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.

There is potential for travel disruption during construction, when we take delivery of key plant items or because of increased volumes of traffic on the local road network. Disruption will be minimised and typically controlled through an agreed Traffic Management Plan with Perth and Kinross Council as part of any consent conditions. SHE Transmission aims to ensure that construction traffic uses the roads safely and that any inconvenience to the public is kept to a minimum whilst maintaining a safe environment for the workforce and other road users.

As part of the Environmental Assessments, potential impact from construction noise will be evaluated and mitigation measures instigated where necessary.

A flood assessment was carried out on the substation site and we don’t foresee any flooding. The substation site is out with the 1 in 1000 year flood event zone and the finished platform level has a 2 metre freeboard above the 1 in 1000 year flood event.

As part of the planning application process, PKC will notify all residential properties within 20m of the application site. In addition, they may choose to consult SEPA on the application and if that happens we shall work with them on any issues raised.

Yes. Every effort will be made to keep the Haughend Road open during the Public Road Improvement works. Small closures for example to remove the disused railway bridge will be required so local route diversions may be required.

SHE Transmission are upgrading the Haughend Road as part of the works and will maintain the road in agreement with the planning condition set by PKC.

The substation access will be located at the north west corner of the site.

As part of the planning process we will agree construction operational working hours with Perth and Kinross Council. Construction works will only take place during these agreed hours and in planning the works, our contractors will look to minimise the impact of construction noise on neighbours and the public.
