Summary

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 and greenhouse gas emission reductions of 40.1 t CO2-e.  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. 

Farm Profile

The nursery located in Karalee in southern Queensland produces mainly gerberas and roses and occupies an area of 1.9 hectares. Hydroponic cultivation and heating of greenhouses enables plants to flourish all year round. Operations on site also include packaging of flowers and storage in cold rooms until their delivery to customers. Water is drawn from the Brisbane River and treated on site via a flocculation and reverse osmosis system before it is used for irrigation. The irrigation system consists of pressure compensating drippers at each plant.
