About the Project
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 HVDC converter
- An underground HVDC electricity cable from Blackhillock to Portgordon
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.

Transformer Delivery Images 2017
Four supergrid transformers that will play a vital role in the north of Scotland’s future electricity network made the final stage of their journey from Buckie Harbour to Blackhillock substation near Keith, throughout July 2017.
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 us and our lead contractor ABB.
