The Eighth Session of the International Solar Alliance (ISA) Assembly will be held from Oct. 27 to 30, 2025, at Bharat Mandapam, New Delhi. This high-level ministerial gathering comes weeks ahead of COP30 in Brazil, shaping priorities for scaling solar energy, unlocking transformative finance, charting technology and policy roadmaps, and building skill ecosystems to accelerate a just and inclusive energy transition.

At the curtain raiser for the Eighth ISA Assembly, Union Minister of New and Renewable Energy, Pralhad Joshi, invited global partners to join the Assembly for shaping a solar-powered world.

“Owing to its clear vision and consistent policies, India achieved its renewable energy targets five years ahead of the schedule, crossing the 50% mark in overall installed electricity capacity from non-fossil resources. Today, with approximately 125 GW of solar capacity, India is the world’s third largest solar power producer,” said the minister.

“We have seen first-hand how decentralised solar transforms lives, brings light to rural homes, powers local health centres and gives new tools to our farmers. With PM Surya Ghar – Muft Bijli Yojana, more than 20 lakh households are benefiting from solar power.”

The minister added, “Under the PM-KUSUM scheme, we are taking this transformation to the heartland of India. The three components of the scheme target the installation of 10 GW of small solar plants; support 1.4 million off-grid solar pumps; and solarise 3.5 million grid-connected agricultural pumps. Together, these efforts are ensuring that clean energy reaches the last mile.”

Santosh Kumar Sarangi, Secretary, India’s Ministry of New and Renewable Energy, emphasized ISA’s role in experience sharing, in cross learning and in deploying solar both at scale as well as at a distributed level. “We remain committed to continue this collaboration in future and in a variety of ways through both financial support as well as technical support which we have been extending to ISA.  We also wish to see how it can be scaled up in other countries. Some of the deployment experiments in Africa have shown encouraging results,” said Sarangi. “Given India’s success in deploying solar energy at both utility and distributed levels—through household and farm-level initiatives such as the PM Surya Ghar – Muft Bijli Yojana, which aims to solarise 10 million households, and the PM-KUSUM scheme for farm-level solarisation—India is ready to partner with other countries in implementing similar initiatives.”

The International Solar Alliance is a global initiative launched in 2015 by India and France at COP21 in Paris. It has 124 Member and Signatory Countries. The Alliance works with governments to improve energy access and security worldwide and promotes solar power as a sustainable transition to a clean energy future. ISA’s mission is to unlock investments in solar while reducing the cost of the technology and its financing. It promotes the use of solar energy in agriculture, health, transport, and power generation sectors.

Ashish Khanna, Director General of ISA, emphasised ISA’s role in enhancing solar deployment through aggregation, harmonising technology standards, enabling data-driven energy planning, supporting research and innovation, and advancing One Sun, One World, One Grid (OSOWOG). He highlighted India’s potential to become the “Silicon Valley for Solar” with the establishment of the Global Capability Centre (GCC), linked with STAR-C hubs worldwide for technical support, digital tools, and training.

The Eighth Session of the ISA Assembly will focus on four strategic pillars: Catalytic finance hub; global capability centre & digitisation; regional & country-level engagement; and technology roadmap & policy. Ministerial and technical sessions will explore actionable priorities, including advancing catalytic finance through the Africa Solar Facility, and strengthening country partnerships through the Small Island Developing States (SIDS) Platform—a dedicated initiative to support SIDS in accelerating solar energy deployment through finance, technology, and capacity-building partnerships.

The Assembly will also see the release of ISA’s flagship reports—Ease of Doing Solar 2025 and Solar Trends 2025.
