Onshore construction

Operations and Maintenance Base

Seagreen requires an Operations and Maintenance (O&M) base for the duration of its 25 year operational phase.

A new, purpose built O&M base (pictured below) has been built at Montrose Port which will play an important role in the day to day running of Seagreen.

The O&M base will bring increased social benefit to the local area both in terms of employment opportunities but also in terms of the development of the O&M base itself which has been undertaken by local contractors Pert Bruce.

The image below shows the completed O&M base in Montrose.

Tealing Substation

Seagreen has built a new substation at Tealing which receives the electricity generated by the wind farm for conversion up to 400kV for onward transmission on the national electricity transmission system.

The construction of the substation has led to numerous opportunities not only in the actual construction but also in the fabrication of the component parts.

In addition, local people and businesses have benefitted from opportunities such as the provision of plant and materials and other services such as accommodation and food for the site operatives.


The image below shows the Seagreen substation in the foreground with the electricity network substation behind, through which Seagreen sends its electricity to homes and businesses. 


Onshore cabling

The electricity generated by the Seagreen turbines is transmitted via subsea export cables to a landfall at Carnoustie.  Once ashore, the electricity is then transmitted from Carnoustie to our new Tealing substation via underground cables for a distance of approximately 19km.

The installation of the underground cables was undertaken by various specialised operatives and machinery including Horizontal Directional Drilling (HDD) equipment where the cables need to pass under road, rail or other sensitive areas.

The use of this technology enabled the installation of the cables with the minimum of disruption.


The installation of the cables has also provided significant employment and business opportunities.
