View project
Works were carried out to demolish an existing storage building, and replace it with a larger, modern structure.
Cathkin BESS
The site was a greenfield location where a new 33kV metering substation was installed to facilitate this connection.
The Project
The site was a greenfield location where a new 33kV metering substation was installed to facilitate this connection. Adjacent to this area, an existing BESS substation served as the point of connection for the new BESS facility.
Located approximately 3km north of central East Kilbride, the site was in a rural area primarily surrounded by arable land. Within a 1km radius, there was a nature reserve and several farms.
Story was responsible for the civil and structural elements of the Cathkin BESS Project and operated as a subcontractor under Ethical Power. As this was some of the team’s first involvement in a BESS project, we adopted proactive approach to navigating unfamiliar interfaces. The challenge was further compounded by the design arriving in a non-sequential order, but we successfully adapted by maintaining close collaboration with other subcontractors.
To enhance efficiency, we conducted live lessons learned sessions with the team at another live BESS site in Broxburn, allowing us to identify and address any issues or inefficiencies they encountered—ensuring we did not face the same challenges. Similarly to Broxburn the overall construction process was relatively straightforward.

The Scope
The scope of the project was to implement the following works:
• Comprehensive earthworks to prepare the site were undertaken.
• Construction of site access roads.
• Implementation of security measures and lighting systems.
• Installation of precast battery container & BIC foundations.
• Construction of additional foundations around thee MV skid perimeter.
• Installation of effective substation drainage works and underground ducting routes.
Value Engineering
The team were able to re-use timber formwork panels from the Broxburn BESS project and utilised the same supply chain.
The Story Way
The Cathkin BESS team hosted a Construction Aware Industry Taster Day, as part of Story’s commitment to inspiring future generations. The ten pupils involved were all interested in careers in construction and thoroughly enjoyed learning about the various roles open to them. The group took part in a live site visit with our Graduate Engineer, interactive STEM session as well as a bridge building competition where the winners were judged on design, cost and teamwork.
