Widow Hill BESS - Burnley, Lancashire.
We recently completed a substantial package of civil engineering and HV cable installation works for the new energy development at Widow Hill in Burnley for our client Suir Engineering.
Our scope included earthworks and ground formation, construction of more than 40 reinforced-concrete equipment foundations, and installation of a central cable route formed from large precast-concrete troughs and associated ducting. Working closely with the specialist earthing contractor, our teams completed the backfilling and compaction of the compound before forming the final site levels ready for the external security fencing.
A key part of the project was the installation of the cable duct route between the site and the nearest electricity pylon. This required careful planning and close coordination with Electricity North West and several external stakeholders. Once the infrastructure was complete, our team installed and tested the 132KV HV cables ready for final connection and commissioning.
We also constructed the new DNO building, including extensive foundation slabs, large cast in-situ cable trenches and multiple external cable entry points. The building was completed with a brickwork facade and coated timber roof structure, together with the associated internal wall, floor and ceiling finishes.
The project brought together earthworks, reinforced concrete, drainage, ducting, cable installation, building works and specialist electrical interfaces within one coordinated delivery programme. A great example of the integrated civil engineering and energy infrastructure capability we can provide - from initial site formation through to cables ready for connection.
