Renewable Energy

The farm has recently built an anaerobic digestion (AD) plant, in a joint venture with an AD and farming business from Gloucestershire. This is fuelled using food waste, collected from a 100 mile radius of Codford. The plant takes 75,000t of waste and coverts it into 3.7mw of electricity, (enough for 3,700 homes or 11,000 people), which is sold into the grid. The farm will take the digestate (the inert, digested waste) from the AD, which will be stored in lagoons and spread as a fertiliser onto our growing arable crops and dairy pastures.
We are finding new uses for the spare heat generated by our CHPs, with a 3ha (8 acre) glass house planned for horticultural use which will be powered by spare heat, carbon dioxide, and electricity from the AD. We have also installed one of the first ORC units in the UK – this uses exhaust gas heat to generate a further 150kw of renewable electricity.

During 2013 we developed a 10 hectare (25 acre) field of photo voltaic panels. This can produce up to 6.5mw of power. The site is screened from view by existing woodland, and by a wild flower rich chalk screening bund.
In February 2016 we added a further 8 ha (20 acres) that can produce 5mw, situated next to the original field.
In February 2012 we installed 2 roof mounted PV arrays on our farm buildings. Our main dairy building has a 30kw array which supplies around 50% of the dairy’s power requirements, with the balanced exported to the grid. Our grain store has a 50kw array which supplies around 15% of the power requirements for that grain store.
In January 2013 we installed a 100kw woodchip boiler into the buildings complex at Manor Farm, Stockton. This provides heat to all the buildings in the area, including two houses. It runs on chip that is sourced from our forestry, which is processed and stored by our farming neighbour.
