Onshore proposals
Landfall
The Extensions Project is planned to be connected onshore at the Muckleburgh Estate, to the west of the Weybourne Beach car park. Weybourne Beach will remain accessible throughout construction. The landfall compound has been positioned and reduced in size to minimise impacts to the surrounding habitat. We have also identified vehicle access routes and space for cable duct preparation that makes use of existing access tracks within the Muckleburgh Estate. This allows us to avoid public roads in this area, minimising any potential disruption to accessing Weybourne Beach.
Cable Route
The cable route will be approximately 60 km long from landfall in Weybourne to the onshore substation close to the existing National Grid Norwich Main substation near Swardeston.
The installation of the onshore cable is expected to take up to 24 months, provided that the projects are developed concurrently. The onshore cable route will be installed in sections of up to 1 km at a time, with a typical construction presence of up to four weeks along each 1 km section. Following this, the land will be reinstated and can return to its previous use.
Onshore Substation
A new onshore substation will be constructed to accommodate both of the Extension Projects. This will be located adjacent to National Grid’s existing Norwich Main Substation just south of Norwich, close to Swardeston. The substation will not be visible from any nearby properties, given that it is at least 500 metres from the nearest residence as well as benefiting from existing screening.
To minimise impacts to traffic, access to the substation during both construction and operation will be via the A140. Access will not be taken via the B1113. This decision was made as a result of stakeholder feedback.
