A prominent UK civil engineering firm, Jones Bros Civil Engineering UK, is currently constructing one of the nation’s most substantial battery energy storage systems (BESS).
The multi-million-pound contract, awarded by Quinbrook Infrastructure Partners and E.ON, is taking place at the Uskmouth site in South Wales.
Repurposing Infrastructure for Renewable Energy Storage
The 230 MW BESS is anticipated to be operational by the first quarter of 2025. This project is a cornerstone in the UK’s ambitious plan to decarbonize all sectors of its economy and achieve net-zero emissions by 2050.
It leverages the existing infrastructure of the former coal-fired power station, including grid connections, industrial water supplies, and rail access.
This strategic reuse significantly reduces the environmental impact of the project, with an estimated 230,000 miles of road transport avoided during construction.
Construction Progress and Innovative Solutions
Jones Bros has completed the initial site preparation, which included creating a compound and installing acoustic fencing.
A significant milestone was the construction of the main platform, elevated above the flood plain using approximately 74,000 cubic meters of aggregate transported by rail.
This platform is designed with four impermeable cells to effectively manage water runoff and direct it to an attenuation pond.
Current construction activities center on the foundations for the battery and power conversion system (PCS) units, as well as the primary and secondary substations and transformers.
An innovative solution involves repurposing a pre-existing fly ash tunnel to house cables and electrical components, further demonstrating the project’s commitment to resource optimization.
Environmental Enhancement and Wildlife Conservation
In line with the project’s ecological enhancement plan, which aims to establish a sustainable energy park, Jones Bros will install new fencing and conduct landscaping to create a habitat that is attractive to local wildlife such as otters and water voles.
Rhys Roberts, Jones Bros Contacts Manager, expressed enthusiasm for the project: “It’s an incredible opportunity to be part of the nation’s accelerating energy transition. Transforming a former coal-fired power station site into a key asset for renewable energy storage is a truly rewarding endeavor for our company.”
Sustainable Building Practices
The project’s commitment to sustainability extends to the construction process itself. A pre-existing garage from the old power station is being converted into a welfare building, targeting a “BREEAM Excellent” rating, a leading sustainability assessment method for buildings.
Roberts highlighted the company’s dedication to minimizing local impact: “We prioritize minimizing disruption to the local community.
Utilizing the railway for aggregate transport and the delivery of battery unit containers is a significant advantage.
Repurposing existing structures, like the garage, and striving for BREEAM excellence in its renovation exemplify our commitment to sustainable practices.”
