The proposed development consists of the following principal elements:
A. Offshore renewable energy infrastructure in the outer maritime area located between approximately 6 km south of Cooley Point and approximately 10 km north-east of Dunany Point across an offshore wind farm area of approximately 27.7 km2 and consisting of the following:
i. 25 No. offshore wind turbines with a maximum tip height of 270 m above the Lowest Astronomical Tide (LAT) attached to the seabed by monopile foundations with associated scour protection and with a combined Maximum Export Capacity of 375 MW.
ii. A network of 41 km of 66 kV subsea inter-array cables linking each of the proposed offshore wind turbines to the offshore substation including associated cable protection.
iii. 1 No. offshore substation with a height of 48 m above LAT attached to the seabed by a monopile foundation with associated scour protection. This includes a prefabricated structure containing electrical equipment and ancillary equipment including a telecommunications mast.
B. A single 16 km long 220 kV subsea export cable and associated cable protection located within an offshore cable corridor of approximately 25 km2 between the south-west corner of the offshore wind farm area and a landfall which is situated approximately 700 m south of Dunany Point.
C. An underground Transition Joint Bay (TJB) at the proposed landfall in the townland of Dunany. The TJB consists of a fully buried concrete chamber with a total area of 32.5 m2, where the proposed offshore
export cable will be connected to the underground onshore export cables.
D. Installation of underground onshore export cables, approximately 20.1 km in length, connecting the proposed TJB in the townland of Dunany to the proposed onshore substation in the townland of
Stickillin. The cables will be laid in a standard trench of approximately 700 mm in width and 1425 mm in depth.
E. Installation of fibre optic, telecommunication and other associated cabling all carried in underground ducts within the proposed trench.
F. Installation of 2 No. additional fibre optic cable ducts within the underground cable trench of approximately 1500 mm in width, from the proposed onshore substation in the townland of Stickillin along the N33 for approximately 3 km and connection into a 110 kV double wooden poleset on the existing Drybridge-Louth 110kV overhead line in the townland of Richardstown, (Electoral Division of Stabannan).
G. Installation of the cables will require associated joint bays and link boxes, located at approximately 700 m intervals along the underground cable alignment. The cable installation will also require the construction of temporary passing bays and the use of either Horizontal Directional Drilling (HDD) or open cut construction techniques for utility crossings of water, rail, gas and motorway.
H. A new onshore electricity substation adjacent to the proposed connection point in the townland of Stickillin. The onshore substation will comprise of the following main elements: 
i. Compound 1 Onshore Transmission Connection.
ii. Compound 2 Offshore Transmission System.
iii. Entrance Compound providing access to Compound 1 and Compound 2.
iv. Common Areas.
I. 2 No. line cable interface masts of 27 m in height will be constructed adjacent to the onshore substation. This will require an existing 220 kV tower (31 m in height) and associated infrastructure to be decommissioned.
J. A temporary construction compound adjacent to the onshore substation with a footprint of approximately 12,860 m2 including welfare and storage areas. 3 No. additional temporary construction compounds
located along the onshore cable route varying in footprint from 3,000 m2 to 4,200 m2 and 8 No. temporary HDD compounds (4 off road HDD’s) varying in footprint from 100 m2 to 4,500 m2.
K. All associated and ancillary above and below ground development including works comprising or relating to construction works, roadworks, excavation (including HDD) and vegetation clearance.
Planning permission is sought for a period until the expiry of the Maritime Area Consent for the Project on22 December 2067.
