About the project

The weather in and around the Shetland Isles is considered to be very productive for renewable energy generation. There is currently >500MW of generation proposed that would require a mainland connection if constructed and recent developments in relation to available government funding for generators on islands has increased the possibility that these projects will be progressed. Scottish and Southern Electricity Networks has a transmission licence requirement to provide connection to the UK’s network when requested by a generator.

The aim of the Shetland project is to allow for the export of renewable energy generation from Shetland to the UK mainland, connecting Shetland to the Nation’s Electricity Transmission System for the first time.

The project proposal will consist of a high voltage direct current (HVDC) link. including approximately 260km of cabling, all but 10km of which will be in the sea. A 320/132kV substation and HVDC convertor station will be required, proposed at Upper Kergord on Shetland. An HVDC Switching Station will also be necessary to facilitate connection to the existing Transmission system at Noss Head in Caithness.

 

 

 

Public Consultation – Marine HVDC Cable

Members of the project development team are working towards a detailed design for the subsea cable which will link Shetland to the Scottish Mainland and are aiming to submit a Marine License Application Submission by the end of this year. A pre-application public consultation shall be held prior to this to provide further information to local stakeholders.

Details of the proposals from the previous public consultation events are available to download via the ‘Project Documentation’ section of this page.

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.

How are our 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?

We 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. 

Team Site Visit - February 2018

Having recently introduced some fresh faces to our Shetland Project Team, we arranged a site visit earlier this week to introduce ourselves and to provide an update to local stakeholders, Tingwall, Whiteness and Weisdale Community Council and our colleagues in Operations based in Lerwick Power Station. We also took the opportunity to revisit the planned substation location at Upper Kergord, the proposed subsea cable landing point at Weisdale Voe and our engineers took full advantage of the sunny weather by walking the planned cable route between the two. If you would like a copy of the project update presented this week please see the 'Project Documentation' tab for a download of the Power Point.

Consultation on treatment of non-mainland GB onshore wind projects

We have today responded to the UK Government consultation on treatment of non-mainland GB onshore wind projects, to read our response please go to the ‘Project documentation’ section of the project website
