Case Studies

Seagreen, a joint venture between TotalEnergies (51%) and SSE Renewables (49%), is poised to become Scotland's largest and the world's deepest fixed foundation offshore wind farm. Its wind turbines generate electricity offshore, which is then transmitted via around 40 kilometers of subsea export cables to Carnoustie. From there, about 19 kilometers of underground cables carry the electricity to the Tealing substation, connecting it to the National Electricity Network for distribution to homes and businesses. Nexans was responsible for installing these underground cables, which crossed major infrastructure like the East Coast Mainline railway, the A90, A92 roads, and various watercourses.

Kilmarnock South Substation is situated to the south east of Kilmarnock and plays a crucial part in the Transmission Network forming a hub for a number of key overhead lines. SP Energy Networks (SPEN) have a key strategic role in the connection of renewable generation in Scotland and as a result, a significant level of activity on the Transmission Network was required to facilitate these connections along with other demands for greener technologies, including electric vehicles and decarbonised heating such as heat pumps, all of which will be pivotal as the country pushes towards achieving its bold net zero emissions target. The £60million modernisation and upgrade of this substation was a key part of their Network Reinforcement Programme. The significant programme of work which commenced in 2016, and was completed in 2021, will ensure the substation continues to operate effectively and efficiently for decades ahead, supporting the nations move to a net zero.
