Substation extension

The proposed extension covers an area of approximately 90m x 40m, primarily to the south west of SPEN’s existing substation site.

The proposed extension site is bounded to the north by the existing hydropower station and substation and local road, to the east by residential housing and a local road, to the south by undeveloped green field land, and to the west by the penstock of the Glenlee Power Station and undeveloped green field land.

The work will include a new 2.74m steel palisade security fence around the perimeter, new electrical switchgear and plant to connect the proposed new KTR overhead lines, and drainage works to divert the existing watercourse that crosses the field into a culvert underneath the substation.   

We also plan to create two temporary construction compounds, which will be reinstated to their former condition following our work. These compounds will not be part of our planning application because they are classed as ‘permitted development’.

During public consultation on the proposals in March and April 2018, we were asked to investigate whether we could build the substation extension further away from local properties. Since then we have carried out a detailed appraisal of possible alternatives, which has concluded that our original proposal remains the most economic, efficient and sustainable solution.
