Cleve Hill BESS.

The challenge

Co-located BESS at Cleve Hill: 250 battery containers plus inverter stations, cooling systems and associated electrical equipment. Each structure type with its own foundation requirement, heavy concentrated loads, and a programme that had to align with the wider construction sequence.

Our approach

Helicasol manufactured and installed all helical-pile foundations for the BESS compound. Design coordinated with the project's structural engineers, load cases worked through structure type by structure type: battery containers, inverter platforms, transformer plinths and cable-routing supports.

Each pile type was specified to its actual load requirement. Larger-diameter piles with deeper embedment beneath the battery containers; lighter sections under auxiliary structures. The differentiated approach avoided unnecessary material cost while keeping every foundation inside its design load with appropriate safety margins.

Installation programme

The installation programme aligned with the broader construction sequence. BESS foundations had to complete ahead of the container delivery schedule — no room for delays. Piling teams worked systematically across the compound, completing each zone in sequence so follow-on civil works could begin immediately behind.

Compared with concrete, there was no curing time and no wet trades, and the install ran faster per foundation point.

Results

1,200+ helical piles installed on programme, enabling BESS construction to proceed without delay. Same supply chain as the adjacent electrical compound, delivered as part of one package.
