Washfold Biogas

Deal Overview

Washfold Biogas is a joint venture company between Iona and a family run farm near Leyburn, North Yorkshire. The plant has been designed and built by Anaergia and Surgo Construction at Metcalfe Farm’s site. The farm supplies the feedstock from existing farm wastes such as manure and slurry. The plant generates 200kW of renewable electricity from the anaerobic digestion process, receiving income under the Feed in Tariff Scheme, with the electricity being used on the farm or sold to the National Grid.  The farm has the benefit of free heat from the plant and the use of the digestate bi-product on the land as a bio-fertiliser. 


The plant is operated by Advantage Biogas Limited (“Advantage”). Advantage provides support services to Biogas plants in the UK focusing on routine maintenance, health and safety reports, plant optimisation and biological services.
