Scottish Hydro Electric Transmission Plc is proposing to upgrade the existing 275kV east coast transmission network to enable new generation to link to Great Britain’s transmission system, allowing the onward supply of power to centres of demand.
There is currently a 275kV overhead line (OHL) T-junction tower at Haughend near Alyth, and as part of the upgrade a new substation including reactive compensation (equipment to stabilise network voltage) is proposed at this location. This new substation will operate at 275kV but will be built for 400kV capability.
Scottish Hydro Electric Transmission Plc has a licence obligation to invest in its existing assets to maintain network health and condition. SHE Transmission Plc also has a statutory duty under the Electricity Safety Quality and Continuity Regulations 2002 to ensure that the electricity transmission network is fit for purpose.
This strategic grid reinforcement is deemed to be essential for providing the transmission capacity necessary to realise the potential of Scotland’s renewable energy resources, maintaining long-term security of electricity supply supporting sustainable economic development.
We are intending to submit a planning application to Perth and Kinross Council for a new 275/400kV electricity substation approximately 450 metres north west of Haughend Farm, Meigle. The substation was first granted planning permission in December 2012, however due to changes in the proposed design we will submit a new planning application taking account of these changes.
We would like to extend an invitation to local people and interested parties to attend an exhibition to discuss our plans with the project team and let us know their views on the proposals.
Scottish and Southern Electricity Networks is the trading name of Scottish and Southern Energy Power Distribution Limited, Scottish Hydro Electric Transmission plc, Scottish Hydro Electric Power Distribution plc and Southern Electric Power Distribution plc.
Investments in projects are made by SHE Transmission plc. Electricity transmission companies are authorised to recover the costs of such investments through 'use of system' charges which are levied by National Grid Electricity Transmission plc on generators and suppliers of electricity. Suppliers recover their costs from all electricity customers. In order to protect the interests of customers, the transmission companies have to demonstrate to the energy regulator, Ofgem (Office for Gas and Electricity Markets) that proposed investments are necessary, are efficient and are economical so that the charges which are ultimately levied on all electricity customers are justified.
This means SHE Transmission is subject to a funding mechanism established by Parliament and regulated by Ofgem. Cross subsidies between different businesses in the SSE group is not permitted.
It’s the highest voltage electricity network in the UK – the ‘motorway network’ of the energy world. It transmits large quantities of electricity over long distances via wires carried on a system of mainly metal towers (pylons) and large substations. Transmission voltages in Scotland are 132kV, 275kV and 400kV. Larger generation schemes usually connect to the Transmission system.
The lower voltage parts of the system are called distribution networks. In Scotland, these local networks operate below 132kV whereas in England the distribution network includes 132kV.
SHE Transmission are regulated by the Office for Gas and Electricity Markets (Ofgem), the regulator responsible for representing consumers' interests. Electricity consumer interests are therefore one of our key drivers and this is enshrined in our statutory duties under the Electricity Act.
In particular we have a statutory duty to develop, maintain and operate an efficient, economic and co-ordinated transmission system. Since the costs of these projects will ultimately be paid for by electricity consumers, we have a responsibility to take cost into account with due weighting in a comparison against other important factors.
