In an era of energy transition, renewable technologies are more accessible. To phase out fossil fuels, more energy storage infrastructure must be developed. As the most mature energy storage technology, pumped hydro storage provides opportunities to design landscapes as batteries.

Battery Landscape suggests a landscape architectural approach from site selection to landscape design, prioritising social suitability and ecological potential. Seeing battery landscapes as catalysts for regeneration, Ffos-Y-Fran in South Wales is used to explore the potential for transforming the post-extraction coalmining site into a green energy infrastructure, promoting transition amid phasing out polluting industries. The hydrological system of the site, which is core to the operation of Battery Landscape, is designed to create a nature-oriented infrastructure to collect, divert and remediate runoff for the generation of electricity.

Battery Landscape aims at not only developing a topographically sensitive energy landscape, but also providing chances for communities to reclaim post-extraction common land in the process of revegetating Ffos-Y-Fran and creating habitats for wildlife.
