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

Lanesboro Generating Stat Aghamore Td. Lanesboro, Co. Longford
New 110 KV Station Control Building, including additional control cable ducting, realignment and replacement of the existing compoung fence, and replacement of switchgear, within the boundary fence
development at this site - the existing Cloon to Lanesboro 110 kV Overhead Line is approximately 65 kilometres long. Approximately 37km of the existing circuit is located within the functional area of Galway County Council with approximately 27km located in County Roscommon and approximately 120 metres located in County Longford. The refurbishment works within County Longford will be undertaken at structure EM365, located within the Lanesboro Substation in the townland of Aghamore (Rathcline By). The development will consist of the refurbishment of the Cloon - Lanesboro 110 kV Overhead Line which will primarily include: replacement of a large proportion of existing structures, the breaking out and reconstruction of the concrete foundation and shear blocks at the majority of end/angle mast structures, painting of mast structures, replacement of insulators, crossarms, stays and/or fittings on existing structures; and the fitting of bird flight diverters and stay guards. No additional structures are proposed along the existing circuit. Any replacement structures will be constructed at, or immediately adjacent to the existing structures they will replace, and will be of a generally similar height and appearance. Associated site development works to gain access to the existing structures include clearance of vegetation, disassembly and reassembly of stone walls and gate posts and removal and reinstatement of existing fencing. The proposed development includes all other associated and ancillary site development works required for the refurbishment of the existing circuit, including the installation of temporary silt traps, silt fences, bog mats and clear span bridges. No additional structures and no alteration to the nature, extent, alignment, character or voltage of the existing electricity infrastructure is proposed.
