What I have learned is that, in April 2008, Pakistan was producing 50 percent more electricity than today. Reason is that many thermal plants are not working today plus shortage of water in dams was also restricting electricity generation, that may easy after recent rains and increasing water inflow to dams. I think that if Pakistan can make all plants work then Pakistan would overcome most of electricity shortages.
Where did you learn that?
What was demand last year (vs production)? Years before? Howcome we never came out of load-shedding in past 20-30 years? (please don't resort to finger pointing, thanks).
If Pakistan have to come out of electricity shortages, than they have to start building hydro-power plants (in other word ... dams ... big and small), nuclear power plants, solar power plants, wind-power plants, wave power plants, etc ... and come out of thermal power plants.
How many possible (and feasible) locations are there to build dams?
Unfortunately, thermal power plants are easy to build, and has potential of giving good commission to politicians, so politicians might go for it.
Due to nuclear sanction I don't think Pakistan can go for reactor-generated elctricity.
