I would be very surprised if the next nuclear plant does not have much larger capacity like the example I gave - BD power demand by then would be like twice what it is now.
Any country that relies on volatile/unreliable and potentially expensive fossil fuelled power plants is going to ruin itself.
This will also accelerate BD investments in hydroelectric power plants in Nepal/Bhutan. 500MW will come in 2026 from a joint venture between Nepal/BD and Bhutan and more will follow soon after I am sure.
This year and part of 2023 will be tough for sure but things will slowly get better from 2nd half of next year for BD.
I am not sure how wise the Nepal/Bhutan investment is, it creates a dependency on Indian goodwill. The political weather between nations don't remain same all the time, it is best not to create dependency on critical matters such a power.
