Work No. 7 — a foreshore connection consisting of an extension of the electrical circuits comprised in Work No. 6, including cable crossing works, crossing under the existing sea wall using the horizontal directional drilling method and terminating at the electrical circuit transition joint bays (Work No. 8).
Onshore works
Work No. 8 — up to four underground electrical circuit transition joint bays in the vicinity of Horseshoe Point in the parish of North Coates in the county of Lincolnshire, housing the connections between the offshore and the onshore electrical circuits.
Work No. 9 — a connection consisting of two underground transmission electrical circuits if the mode of transmission is HVDC and up to four underground transmission electrical circuits if the mode of transmission is HVAC. The connection proceeds—
(a)from Work No. 8 at co-ordinate: Easting 537791, Northing 402441; to
(b)Work No. 10 at co-ordinate: Easting 514992, Northing 419274.
Work No. 10 — an electrical transmission station including a building abutting an open yard (which may be partitioned with concrete or steel walls or fences containing switchgear, electrical reactors and other electrical equipment) on land adjoining the North Killingholme National Grid substation. If the electrical circuits comprised in Works Nos. 6, 7 and 9 are HVDC, the electrical transmission station will include facilities to convert the current to HVAC.
Work No. 11 — a connection consisting of up to two underground electrical circuits between Work No. 10 and the North Killingholme National Grid substation, including a connection above ground and electrical engineering works within the National Grid substation buildings and compound.
Work No. 12 — improvements to the verge, highway and private access road running north from Chase Hill Road between the junction with Haven Road in the east and Eastfield Road in the west.
