Examine India's role as a regional power-trading hub in South Asia, with reference to its electricity agreements with Nepal and Bhutan.

India sits at the infrastructural centre of South Asia's electricity map — importing hydropower from Bhutan, trading both ways with Nepal, and wheeling Nepali power to Bangladesh through its own grid [2]. This makes it the region's de facto power-trading hub, though the role remains institutionally uneven.

Physical and institutional foundations

• The 400 kV Dhalkebar–Muzaffarpur corridor, sanctioned to evacuate Arun-3 power, remains the backbone of India–Nepal exchange [1].
• A POWERGRID–Nepal Electricity Authority MoU creates joint venture companies for the 400 kV Inaruwa–New Purnea and Dododhara–Bareilly double-circuit links [3].
• India's cross-border trade rules let neighbours access Indian trading platforms and exchanges, converting bilateral wires into a market [4].

Nepal: two-way, seasonally complementary trade

• Nepal's run-of-river fleet yields monsoon surplus and winter deficit, so India both buys and sells within a single year [4].
• India is investor-cum-offtaker: Arun-3 (900 MW, SJVN), export-oriented, with electromechanical works underway [3].
• After the August 2026 flash floods damaged Nepali generation, Kathmandu sought imports advanced to September 2026; India signalled willingness to supply additional power [5] — hub status doubling as disaster diplomacy.

Bhutan: the mature model

• The 2006 Hydropower Agreement and 2009 Protocol committed India to develop 10,000 MW in Bhutan for export to India [6].
• Punatsangchhu-I (1200 MW) and II (1020 MW) anchor this; India exports back during Bhutan's lean season [7].

Limits to the hub claim

• Imports run on capped quotas, conditional and seasonal approvals, and hour-restricted windows — adequate for routine trade, brittle in emergencies.
• Climate-induced Himalayan flood and GLOF risk threatens the very hydro assets the model rests on [5].
• Trade stays bilateral and India-mediated, not a unified regional market.

India has convincingly built the grid, capital and regulatory plumbing of a South Asian power hub. Consolidating it now requires firm multi-year import assurances, climate-proofed transmission, and a rules-based regional market extending the Nepal–India–Bangladesh trilateral precedent — advancing energy security, SDG-7 and Neighbourhood First together.
