Burdekin Sugar Cane

A range of initiatives were identified including replacing some pumps and motors with new pumps and variable speed drives, with a payback period of 2.8 years and annual cost savings of around $16,500. An extra $10,000 annual saving is potentially available at the site by reviewing the tariffs of the pump stations.

Bowen Mango & Tomato Farm

The audit identified a range of energy saving initiaves in the packing sheds including refrigeration, lighting and the installation of Solar PV to supply some power. Three projects had a payback less than 5 years including the lighting and two Solar PV installations. The estimated annual savings from all identified projects is nearly $50,000.

The Audits of several meat processors identified the potential benefits of adding variable speed controls to evaporator fans with temperature control logic allowing the fans to operate at a lower speed with significant electricity savings. The audits have identified some quick wins to reduce costs of refrigeration systems at low cost.
