One Sun One World One Grid (OSOWOG) Programme on Regional and Global Interconnections is a flagship initiative of the ISA designed to foster the cross-border transmission and trade of clean and affordable electricity. This initiative aims to develop a network of interconnected grids across regions and continents, enabling the sharing of surplus renewable power and strengthening energy security among participating countries.
Overview
The One Sun One World One Grid (OSOWOG) Programme on Regional and Global Interconnections is a flagship initiative of the International Solar Alliance (ISA) designed to foster the large scale cross-border transmission and trade of clean and affordable electricity across regions and continents, advancing the realization of the visionary OSOWOG concept announced by the Hon’ble Prime Minister of India, Shri Narendra Modi.
Objectives
The Programme seeks to create and strengthen global and regional electricity transmission networks and support the development of the OSOWOG Super Grid a transformative global energy infrastructure and integrated electricity markets across regions and continents, enabling the continuous flow of renewable energy, reducing dependence on fossil fuels, and enhancing energy security, affordability, and sustainability worldwide.
Outcomes
One Sun One World One Grid (OSOWOG) Programme on Regional and Global Interconnections will pave the way for a global renewable energy grid and electricity markets that links multiple regions across Far East to Far West with India at the fulcrum, time zones, facilitating greater solar power and renewable energy utilisation and shared access to clean energy.
This programme directly aligns with ISA’s mission to promote universal access to clean, affordable and sustainable energy. By connecting solar and renewable energy-rich regions with high-demand zones, it embodies the spirit of One Sun One World One Grid, a transformative vision in which solar energy transcends borders to power a greener, more resilient and prosperous world for all.
