The International Energy Agency (IEA) is warning that investment in transmission and distribution infrastructure is failing to keep pace with renewables projects, and is leading to a large and growing queue of projects waiting to be connected to the grid globally. In a newly published report titled ‘Electricity Grids and Secure Energy Transitions’, the agency notes that advanced projects with a combined capacity of 1 500 GW, or five times the amount of solar and wind capacity added worldwide in 2022, are currently waiting to be connected to the grid.
