Summary

This case study summarises the outcomes from audits conducted on 2 Queensland Piggeries taking part in the Energy Savers Program.

Collectively the total energy consumption consumed from the measured areas on the piggeries was 458,344kWh at an annual cost of $103,203, resulting in emissions of 421 tonnes of CO2-e per annum. 

Opportunities:  the main opportunities identified at the Piggeries include

  • Pumping and Irrigation- Savings from Variable Speed Drive installation, pump replacements and maintenance. Changes to irrigation design and automation. 
  • Heating Ventilation and Cooling (HVAC)– Condensor motor, VSD, ventilation fan and heating upgrades.  
  • Lighting and General- Replacement and retrofitting of lights with LEDs, infrastructure upgrades to facilitate efficiency gains and general management changes. 
  • Gas- Hot water, insulation and general heating improvements to gas systems on farm. 
  • Solar and Batteries– Grid connected and standalone. 
  • Solar Systems- Ranging in size from 5-100kW.

Table 1 highlights that total energy savings of 486,617kWh were discovered from the audit process.

 Including production benefits, a saving of $86,464 and estimated 448 tonnes of CO2-e could be realised per annum. At a capital cost of $300,195 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 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 pork industry to improve energy efficiency by investigating the gas systemsA piggery farm in the Southern Downs region saves over $70,000 per year by upgrading the lighting and ventilation systems, as well as by implementing solar systems, with a total capital cost less than the savings, to see more details click HERE
