SUMMARY

The irrigation energy audit assessed a number of pumps and motors, recommending the installation of variable speed drives on each of the pumps to allow system pressure to be reduced by 100 kPa. These initiatives will reduce energy consumption by 18% with a payback of 4.2 years and carbon emission reductions of 18.7 t CO2-e per annum.

Farm profile

The farm, located in Stanthorpe, irrigates approximately 160 hectares of apple trees using a dripper system located adjacent to each tree. Irrigation varies throughout the year depending on the season and weather conditions. The farm is divided into several zones, each with its own irrigation system consisting of a dedicated pump and water storage dam. Electricity consumption is mainly for irrigation and refrigeration requirements.
