SUMMARY

This irrigation energy audit recommended replacing two in-line centrifugal pumps with a single irrigation pump and Variable Speed Drive with energy savings of 34%. A 5kW solar system providing 39% of the sites energy was also evaluated, with carbon emission reductions of 5.2 t CO2-e per annum.

Farm Profile

The farm in Bundaberg grows continental cucumbers in three greenhouses covering 1.3 hectares. The site is divided into a number of zones with the operation of the irrigation system dependent on the age of the plants, the season and weather conditions. Cucumbers are packed and stored in cold rooms at the farm before distribution. The packaging and cold room are within the existing farm shed along with a small workshop.

Farmer feedback
Recent feedback from the farm owner indicates that, following planned farm crop diversification, the payback periods will be recalculated to reflect updated running hours with a view to implementing the energy conservation measures.
