Our Transmission business is part of Scottish and Southern Electricity Networks, operating under licence as Scottish Hydro Electric Transmission plc for the transmission of electricity in the north of Scotland.

We own and maintain the 132kV, 275kV and 400kV electricity transmission network in our licence area. Our network comprises of underground cables, overhead wooden poles, steel towers and electricity substations, and it extends over a quarter of the UK land mass across some of its most challenging terrain.

We take the electricity generated from onshore windfarms, hydro power stations and other generators and transport it at high voltage and extra high voltage over long distances through our transmission network to areas of demand around our towns and cities.

Our first priority is to provide a safe and reliable supply of electricity to our communities. We do this by making sure our employees and contractors work safely while ensuring the network is able to function properly and meet electricity demand now and in the future.

Our operating area is home to vast renewable energy resources and this is being exploited by wind, hydro and marine generation. Working closely with National Grid, the GB transmission System Operator, we also enable these electricity generators to connect to the transmission system by providing their connections and allowing the electricity generated by them to be transported to areas of demand across the country.

As a natural monopoly, we are closely regulated by the GB energy regulator, Ofgem, who determine how much revenue we are allowed to earn for constructing, maintaining and renovating our transmission network in the north of Scotland. These costs are shared between all those using the transmission system, including generation developers and electricity consumers.

Holding company for electricity networks
SSE has incorporated in Switzerland a direct and wholly-owned subsidiary company to acquire, oversee and hold investments or other financial assets. The company has become the holding company for SSE’s electricity transmission and distribution networks through a share-for-share exchange. This is intended to support long term investment in low carbon infrastructure in SSE’s core businesses.
