The emerging preferred corridor runs from the new Grimsby West substation (which the new overhead line would connect into) to a point immediately east of the village of Barnoldby le Beck (south of Waltham Road). The route taken avoids a large number of receptors and is routed such to retain distance away from the Lincolnshire Wolds AONB.

As shown in the map, the graduated swathe includes the potential locations for both the new Grimsby West substation and the overhead line. 

The substation siting area for the new Grimsby West substation is to the west of the existing substation. Our emerging preference within the substation siting area is to locate the substation within and/or adjacent to the NGET landholding to minimise impacts upon the surrounding environment and make the most use of land already in our ownership.We are expecting to route the new overhead line west of Grimsby towards Laceby, then south towards the A46. This route avoids Wybers Wood, the Grimsby West Urban Extension housing allocation, both to the east, and the Aura Power Solar Farm and existing wind turbines to the west.

Immediately east of Barnoldby le Beck, south of Waltham Road, to immediately east of the village of North Thoresby, south of the B1201.

The emerging preferred corridor runs south towards Brigsley, Due to the narrow nature of the corridor in this area, we are presenting two options for crossing the B1203, both north and south of Brigsley. Our emerging preference is to route to the north of the village to limit the overall length of the line needed and avoid the need for additional angle pylons in this section.

This section of the emerging preferred corridor runs from east of North Thoresby, south of the B1201, to a point north east of Keddington and south west of Alvingham, south of Alvingham Road.

Overall, our emerging preference in this section is to stay to the east of the corridor to increase the distance of the new overhead line from the AONB and to avoid crossing the Lincolnshire Wolds Railway.

From a point north east of Keddington and south west of Alvingham, south of Alvingham Road, to a point immediately east of Tothill.

Our emerging preference in the north of this section is to stay to the west of the corridor to avoid properties along Louth Road and a narrow area associated with properties and farms. Once south of here, the swathe takes the shortest, straightest route across the B1200, west of Manby Showground to provide greater separation from the AONB and North Reston Farm Airfield. 

East of Tothill to west of Cumberworth and includes proposed areas for the location of the two Lincolnshire Connection Substations (LCS).

The Strategic Options Report and Strategic Options Report Addendum identified that two LCS will be required to ensure necessary system resilience, to manage security risk and to ensure the most efficient solution for both the system and the community to maintain compliance with NGET SQSS. The northernmost substation is referred to as LCS A and the southernmost is referred to as LCS B. 

The siting area for LCS A covers an area north and west of Woodthorpe, east of Claythorpe and east of Greenfield Wood/Mother Wood. Our emerging preference within the substation siting area is to locate the LCS A to the south east, adjacent to Mother Wood.

The corridor for the overhead line splits in two in the northern part of this section, east and west of Greenfield Wood/ Mother Wood. The swathe shows our current preference to route east of the woodland and south of Woodthorpe Hall Golf Course. Opting for a route south of Woodthorpe Hall Golf Course reduces the overall length of new overhead line, avoids more angle pylons and maximises use of Mother Wood as a visual screen, given our emerging preference the location of LCS A.

The siting area for LCS B is located to the north of Bilsby, east of Saleby and west of Huttoft. The preferred location for LCS B substation is north of Bilsby, as shown by the swathe. Our emerging preference within the substation siting area is to locate LCS B to the east of the A1111, between Bilsby and Asserby. 

West of Cumberworth to a point east of Burgh le Marsh, south of the A158. 

The route here aims to avoid scattered properties, farms and businesses as much as possible, before crossing the A158, staying west within the corridor to avoid the underground cables for the existing Triton Knoll and proposed Outer Dowsing offshore wind farms. There is some optionality retained to potentially cross the A158 further to the east within the corridor although this is less preferable.

East of Burgh le Marsh, south of the A158, to the west of Midville, south of Fodder Dike.

Given complexity of routeing at High Lane and Croft Lane, south of Burgh le Marsh, our emerging preference is a route in the northern part of the corridor, through the Hollies Solar Park and Wind farm. This is to maintain distance from the existing 132 kV overhead line in this area to reduce impacts on residential properties.

The route then runs parallel to the Poacher railway line, crossing it north east of New Leake, before continuing south west and turning south at Midville. 

West of Midville, south of Fodder Dike, to a crossing of the River Witham between Langrick Bridge and Anton’s Gowt. In this part of the section, properties, farms and businesses are well spaced, allowing the shortest, straightest route to be taken

From Midville, the overhead line would continue south, before turning west at Hobhole Bank to Sibsey Northlands, where the route aims to avoid scattered properties. Heading south from here, our preference is to stay west within the corridor to allow for a shorter, straighter route to minimise the number of angle pylons and avoid properties along West Fen Drain.

From a crossing of the River Witham between Langrick Bridge and Anton’s Gowt to a crossing of the River Welland between Spalding and The Wash.

From the River Witham, the corridor heads directly south. At New Hammond Beck, the corridor splits in two, running to both the east and west. As shown by the swathe, our emerging preference is to route to the west of the corridor to avoid more properties in the east part of the corridor and reduce potential visual impacts.

From a crossing of the River Welland between Spalding and The Wash, to a crossing of the B1165 north west of Whaplode St Catherine. 

From the River Welland, the corridor runs south to the proposed siting area for the Weston Marsh substation. The substation siting area is located to the east of Surfleet Seas End and the River Welland, at the ‘tee’ point of the existing overhead line and the overline line connecting to Spalding power station. 

Our emerging preference within the substation siting area is to locate the substation in the centre of siting area to limit the spread of infrastructure, limit the amount of work required to the existing overhead lines, and provide increased operational flexibility.

Following this, the route continues to head south, west of Weston and east of Spalding, crossing of the A151. From here, the corridor continues east, crossing the B1165 where the corridor narrows to reduce the potential impact to the west and avoid properties to the east.

Crossing of the B1165 north west of Whaplode St Catherine to the new Walpole substation. The new Walpole substation is proposed to be located near to the existing 400 kV overhead line, north of Walton Highway.

At South Holland Main Drain, the corridor splits in two. The swathe shows our preference for the eastern route to allow for the most direct route and to minimise the number of angle pylons. Our preference within the corridor is then to continue east towards the River Nene using the northern of the three routes south west of Tydd St Giles.

Our emerging preference is to locate the substation to the south east of the siting area, adjacent to the existing 400 kV overhead line to reduce the required deviations of this overhead line and limit the spread of impacts into the surrounding environment.
