Renewable Power Capital (RPC) and Greenfield have received planning permission for a 49.9 MW battery energy storage system (BESS) in the Vale of Glamorgan, near Cardiff, Wales. This project marks the third collaboration between the two companies, following the approval of two previous projects in Steventon and Tredington in 2024. Collectively, these projects will contribute a total capacity of 112.7 MW.
Construction of the Cardiff BESS is projected to take between six to twelve months, with the facility expected to connect to the distribution network by 2030. The energy storage system is designed to enhance grid reliability by supplying power when renewable sources like wind and solar are not generating electricity, thereby supporting the UK government’s goal of decarbonizing the electricity grid by 2030.
In addition to energy storage, the Cardiff project includes initiatives aimed at improving local biodiversity. The development plans include enhancing existing hedgerows and establishing 4,560 square meters of new species-rich grassland. These efforts are intended to foster a diverse ecosystem, promoting a variety of plant and animal species in the area.
Since forming their partnership in May 2023, RPC has expanded its battery storage pipeline to over 5.5 GW across Great Britain, Italy, and Finland. Cyrille Sokpor, Senior Vice President for UK and Poland Development at RPC, expressed satisfaction with the latest approval, stating, “We’re delighted to receive planning permission for yet another UK BESS project that will make a timely contribution to the Government’s goal of decarbonising the electricity system by 2030.”
David Ring, Managing Director for the UK at Greenfield, noted that obtaining planning permission for Cardiff represents a vital advancement for their collaboration with RPC. He highlighted the dual benefit of the project, which not only aims to bolster grid stability but also aligns with their commitment to biodiversity and environmental stewardship.
Overall, this project exemplifies how advancements in battery storage technology are crucial for a balanced and sustainable energy future.
