This case study summarises the outcomes from audits conducted on 6 Queensland Beef Cattle farms taking part in the in the Energy Savers Program.
Energy Savers
Summary
The total energy consumption from the measured areas on the 6 farms was 192,783kWh at an annual cost of $51,293, resulting in emissions of 156 tonnes of CO2-e.
Opportunities: the main opportunities identified on the Beef and Cattle farms include
- Pumping and Irrigation- Savings from Variable Speed Drive installation, pump replacements and maintenance and changes to irrigation design.
- Heating Ventilation and Cooling (HVAC) – Maintenance and upgrades of condenser motor, VSD, ventilation fan and heating.
- Lighting and General- Replacement and retrofitting of lights with LEDs, infrastructure upgrades to facilitate efficiency gains and general management changes.
- Solar and Batteries– Grid-connected and standalone.
- Solar Systems- Ranging in size from 5-100kW.

Table 1 highlights the potential energy savings of 128,828kWh identified in the audits.
Including production benefits, a saving of $48,191 and an estimated 104 tonnes of CO2-e could be realised per annum. At a capital cost of $151,103, the average payback was 7.2 years.
Additional value adding from the energy audits showed how an increase in water delivery, could increase production and profit with a reduction in energy consumed per unit of output.

As the installation of the recommendations is made within the industry, measurement and verification will be undertaken, and case studies will be updated to include the actual energy savings.
Energy Efficiency for your Industry and Business
An energy audit is a great way for a business to cut costs, reduce emissions and boost productivity.
The audits show that there are significant opportunities in the beef and cattle industry to improve energy efficiency by implementing solar systems. A cattle farm in the Western Downs region saves $10,000 by implementing a solar pump supported by battery storage at a capital cost of $27,000, to see more details click HERE.
