The development will be bound by 2.4m high perimeter fencing. The application is accompanied by a Natura Impact Statement (NIS)

Development consisting of (a) A High Inertia Synchronous Compensator (HISC) compound containing 1 No. HISC unit enclosed within a steel clad framed style structure (12.1m max height) and supported by 7 No. electrical equipment containers (containing ancillary power supply products including static frequency converters, MV switchgear, exciters, LV distribution, control room); 4 No. external cooler units; main, auxiliary & start-up electrical transformers, generator circuit breakers, switchgear equipment, and 1 No. back up diesel generator and associated diesel storage tank; (b) A 220kV High Voltage Gas Insulated Switchgear (GIS) compound containing a GIS building with all control & HV equipment within a single storey building (13.2m max height). The building will be surrounded by a compound road and contained within a 2.6 high galvanised steel palisade fence; (c) A 220kV underground cable to the existing adjoining Eirgrid substation boundary; (d) New access road and entrance from the L5204; (e) All associated and ancillary site works necessary to facilitate the development including: all necessary drainage systems, foundations works for the above compounds, various underground cables and ducts, equipment plinths, internal services roads, rainwater harvesting systems, welfare and office units, 2 No. material storage containers, compound lighting and palisade gates and fencing, security lighting, CCTV, hardstanding areas and boundary security fence. Planning permission to construct the development is sought for a period for 10 years. A Natura Impact Statement (NIS) has been prepared in respect of the proposed development and accompanies the application.

Development consisting of a 10 year permission. The development will consist of the development and operation of a 250 to 300 MVA (electrical rating) synchronous condenser. The development which will be located within a site compound of c. 1 hectare and will consist of the following elements: A Condenser and Control Building to house equipment including the synchronous condenser, flywheel, lube oil skid system, air compressor and pumps. Equipment to be located outside the footprint of the Condenser and Control Building but within the fenced compound will include: Cooling equipment (c. 160 sq m., c.3m high); 6 No. modular containers to house electrical and control equipment (total area of c. 195 sqm., c. 5m high); A step-up transformer, auxillary transformer and electrical plant including an external circuit breaker; 1 No. firefighting water tank; A below ground oil interceptor and attenuation tank in lieu of the originally proposed above ground oil interceptor and collection pit.
