BESS: 50MW Battery Energy Storage System on Screw Foundations, England
RADIX Extendable Screw Piles are providing efficient and robust screw pile foundations for this 50MW BESS project in Maldon, helping cut the programme delivery time by 60%.
Overview
BESS Development Project
A short programme to support tonnes of PCS units
We were asked by G2 Energy to provide a specialist foundation solution for a 50MW Battery Energy Storage System (BESS) project supporting 18 battery units, 5 inverters, and 11 PCS units at a site in Maldon.
PCS units have traditionally been installed on individual concrete pads that are piled to make them stable before pouring the concrete. A timely and expensive process.
A short programme of work was required to meet the project’s schedule and delivery, installation, and connection for each of the three 6m and eight 12m PCS units.
Solution
Deliver an efficient and robust foundation solution, cutting programme times by 60%
Working with the project’s engineers, we completed a site survey, load tests, and structural calculations using technical data from testing to ensure the correct specification of screw pile foundations.
Over 200 RADIX Extendable 76mm Screw Piles were installed to securely anchor the bespoke galvanised structural steel platforms designed, manufactured, and installed, with each 12m platform holding up to 10 tonnes of equipment.
Screw pile extensions sit 500mm above the ground to allow an elevated point of access for rapid installation and connection of each PCS unit and cabling, as well as provide a natural cooling solution and help protect against any potential flooding risk.
With the ability to be installed throughout the UK’s changeable weather conditions without compromising foundations’ integrity or waiting on concrete curing, RADIX Screw Piles can be built on immediately, significantly reducing programme times.
Delivered in a turnkey solution, both screw piles and bespoke platforms were installed and ready to be built on without delay. The project was completed in seven days thanks to our highly experienced screw piling team, cutting the programme length by 60% compared to concrete.
RADIX Screw Piles have allowed us to cut clients’ programme lengths by 60% in most cases and more in others, also avoiding costly delays due to temperamental weather conditions. It is clear that the industry recognises the significant impact using screw piles can have on their project delivery times and consequently how quickly they can start to see a return on their investment. We’re excited to be growing so quickly in the UK, and be expanding into new markets overseas.
