Proposal description

1. Construction of a Gas Insulated Switchgear (GIS) compound measuring approximately 92.8m by 90.5m. The proposed GIS compound will be raised to a ground level of 1.2m higher than the existing ground level at the site, and will comprise: (i) GIS building with an approximate gross floor space 1624.1m2 and height of 15m (in addition, 6 no. lightning protection rods, approximately 3m in height, are located on the parapet of the GIS building); (ii) An internal access track measuring approximately 245m in length and 5m in width, 15 no. car parking spaces; underground stormwater attenuation tank; underground foul wastewater pumping station and all associated site development and landscaping works; and (iii) The substation compound will be bounded by a palisade fence 2.6m in height and further enclosed by a property fence measuring 1.4m in height. 2. The proposed development will also consist of the redevelopment of the existing AIS 110 kV substation, comprising the following: (i) Decommissioning of the 110 kV AIS busbar and 110 kV primary plant within the existing 110 kV AIS substation; (ii)The modification of 8 no. existing 110 kV underground circuits which will be re-routed into the new 110 kV GIS substation; and, (iii) Construction of 3no. underground joint bays; 1 no. new gantry tower (approximate footprint of 30.2m2 and a height of 12.5m); 1 no. new Line Cable Interface Mast (approximate footprint of 123m2 and a height of 20.7m); removal of the existing 110 kV OHL tower and section of cable which extends to the proposed Line Cable Interface Mast and all associated and ancillary transmission infrastructure. 3. Construction of a Distribution System Operator (DSO) compound measuring approximately 30m2; 4. Construction of a landowner access road (hardcore surfacing) of approximately 91m in length and 6m in width; and, 5. All ancillary site development works to facilitate the proposed development including geotechnical and geo-environmental ground investigations, site preparation works, site clearance and levelling, site drainage and associated outfall headwall to facilitate discharge to the River Shannon, temporary construction compounds and landscaping
