Overview
- A treaty-based international intergovernmental organisation focused on promoting solar energy deployment worldwide.
- Established to support clean energy transition, energy access, and climate change mitigation.
- Works through implementation, finance mobilisation, and capacity building, rather than negotiations.
Origin and Establishment
- Launched in 2015 by India and France during COP-21 (Paris Climate Conference).
- The Framework Agreement entered into force in 2017, giving ISA a legal international status.
- Recognised as the first international organisation headquartered in India.
- National Institute of Solar Energy (NISE), Gurugram, Haryana, India
Membership
- Membership open to UN member states with significant solar potential.
- Initially focused on countries located between the Tropic of Cancer and Tropic of Capricorn.
- Partner country status available for countries outside the tropical belt.
- More than 100 countries are signatories, with over 90 ratified members.
Objectives
- Scale up deployment of solar energy technologies globally.
- Reduce the cost of solar power through aggregation of demand.
- Mobilise finance, technology, innovation, and research for solar projects.
- Enhance energy access, particularly in Least Developed Countries (LDCs) and Small Island Developing States (SIDS).
- Support global efforts to combat climate change and improve energy security.
‘Towards 1000’ Strategy
- Mobilisation of USD 1000 billion in solar investments by 2030.
- Provision of clean energy access to 1000 million people.
- Installation of 1000 GW of solar energy capacity.
- Reduction of 1000 million tonnes of CO₂ emissions annually.
Institutional Structure
- ISA Assembly
- Apex decision-making body.
- Comprises representatives from all member countries.
- Approves policies, budget, and appoints the Director General.
- First Assembly held in 2018 at Greater Noida, India.
