Making sure that generation developments can connect to our network is one of our primary responsibilities as the owner of the network in the north of Scotland and we have a huge job to do over the coming years to make sure that our network is capable of connecting the planned additional generation capacity. For this reason, we have a major programme of investment underway which involves upgrading and reinforcing the network and fundamentally changing its historic role.

In January 2025, the National Energy System Operator introduced a temporary pause in connection applications. This pause aims to deliver a stable foundation for implementing its new connections process , subject to Ofgem approval. It will allow customers time to have a signed offer in place when the implementation stage of the process begins. Consequently, new connection applications are not being accepted at present. Visit NESO’s Transition to Connections Reform for further information, and learn more about the pause in applications in NESO’s FAQ document.
