Vattenfall Maps Norfolk Onshore Infrastructure Locations

Vattenfall, the developer of the Norfolk Vanguard and Norfolk Boreas offshore wind farms, has published maps showing a reduced number of search areas identified as potential locations for onshore electrical infrastructure. 

“Thanks to feedback from communities in Norfolk and environmental specialists we have been able to further refine search areas for the onshore electrical infrastructure,” Ruari Lean, Vattenfall’s Project Manager for Norfolk Vanguard, said.

”I would like to thank everyone we have spoken to for their contributions and patience as we carefully move towards the selection of final locations. The search areas have been chosen because we believe they offer the best opportunity to minimise impact – not least our early decision to lay underground the 60km transmission cables.”

The maps show that landfall for the transmission cable running from the wind farms will be south of Happisburgh as it avoids a Marine Conservation Zone and there is enough space at the landfall to accommodate the transmission cables from both projects.

The two search areas for cable relay stations (CRS), if Vattenfall opts for High Voltage AC (HVAC) cables, are west of Happisburgh, for co-location of onshore infrastructure. The sites enable relative seclusion, co-location of both, good access, and opportunities to minimise visual impact through topography and screening, the company said.

A search area for a substation is to the north east of Necton village and to the east of existing infrastructure.

The 60km underground cable route search area from landfall to Necton shows local refinements.

The 1.8GW Norfolk Vanguard and the 1.8GW Norfolk Boreas will deliver on average enough fossil-fuel free electricity every year to meet the needs of almost 50% of the East of England.

“The infrastructure is needed to put Norfolk Vanguard’s and Norfolk Boreas’s fossil-fuel free, home grown electricity onto the National Grid. Getting the go ahead will trigger significant jobs opportunities in Norfolk and support action on climate change,” Ruari said.

Vattenfall will continue to engage with stakeholders and residents throughout the summer. In the autumn the energy company will hold drop-in sessions which will show Norfolk Vanguard’s final proposed design – on and offshore – and the assessment by independent specialists of its environmental impact.
