India to the World: From a Solar Decade to the Next Terawatt
Over the past decade, India has undergone one of the most rapid renewable energy transformations in the world. Solar capacity has grown from approximately 9 GW in 2016 to more than 168 GW today, establishing India as one of the world’s largest and fastest-growing solar markets.
During New York Climate Week, ORF America, the Natural Resources Defense Council (NRDC), and the International Solar Alliance (ISA) convened India to the World: From a Solar Decade to the Next Terawatt, bringing together policymakers, industry leaders, investors, and energy experts to examine what enabled India’s solar expansion, what the next phase of the transition will require, and what lessons India’s experience can offer the wider world.
The discussion reflected a broader shift in the energy transition. Renewable energy is increasingly linked not only to climate goals, but also to energy security, economic growth, industrial development, and resilience. The challenge now is moving from rapid deployment to building the systems, institutions, and investment conditions needed to sustain that scale.
Participants also explored how India’s experience could inform renewable-energy deployment elsewhere, particularly in countries seeking to expand affordable and reliable power while reducing exposure to imported fuels.
Key takeaways included:
India’s challenge is shifting from adding renewable capacity to integrating it into a more complex electricity system. India’s rapid solar expansion has made it the world’s third-largest solar market and one of the largest markets for annual installations. The next phase will depend increasingly on grid modernization, transmission, distribution, storage, and system flexibility so that growing volumes of renewable power can be absorbed and delivered reliably.
India’s solar decade demonstrates the importance of combining long-term ambition with institutions that make projects investable. Rising national targets, a unified electricity grid, and transmission-charge waivers created strong market signals, while the Solar Energy Corporation of India (SECI) helped aggregate demand, run competitive auctions, and provide credible counterparties. India’s experience shows that ambitious targets work best when institutions can translate them into predictable and financeable markets.
For the next terawatt, policy certainty and bankable pipelines may matter as much as the availability of capital itself. Participants emphasized that capital can move quickly where regulation is stable, counterparties are credible, returns are transparent, and project pipelines are sufficiently large. The harder constraints often arise earlier — around land, permitting, transmission, project preparation, and institutional capacity — making de-risking, blended finance, and stronger domestic institutions critical.
Distributed renewable energy can extend the economic benefits of the solar transition beyond utility-scale generation. Rooftop and distributed systems can support jobs, rural livelihoods, small businesses, agriculture, and greater local energy resilience. India’s experience also highlights the need for flexible policy design, including community and shared-solar models where conventional rooftop deployment is difficult.
Energy security increasingly depends on resilient clean-technology supply chains as well as access to fuel. While renewables reduce dependence on imported fossil fuels, key parts of the solar supply chain remain highly concentrated. Diversification therefore requires deeper capabilities across minerals, processing, cells, batteries, equipment, testing, R&D, and emerging technologies, not simply expanding module assembly.
The next phase of renewable deployment must be planned alongside the new forms of electricity demand it will enable. Electrification of transport, industry, and digital infrastructure will reshape both the scale and profile of electricity demand. If designed well, electric mobility and other flexible loads can support — not only strain — the power system, making it increasingly important to plan generation, storage, grids, and electrification as one integrated system.
India can increasingly serve as an implementation partner for the wider world. Its experience in competitive procurement, market aggregation, grid development, energy access, digital systems, distributed energy, and institutional design provides approaches that can be adapted to different national contexts. Platforms such as the International Solar Alliance can help translate these domestic lessons into practical international cooperation, technical expertise, supply-chain diversification, and institutional partnerships.
One clear message from the discussion was that the next terawatt of solar will be about much more than adding generation capacity. It will depend on whether countries can build the grids, storage, manufacturing capacity, effective institutions, financing models and strong partnerships needed to turn cheaper solar technology into reliable and affordable power.
