This case study summarises the outcomes from audits conducted on 10 Queensland turf, sheep and pasture farms taking part in the Energy Savers Program.
This case study summarises the outcomes from audits conducted on 10 Queensland turf, sheep and pasture farms taking part in the Energy Savers Program.
The total energy consumption from the measured areas on the 10 farms was 699,019kWh, at an annual cost of $185,317, resulting in emissions of 566 tonnes of CO2-e.
Opportunities: the main opportunities identified on these other farms include

Table 1 highlights the potential energy savings of 252,852kWh identified in the audits.
Including production and potential tariff savings a reduction of $143,419 and an estimated 205 tonnes of CO2-e could be avoided per annum. At a capital cost of $506,610, the average payback was roughly 5.1 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 grains and fodder 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.
