Power supply to the 66 kV PAU substation and 66 kV Fountain Chowk substation of Punjab State Power Corporation Limited (PSPCL) remained disrupted for nearly 13 hours on Wednesday due to damage caused to a main power cable between the 220 kV Firozepur Road substation, which feeds the two 66 kV substations. Power supply that was shut at around 2.30 pm on Wednesday could be restored only after 3 am on Thursday.
