When Wires Become Power: India’s Energy Diplomacy and the Battle for Asia’s Grid

India’s domestic experience offers credibility, but credibility alone will not secure regional leadership. Partners must see tangible benefits, including dependable electricity supplies, fair commercial terms and infrastructure that serves their own development priorities.

Oil once dictated the terms of power. In the emerging Asian order, transmission lines may have a say too. As countries rethink energy security amid shifting supply chains and the uncertain pace of the energy transition, the ability to move electricity across borders could become an important instrument of regional influence.

India’s support for the ASEAN Plan of Action for Energy Cooperation 2026–2030, expressed at the 20th East Asia Summit Energy Ministers’ Meeting in Manila, reflects this changing landscape. Representing India, Minister of State for Power Shripad Yesso Naik backed deeper regional cooperation, including the ASEAN Power Grid and a proposed 2,000 MW electricity interconnection between India and Singapore. If realised, the latter could open a new chapter in India’s energy engagement with Southeast Asia.

The proposal, however, remains under exploration. One option involves a transmission corridor of approximately 3,000 kilometres linking Imphal to Singapore through Myanmar, Thailand and Malaysia. Its geopolitical appeal is evident, but so are the obstacles. Building such a connection would require substantial investment, technical coordination and political commitment across several national jurisdictions. The real test of India’s energy diplomacy will be whether it can turn this ambitious proposition into a commercially viable and operational network.

The Power of Connectivity Begins Where Diplomacy Becomes Practical

India already has a useful precedent for understanding what cross-border electricity trade can achieve. On 15 November 2024, electricity generated in Nepal began reaching Bangladesh through Indian transmission infrastructure. The transaction involved 40 MW, a modest quantity in the context of India’s enormous power system, but its significance extended well beyond the volume of electricity exchanged. Three countries had translated a diplomatic agreement into a functioning commercial arrangement.

That experience offers a grounded reference point for the proposed India–Singapore connection. Regional energy integration does not begin with grand announcements or ambitious capacity targets. It advances when governments agree on transmission access, commercial terms and operating procedures, then build the infrastructure required to make electricity flow across borders.

The ASEAN Power Grid offers a broader framework for pursuing this ambition across Southeast Asia. Greater interconnection can help countries exchange electricity according to changing demand and supply conditions, improve the use of existing generation capacity and accommodate larger shares of solar and wind power. Countries with surplus electricity could potentially serve markets facing shortages, provided transmission capacity and commercial arrangements make such exchanges feasible.

For India, participation creates an opportunity to deepen its engagement with ASEAN through practical cooperation. Yet a power grid cannot run on goodwill. It needs engineering, money, rules and trust, particularly when electricity must cross several borders before reaching its destination.

A 3,000-Kilometre Link Faces the Hardest Test

The proposed 2,000 MW interconnection between India and Singapore captures the promise of regional electricity trade, but its geographical reach makes the project exceptionally demanding. A land-based corridor connecting Imphal with Singapore would pass through Myanmar, Thailand and Malaysia, requiring coordination among countries with different electricity markets, regulatory systems and infrastructure priorities.

The technical questions are substantial. Long-distance transmission requires decisions on suitable technology, network capacity, conversion systems where necessary and the management of power flows across interconnected grids. The participating countries would also need clear agreements on electricity pricing, transmission charges, access rights and responsibility for maintaining the infrastructure.

The commercial case deserves equal scrutiny. A 2,000 MW connection would need sufficient demand, dependable electricity supplies and a pricing structure capable of attracting investment over the project’s lifetime. Political instability or disruptions along the proposed route could further complicate construction and operations. Until these questions receive credible answers, the project should be treated as an exploratory opportunity rather than an imminent infrastructure breakthrough.

Nevertheless, the proposal deserves attention because it points towards a different understanding of energy security. Countries have traditionally sought protection through domestic production, diversified fuel imports and strategic reserves. Cross-border electricity networks add another dimension by allowing neighbouring economies to share available resources, although such interdependence also creates new vulnerabilities.

For India, the geopolitical opportunity lies in helping shape the rules and infrastructure of this emerging market. Its Act East Policy can gain greater economic substance when connectivity extends beyond roads, ports and trade agreements into the electricity systems that sustain modern industry.

Renewable Energy Needs a Grid That Can Keep Up

India’s regional ambitions draw support from its domestic expansion of electricity infrastructure and non-fossil generation capacity. According to figures presented by Naik, India’s installed power capacity reached 558.8 GW on 30 September 2026, including 308 GW from non-fossil sources. These sources accounted for approximately 55 per cent of total installed capacity.

India also reported reaching the milestone of 50 per cent of cumulative installed electricity capacity from non-fossil sources in June 2025, five years ahead of its 2030 Nationally Determined Contribution target under the Paris Agreement. The distinction between capacity and actual generation remains important, since installed capacity measures the rated output of power plants rather than the electricity they produce over a given period.

Still, the expansion provides a substantial foundation for cooperation with Southeast Asian partners. India has developed experience in deploying renewable energy at scale, expanding transmission networks and managing the changing requirements of its electricity system. Sharing this expertise could help regional partners assess solutions suited to their own energy needs.

The challenge is that renewable generation does not always match electricity demand. Solar output declines after sunset, while wind generation fluctuates with weather conditions. Stronger transmission networks, improved forecasting and battery storage can help manage these variations, but each requires careful planning and investment.

This is where regional interconnection becomes particularly relevant. A wider electricity network can provide additional options for balancing supply and demand across different markets, although its effectiveness depends on the generation mix, transmission capacity and operating rules of participating countries. Cross-border trade cannot eliminate the difficulties of renewable integration, but it can expand the options available to grid operators.

From Rooftop Solar to Green Hydrogen, Cooperation Must Reach the Ground

India’s energy transition is also unfolding at the household level. Under the PM Surya Ghar initiative, approximately 5.01 million rooftop solar installations had benefited 5.95 million households by 29 September 2026, according to figures shared at the meeting. The programme illustrates how electricity generation can move closer to consumers while complementing the expansion of large power plants and transmission infrastructure.

For households, rooftop solar offers the possibility of generating electricity where it is consumed, potentially reducing dependence on grid-supplied power. The benefits, however, depend on installation quality, financing, maintenance and effective integration with local electricity networks. Distributed generation also requires utilities to adapt their planning and operating practices as more consumers begin producing their own electricity.

The regional cooperation agenda extends beyond solar power. India has expressed readiness to share expertise in battery storage, renewable energy forecasting and green hydrogen, alongside knowledge exchange on carbon capture, utilisation and storage and carbon credit trading. Each area presents different opportunities and limitations, making practical assessment more useful than broad declarations of technological promise.

Green hydrogen, for instance, could help reduce emissions in industries where direct electrification remains difficult, although costs and infrastructure requirements continue to shape its commercial prospects. Battery storage can improve flexibility in electricity systems, while carbon management technologies may offer options for sectors that are harder to decarbonise. Regional exchanges could help countries evaluate these approaches without assuming that every technology will suit every market.

India has also identified tactical petroleum reserves, emergency preparedness, liquefied natural gas supply security and electricity system resilience as potential areas for cooperation. These priorities matter because energy transitions do not remove the need to manage immediate supply risks. Countries must maintain reliable energy supplies while gradually changing how they generate and consume power.

The Institutions Behind the Wires Will Determine the Outcome

Physical infrastructure receives much of the attention in regional energy discussions, but institutions and technical expertise determine whether interconnected systems can operate reliably. Naik called for stronger links between the ASEAN Centre for Energy and Indian organisations, including NTPC, POWERGRID, the Central Electricity Authority, the National Institute of Wind Energy and the National Institute of Solar Energy.

Such partnerships could support joint research, professional exchanges and training in transmission planning, grid management and renewable energy integration. India has also recalled Prime Minister Narendra Modi’s announcement at the 22nd ASEAN–India Summit in 2025 to support the ASEAN Power Grid by training 400 professionals in grid connectivity.

This emphasis on training reflects a practical requirement. Electricity systems cannot be connected securely through infrastructure alone. Engineers and grid operators must understand how interconnected networks behave, how power flows should be coordinated and how disruptions in one part of a system might affect another.

The institutional agenda also gives India an opportunity to build durable partnerships without waiting for the proposed Singapore connection to advance. Technical training, knowledge sharing and cooperation on emergency preparedness can produce practical gains even when large infrastructure projects face delays or financial constraints.

The broader framework is already in place through the ASEAN Plan of Action for Energy Cooperation 2026–2030 and the ASEAN–India Plan of Action for the same period. The task now is to identify projects with clear economic value, establish workable regulatory arrangements and ensure that cooperation continues beyond ministerial meetings.

India’s energy diplomacy therefore stands at an important juncture. The proposed 2,000 MW India–Singapore connection could eventually become a significant achievement, but its future depends on the difficult work of financing, negotiation and engineering. Meanwhile, the Nepal–Bangladesh electricity transaction demonstrates that smaller, carefully negotiated arrangements can already turn regional cooperation into measurable outcomes.

The larger question is whether Asia’s energy relationships will remain organised primarily around competition for fuel or gradually expand towards the shared use of electricity networks and clean energy resources. India has an opportunity to help shape that transition, provided it approaches connectivity as a long-term economic undertaking rather than a diplomatic spectacle. A transmission line may appear unremarkable against the skyline, yet the agreements governing its operation can reveal much about the future distribution of regional power.
