An energy audit of Carramar dairy farm in Womboota found significant savings could be made by renegotiating the electricity tariff for the property’s water pump, optimising the performance of its power-hungry plate cooler, recovering waste heat from the chiller and installing LEDs. Simple.
An energy audit of Skinner Partnership, a dairy operation in Dubbo, Central New South Wales, found that substantial savings could be made by upgrading pumps, installing a variable speed drive on the milk vacuum pump, and adding heat-recovery units to the dairy’s plant and vat washes.
Gundamain Feedlot has identified an opportunity to combine battery storage with solar PV to maximise the savings it makes from solar.
Approximately 40% potential energy savings were discovered from on-site generation using a combination of solar and wind. But how will the business case stack up? Monitoring and understanding energy usage provides the key.
Poultry farmers run sophisticated sheds that automatically regulate temperature, air quality and light conditions. This can require a lot of power, especially during heat spells. Solar PV systems provide great value for chicken growers, as they maximise energy savings during hot and sunny days.
Because there is no local source of water on or adjacent to the property, Garah owner and manager Bill Yates became a member of a community trust that owns and operates a large bore pump in the local area. The trust consists of 43 members, all of whom draw water from the bore. Bill is now a director of the trust. The NSW Farmers Energy Innovation program has triggered a discussion among Bill and his neighbours about what they should do after the solar feed-in tariff ends in December 2016."
Price pressures in the dairy sector are forcing dairy farmers to look for ways of cutting costs to retain reasonable margins and remain viable. “We need to increase our herd and our yield to remain in business,” says Norman McCure, owner of Binowee Dairy in New South Wales. The challenge for the McCures is to achieve improvements in yield and volume at a lower cost per litre of milk. If this challenge is met, the business could not only survive but thrive, providing sufficient motivation for taking on the additional risk and hard work that the expansion will entail. An investigation into more efficient hot water and refrigeration systems and the possibility of generating biogas on site may lead to further options for optimising Norman’s investment and delivering an estimated 30% increase in production.
The Glenwarrie Partnership near Tamworth recently invested in a state-of-the-art caged egg-laying system with packing machines and highly efficient automated feed and watering systems- however, a significant cost savings opportunity was missed...
Biomass is a fuel source that could replace diesel for farmers prepared to make the investment but the technology is not readily accessible. At Gum Creek the use of biomass is under investigation and with over $200,000 in pumping costs the incentive to innovate is strong for third generation farmer Ian Blight.
The Windella farming operation requires around 450,000 litres p.a. of diesel fuel for sowing, harvesting, trucking/transport and pumping. The farm owns five tractors, and operates four pumps (three diesel and one electric). Water for irrigation and on-farm use is taken either from a nearby river or pumped out of a bore...
