Blackhillock Substation

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[clarification needed] substation and Europe's second biggest.

[1] Construction began in early 2015 to upgrade the existing substation so it could accommodate the new 1,200 MW Caithness - Moray Link.

[3] 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 much renewable energy via windfarms.
