International Solar Alliance 2025

The International Solar Alliance 2025 marks a historic milestone in India’s leadership in solar energy and renewable energy. The Eighth ISA Assembly, held on October 28, 2025, in New Delhi, brought together 125 member nations to strengthen global cooperation for a clean energy future.

This major event showcased India’s commitment to promoting solar power, building a green economy, and accelerating sustainable development through solar innovation.

Background of the International Solar Alliance 2025

The International Solar Alliance (ISA) was launched by India and France in 2015 to encourage global collaboration in solar energy and to reduce dependence on fossil fuels. Over time, the alliance has evolved into a significant platform for promoting solar panels, solar grid development, and innovative financing for renewable energy projects.

By 2025, under the International Solar Alliance 2025, the organisation had reached 125 member countries, symbolising a strong global commitment toward clean energy, climate action, and sustainable development.

The event emphasised the need for an inclusive energy transition supported by innovation, research, and global solar connectivity.

Key Initiatives Launched at the International Solar Alliance 2025

The International Solar Alliance 2025 witnessed the launch of several transformative initiatives aimed at advancing solar power adoption worldwide.

SUNRISE: Turning Solar Waste into Wealth

One of the most significant announcements at the International Solar Alliance 2025 was the SUNRISE initiative, which focuses on solar waste management through upcycling and recycling. It promotes a circular solar economy, encouraging the transformation of discarded solar panels into valuable materials.

This initiative not only supports sustainable development but also generates solar jobs and training programmes, turning waste into opportunity. The SUNRISE solar upcycling initiative is a step toward India’s vision for a circular and green economy.

OSOWOG: One Sun, One World, One Grid

The One Sun One World One Grid (OSOWOG) initiative is another key highlight of the International Solar Alliance 2025. This ambitious project aims to establish a global solar grid connecting continents such as Asia, the Middle East, Europe, and Africa.

Benefits of global solar grid connectivity (OSOWOG):

• Promotes cross-border renewable energy trade

• Reduces energy costs and carbon dependency

• Enhances energy security and resilience against climate change

• Demonstrates how OSOWOG connects Asia, Europe, and Africa seamlessly

This initiative reflects how India leads the International Solar Alliance 2025 by promoting solar innovation and fostering global solar connectivity.

Global Capability Centre (GCC) and ISA Academy

Under the International Solar Alliance 2025, the Global Capability Centre (GCC) acts as a central hub for solar research and innovation. It supports AI-driven learning, advanced technology incubation, and collaboration among solar startups.

The ISA Academy complements this by providing AI-driven training and solar skills development through online and in-person courses. Together, these initiatives aim to make India a global leader in solar R&D, fulfilling the vision of a Silicon Valley for Solar.

These programmes also represent India’s vision for a circular solar economy, building human capacity for renewable energy advancement worldwide.

SIDS Procurement Platform: Solar for the Vulnerable

The SIDS Procurement Platform, introduced during the International Solar Alliance 2025, was co-developed with the World Bank to support Small Island Developing States (SIDS). This platform enables joint procurement of solar power technologies, reducing costs and ensuring energy security for climate-vulnerable island nations.

It provides sustainable solutions for solar waste recycling, resilience building, and solar innovation in regions most affected by climate change.
