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

Shortly before midnight on Wednesday 10 July 2024, a transformer at a substation at a chemical facility in Institute, Kanawha County, West Virginia, exploded. A viewer near the Altivia Plant recorded video of the sky lighting up from the blast. The Institute Fire Department responded to the scene. According to fire crews, the transformer blew up and there was no chemical exposure or threat to the public. Dispatchers reported no injuries. AEP, the utility, said there were no extended power outages as a result of the incident, and dispatchers said any impact on power was localised to the facility. Altivia was contacted for comment; no response is reported.

The cause of the transformer failure was not reported in the source.

  1. Transformer failures at substations on industrial or chemical sites can release considerable energy, so fire response plans and exclusion zones should cover the substation as well as the process plant.
  2. Confirm early with fire crews and dispatch whether any chemical exposure exists, so that residents receive accurate information quickly.
  3. Isolate and protect transformers with adequate separation and fault detection so that a single unit failure stays localised and does not interrupt supply to surrounding communities.
