What Happened
- The International Solar Alliance (ISA) celebrated its Foundation Day, with Union Minister of New and Renewable Energy Pralhad Joshi highlighting the alliance's growing global momentum
- The ISA has grown to 125 member and signatory countries, with 77 partner organisations and a growing network of young solar professionals trained at IIT Delhi
- ISA Director General Ashish Khanna noted that while the first 1,000 gigawatts of global solar capacity took nearly 25 years to install, the next 1,000 GW is expected to be achieved much faster — indicating accelerating global solar adoption
- The ISA announced the Green Hydrogen and Storage Start-up Challenge 2026 to support innovative startups in green hydrogen and energy storage
- The alliance launched an upgraded website to improve engagement with member countries and partners
- ISA programmes have contributed to solarising health centres, enabling solar irrigation, and supporting renewable energy startups in member countries

International Solar Alliance: Origin, Structure, and Mandate
The International Solar Alliance (ISA) was jointly proposed by Indian Prime Minister Narendra Modi and French President François Hollande at the 21st Conference of Parties (COP21) in Paris on November 30, 2015. Initially conceived as an alliance of "sunshine countries" — nations lying between the Tropics of Cancer and Capricorn (23.5°N and 23.5°S) — the ISA was subsequently opened to all UN member states in 2020. The ISA's headquarters is at the National Solar Energy Institute in Gurugram (Gurgaon), Haryana, India. Its framework agreement entered into force on December 6, 2017.
- Proposed at: COP21 Paris, November 30, 2015
- Co-founders: India (PM Modi) and France (President Hollande)
- Headquarters: National Solar Energy Institute, Gurugram, India
- Framework Agreement entered into force: December 6, 2017
- Original mandate: Nations between Tropics of Cancer and Capricorn (77 countries)
- Amended mandate (2020): All 193 UN member states eligible
- Current membership: 125 member and signatory countries
- ISA DG: Ashish Khanna (as of 2026)
- Host country: India; co-host: France
Connection to this news: Foundation Day celebrations reflect ISA's evolution from a narrow tropical-nations grouping to a genuinely global solar institution — cementing India's role as a leader in multilateral clean energy governance.
India's Renewable Energy Targets and Solar Mission
India's solar energy ambitions are anchored in its National Solar Mission (NSM), launched in 2010 as part of the National Action Plan on Climate Change (NAPCC). The NSM's target has been progressively revised upward: from 20 GW (2022 target, 2010) to 100 GW (2022 target, 2015) to 500 GW of non-fossil fuel capacity by 2030 (India's NDC commitment to UNFCCC). India crossed 100 GW of installed solar capacity in 2024, becoming one of the world's top solar markets. India has committed at COP26 (Glasgow, 2021) and COP27 (Sharm el-Sheikh, 2022) to ambitious clean energy transitions under its "Panchamrit" targets.
- National Solar Mission: Launched January 11, 2010
- India's solar installed capacity (2024): crossed 100 GW
- India's 2030 renewable target: 500 GW non-fossil fuel capacity
- India's Panchamrit targets (COP26, 2021): Net zero by 2070; 50% power from non-fossil by 2030
- Production Linked Incentive (PLI) scheme for solar modules: Launched to reduce import dependence
- PM Surya Ghar Muft Bijli Yojana (2024): Rooftop solar for 10 million households
Connection to this news: India's domestic solar push provides both the credibility and the market scale that underpins its ISA leadership — demonstrating to smaller developing nations that solar transition is achievable.
Climate Finance and the North-South Divide in Energy Transition
A recurring challenge in global clean energy diplomacy is the financing gap for developing nations transitioning away from fossil fuels. At COP29 (Baku, 2024), developed nations committed to a "New Collective Quantified Goal" (NCQG) of $300 billion per year by 2035 for climate finance — a figure that developing nations, including India, argued was insufficient. ISA plays a role in addressing this gap by mobilising concessional financing, technical assistance, and capacity building specifically for solar projects in developing nations.
- NCQG (COP29, 2024): $300 billion/year by 2035 from developed to developing countries
- India's demand: At least $1 trillion/year in climate finance from developed nations
- Green Climate Fund (GCF): UN body for climate finance; India has received significant project approvals
- ISA's One Sun One World One Grid initiative: Proposed global solar grid to share solar power across time zones
- ISA Towards 1000 initiative: Aims for 1,000 GW of new solar capacity and $1 trillion in investments by 2030
Connection to this news: ISA's Green Hydrogen and Storage Start-up Challenge 2026 directly addresses the energy storage bottleneck that has held back solar adoption in developing nations — showing ISA's evolution from awareness-building to practical problem-solving.
