Walney Substation

Project Overview
With the ability to power over 590,000 UK homes from a total capacity of 660 mw, Walney Extension is set to be the biggest offshore wind farm in the world when it is commissioned at the end of 2018.
The project is 100% owned by Ørsted and required a new cable corridor to be installed to its Electrical Substation near Heysham.
The new onshore Substation covers an area of reclaimed marshland and required an innovative perimeter and internal fencing package to be designed to offer the highest levels of security and electrical safety. Design work started in 2017 and looked at how existing fencing systems could be used to create a bespoke solution.
The project was installed as part of a Joint Venture with Lowther Forestry Group, a member of CLD Approved Contractor Scheme (ACS) network member who was involved throughout the entire process and their work is a testament to the success of the project.

The Brief
Protecting Critical National Infrastructure in the Utilities Industry presents a number of challenges that had to be overcome.
- External Perimeter to offer guaranteed delay against attack
- All fencing to be earthed or offer non conductive features
- Internal Fencing to include multiple systems including Rigid Mesh and GRP in same fence line
- External Perimeter and Physical Access Control to be compatible with power fencing (electric fencing) to meet security requirements
- Internal Fencing to be base plated
Systems Used

CLD Systems went the extra mile with us on this project. The whole package was well received by the end client. It shows how Manufacturers and Fencing Contractors can work together to share ideas and innovations.
