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.
Interested in their options after the solar feed-in tariff ends in December 2016, the Jarretts explored the potential of investing in solar PV battery storage, electrification of its farm vehicles, a new, energy-efficient coolroom and integrated solar pumping options to reduce energy costs and help build a 'sustainable' brand image.
Gundamain Feedlot has identified an opportunity to combine battery storage with solar PV to maximise the savings it makes from solar.
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.
Many farmers would like to integrate solar power into the running of their irrigation systems; however, variable seasonal loads often make solar PV non-viable. The good news is that NSW Farmers’ Energy Innovation program has identified a solution that offsets grid power peak tariffs with on-site solar. In trialling this solution, Joe D’Anastasi of Glenorie Hydroponics has proven an ideal candidate, improving his farm’s bottom line at a time when he’s looking to expand."
The Jarretts are interested in their options after the solar feed in tariff ends in December 2016 with potential to invest in battery storage or electrification of farm vehicles to help build a sustainable brand image. Other initiatives include a review of the energy efficient design options for a new cool room as part of their business expansion and integrated solar pumping options to reduce irrigation energy costs.
Working with the NSW Farmers’ Energy Team, the Kensal Green farm in Gunnedah identified significant energy savings opportunities over the short, medium and longer term. Heading the list of opportunities was the use of variable speed drives (VSDs) on pumps, as well as proper ballasting of the farm’s new tractor.
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.
With LPG around 20 to 30 percent more expensive than natural gas and the cost of LPG expected to increase over the next few years, gas-dependent poultry farmers are looking for alternatives to LPG so as to remain competitive in a growing sector. Along with exploring alternatives to costly LPG, the owners of Stratheden Glen poultry farm are implementing or considering initiatives including a lighting upgrade that will result in significant energy savings, voltage optimisation to improve the power delivered to site, and solar power for the main pump that supplies drinking water to the chickens and water for the evaporative coolers.
