Development at the 13.1 Ha site known as 'Lough Ree Power (LRP) Station' located in Lanesborough (Lanesboro), in the townlands of Aghamore and Lanesborough, Eircode N37E180; in County Longford. The development will consist of the demolition of the existing LRP station (as approved under Longford County Council reg.ref 01/115 ' An Board Pleanala Ref. PL14.125540 and all subsequent permissions);and the development and operation of electricity grid services - namely a battery energy storage system (BESS) and a Synchronous Condenser (Sync Con). The proposed development comprises two distinct phases of activity - the initial demolition and site reinstatement (Phase 1); following by construction and operation of the new BESS and Sync Con (phase 2). Phase 1 comprises the demolition of existing site structures (with a total footprint of c. 11.195sq.m. and a total gross floor area of c. 20,000 sq.m) including the former LRP station (boiler house, turbine house, bag filter house and associated 80 m high stack); the intermediate peat storage building and associated fuel management system; and ancillary buildings including, electrical building, tippler building and associated control room and office, the screening building, lorry uploading building, water treatment plant building, offices building, laboratory building, workshop and maintenance buildings, oil pumphouse, electrics rooms, railway/locomotive service building, cooling water pump house and sewage/foul water treatment facility. All buildings and structures (including storage tanks and vessels) will be demolished to ground level, with below ground voids filled. Existing hard standing surfac3es (e.g. building ground floor concrete slabs, tarmacadam surfaces, concrete footpaths and road kerbs) will remain in site; and the site will be reinstated and secured with boundary gates and fences, etc. Associated with the demolition activity there will be on-site crushing of material using mobile machinery for the purposed of disposal and/or material re-use.
