Construction of the 230 MW Uskmouth BESS
Overview of the Project
The construction of a 230MW battery in Uskmouth ”Uskmouth BESS“, South Wales, has begun, according to civil engineering firm Jones Bros. One of the biggest battery storage projects in the UK to date is the battery energy storage system (BESS), for which Quinbrook Infrastructure Partners and E.ON have awarded the company a multi-million-pound contract. Anticipated to commence operations in the initial quarter of 2025, the 230MW battery is poised to play a pivotal role in attaining the nation’s net zero objectives of decarbonizing all economic sectors by 2050.
Construction Progress and Sustainability Efforts
The Jones Bros team has been constructing the main platform since finishing the enabling works at the location of a former coal-fired power station. These tasks included building the compound and putting up acoustic fencing. To make sure the aggregate was above the flood plain, about 74,000 cubic meters were transported by rail. Four impermeable cells on the platform aid in collecting water and distributing it to an attenuation pond.

Right now, the primary and secondary substations, transformers, and the foundations for the battery and power conversion systems units are the main areas of activity. Before any ducting is done, a fly ash tunnel that is a part of the current infrastructure will be cleared out and used to house cables and electrical components.
In order to attract wildlife like otters and water voles, new fencing and landscaping will be done as part of the ecological enhancement plan, which also includes building a sustainable energy park. A 230,000 mile decrease in road travel is anticipated during the construction phase, and the team is working towards achieving an excellent Building Research Establishment Environmental Assessment Method rating by converting an existing garage from the former power station into a welfare building.
Significance of the Project
As the nation’s energy transition picks up speed, Jones Bros contacts manager Rhys Roberts, who leads a 20-person team that includes two apprentices, remarked, “It is a fantastic scheme to be a part of.” He added, “It is fantastic for us as a company to be able to assist in transforming a former coal-fired power plant site into one that will significantly support renewable energy sources.”
