Electricity Grids: The New Challenge of the Energy Transition

Global efforts to combat climate change and ensure reliable electricity supplies are at risk of being compromised if policymakers and companies do not act swiftly to improve and expand electricity grids. A report by the International Energy Agency (IEA) highlights the urgency of this situation.

Current Challenges of Electricity Grids

Electricity grids, essential for powering homes, factories, and infrastructure, are increasingly strained by the rapid growth of clean energy technologies like solar, wind, electric vehicles, and heat pumps. Without adequate investments and policies, current infrastructures will not keep pace, endangering the goal of limiting global warming to 1.5°C.

Infrastructure Needs by 2040

To meet climate and energy goals, an additional 80 million kilometers of power lines will need to be added or replaced by 2040, equivalent to the current global network. This will require doubling annual investments to over $600 billion per year by 2030.

Congestion of Renewable Projects

Currently, many renewable energy projects are stalled awaiting grid connection, representing a capacity of 1,500 gigawatts. This delay significantly hampers the energy transition.

Impact of Investment Delays

A scenario in the report shows that insufficient investments and slow reforms could result in an additional 60 billion tons of CO2 emissions between 2030 and 2050. This would undermine the Paris Agreement goals and increase the risk of exceeding a 2°C rise in global temperature.

Necessary Strategic Actions

To overcome these challenges, the report recommends expanding and strengthening grid interconnections within and between countries and promoting digitalization to improve grid resilience and flexibility. It is crucial that governments support large-scale transmission projects.


There is an urgent need to modernize and expand global electricity grids to meet climate goals and ensure reliable energy security. Policymakers and companies must work together to ensure infrastructures are prepared to meet the challenges of the energy transition. Investing in grids today is essential to avoid future bottlenecks and achieve a successful energy transition.
