Outage concentrated on Chatham’s north side

Thousands of customers in Chatham lost electricity Monday evening after a distribution issue on the local grid. Utility provider Entegrus reported that the outage was concentrated on the north side of Chatham and, at its height, affected 3,719 customers before service was restored shortly after 8:30 p.m.

According to the utility, the interruption was traced to equipment on the distribution network. Crews were dispatched, identified the fault and completed repairs the same night, bringing customers back online in phases until full restoration.

In a Facebook update, Entegrus said the outage was caused by “a failed electrical connection on the distribution system.”

Cause identified and repairs completed

Entegrus attributed the service loss to a single-point failure within the distribution system, not to transmission supply or planned maintenance. While the utility did not specify the exact location of the failed component, it confirmed field teams addressed the problem and verified stability before re-energizing affected circuits.

Short-duration outages of this kind typically affect traffic signals, retail operations, and household routines in the impacted area. Residents on the north side of the city experienced the brunt of the interruption until crews completed repairs and confirmed the grid segment could be safely brought back into service.

What residents should know

While power has been restored, distribution faults can prompt brief follow-up interruptions as utilities monitor equipment after repairs. Customers who continue to experience localized issues—such as partial power, repeated breaker trips, or unusual equipment noise—should contact their utility and avoid attempting repairs themselves.

  • Report lingering outages or electrical concerns to the utility’s customer service line.
  • Treat any downed or low-hanging lines as energized and keep a safe distance.
  • Reset clocks, routers, and other devices; check refrigerators and freezers after extended outages.

Next steps

Entegrus indicated the immediate fault was repaired and service restored the same evening. The utility’s public note did not reference longer-term infrastructure changes, but after incidents of this nature, utilities commonly review the affected feeder and components to reduce the chance of similar failures. No further updates had been posted as of late Monday.

InfoRadar will continue to monitor for any additional information from Entegrus regarding follow-up inspections or advisories for customers on the north side of Chatham.
