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.

The audit identified several energy efficiency opportunities including regular checks for leaks in the irrigation and compressed air systems and a lighting upgrade. The audit recommended a 10kW Solar PV system to complement energy efficiency practices already in place, to further cut power required from the grid by 35% to save over $4,000 per year with a payback of less than 5 years.

The irrigation energy audit recommended adding variable speed drives to two dam pumps as they have varying duties in supplying centre pivot irrigators. The audit also recommended upgrading 100mm steel main pipe for transfer pumping to 125mm plastic. These initiatives would result in energy savings of over $41,000 per year and a payback period of around 1.5 years.
