This 4000 MW of AC load simply vanished from the system demand after the mercury dropped by 7-8C on late September 5. The system remained so till September 08 where-after it has slowly built up at a rate of 800-900 MW a day. Energy labelling is unheard of and Pakistan remains a dumping ground for gas guzzling and inefficient electrical equipment. The present requirement of cooling is being managed by double the required load viz. only 2000 MW. As such, besides being unduly loaded by a non-productive AC load of 4000 MW, the power system has also to arrange for expensive peaking generation without much returns. Pakistan cannot afford such extravagant usage of ACs and that all such usages have to necessarily result in great increase in utility revenues. We must use ACs most frugally, and these have to be energy labelled with only efficient models allowed to be imported and manufactured locally.
