical power from the Perche Creek substation, according to COMO Magazine. Infrastructure advocates have noted that delays in fully connecting Perche Creek to a redundant feed left those critical water and wastewater facilities without a fully backed-up power source.
Columbia Water & Light serves roughly 50,000 municipal electric customers citywide, according to the American Public Power Association. That means Monday's peak outage figure represented roughly 5% of the utility's entire customer base losing power at once.
Grid Strain Meets a Decade-Old Political Fight
The outage lands against a backdrop of rising demand and long-delayed infrastructure fixes. Columbia's municipal electric grid hit a record peak load of 289 megawatts during peak summer weather this year, surpassing the previous 2011 record of 277 megawatts, according to COMO Magazine. Former utility officials have warned that running substations near or above firm capacity raises the risk of component failure during summer peaks like the one Columbia is experiencing now.
Columbia voters actually authorized fixes for this more than a decade ago. In April 2015, nearly 69% of voters approved Proposition 1, a $64 million municipal bond package for electric grid enhancements, but $32 million earmarked for a southwest transmission line sat unspent after the City Council paused the project in 2016 amid resident concerns over property impacts, visible poles, and electromagnetic fields, per COMO Magazine. In February 2026, the City Council approved an option involving a new 161-kilovolt transmission line through Vawter School Road, according to the City of Columbia. Public-input meetings were held on August 11, with a related presentation on August 20, 2026.
Underground Upgrades Already Planned for the Area
Columbia is also pursuing infrastructure improvements near Perche Creek, as previously reported by 93.9 The Eagle. Columbia's Climate Action and Adaptation Plan includes a goal of a 100% renewable-electricity standard by 2030.
