Glenlee – 132KV Civils & Balance of Plant
The works at Glenlee form part of the Kendoon to Glenlee Reinforcement, which includes the extension of the 132kV network in south west Scotland.
The RIIO‐T1 shunt reactor modernisation programme has identified the need to replace the
existing oil filled shunt reactors (R1 & R2) at Smeaton 400/275/132kV substation. The new
Shunt Reactors will have nominal capacity rating of 60MVAr.

The contract scope for these Balance of Plant works required at Crystal Rig 400kV substation was to facilitate the Neart Na Gaoithe offshore windfarm connection.
NRS Group were required to supply, handle, install, test & commission all equipment
Erskine 132kV substation was commissioned in 1972 and has been in continual service since without having any major upgrades. All associated primary equipment remains the same as originally installed at the time of the grid transformers.
SGT2 was commissioned in 1969 and was fitted with a masonry noise & fire enclosure. This was replaced by like for like 120MVA grid transformer including new noise & fire enclosures.
The RIIO‐T1 shunt reactor modernisation programme has identified the need to replace the existing oil filled shunt reactors (R1 & R2) at Smeaton 400/275/132kV substation.
Kincardine substation was identified as being at risk from flooding during a number of storm events, it is therefore proposed the sub-station is re-built
The Contract consisted of a combined Civils and Balance of Plant contract to install new foundations, structures, 400kV surge arresters, PTI’s and cable sealing ends in the Torness – Branxton 400kV circuits at Branxton 400kV substation.
