Q&A's for BESS
If you have a question about our foundation solutions and the answer is not here, please contact us directly, and we’ll be happy to help you.
What is BESS in renewable energy?
BESS stands for Battery Energy Storage Systems.
These are systems of one or more battery units that store energy from different sources and then discharge it when required. These battery storage systems consist of rechargeable batteries that are intended to back up the grid and supply energy when reserves are low, thus improving the stability of the grid and hopefully avoiding power outages. BESS is typically associated with storing energy from renewable energy sources like solar or wind.
Is the load-bearing capacity of a screw pile suitable for a BESS project?
Yes. Load-bearing capacities will depend on the ground conditions and the depth screw piling will achieve, but we can safely achieve installation of screw piles for BESS developments up to 10m and achieving 130kN per screw pile.
We have, for example, installed our screw foundations to depths exceeding 16m and achieved a load-bearing capacity of 200kN per screw pile. Our hybrid helical screw pile system will be capable of providing not only strong and secure foundations, but add to the sustainability factor of what a BESS project is based upon.
For BESS projects, what size of piling mat is required for installing screw pile foundations?
We do not require the heavier-duty installation equipment to install our screw foundations, which in turn reduces the thickness of the piling mat required, and the associated costs and time to build a large piling mat. With no need to remove spoils or bring materials to site, vehicle movements are reduced by approximately 66%.
Can screw piling reduce BESS project costs, as there is no soil removal?
Yes! Screw piles altogether avoid the need for heavy excavations, meaning no spoils need to be removed from site, saving additional time and lowering project costs.
How are screw piles installed on battery energy storage system projects?
We deploy our hydraulic installation machines on BESS projects, either in a mix of our all-in-one crawler rigs, or hydraulic drives to provide greater torque on installations. Our installation process allows smaller machinery, with lower costs, to access difficult locations and rapidly install the foundations, which leads to your BESS project being ready on time and within budget. Hit your milestones and energise your project faster with our dynamic foundation solutions!
Can helical screw piles help a BESS project on challenging ground?
Utilising our agile and powerful installation equipment, our screw foundation solutions can overcome challenging site locations and tough ground conditions, accessing built-up urban or off-grid areas and overcoming areas of soft and waterlogged ground. With our extendable screws, we can reach the load-bearing ground required to support your BESS modules.
Are screw piles the only type of foundation used in BESS projects?
Sadly no, as some projects still go ahead building on concrete as a foundation solution, which is ironic considering battery energy storage systems are part of a chain aimed at increasing the use of renewable, cleaner energy, and concrete (cement) is one of the largest contributors to carbon emissions.
If you want to make a difference, start demanding for alternative foundation solution to concrete, like our screw piles… they are better in many ways!

What is the difference between a battery and a BESS?
A BESS stores the energy using battery storage technology. Energy is typically collected from green energy sources like wind or solar panels, in addition to the electricity network. When power is required, the batteries will release energy to balance the grid, supplement peaks and restore power from outages.
How do BESS work?
A battery storage system collects energy from various sources, typically renewable sources like solar and wind, and stores it in the batteries in order to release it when it is needed.
What are the benefits of BESS?
Innovative Energy Storage: Empowers sustainable energy management by storing surplus power during low-demand periods and discharging it during peak demand, minimising the necessity for additional generation and fostering a balanced grid.
Grid Stability Reinforcement: Ensures grid stability, allowing for smoother power flow and reducing blackouts, thus promoting a more dependable energy supply.
Seamless Renewable Integration: Capitalising on excess energy generated from renewable sources like wind and solar, BESS enhances the seamless integration of these intermittent energy solutions into the grid.
Peak Shaving and Cost Savings: Businesses can utilise BESS to lower peak energy consumption, yielding considerable cost savings by avoiding high-demand charges.
Reliable Backup Power: Guarantees a fail-safe source of backup power during outages, safeguarding continued operations for mission-critical facilities.
Energy Cost Reduction: By leveraging stored energy during peak hours and buying electricity during off-peak times, BESS contributes to lowering energy expenses.
Eco-friendly Benefits: Decreases greenhouse gas emissions by maximising utilisation of clean energy sources, reducing dependence on fossil fuel-based power plants.
Dynamic Demand Response: With its ability to rapidly adapt to demand or supply fluctuations, BESS serves as an invaluable asset for demand response programs and grid management.
To summarise, BESS is a vital element in optimising energy usage and fortifying grid stability reliability, and promoting the integration of renewable energy sources, making them a valuable asset in the energy market.
