About the Project

SHE Transmission is developing a significant number of projects in the North East and East Coast of Scotland to strengthen the network serving the region and allow developers of onshore and offshore renewable electricity to connect.

The East Coast 400kV Upgrade is the second part of the phased onshore reinforcement on the East Coast– the first part is the East Coast Onshore 275kV Upgrade. These onshore reinforcements comprise of works on existing infrastructure in both the Scottish Hydro Electric Transmission Plc (SHE-Transmission) and Scottish Power Transmission (SPT) area, with the majority of the works in the SHE Transmission area.

The East Coast 400kV Upgrade, comprises of:

  •  Works at Blackhillock, Kintore, Fetteresso and Alyth substations (These will be under separate projects).
  • Re-insulation and re-conductoring of overhead lines (OHLs) between Kintore, Fetteresso, Alyth and Kincardine (in SPTs area)

Corresponding works will be undertaken in a coordinated manner by SPT in their licence area.

Why is the Project Required?

As part of its statutory and transmission licence obligations, SHE 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.

SHE 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. This is particularly important when we are developing a proposal and we want to understand what local people think about our plans.

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.

Who is Scottish and Southern Electricity Networks?

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 are proposals scrutinised?

The Scottish Ministers are responsible for determination of applications submitted under Section 37 of the Electricity Act 1989. Both statutory consultees and members of the public have the right to submit their representations on the application. All representations will be considered by Scottish Ministers in their determination of the application.
The Office for Gas and Electricity Markets (Ofgem), as the regulator, has to approve all investment so project proposals are developed under license conditions.
Preferred route corridors chosen will comply with revised ‘Holford Rules’ which are the recognised industry approach to routeing overhead lines amended to reflect Scottish circumstances.

Scoping Report

We have sought a scoping opinion from the Scottish Government for the proposed East Coast 400kV Overhead Line Upgrade. Copies of the scoping request and supporting information can be accessed within the project documentation tab. The purpose of the scoping request is to establish the scope of the Environmental Impact Assessment Report.
