GGI resource library

Compiled in this library are key research reports published by agencies such as the IEA and IRENA, along with analyses and studies produced by the GGI Ecosystem.

Projects and products

Principles for Interconnectors

The GGI Principles for Interconnectors document is an effort of the GGI to provide a set of guiding principles (best practices) for developing interconnectors across its lifecycle.

Electricity Transition Playbook

Produced by the Climate Compatible growth team, the Playbook serves as a practical guide to help countries navigate through the complex journey of the electricity transition. It features nine interconnected building blocks of electricity transition with resources for each and has a community of growing knowledge to share best practice.  

Insights from National Grid

An interview with National Grid - moving to a decarbonised energy system

GGI Ecosystem mapping

An analysis of global clean energy initiatives and their enabling conditions.

ZiZaBoNa and the importance of transmission investments in Africa

In this short presentation, GGI Africa Working Group Lead, Moeketsi Thobela, outlines key developments in transmission and power system integration across Africa, including progress with ZiZaBoNa.

Principles for the development of cross-jurisdictional grids

In this presentation, GGI's Policy & Engagement Lead, Rob Cooke, outlines the principles for interconnection that have been developed by a dedicated international task force. The principles will be launched at COP28 as a guide for governments.

Reports and research

IEA report: Electricity Grids and Secure Energy Transition

This report on the critical importance of grids for the energy transition is another clear reminder that there is #notransition withouttransmission.

IRENA report: Tripling renewable power and doubling energy efficiency by 2030: Crucial steps towards 1.5°C

This report concludes that a significant acceleration in the deployment of renewable energy, energy storage and renewable fuels, coupled with tangible progress in energy efficiency and electrification of end-use sectors, are required to put the world back on course to meet global climate goals.

The World Energy Outlook 2023 provides in-depth analysis and strategic insights into every aspect of the global energy system. This year’s report explores how structural shifts in economies and in energy use are shifting the way that the world meets rising demand for energy. 

Mobilising climate finance for grids investments

The analysis presented in this paper suggests that less than 40% of the grid investment needed in 2030 in EMDEs would be climate finance attributable under current eligibility criteria used by financing organisations.

Climate finance - taking stock of current approaches

Lack of climate finance for grid infrastructure in developing countries is constraining the supply of clean electricity to where it is needed most, jeopardising energy access and emission reduction goals.

The Breakthrough Agenda Report 2023

Accelerating sector transitions through stronger international collaboration


A free modelling tool that lets users identify least-cost pathways to decarbonize the global energy system. It is open-source, uses open-data, and is publicly accessible via http://osemosys. global/

Gulf-Undersea-India study

This study is an independent combined techno-economic and financial analysis of an electricity interconnector between Gulf Cooperation Council (GCC) countries and India.
