Companies named in the reporting of this entry (being named is not a finding of fault): National Grid

On 20 May 2024, heavy smoke and flames were seen coming from the street in downtown Lowell, Massachusetts, in what was reported as an apparent transformer fire around 2:45 p.m. Aerial video showed large clouds of black smoke and heavy flames from what appeared to be a transformer or a dumpster in the area of Warren Street. Firefighters had just arrived. A spokesperson said National Grid was investigating the cause and had cut power to the transformer to make the scene safe for first responders. National Grid said about 120 customers were left without power. The cause and the exact equipment involved were not confirmed in the report.

Not reported. The source did not establish whether the fire started in a transformer or in nearby material.

  1. Treat street-level smoke and flame near electrical equipment as a possible grid incident until the operator confirms what is involved.
  2. Isolating the affected equipment before firefighters work close to it reduces electrical risk.
  3. Early reports may not distinguish a transformer fire from nearby burning material, so the asset and cause should be confirmed before they are stated as fact.
