About OSOWOG Initiative

The idea for the One Sun One World One Grid (OSOWOG) initiative was put forth by the Hon’ble Prime Minister of India Shri Narendra Modi, at the First Assembly of the ISA in October 2018. The initiative aims at connecting energy supply across borders.

Vision Behind the Initiative

The vision behind the OSOWOG initiative is the mantra that “the sun never sets”. The OSOWOG initiative aims to connect different regional grids through a common grid that will be used to transfer renewable energy power and, thus, realize the potential of renewable energy sources, especially solar energy.

Launch of GGI-OSOWOG Initiative & One Sun Declaration

The GGI-OSOWOG initiative was jointly launched by Hon’ble Prime Minister of India, Shri Narendra Modi and the, then, Hon’ble Prime Minister of United Kingdom, the Rt Hon. Boris Johnson, during the ‘Accelerating Innovation and Clean Technology Deployment’ event at the World Leaders Summit held on 2 November 2021 during COP26.

In addition to the launch of the initiative, this event also included the launch of the ‘One Sun Declaration’ as approved by the Fourth Assembly of the ISA. The “One Sun Declaration” can be accessed here.
