One hundred and thirty nations in one room, and a single agenda: make the sun the world's most reliable power source. Union Minister for New and Renewable Energy Pralhad Joshi presided over the inaugural session of the Ninth Assembly of the International Solar Alliance (ISA) on Tuesday, 3 November 2026, calling for stronger global cooperation, greater investment, and faster implementation to anchor clean energy as a driver of both energy security and shared prosperity.

A platform built in Paris, tested in practice

The International Solar Alliance was not born in a boardroom — it was announced by India and France at COP21 in Paris in 2015, with a founding vision of uniting sun-rich nations around a common solar agenda. The ISA Framework Agreement entered into force in December 2017, and the organisation has since grown into a treaty-based multilateral body headquartered in Gurugram, India. That India hosts the secretariat and chairs this assembly is no accident: New Delhi has consistently used the ISA as its most direct instrument of multilateral clean-energy diplomacy.

Each successive assembly has pushed harder on the same pressure points — concessional finance, technology transfer, and bankable project pipelines — particularly for member countries across Africa and Asia where solar potential is vast but capital remains scarce.

What Joshi put on the table

Addressing representatives from all 130 member countries, Joshi outlined a clear three-point thrust: deepen international cooperation, mobilise greater investment, and sharpen implementation so that solar transitions actually happen on the ground rather than in pledging documents. His remarks, delivered in English with identical messaging echoed in Kannada and Hindi in the post, framed clean energy not merely as a climate imperative but as an instrument of 'ಶಕ್ತಿ ಭದ್ರತೆ' (energy security) and 'वैश्विक समृद्धि' (global prosperity) — language that speaks directly to developing nations wary of energy poverty.

The session carries the hashtag #BharatRESummit2026, signalling that the assembly is nested within a broader renewable-energy summit India is hosting, reinforcing New Delhi's intent to shape the global clean-energy calendar.

India's 500 GW ambition and the ISA connection

The assembly's timing matters. India has staked its climate credibility on hitting 500 GW of non-fossil power capacity by 2030, with solar as the centrepiece. Every ISA commitment that actually moves finance or technology to a member country strengthens the argument that multilateral platforms can deliver — and that India can lead them. The G20 and successive COP meetings have given India a louder voice on clean-energy transitions; the ISA is where that voice is converted into institutional architecture.

The focus areas flagged by Joshi — investment mobilisation and swift implementation — are precisely the gaps that critics of multilateral climate bodies most often cite. Naming them at the inaugural session sets the tone for what the assembly will be judged on when it concludes.

The world's solar map is being redrawn assembly by assembly — and India is holding the pen.
