Additional information

The site, enclosed between a main road, railway line and a retail park, is previously developed land which was formerly used as a municipal depot and will connect to the grid via a nearby substation at Toothill. The lithium-ion batteries would be housed in containers with a 30-year lifespan for the project as a whole, and offer significant land rental value for Swindon Borough Council for the brownfield site. Public Power Solutions (PPS), established in 2010 and refocused on to sustainable energy solutions and waste treatment three years later, submitted documents on 10 November pertaining to the proposed project at the former Mannington Depot.
