What happened

A malfunction at the Lakeview Avenue electric substation in Mayville, New York, operated by the Village of Mayville, led to a series of loud bangs, flames and small transformer failures, causing a brief fire. A feeder line failed, cutting power to part of Mayville for about ninety minutes before crews redirected supply from a second substation to restore service. Officials later declared a state of emergency to expedite repairs at the damaged substation.

As part of the repair works, a four hour villagewide power outage was scheduled so crews could assess the extent of the damage and establish a repair timeline, with officials aiming to complete repairs before the onset of winter.

Contributing factors

Mini-transformers failed and one feeder blew out at the Lakeview Avenue substation, according to the mayor, who described the cause in general terms rather than as a confirmed technical root cause.

Lessons learned

  1. A second interconnected substation allowed supply to be rerouted and restored in ninety minutes after the feeder failure.
  2. Mini-transformers and feeders at distribution substations need targeted inspection when general failure descriptions are given.
  3. Declaring a state of emergency can speed repairs at a damaged substation ahead of winter.
