A review of energy sector in the BBIN sub-region.

Although the BBIN (Bangladesh-Bhutan-India-Nepal) sub-region shares identical socio-economic characteristics and secures considerable benefits from energy co-operation and power grid connectivity, it is still far behind to grasp its full potential. This paper reviews existing publications and papers from a viewpoint of resource distribution, energy supply, prospects, and policies related to power sector development and cross-border power trading with a detailed consideration of the spatial variation of the largest country, India. The member countries face similar energy problems and the challenge remains in overcoming growing energy demand by attaining emission reduction targets. Limited production but increasing use of imported fuel have also raised serious environmental and energy security concerns. The wide variation in the energy resource endowments among the countries, particularly with hydropower, coal, and natural gas presents both opportunity and challenge in sub-regional energy collaboration.
