India and UK launch green grids initiative to deliver clean power to the world

Prime Minister Narendra Modi and UK Prime Minister Boris Johnson launched a new flagship international initiative to dramatically accelerate the global transition to a clean powered world.

Indian Prime Minister Narendra Modi and UK Prime Minister Boris Johnson jointly launched a new flagship international initiative today (2 November 2021), at the COP26 World Leaders Summit, backed by over 80 countries, to dramatically accelerate the global transition to a clean powered world.

Jointly led by the India and UK , the new initiative, called “Green Grids Initiative – One Sun One World One Grid” (GGI-OSOWOG), will accelerate the development and deployment of interconnected electricity grids across continents, countries and communities, and improve energy access of the poorest through mini-grids and off-grid solutions.

It features as one of the leading initiatives under the Glasgow Breakthroughs also launched at the clean innovation and technology event, part of a new joint plan that will see countries and businesses coordinate and strengthen their climate actions every year in polluting sectors to dramatically scale and speed up the deployment of clean technologies and drive down costs globally.

In launching the initiative, the two Prime Ministers unveiled the ‘One Sun Declaration’ setting out a shared vision of harnessing the full potential of clean power globally through much greater interconnection of electricity grids across continents, countries and communities, including mini-grids and off-grid solutions to ensure no one is left without access to energy.

To meet the goals of the Paris Agreement and limit global warming to within 1.5C, the world will need to transition to clean power, increasing the global reliance on renewable energy, like solar and wind power. Transitioning to this clean powered future will require developing an electricity infrastructure that is capable of coping with far greater shares of variable renewable energy, while meeting growing power demands securely, reliably and affordably.

The GGI-OSOWOG will help make this happen, by bringing together a global coalition of energy grid stakeholders, including governments and businesses, to accelerate the expansion of energy grids across regions and continents and create the foundations for universal access to sustainable energy. This will ensure the infrastructure is in place for the whole world to be powered by renewable energy, as part of the global push to realise the clean energy transition. 

Keeping 1.5C alive means global emissions will need to be cut in half by 2030. Achieving this will require a dramatic acceleration in innovation and deployment of clean energy solutions, and on a global scale. The International Energy Agency’s recent analysis calls for a tripling in investment in grid expansion and modernisation from $260bn to $800bn annually by 2030.

The initiative will help to mobilise financial and technical resources to advance grid developments, and also promote the sharing of existing expertise and best practice across the globe. This international collaboration will be key to making the clean energy transition faster, cheaper and easier for all.

Prime Minister of India, Mr Narendra Modi said :

The One Sun One World One Grid and Green Grids Initiative is an idea whose time has come. If the world has to move to a clean and green future, these interconnected transnational grids are going to be critical solutions. I congratulate the International Solar Alliance and the UK COP Presidency for bringing it nearer to implementation.

UK Prime Minister Boris Johnson said at the launch:

The UK is working hand in hand with our friends in India to transform the future of the power sector and ensure clean and reliable electricity is accessible everywhere by the end of this decade. It’s fantastic that over 80 countries have backed our newly launched Green Grids Initiative, whose collaboration will not only see greater growth, jobs and investment in our global green future, but also make sure no one is left without access to energy.

The GGI-OSOWOG is a transformational new programme, with the goal of making universal access to renewable energy a reality, by ensuring that clean power is the most affordable and reliable option for all countries to meet their energy needs efficiently by 2030. This will help all of us to meet the goals of the Paris Agreement and keep the target of limiting global temperature rise to 1.5 degrees alive, while also stimulating green investment and supporting millions of jobs worldwide.

Green Grids Initiative - One Sun One World One Grid

One Sun Declaration

Glasgow, 2 November 2021

The untapped potential of the sun is well known - all the energy humanity uses in a year is equal to the energy that reaches the earth from the sun in a single hour. The sun never sets – every hour, half the planet is bathed in sunshine. By trading energy from sun, wind and water across borders, we can deliver more than enough clean energy to meet the needs of everyone on earth. This trading is already beginning to happen through discrete bilateral and regional arrangements. But to meet the sheer scale of the challenge, these efforts need to be brought together and supplemented to create a more inter-connected global grid. We call this vision: One Sun One World One Grid. We need new transmission lines crossing frontiers and connecting different time zones, creating a global ecosystem of interconnected renewables that are shared for mutual benefit and global sustainability. This must be combined with expanded and modernised national and regional grids and complemented with the rapid scale-up of mini-grids and off-grid solar solutions. To help deliver the vision of One Sun One World One Grid, we have resolved to combine our efforts and create a more inter-connected global grid. Our next step is to develop an action agenda for global cooperation on this agenda. Through working groups of interested governments, regulators, financiers, institutions, companies, legislators and researchers, we will seek to provide a common global framework for efforts on:

1. Investing in solar, wind, storage and other renewable energy generation in locations endowed with renewable resources for supporting a global grid.

2. Building long-distance cross-border transmission lines to connect renewable energy generators and demand centres across continents, underpinned by effective and mutually beneficial cross-border power trading arrangements.

3. Developing and deploying cutting edge techniques and technologies to modernise power systems and support green grids which can integrate billions of rooftop solar panels, wind turbines and storage systems.

4. Supporting the global transition to zero emission vehicles through incorporating the role of electric vehicles to help improve grid flexibility.

5. Attracting investment into solar mini-grids and off-grid systems to help vulnerable communities gain access to clean, affordable, and reliable energy without grid-access in their own areas, enhancing socio-economic development and a resilient power supply for all.

6. Developing innovative financial instruments, market structures, and facilitate financial and technical assistance to attract low-cost capital, including climate finance, for global solar grid infrastructure. Through these and other efforts, we intend to cooperate internationally to share ideas and learn from each other’s successes and expertise. In this common endeavour, we can ensure that the sun becomes a secure and reliable source of energy for all, especially for the world’s underprivileged citizens.

Realizing One Sun One World One Grid through interconnected green grids can be transformational, enabling all of us to meet the targets of the Paris Agreement to prevent dangerous climate change, to accelerate the clean energy transition, and to achieve the Sustainable Development Goals. These efforts can stimulate green investments and create millions of good jobs. By sharing the sun’s energy, we can help to build a more peaceful and prosperous world.
