Summary

This case study summarises the outcomes from audits conducted on 5 Queensland Grains and Feedlot farms taking part in the Energy Savers Program.

Collectively the total energy consumption consumed from the measured areas on the 5 farms was 390,620kWh at an annual cost of $104,111, resulting in emissions of 359 tonnes of CO2-e. 

Opportunities:  the main opportunities identified on the Grains and Feedlot farms include

  • Pumping and Irrigation- Savings from Variable Speed Drive installation, pump replacements and maintenance and changes to irrigation design. 
  • 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.

Including production benefits, a saving of $41,109 and estimated 161 tonnes of CO2-e could be avoided per annum. At a capital cost of $261,784 the average payback was 116.8 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 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 identify the most effective way to cut costs, reduce emissions and boost productivity.  

The audits show that there are significant opportunities in the grains and feedlot industry to improve energy efficiency by implementing solar systems. A Mareeba hay farm has saved over $12,000 per year by implementing a solar pump system with a 3-years payback period, to see more detail click HERE
