What happened

A fire broke out in the switchyard at Guddu Thermal Power Station and caused six electricity-generating units to trip. The interruption affected supplies in parts of Sindh, Balochistan and Punjab. Fire crews brought the blaze under control, after which plant personnel worked to restore supply through alternate arrangements. The reviewed source did not report casualties, identify a specific generating unit as the seat of the fire or quantify the lost capacity. An account supplied for this dataset described a separate late-night event around 1 October as a Unit 6 fire that removed 600 MW and was the plant's fourth fire within a month; those date, unit, capacity and recurrence details could not be independently established from an accessible source, so they are not presented here as confirmed facts.

When cited sources give different casualty, damage or spill figures for this event, they’re reported side by side above rather than merged into one number. See how confidence levels work.
