India is rapidly emerging as a regional hub for clean energy and is positioning itself to shape the future of international green-power cooperation through the One Sun One World One Grid (OSOWOG) initiative. Hosting the headquarters of the International Solar Alliance (ISA) in New Delhi further reinforces India’s leadership. While OSOWOG often evokes images of long undersea cables connecting continents, the practical foundations of this vision are taking shape much closer to home. Over the past decade, India has developed a strong network of cross-border electricity links with Bhutan, Nepal, Bangladesh and to a smaller extent, Myanmar. Some of these corridors are mature, while others are expanding steadily, but together they form the real building blocks of the OSOWOG vision.
