Very good points mS.
The number for Pak will be even lower if account for the population increase since it was last estimated to be 160 m.
Another important point is that many estimates for Pakistan’s electricity fail to see the difference between:
1 - Installed capacity
2 - Average output accounting for seasonal variations in the flow of water etc.
3- Pakistan’s electricity plants on Tarbela and Mangla are primarily for water supply and not for electricity generation. Thus in the months we need to store water, there is very little electricity coming out of those two BIIIIIG plants.
Bottom line is that we have to generate 30,000 MW to 100,000 MW more power to have industrial output and public lifestyle of developed countries.
