Mareeba Banana Farm

Mareeba

Mareeba Banana Farm

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!

Tablelands Irrigation Farm

Tablelands

Tablelands Irrigation Farm

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.

Karalee

Karalee Flower Farm

Karalee

Karalee Flower Farm

The farm has implemented a lighting upgrade, Power Factor Correction (PFC) and a 30.4kW Solar PV system to achieve annual energy savings over $14,700. The lights and PFC offer a payback period of under 3 years, with the PV payback around 5½ years. The Pump VSD and pressure transducer once implemented will allow the pump to operate at its Best Efficiency Point.

Brookstead

Brookstead Cotton Farm

Brookstead

Brookstead Cotton Farm

Two stages were removed from a seven-stage pump which reduced the flow rate but improved the combined efficiency by 25%. The pump demand has been reduced by 12kW and even with increased running time, running costs have reduced by $1,200 per year with a payback period under two years.

Cecil Plains

Cecil Plains Cotton Farm

The Audit recommended a new, smaller pump which increased water flow by 1.1ML/day and improved combined efficiency by nearly 30%. The pump upgrade has been completed by the farmer even though the payback period on energy cost savings alone was estimated at over 9 years.
