Site planning risk brief

Construction of a battery storage compound including 2 no. battery storage buildings with associated plant and equipment, an ancillary 110kV electricity substation with 2 no. control buildings, associated electrical plant & equipment and fencing, underground electricity cabling, surface water drainage, site entrance and access track, security fencing and all ancillary site works. Extension of Duration to Permission granted under Planning Ref. No. 18/5686

Construction of a battery storage compound including 2 no. battery storage buildings with associated plant and equipment, an ancillary 110kV electricity substation with 2 no. control buildings, associated electrical plant & equipment and fencing, underground electricity cabling, surface water drainage, site entrance and access track, security fencing and all ancillary site works.

Proposed modifications to the previously permitted development (planning ref: 18/06438 granted on 7th March 2019).The proposed modifications will comprise the additional construction of one (1) harmonic filter, one (1) HV circuit breaker (including CT and VT), one (1) MV disconnector and earth switch, two (2) cable sealing ends, three (3) additional lightning masts (approximately 25m high) and additional lamppost lightning. It further includes a retaining wall (approximately 2.5m high), asphalt (non-permeable) surfacing, additional permanent access road, additional fencing to match existing 2.6m high palisade, additional permanent access gate and all other ancillary site development works. The development will remain an extension to the existing substation and this extension will have an overall site area (within the planning application boundary) of 0.73ha. Access will continue to be provided via a L5226 and the R582.

The proposed development will comprise the construction of one (1) no. ± 100 Mvar STATCOM transformer, one (1) no. auxiliary transformer, three (3) no. reactors, one (1) no. outdoor cooling bank, control and valve building (268m²), underground connection to existing ESB substation. It further includes security fencing, security gate, four (4) no. 25m high lightning masts, permeable surfacing, and an internal access road. There will also be the construction of one (1) no. temporary contractors' compound. The development is an extension to the existing substation and the overall site area (within the planning application boundary) is 0.73ha. Access is provided via a local road (L5226) onto the R582.

A battery energy storage facility which will comprise of rechargeable battery units contained within up to 39 No. 40 foot containers on site and the associated development of unit substations, a 110 kV substation, security fencing, security cameras, lightning mast, new site roads and the upgrading of the existing vehicular access. The facility will connect into the adjoining Ballyvouskill ESB substation via underground cable. All associated site development, landscaping and boundary treatment works above and below ground.

Permission is sought for a battery energy storage system which will comprise of up to 15 no. BESS units comprising of battery cells within modules stored in racks on concrete bases and ancillary equipment (4 no. BESS containers within each BESS unit); an individual unit transformer at each BESS unit with some additional ancillary equipment, a transformer compound, control building (including control room and switch room), interface kiosk and all associated electrical infrastructure equipment and works, attenuation drainage pond to southeast of the BESS site, a temporary site compound and all associated works(to be located to the south of the BESS site); upgrade of existing vehicular access to local road and all associated internal access tracks, 2.4 metre high chain link fencing and associated landscaping along the perimeter of the development, 2.4m metre high palisade fencing along the perimeter of the transformer compound, associated electrical underground cabling and ducting works facilitating the connection of the proposed site to the Ballyvouskill transmission station, all associated site development, lighting, landscaping, CCTV, security fencing, boundary treatment works above and below ground and all associated ancillary infrastructure.
