Overview
About the Project
We are proposing to upgrade the existing 275kV east coast transmission network to enable the connection of onshore and offshore renewable electricity to Great Britain’s transmission network, allowing the onward supply of power to centres of demand. A significant number of projects are being developed on the east coast of Scotland to enable these connections and to strengthen the network serving the region.
Seagreen Wind Energy Limited (SWEL) Offshore Wind Farm requires connection to our network. To facilitate SWEL's connection, we require the extension of the existing Tealing Substation by approximately 60 x 100 metres to the east. In addition to the substation extension works, there are also planned upgrades to the current plant and infrastructure within our existing substation.
Why is the Project Required?
As the transmission network owner for the north of Scotland, we are responsible for the maintenance and development of the transmission network in an economic, efficient and co-ordinated manner. As part of our statutory and transmission licence obligations, we have a number of duties including:
- the development and maintenance of an efficient, coordinated and economical system of electricity transmission
- to facilitate competition in the supply and generation of electricity
- to ensure that the security of the network is maintained as the demand and/or generation connections change over time
We have a licence obligation to invest in our existing assets to maintain network health and condition. We also have a statutory duty under the Electricity Safety, Quality and Continuity Regulations 2002 to ensure that the electricity transmission network is fit for purpose.
Seagreen Wind Energy Ltd (SWEL)
Seagreen Wind Energy Ltd is a £3bn offshore wind farm development owned by SSE Renewables (49%) and Total (51%). Once complete, the project will take on the title of Scotland’s largest offshore wind farm with 114 turbines and a capacity of 1,075MW.
In 2010, Seagreen was awarded exclusive development rights by The Crown Estate for the Firth of Forth zone of the UK’s Round 3 offshore wind farm development programme.
Seagreen phase one within the zone includes the development of two windfarms, 'Seagreen Alpha' and 'Seagreen Bravo', located over 27km from the Angus coastline with a potential combined capacity of up to 1.5GW.
The offshore consent for Seagreen phase one was received in 2014 (confirmed in 2017 following legal challenge). In March 2018, Seagreen submitted an application to Marine Scotland seeking to remove the consented capacity limit to utilise the latest advances in wind turbine technology. This application was approved in August 2018.
In 2013, the onshore consent (Planning Permission in Principle) was received from Angus council and extended in December 2016 following re-application by Seagreen. Seagreen phase one will be, at its nearest point, located approximately 27km from the Angus coastline covering an area of around 400Km2 in the outer Firth of Forth.
The electricity will be delivered by subsea and then underground cables from landfall at Carnoustie to a new onshore substation at Tealing for onward transmission on the national electricity transmission system.

Community Engagement
Throughout the life of our projects, we aim to work positively with local communities and keep people informed about what we are doing.
We endeavour to take the time to discuss proposals with local community councils, encourage engagement from the wider community and listen to the feedback we receive.
We will do our best to answer any questions and address issues or concerns that are raised with us.
When our project progresses into construction, we will continue working closely with the local community to ensure that our work has as little impact on the lives of those living and working in the area and as many long term positive effects as possible.
How we’re embracing artificial intelligence (AI)
We intend to use AI to assist our experienced teams in the analysis of your feedback, so we can categorise key points raised more quickly. You can learn more about how we’re utilising AI on this dedicated web page.
