COVID-19: Protecting our customers, our colleagues and our network

About the Project

As the transmission network owner for the north of Scotland, SSEN Transmission is responsible for the maintenance and development of the transmission network in an economic, efficient and co-ordinated manner.

SSEN Transmission is proposing to upgrade the existing 275kV East Coast transmission network to enable new generation to link to Great Britain’s transmission system, allowing the onward supply of power to centres of demand.

We are developing a significant number of projects on the East Coast of Scotland to strengthen the network serving the region and allow developers of onshore and offshore renewable electricity to connect. One of these developers being Seagreen Wind Energy Limited (SWEL).

To facilitate SWEL's connection SSEN Transmission requires to extend 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 part of its statutory and transmission licence obligations, SSEN Transmission has 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, and
  • to ensure that the security of the network is maintained as the demand and/or generation connections change over time.

SSEN Transmission has a licence obligation to invest in its existing assets to maintain network health and condition. SHE Transmission also has a statutory duty under the Electricity Safety, Quality and Continuity Regulations 2002 to ensure that the electricity transmission network is fit for purpose.

Our Approach

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.

Seagreen Wind Energy Ltd (SWEL)

Seagreen Wind Energy Ltd is an offshore wind farm development wholly owned by SSE. 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.

Who is Scottish and Southern Electricity Networks?

Scottish and Southern Electricity Networks Logo

Scottish and Southern Electricity Networks is the trading name of Scottish and Southern Energy Power Distribution Limited, Scottish Hydro Electric Transmission plc, Scottish Hydro Electric Power Distribution plc and Southern Electric Power Distribution plc.

How are Transmission network upgrades paid for?

Investments in projects are made by SHE Transmission plc. Electricity transmission companies are authorised to recover the costs of such investments through 'use of system' charges which are levied by National Grid Electricity Transmission plc on generators and suppliers of electricity. Suppliers recover their costs from all electricity customers. In order to protect the interests of customers, the transmission companies have to demonstrate to the energy regulator, Ofgem (Office for Gas and Electricity Markets) that proposed investments are necessary, are efficient and are economical so that the charges which are ultimately levied on all electricity customers are justified.


This means SHE Transmission is subject to a funding mechanism established by Parliament and regulated by Ofgem. Cross subsidies between different businesses in the SSE group is not permitted.

What is the transmission network?

It’s the highest voltage electricity network in the UK – the ‘motorway network’ of the energy world. It transmits large quantities of electricity over long distances via wires carried on a system of mainly metal towers (pylons) and large substations. Transmission voltages in Scotland are 132kV, 275kV and 400kV. Larger generation schemes usually connect to the Transmission system.

The lower voltage parts of the system are called distribution networks. In Scotland, these local networks operate below 132kV whereas in England the distribution network includes 132kV. 

How and to what extent are electricity consumers' interests considered?

SHE Transmission are regulated by the Office for Gas and Electricity Markets (Ofgem), the regulator responsible for representing consumers' interests. Electricity consumer interests are therefore one of our key drivers and this is enshrined in our statutory duties under the Electricity Act.


In particular we have a statutory duty to develop, maintain and operate an efficient, economic and co-ordinated transmission system. Since the costs of these projects will ultimately be paid for by electricity consumers, we have a responsibility to take cost into account with due weighting in a comparison against other important factors.
