What is the core cause for the lack of electricity?
From what I am reading in articles these days it looks like govt has put a cap on tariff increase by providers/producers like KESC and last year and this year we saw big jump in oil prices rendering KESC short of money as they had to buy expensive oil and less profit margin, high line losses, govt not paying its dues. Bottomline KESC wasn't able to recover its money so started to shut down its generators/units, stopped repairing transformers etc.
Govt has put a cap of 5% increase in tariff, KESC can't increase tariff by more than 5% regardless of how high the oil rises. So there should be some relaxation on that side, govt and private sector should setup a body which can come to a compromise on how much tariff increase is acceptable.
