Transformer delivery images - July 2017

Four supergrid transformers that will play a vital role in the north of Scotland’s future electricity network are set to make the final stage of their journey from Buckie Harbour to Blackhillock substation near Keith, throughout July.

The transformers, which each weigh approximately 245 tonnes, have been delivered by sea from Sweden to Buckie Harbour where they are due to be loaded on to multi-axle trailers by specialist haulier Allelys, working on behalf of Scottish and Southern Electricity Networks (SSEN) and its lead contractor ABB.

We have published some of our images here. If you would like to add your own photos, please email them to lesley.dow@sse.com

Project overview

An expanded substation and a High Voltage Direct Current (HVDC) Converter Station are in construction at the site of the existing electricity substation at Blackhillock, near Keith, Moray.

The main elements of the project are as follows:

  • a 400kV GIS (gas-insulated substation);
  • a 132kV GIS substation;
  • a 275kV AIS (air-insulated substation);
  • a High Voltage Direct Current (HVDC) converter;
  • an underground HVDC electricity cable from Blackhillock to Portgordon

Blackhillock 400/275/132kV Substation (AC)

The new substation will be capable of carrying up to 1200MW of electricity between Caithness and Moray. It is made up of eight bays of 132kV Gas Insulated Switchgear (GIS), thirteen bays of 275kV Air Insulated Switchgear (AIS) and ten bays of 400kV Gas Insulated Switchgear (GIS), two 360 MVA Power Transformers. Two 530 MVA cables are being installed between Blackhillock and Keith substations to reinforce the network.

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.
