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.
