That’s already setup: they export something like ¾ of the electricity they produce to India. I suspect this is either trying to get higher rates or possibly challenges related to their seasonal hydropower issues – if India is building more capacity for the times when the water levels are too low, the long-term rates aren’t going to be going up.
