Contractor reported struck by 12,000-volt explosion at AES Ohio substation in Ohio

EIR-0880

Provisional entry. Confirmed: a contractor was reported struck by roughly 12,000 volts in an explosion at an AES Ohio substation, reported November 2024. Not yet known: the substation location, the date, the work being done, the injury outcome and the cause. Next update: 18 September 2026.

A contractor was reported to have been hit by around 12,000 volts of electricity during an explosion at a substation operated by AES Ohio in Ohio, United States, according to a local news report published in November 2024. Only the headline and a short summary are available. The report available to the register does not give the substation location, the date of the incident, the nature of the work being carried out, whether the equipment was energised, the severity of the contractor's injuries, the emergency response, or any investigation findings. No information is available on whether the substation suffered damage or outage.

Not reported. No cause has been published in the available source.

  1. Work on or near energised high-voltage substation equipment carries an arc flash and explosion risk, so isolation, lockout and proof of dead procedures need to be verified before work begins.
  2. Contractors should be issued arc-rated protective equipment matched to the incident energy of the equipment they approach.
  3. Contractor briefing and permit control should confirm that visiting crews understand which parts of a substation remain live.
