Ofgem has today (1 July 2025) released its Draft Determination on our RIIO-T3 Business Plan, in which we set out how we will transform our transmission network in central and southern Scotland from 2026 to 2031.
Commenting on the release of the Draft Determination,
Nicola Connelly, CEO of SP Energy Networks, said: “Our plans to invest up to £12bn into the major rewiring of Britain will unlock capacity and economic growth, as well as reducing electricity bills and network constraints. This is exactly what is needed to electrify the country, support households and businesses, and deliver the Government’s Clean Power 2030 ambitions.
“In today’s Draft Determination, we welcome that Ofgem recognises this historic investment is critical to ensuring energy security. We will now take time to analyse their initial position in more detail. Between now and December we will engage to ensure a balanced regulatory framework that incentivises this critical investment is delivered.”
The Draft Determination from Ofgem follows an extensive review and consultation period on our business plan that was published in December 2024.
An Ofgem consultation on the Draft Determinations is open until 26 August 2025. Final Determinations (including publication of consultation responses) is expected in Winter 2025.
