About the project

The existing Fetteresso substation was fully constructed in 2016 to operate at a voltage of 275kV, with the intention of upgrading to 400kV in the future. The aim of this new project is to now upgrade the substation to operate at 400kV. The project elements include:

 

  • Replacement of existing 275kV transformer (1 no.) with 400kV transformers (2 no.)
  • Replacement of existing 275kV equipment such as Surge Arrestors and Capacitive Voltage Transformers with 400kV equivalents;
  • Any associated works (i.e. nomenclature changes, protection updates, etc.)

 

The transmission system in both the North East and East Coast of Scotland will be upgraded to 400kV over the next decade, in order to facilitate this, SSEN Transmission are proposing both upgrading the existing overhead line network in the region and installing new substations at various points.

 

These works are required to allow increased generation capacity access to the transmission system, while keeping the network fully operable and compliant with all necessary technical standards. Without these necessary reinforcements, the network cannot facilitate all generation connections.

Upgrading the existing substation at Fetteresso addresses this issue and in effect increases the networks efficiency and capability. Power sharing across these circuits becomes more important as generation load increases on the system.

The construction works will be contained to the existing site boundary and are expected to take place from approximately summer 2024 through to late 2026.

Our Engagement

 

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 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.

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.

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 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.

Project update - February 2022

Over the next 12 months the project team will be engaging with a number of consultants and contractors to undertake specialist survey works on site such as transport assessments and birds surveys. These surveys will help inform the substation development before the project team engage with a Substation Contractor to undertake the construction works.
