About Customer Connections
Welcome to the home of customer connections at SSEN Transmission.
Making sure that generation, storage and demand development can connect to our network is one of our primary responsibilities as the owner of the electricity transmission network in the north of Scotland. We have a vital job to do over the coming years to make sure that our network is capable of connecting planned additional generation capacity.
Following Ofgem’s approval of NESO’s Connections Reform proposals, we have been working with NESO and our customers to deliver the new connections process, which supports the delivery of Government’s Clean Power 2030 (CP30) Plan. The first step in this is the delivery of revised connection offers for projects that have been successful in their application for Gate 2 and have demonstrated to NESO the necessary evidence. This exercise will be carried out in conjunction with NESO over the coming months, and we will engage with customers through this process as we progress in revising connection offers. More details on this engagement will be shared directly with customers through our Customer Relationship Team.

We received our list of Gate 2 projects/reformed connections queue from NESO in early December. This marked the beginning of our role as a TO in delivering the Gate 2 to the Whole Queue (G2tWQ) process, when we undertake our power system studies and prepare revised connection offers for successful projects.
NESO notified customers about the outcome of their applications December 2025 NESO expects to issue revised connection offers to Phase 1 protected projects (connecting in 2026/27).Remaining Phase 1 projects (connecting 2027-2030) should receive their revised offers no later than the end of June 2026, and Phase 2 projects (connecting 2031-2035) should receive their revised offers by the end of September 2026.
The opening date for the first application window of the new, enduring process will be shared by NESO. In the meantime, NESO has published its revised timeline for the next stages of Connections Reform, providing customers with key project milestones for the next year.
