A big fire followed the catastrophic failure of a transformer last night at the Duquesne Light facility on Brunot Island.
Black smoke rising into the air could be seen for miles.
Fire crews were called to the island around 8 p.m. Pittsburgh Public Safety said the blaze and "any related hazards are contained to Brunot Island."
In a statement, Duquesne Light said there were no injuries or power outages.
Pittsburgh Public Safety says they worked with Duquesne Light crews on the land side in Marshall-Shadeland to devise a plan to learn as much as they could about the fire.
They accessed the island by barge to get equipment over to extinguish the fire.
Norfolk Southern has a rail line that crosses over the island. That was shut down for a short time and has since reopened.
"Duquesne Light and the Pittsburgh Bureau of Fire will continue to investigate the cause and monitor any further impact," Pittsburgh Public Safety said in a statement.
