The International Solar Alliance became a treaty-based organisation after its framework agreement was ratified by 19 countries.
This also marked the first time India being the base of a treaty-based international government organisation.
ISA—an alliance of 121 sunshine countries situated between the Tropics of Cancer and Capricorn– was formulated with India having a lead role.
The ISA aims at large scale deployment of solar energy through better harmonization and aggregation of demand from the sunshine countries.
India, France, Australia, Bangladesh, Comoros, Cuba, Fiji, Guinea, Ghana, Malawi, Mali, Mauritius, Nauru, Niger, Peru, Seychelles, Somalia, South Sudan, and Tuvalu have so far ratified the treaty, which is signed by 46 countries.
