[Geo News] The hustle and bustle of life has been adversely hit by the breakdown occurred in many grid stations besides breakage of many high tension electric wires here in Karachi, leaving the metropolis covered with darkness on Tuesday, Geo news reported. People, having been suffered too much, have been sick of continuous power failures meanwhile, KESC has been carrying out load shedding for two to three hours after every alternative hour while cable faults have also added oil to the fire. According to KESC sources, the WAPDA is providing the required electricity to it but owing to flaws in KESC's own power generation units due to technical faults, it is unable to meet the metropolis electricity needs. KESC is entirely dependent upon electricity being produced by WAPDA and Gas, which has failed so far to end electricity crisis here in Karachi, KESC sources added.
