The electricity generated by the Seagreen wind turbines is brought ashore via around 40km of subsea export cables to a landfall point at Carnoustie via around 40km of subsea cables.  The subsea cables are connected to around 19km of underground cables that take the electricity to our substation at Tealing and then on to the National Electricity Network for distribution to homes and businesses.

The map below shows the onshore cable route from Carnoustie to Tealing.
 

The installation of the c.19km of underground cables has been undertaken by Nexans, responsible for the design, supply and installation of both the offshore and onshore cabling.

The process has included:

​

• Construction of temporary access points, haul roads and access roads

• Creation of temporary construction compounds and storage areas

• Excavation of trenches and installation of cable ducting

• Excavation of cable 'pits'

• Installation of 'joint bays'

• Laying of cables through the installed ducting

• Reinstatement of the ground once installation is complete

​​

The installation of the onshore cable has been a significant feat of engineering with 117 individual cables being installed and connected along the route.  And our contractors utilised HDD (Horizontal Directional Drilling) to install the cables under features such as the East Coast Mainline railway, the A90 and A92 roads and watercourses which avoided the potential for significant disruption. 

​

Installation of the cables was completed in June 2022.
