Questions answered

How many substation and transformer fires have there been?

The register holds 866 substation and transformer entries from public reporting, 2005 to 2026, in 75 countries. 272 of them are fires or thermal events; the rest are electrical, other, mechanical and other incidents. Each entry lists its sources.

What causes substation and transformer fires?

Where the public reporting names a part, the most common are transformer (442), cable or overhead line (126), switchgear or breaker (49). 329 of the 866 entries name no part. The register does not guess a cause; where a fire service, regulator or the operator states one, the entry carries it and says who said it.

Where do substation and transformer incidents happen most?

In the reporting the register has found, United States (353), South Africa (122), United Kingdom (90) have the most entries. 90 are in the United Kingdom. That partly reflects where the assets are built and where the press reports on them.

What this page covers, and what it does not

Public reporting on substation and transformer incidents often names the site but rarely the make, the model or the cause. The register does not guess them. Where a fire service, regulator or the operator states one, the entry carries it and says who said it.
