The farm, near Tolga in North Queensland, comprises five broiler meat chicken sheds with 6,900m2 of usable floor area that house approximately 188,000 birds. The main energy consumption is driven by climate and temperature control systems, as well as water supply, food supply and lighting, with an annual energy consumption of approximately 280,000 kWh at a cost of $82,000.
An energy audit showed how improving the current systems can lead to energy and cost savings by investing $58,000, the recommendation explored in the audit included:
- Replace 40 cross flow ventilation fans with more efficient units.
- Install a 10 kW solar PV system to offset the base load consumption during the day.
Table 1. Energy savings from audit recommendations
| Recommendation | Energy savings (kWh) | Cost Savings ($) | Emission Savings (tCO2-e) | Payback Period (Years) | Cost to Implement ($) |
| Ventilation upgrades | 36,500 | 10,000 | 30 | 4 | 40,000 |
| Solar PV system | 18,700 | 5,500 | 15 | 3.3 | 18,000 |
| Total | 55,200 | 15,500 | 45 | 3.8 | 58,000 |
By installing the recommendations in the audit, the business could reduce energy consumption by 20%, and costs by 19%, with carbon emission savings of 45 tCO2–e per year. Cost savings include reductions in maintenance costs given more efficient ventilation units.
Table 2. Pre and post audit energy consumption and costs.
| Audit Metric | Pre-Audit | Post-Audit | Reduction (%) |
| Energy Consumption (kWh) | 280,000 | 224,800 | 20 |
| Cost ($) | 82,000 | 66,500 | 19 |
Additionally, it was recommended to evaluate biogas generation opportunities every year, comparing market pricing against capital investment, until become economically viable.
An energy audit is a good investment
An energy audit is a great first step in moving a business towards a more efficient future by reducing energy use, costs and Carbon emissions onsite.
The Energy Savers Plus Extension Program was delivered in by the Queensland Farmers' Federation with support and funding from the Queensland Department of Energy and Public Works.
