North West Coast Connection for National Grid


National Grid


400KV Grid Connection

Details & Location

Lake District National Park

This 400kV grid connection to the Moorside Nuclear Power Station would have included overhead line, underground cable, subsea tunnel, new substations and associated temporary construction infrastructure (compounds, access tracks, temporary and permanent lower voltage diversions) within and in close proximity to multiple national and European level designations.

Stephenson Halliday led the landscape and visual effect assessments for the proposals in some of the most sensitive sections of route alignment within the Lake District National Park and immediate surrounds.

The work included:

  • Baseline studies. Completed in accordance with relevant scoping findings for the area within which the potential effects of the proposals may be felt. Particular sensitivities arose from the study area being within and adjacent to the Lake District National Park (and now World Heritage Site).
  • Routeing, Siting & Alternative Option Studies. LVIA topic contributions to studies to locate elements of infrastructure including route alignments, substations, site compounds and both temporary and permanent 132kV OHL diversions. Option appraisals of 400kV overhead line connections (including T-pylon and low height options) and underground cable alternatives including sites for Cable Sealing End Infrastructure.
  • Landscape & Visual Effects chapters for Scoping, PEIR and ES. Written reports capturing baseline, potential effects, mitigation and Impacts of the proposals for Scoping stages (2015), PEIR (submitted late 2016) and draft ES prior to project halt.
  • Stakeholder & Consultee Liaison. Meeting attendance to present and discuss landscape and visual effect issues with consultees and other non-statutory stakeholders including at public consultation events, project wide regular stakeholder meetings and topic specific stakeholder meetings.

One of our Technical Directors had a key role in the design refinement of the project, holding a role at the centre of the interface between engineering design and environmental topic teams as the design was developed in response to consultation feedback and cost review.

As testament to their effectiveness we would note that very senior staff in NG commented that as a result of their role liaising between teams “.. the relationship between consents, engineering and consultant staff had never been better”.
