About the Project

The two 25MVA 132/11kV grid transformers at Lochay power station were manufactured in 1958 and form an important part of the SHE Transmission system. The power station is supplied from the Killin 132/33kV grid substation through the 132kV single overhead line.

These transformers have reached their intended operational capabilities, and recent condition assessments also indicate that there is a need to replace both transformer units.





Why is the Project Required?

SHE 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.

The decision making process for asset replacement takes into account both the criticality and condition of existing assets. Criticality is a representation of the risk to stakeholders with respect to safety, environment and reliability. The decision making process has been agreed with the regulatory stakeholders and has been taken into account in prioritising the Lochay transformers for further assessment and asset replacement.

Pre-Application Consultation

We will be submitting a planning application to Stirling Council for a 132kV substation in Lochay adjacent to the existing Lochay power station.

We would like to extend an invitation to local members of the community and interested parties to attend an exhibition to discuss our plans with the project team and let SSEN know their views on the proposal.

Who is Scottish and Southern Electricity Networks?

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.

How are Transmission network upgrades paid for?

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.

What is the transmission network?

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. 

Public Exhibition

Scottish and Southern Electricity Networks (SSEN) are taking forward plans to replace the two 25MVA 132/11kV grid transformers at Lochay power station. As such we are hosting a public exhibition on Thursday the 9th May 2019 between 2-7pm to provide greater detail about this project.

Proposal of Application Notice

We have now submitted the Proposal of Application Notice (PAN) to Stirling Council under the terms of the Town and Country Planning (Development Management Procedure)(Scotland) Regulations 2013. This notice states our intent to submit a planning application to erect an electricity substation adjacent to the existing Lochay hydrostation.
