KARACHI - The management of Karachi Electric Supply Company (KESC) has adopted a strategy of carrying out preventive measures in advance against the decades old policy based on the fault corrective maintenance. As a result, the latest spell of rains had witnessed a stable generating and grid system as compared to the past, while the distribution infrastructure had also improved considerably. This was stated by Zahir H Rizvi, director distribution, and Ayesha Eirabie, director corporate communications, at a media briefing. They said that in the past not much emphasis was put on upgrading the distribution system as required, for a long time. Therefore, there was still big room present for improvement. Previously the faults had been repaired after they occurred. However, now management had started preventing the faults in advance, but the total conversion of the entire network needs more time to complete. On the other hand, they said, because of little or no response towards complaints in the past, the consumers had developed a habit of not reporting their individual outages to the utility. This had prolonged the duration of their localised issues during the recent rains while they silently waited for the power supply to resume on itself but the utility could not take action without knowing about it. Therefore, the consumers needed to regain their trust over the response system of the KESC and always report an interruption the moment it took place, they added. They informed the media that the process of following preventive maintenance had been progressing quite effectively. In fact, instead of the past ratio of 1:4 of preventive and corrective maintenance, the present management had been following a policy of 3:3 ratio. This was visible from the smaller number of localised and individual faults during the recent rains as compared to the past. They pointed out that once a feeder had tripped or a cable broken because of the rains, the maintenance staff had to wait till the downpour stopped. Similarly, non-registration of complaint could indefinitely delay the correction. They appreciated the positive media role during the recent rains, and said there was a need to make the consumers understand how the system worked. Giving out operational update, they said that on Wednesday the KESC had been supplying 2,139MWs of electricity against an equal demand, with no loadshedding. Wapda had been supplying 610MWs. The total of 9 feeders had been under tripping, which were expected to be normalised before evening. Work was in progress on repair of 70 main cable faults out of the 93 registered during the previous 24 hours, while the remaining 23 faults had already been corrected. Important among the affected areas included Malir Villas area, two poles in Gadap, one PMT in Lines Area, one locality of PECHS and another in Bahadurabad. They further said that in Akhtar Colony, some residents had blocked installation of pole mounted transformer and that had resulted in delay of resumption of power. However, after the public reaction over the outages, it changed their mind and had allowed the utility to fix the problem, they added.
