Your question makes a lot more sense with your explanation. As Jonathan has said IR scans are used to identify hot spots which includes loose connections but I don't imagine anyone has carried out a cost benefit analysis as the immediate action is to fix the loose connections. I would endorse this action as the loose connection could be a potential fire risk and the cost benefit of fixing it compared to having a fire needs little analysis. I also suspect that the load shedding you mention is as much, of not more, down to overloading of the supply circuits rather than an effect of poor connections. However since IR scans will also give indications of overloaded circuits and other local hot spots there may be benefit in the study you suggest.
