TNEI On Grid – The Connections Crunch
The industry has a problem. The connections queue currently contains more than double the generation capacity that is required in Great Britain. This poses the question, how are the networks handling the overabundance of generation developments and how will their solutions impact the future of GB’s pipeline of renewable energy? What is the Connections Queue? The connection queue comprises projects waiting connection to the network, with generators now being offered connection dates into the late 2030s and almost 2040. As of 5th November 2024, NESO published in their Great Britain’s Connections Reform -Overview Document’ that the connection queue currently consists of over 750 GW of capacity. TNEI estimate that the current transmission queue, in addition to the distribution queue (>1 MW), could supply close to twice the required installed capacity for the most ambitious 2024 FES scenario (Holistic Transition) as seen in Figure 1. The connection queue continues to grow
