SSE's transmission business has accepted a new five-year funding settlement from energy regulator Ofgem, securing a major programme of investment for grid upgrades across the north of Scotland
The agreement forms part of Ofgem’s RIIO-T3 price control — the framework that sets how much revenue electricity transmission operators can collect between April 2026 and March 2031, and what infrastructure and performance targets they must deliver in return.
Following a detailed review of the Final Determination, SSEN Transmission said it recognises the outcome as an “investable and deliverable settlement overall”.
The company said: “The RIIO-T3 price control comes at a critical time for securing clean, affordable and reliable power for families and businesses across the country. The investment it delivers will help reduce reliance on imported energy from overseas, remove grid bottlenecks and strengthen energy security. It will also act as a major catalyst for economic growth, jobs and supply chain investments across the UK to unlock the country's full clean energy potential.”
SSEN Transmission’s investment programme includes 11 major transmission reinforcements designed to expand capacity and connect renewable generation. The company has already secured 75% of major planning consents, with six schemes fully consented and five in construction. Securing the remaining approvals will be a key focus for the rest of the year.
It added: “SSEN Transmission continues to work constructively with Ofgem, Government and wider stakeholders as it delivers the investments in new and upgraded infrastructure that are required to help deliver clean power, energy security and lower bills for current and future generations.”
