Summary

Of the energy-saving opportunities evaluated, two initiatives were identified with potential energy savings of 19%, a payback period of 2.8 years, and carbon emission savings of 20.9 tCO2-e per year. The energy audit recommended the upgrade of Pump 2 to a high-efficiency model with the installation of a variable speed drive (VSD) to ensure the pump operates closer to the best efficiency point under its various duty loads.

Farm Profile

The farm, near Mareeba, produces sugar cane and is in the process of transitioning to coffee production. A combination of pivot boom traveling irrigators and trickle tape, with a small area using fixed sprinklers, irrigates the 92-hectare farm. The irrigation water supply is pumped from a 10 Ml dam on the property that relies on a combination of natural water ingress as well as the Tinaroo water scheme.
