  • Where we operate

  • Scottish and Southern Electricity Networks is the owner of two electricity networks and one transmission network.

    • Southern Electric Power Distribution ltd in central southern England.
    • Scottish Hydro Electric Power Distribution ltd in the north of Scotland.
    • Scottish Hydro Electric Transmission ltd in the north of Scotland.


    In addition to our primary operating areas where we have a monopoly, we have installed a number of individual distribution networks across Great Britain which we also manage.

    Scottish and Southern Electricity Networks - Central southern England

    This is the largest of our two distribution networks and delivers electricity supplies to over 2.9 million customers across central southern England. Our operational region ranges from rural communities in Hampshire, Dorset, Wiltshire, Gloucestershire and Oxfordshire to towns and cities including Bournemouth, Oxford, Portsmouth, Reading, Southampton, Slough, Swindon and in parts of west London. We also distribute electricity to and across the Isle of Wight.

    Scottish and Southern Electricity Networks - Northern Scotland

    We deliver electricity to some 740,000 customers in the north of Scotland. Our SHEPD operating region covers a quarter of the UK landmass which attracts unique challenges both in terms of distance and location. As well as the major towns and cities of Aberdeen, Dundee, Inverness and Perth, we connect to most Scottish islands with over 100 subsea cable links, including the Inner and Outer Hebrides, Arran and the Orkney Islands. We also serve the Shetland Islands, which runs as a separate electrical system without a connection to the mainland.

    Scottish Hydro Electric Transmission (SHE Transmission)

    SHE Transmission owns and maintains the 132kV and 275kV electricity transmission network in the north of Scotland, in some of the UK's most challenging terrain. Some of our circuits are situated over 750 metres above sea level and are up to 250 km long. Furthermore, our operating area contains a vast renewable energy resource and this is being exploited by wind and marine generation which is all dependent on SHE Transmission for transportation to the load centres to the south.

    On 2 September 2010 SHE Transmission began a period of consultation to seek views on the future of electricity transmission in the north of Scotland. More details about our plans for our transmission network on available on the Transmission Price Control Review pages.
