A year after construction began the 1.2MW anaerobic digestion plant at Wothersome Grange became operational in September 2015.
This alternative energy technology uses maize, grass and whole-crop wheat silage, grown on the Estate’s home farm, to produce methane gas. The gas fuels a generator, which exports electricity to the National Grid. This provides enough green electricity for about 1,500 homes.
The waste heat from the generator is being used to dry wood-chip for biomass boilers
The exhausted fuel which comes out of the digester (called digestate) is spread back onto the fields and replaces most of the fertiliser needs of the Farm. This enterprise provides a useful long-term diversification for the Bramham Park Estate.
