Seabank substation and nearby pylons at Crooks Marsh

National Grid is working with Western Power Distribution (WPD) to make changes to Seabank substation, and to replace nearby pylons at Crooks Marsh with new underground cables.

Our contractor for this work, J Murphy and Sons, completed the first task of building a construction access and layby on Ableton Lane in April 2022.

With the new access complete, work is underway to build the construction road needed to access our work areas and prepare the land at Crooks Marsh for installing new underground cables. The underground cables will replace existing WPD lattice pylons in the area.

As Ableton Lane is narrow in some parts, two-way traffic lights will be in place to manage construction traffic until the Hinkley Connection works are completed in late 2023.
