Although reliable data is not readily available, the hydraulic potential of the region is huge.
Consequently the discussion about the size of this remaining potential is largely academic, not to say a waste of time, since it is clearly evident that it would take more than a decade to implement all feasible sites with today’s available implementation capacities.
Furthermore there are market niches which have not been discussed in the past. It is remarkable that even the tiny, oil rich state of Brunei has a hydro potential which would deserve to be harnessed and it would be a highly desirable political sign if a state with abundant fossil fuel resources would start to invest into renewable energy options.
