Electricity grids across the globe must double their capacity, with approximately 80 million kilometers of power lines requiring replacement or addition by 2040, according to a groundbreaking report by the International Energy Agency (IEA). The report, titled 'Electricity Grids and Secure Energy Transitions', reveals that the current pace of grid growth, which is approximately one million kilometers annually, is insufficient to meet climate and energy goals.

The delay in connecting renewable projects to the grid is a global issue, exacerbated by factors such as the COVID-19 pandemic and geopolitical events like Russia's invasion of Ukraine. This has caused delays in procuring essential components like 50 MVA power transformers, with typical lead times extending from 11 to 18 months.

Additionally, the demand for grain-oriented electrical steel (GOES), a crucial component of transformers and electric vehicle charging stations, is increasing while supply, particularly from Russia, has decreased due to sanctions.

The age of existing grid systems is another concern, with insulation materials degrading and circuit breakers becoming less reliable. The report highlights that some electrical assets in advanced economies are over 50 years old.

Efforts to address these challenges require stronger international collaboration, and a failure to expand and improve grid infrastructure could result in a significant rise in CO2 emissions, undermining global efforts to combat climate change.
