I also don't agree with the idea of producing electricity in Nepal or Bhutan, electricity power plants are strategic and there should never be a dependancy on other countries for it even if it's only 5%. I never agreed with Hasina's policy of getting Indian or Nepalese/Bhutanese electricity. If we can produce 95% of our needs in BD, it's not too hard to do 100%, this was simply not needed.
Hydroelectric in Nepal and Bhutan was a bad idea, it was not required. Hasina is a good policy maker but nobody is infallible, I don't agree with what she did with this one.
Ok, let us agree to disagree on the other points you made as we are too far away for there to be anything close to a meeting of minds.
What exactly would be wrong with BD getting up to 20% of its power from Nepal/Bhutan via India, as it would always keep this amount of fossil fuel powered stations on standy anyway and so in the worse case scenario of this power stopping there would be little effect on BD?
The chances are pretty much zero anyway as India would need to be in a seriously bad place to even think about stopping transmission of electricity where it financially benefits anyway, not to mention it would seriously anger Nepal and Bhutan who would come to rely on the billions of dollars every year they would get from BD.
Hydroelectric power is clean and cheap. For BD to build the equivalent nuclear would require an extra decade and taking out 10s of billions in extra loans. BD may have the money but it does not have the time here. GWs of cheap and clean hydroelectric power will probably flow from Nepal and potentially Bhutan by 2030.
There is no real negatives to this if you really thing about it and that is why Hasina is going through with it.
