PROJECT DETAILS

Blackhillock Substation is an electrical substation located in the north east of Scotland, near the town of Keith in Moray.

It is owned and operated by Scottish Southern Electricity Network (SSEN). Covering an area the size of 24 football pitches, it is as of January 2019, the UK's largest substation and Europe's second biggest.

Construction began in early 2015 to upgrade the existing substation so it could accommodate the new Caithness - Moray Link. The £1bn construction project had four main elements: 400kV and 132kV gas-insulated substations, one 275kV air-insulated substation, a High Voltage Direct Current (HVDC) converter for the Caithness - Moray subsea link and a HVDC underground cable from the substation to Portgordon.

 

In January 2019 construction and commissioning were completed making it the UK's largest operating substation. It is seen as integral to the UK electricity grid as the north of Scotland generates a lot of renewable energy via windfarms.. The upgrade was primarily done to accommodate the Beatrice Windfarm.

Transmission reinforcement establishment is 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.

KITE'S PART OF THE PROJECT

Kite was proud to be part of Blackhillock success through supplying the site with GRP grating panels to secure safe access for landline cables and pipes. These GRP gratings formed protective shield panels with a clear vision to observe access points that were established to grant support for inspection, maintenance, and daily checks. The GRP Solid Tops also provided an extra enforcement to offer weight resistance and protection for specific areas of the project.
