2 Scottish and Southern Electricity Net Project Overview Offshore Wind Grid Connection Who we are Scottish Hydro Electric Transmission Plc (SHE Transmission) Scottish Hydro Electric Power Distribution Plc (SHEPD) Other SSE Businesses Southern Electric Power Distribution (SEPD) Our licence stipulates that we must develop and maintain an efficient, co-ordinated and economical system of electricity transmission. What is the difference between Transmission and Distribution? Electricity Transmission is the transportation of electricity from generating plants to where it is required at centres of demand. The Electricity Transmission network, or grid, transports electricity at very high voltages through overhead wires, underground cables and subsea cables. The transmission network connects large scale generation, primarily renewables, to central and southern Scotland and the rest of Great Britain. We are the licensed owner of the electricity transmission network in the north of Scotland. Operating under license means that we have certain obligations that we must fulfil. These obligations include maintaining the existing network to ensure that the lights stay on and investing in the network to provide the infrastructure needed to allow generation developments to connect it. The transmission network gathers energy in from power stations, hydro-electric generation schemes and wind farms and carries it to areas where it is to be used. We work with the Transmission System Operator, National Grid, who is responsible for operating the transmission network across the whole of Great Britain, to make sure that power flows smoothly and reliably across our network. A request has been made to National Grid by the developer of Offshore Wind to provide a connection to the transmission network. We are currently contracted to provide a 32 kv connection running from the consented wind farm s onshore substation at Blackdog to the existing nearest point on the 32 kv network at Dyce substation. We are part of Scottish and Southern Electricity Net, operating under licence as Scottish Hydro Electric Transmission Plc for the transmission of electricity in the north of Scotland. In total we maintain about 5,km of overhead lines and underground cables easily enough to stretch across the Atlantic from John O Groats all the way to Boston in the USA. Our network crosses some of the UK s most challenging terrain including circuits that are buried under the seabed, are located over 75m above sea level and up to 25km long. The Electricity Distribution network is connected into the Transmission network but the voltage is lowered by transformers at electricity substations, and the power is then distributed to homes and businesses through overhead lines or underground cables.

There is a high demand to connect from new wind, hydro and marine generators which rely on Scottish and Southern Electricity Net to provide a physical link between the new sources of power and electricity users. Scottish and Southern Electricity Net is delivering a major programme of investment to ensure that the network is ready to meet the needs of our customers in the future.

We are issued with a licence to operate and we must adhere to the terms of the licence. For this reason we operate on a very separate basis to other SSE businesses.
