How Screw Piles are Key to Enabling BESS Success in Challenging Terrains

As we continue our series RADIX Managing Partner Christian Alexander takes a look at the key advantages of screw piles for BESS foundations in challenging site conditions.

In the march towards a sustainable energy future, Battery Energy Storage Systems (BESS) are the hub of renewable integration, ensuring grid stability and unlocking the full potential of wind & solar power. As demand for these systems grows so does the challenge of finding suitable locations to site them. Traditional concrete foundation methods often struggle when faced with uneven terrain, soft soils, or environmentally sensitive areas, leaving promising sites off the menu. This is where Radix Screw Piles show their value as a versatile, efficient solution that is transforming the way BESS projects are deployed in challenging terrains.

Overcoming Barriers with Screw Piles

Faster installation means reduced labour and equipment costs, while the ability to adapt to various terrains minimises the need for expensive site preparation.

For decades, energy infrastructure projects have been constrained by site conditions. Rocky terrain, waterlogged fields, and slopes have rendered many locations impractical for development due to the cost and complexity of traditional foundations like concrete or driven piles, but with the advent of screw piles, these limitations are no longer a barrier.

Screw Piles are tubular steel sections that are drilled directly into the ground to varying depths depending on soil conditions, providing robust, stable foundations without the need for excavation or heavy machinery. This approach minimises site disturbance, making it an ideal choice for regions with strict environmental regulations. In challenging soil conditions—where traditional methods require extensive preparation or reinforcement—screw piles excel, offering a faster, more adaptable alternative.

Expanding the Geographic Reach of BESS


The flexibility of screw piles and ground screws is enabling the deployment of BESS projects in areas previously deemed unsuitable. From waterlogged fields in rural landscapes to rocky highlands, these systems are opening opportunities to bring renewable energy storage to regions with diverse and complex topographies.

RADIX has seen first-hand how ground screws make it possible to install foundations on soft, uneven soils without the need for costly remediation. By skipping the excavation and curing times associated with concrete, projects can be completed faster, helping developers meet tight deadlines and deliver critical energy storage capacity to the grid.

Environmental & Economic Advantages


The environmental benefits of screw piling and ground screws extend beyond reduced site disturbance. By eliminating the need for concrete, a material with a high carbon footprint, ground screws help BESS developers reduce the overall emissions of their projects. This of course aligns with the broader goals of the renewable energy sector, ensuring that clean energy solutions don’t come at the expense of the environment.

Economically, ground screws also offer significant cost savings. Faster installation means reduced labour and equipment costs, while the ability to adapt to various terrains minimises the need for expensive site preparation. This makes BESS projects more viable in remote or challenging locations, ultimately accelerating the transition to a renewable-powered future.

The RADIX Perspective

At RADIX, we believe that screw piles are more than just a foundation solution—they’re enablers of innovation and progress in the renewable energy space. By expanding the geographic reach of BESS deployment, screw piles are helping to overcome some of the most significant barriers to clean energy adoption. Whether it’s stabilising a solar array on soft ground or supporting a transformer in waterlogged terrain, our screw pile solutions are paving the way for a more sustainable and resilient energy grid.

As the demand for renewable energy grows, so too will the need for innovative, adaptable solutions to support its infrastructure. Radix Screw Piles represent a critical piece of the puzzle, ensuring that no matter the terrain, clean energy can thrive.
