Without a consistent and coherent regional regulatory framework in place, investment opportunities and, consequently, large-scale CBET between nations that could benefit both importing and exporting nations may not happen. In the South Asian regional context, the risks associated with forging an intra-regional, CBET project would be greatly minimized if each participating country adopts complementary regulatory frameworks to facilitate cross-border interconnection and electricity trade. The SAARC Inter-Governmental Framework Agreement (IGFA) also calls for the need for institutional mechanisms for the coordination of regulations for promoting CBET in the South Asia (SA) region.This paper brings out the above by analyzing the international experiences in power market development and CBET from a) Greater Mekong Region (GMS) b) South African Power Pool (SAPP) c) West African Power Pool (WAPP) d) The Central American Electrical Interconnection System (SIEPAC) e) Nordic Pool and the critical success factors for effective CBET and learnings for South Asian countries from international experiences. The report also highlights the various key drivers of CBET in SA and the current policy, legal, and regulatory frameworks in the region. I hope this paper will be able to initiate further thought-provoking discussions among regulators and power sector stakeholders to take forward the process of coordination of policy and regulation for promoting CBET.
