Eight major electricity transmission projects in Scotland are set to progress following the announcement of early construction funding approval by energy regulator Ofgem.

This early financial commitment will enable essential civil engineering and infrastructure works to commence without delay.

The approved funding requests are for eight Scottish Hydro Electric Transmission Plc (SHET) projects, which are part of the Accelerated Strategic Transmission Investment (ASTI) framework. This streamlined process, launched by Ofgem in late 2022, is designed to help meet the UK Government's ambitious target of connecting between 43 and 50 gigawatts (GW) of offshore wind capacity by 2030.

The funds will be deployed for the early procurement of high-demand materials globally, such as High-Voltage Direct Current (HVDC) cables, and to finance associated enabling works like land purchases and surveys. The mechanism allows Transmission Operators (TOs) to secure materials early, mitigating the risk of costly procurement delays caused by fierce global competition for these resources.

Beatrice Filkin, Ofgem Director of Major Projects, stated: "Today's decision means that we'll be able to power more homes with homegrown clean power faster. Releasing early investment to suitable projects equips British Transmission Operators to compete globally, avoid delays caused by supply chain constraints and secure the sought-after materials and components to boost our energy security and power our homes and economy."

The construction projects focus heavily on connecting Scottish renewable energy generation to the wider grid. Key projects include the Arnish to Beauly (Western Isles) HVDC link, an offshore project that will transport 1.8GW of power from wind farms on the Isle of Lewis to Beauly in the North of Scotland. Another major undertaking is the Spittal to Peterhead 2GW HVDC Subsea link, which involves constructing a new 400kV substation at Spittal and 400kV substation at Peterhead, including 2GW HVDC converter stations in both areas, to transport energy from ScotWind farms.

Other significant construction schemes include various 400kV double circuit overhead line projects designed to increase grid capacity, such as a new 170km line between Spittal and Beauly, and a new 110km line between Beauly, Blackhillock, New Deer, and Peterhead. These infrastructure developments are critical to enabling more onshore and offshore renewable energy to be fed into the national grid and ultimately reduce the costs associated with grid constraints.
