A farm producing fodder feed for livestock has the potential to reduce energy consumption and costs by installing new efficient pumps and making changes to the irrigation system.
A Mareeba farm that produces hay has the potential to save time and money after implementing a solar PV system on an upgraded automated pump supplying water to a centre pivot.
An Atherton tablelands hay farm has the potential to save time and money after implementing a solar PV system on an upgraded automated pump supplying water to a centre pivot.
The Audit recommended a number of steps to improve the efficiency of three bore pumps along with solar systems to reduce the farms power consumption by over 60%. This case study compares Solar PV options for each of the three pumps.
The Audit recommended a number of small projects with quick payback as well as upgrading lighting and installing solar and batteries to reduce grid power by 78 per cent.
This case study compares the costs and benefits of a powering a small pump with a grid connected solar system, or taking the pump off-grid with solar and a battery.
A Mareeba banana farm is on track to save 45% off their power bill for one of their pump stations with a new variable speed drive and a tariff change recommended in the Energy Savers audit. They are also getting more even watering and expect to cut maintenance costs!
An energy audit recommended replacing a 75kW pump with a 45kW pump and Variable Speed Control. Also, eliminating some right angle bends from the pipes at an adjacent 4kW pump will allow it to deliver 1kL of extra water per hour.
Lower Burdekin Water Board cut their power consumption by 58,000kWh and demand by 105kVA resulting in annual cost savings of $20,000 or 25% at the Kilrie Gully pump station.
