India Bets on Cross-Border Power Trade to Firm Its Renewables Grid

India Bets on Cross-Border Power Trade to Firm Its Renewables Grid Former power secretary Alok Kumar argues regional electricity trade beats batteries on cost, as intermittent renewables strain India's grid and Asian fuel markets stay volatile. Former Indian power secretary Alok Kumar told Outlook Business on Wednesday (2026-06-03) that regional power trade is the cheaper way to manage India's grid as renewables come to dominate new capacity.⁷ That matters because intermittency is now the binding constraint on India's power system, not raw capacity. Renewable energy leads new additions, but solar and wind output swings put pressure on grid managers who must keep supply and demand matched second by second. Kumar frames the choice plainly: battery storage is one fix, cross-border electricity trade with neighbours is arguably the smarter and cheaper one.⁷ The argument rests on geography and timing. Power demand peaks at different hours across South Asia, and a connected grid lets a surplus in one country cover a shortfall in another without anyone building and paying for idle storage. Bangladesh, Nepal and Bhutan already sit inside India's regional trading orbit. The pitch is that interconnection substitutes for capital-intensive batteries at the margin.⁷ The same logic is driving thinking elsewhere in Asia. Mott MacDonald, the consultancy, argued in mid-May (2026-05-19) that ASEAN's surging electricity demand, pushed higher by data centres and digitalisation, needs gigawatt-scale renewables paired with a connected regional grid and subsea interconnectors. Its caveat is the relevant one for India too: these projects stall on regulatory gaps, financing hurdles and supply-chain bottlenecks.⁴ Those frictions are why interconnection remains a slower answer than its economics suggest. Cross-border power lines need aligned market rules, settlement mechanisms and political trust across borders that do not always cooperate. A line drawn on a map is cheap. The institutional plumbing behind it is not, and it is where most regional trade ambitions slow down.^4,7 The case for firming India's grid has sharpened because the fuel alternatives look expensive and unreliable. Asia's top LNG importers turned back to coal through mid-May (2026-05-19) as the conflict involving Iran disrupted Middle East energy routes and squeezed global LNG supply. Spot LNG prices roughly doubled, and Asian LNG imports fell sharply in what was described as the biggest drop on record.⁵ The supply shock has a clear origin. Qatar's main LNG export facility, which normally handles about 17% of global flows, went offline after an Iranian drone strike, according to reporting from mid-May (2026-05-19). Asian spot LNG prices pushed above $25 per mmBtu as damage to Qatari infrastructure and disruption around the Strait of Hormuz cut supply forecasts. For an importer like India, that is the worst kind of price signal to build a grid strategy around.^6,3 India is not insulated from the oil side either. The Mangalore MRPL refinery, which accounts for 6% of India's crude-processing capacity, shut one of its three units and was reported to have declared force majeure on some exports, a claim it denies. Across the region, refiners are cutting runs by 10% or more, Kpler estimated in mid-May (2026-05-19). When imported fuel turns this volatile, domestic generation that does not depend on it becomes more valuable.³ Coal remains the fallback, and that is the uncomfortable part. Coal still supplies roughly 35% of global electricity despite the renewables build-out, with over 2,000 GW of capacity operational worldwide as of 2024, according to industry statistics published in mid-May (2026-05-20). Every gigawatt of firm, low-carbon supply that regional trade can substitute is a gigawatt that does not have to come from a coal plant kept running for reliability.¹ There is a contrary read worth holding. Signals on German baseload front-month pointed bearish in mid-May, driven by supply, a reminder that interconnected markets can transmit price weakness as readily as firming benefits. Cross-border trade exposes a grid to its neighbours' surpluses and their problems alike. [contrarian] India's wider tilt toward partners is visible in trade too. Europe and India have moved on a long-delayed free-trade deal, though the energy read is modest: EU exports to India run about €76bn, just 0.4% of EU GDP, the Economist noted in mid-May (2026-05-19). The deal signals alignment more than it reshapes energy flows.² The thing to watch is whether any of this converts into firm interconnection capacity or stays a policy aspiration. Kumar's economics are sound on paper. The test is whether South Asian governments can build the market architecture before the next fuel shock forces them back to coal. Until then, regional trade remains the cheaper option that is hardest to actually build.^7,5
