On UK Farms there is more than enough manure to meet heat demand. The below chart compares the heat demand for minimum ventilation (red) to the heat required to optimise conditions for bird welfare (green). Even when meeting this increased demand for heat there is manure left over.
A Combined Heat and Power (CHP) will generate electricity throughout the flock to ensure all the manure created of a farm may be used to meet energy needs (green line). Approximately half the electricity demand on the site can be met using this system, and 90% of the sites heat demand.
Every site is different and BHSL build a custom energy model for each site when designing the solution. Warmer climates will have lower heat demands leaving more heat available for generating electricity.
