Substation Modernisation and Reinforcement

As the Licensed Transmission Owner for Central and Southern Scotland, SP Transmissions owns and maintains over 130 high voltage substations that operate at 400, 275 and 132kv and are   a crucial part of the Transmission Network which transports clean energy around the country.

Throughout the Covid 19 pandemic we have continued to work on our substation projects ensuring they operate efficiently and play a key part in the transportation of electricity around our area and beyond. Transformers situated within the substations allow high voltage electricity to be reduced to the supply level used by us all at home and work. A significant part of our ongoing investment is directed at the modernisation and reinforcement programmes for substations as we make every effort to deliver a safe, reliable and economic service.

The substations are continually monitored and inspected allowing the equipment approaching end of life to be identified and replaced with more efficient apparatus as part of our modernisation programme. The majority of this work is carried out within the confines of the substation itself with little or no effect on the surrounding community.

At certain locations the demand placed on our network has increased necessitating the reinforcement of substation equipment to facilitate the larger capacity required. At times, if the increased demand reaches a certain level, substations may need to be extended or occasionally a newly built substation is the only option. The planning and delivery of these projects takes place over a number of years with work either currently ongoing or due to take place at a number of the Transmission Network Substations including  Wishaw, Kincardine, Glenlee, Kilmarnock, Kaimes and Currie along with many others.

SP Energy Networks are proud of the important part they play in the countries move to a zero carbon and more sustainable society.
