Arup and infrastructure consultancy AECOM have been appointed to deliver management of the Environmental Impact Assessment work for National Grid’s Grimsby to Walpole upgrade project.

The upgrade project is a proposal to build a new high voltage overhead line in Lincolnshire, including new pylons and substations.

The connection will deliver increased capacity along the eastern side of England comprising a new 400 kV overhead transmission line between Grimsby West and the Walpole area; in addition to new 400 kV substations to integrate offshore capacity onto the national transmission system.

The upgrade project underlines National Grid’s ongoing commitment to transforming England and Wales’ transmission network, facilitating decarbonisation of the energy system, in line with the UK government’s ambition to connect 50 gigawatts (GW) of offshore wind by 2030 – enough energy to power every home in the country.

Building on our strong relationship with AECOM and National Grid, we will help deliver decarbonisation of the energy system through projects such as Grimsby to Walpole. The transition to a zero-carbon economy and decarbonisation of the built environment for the health of our planet, is a fundamental driver for Arup. We believe the upgrade to the transmission network is key to allowing the integration of offshore renewables in reducing carbon emissions.
