Housing MRO operations, defence engineering, and advanced manufacturing, the Park has large building footprints with consistent high daytime electricity consumption — exactly the load profile that maximises solar self-consumption and ROI. Systems of 250kW–1MW are technically feasible across several buildings at St Athan, and the Park's planning regime supports Permitted Development for rooftop solar on most structures.
