St George

St George Cotton

The irrigation audit identified energy savings of 29% and a payback period of 1.3 years with a change to pump operations, installation of a variable speed drive to a 75kW pump and replacing the pump impellor with a full-size version. The audit also found up to $3,500 in savings available with a change in tariff.

Beaudesert Turf Energy

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.

Mackay Sugar Cane

The irrigation audit identified energy savings of 10% with a payback of 3.4 years by modifying the discharge piping on the 45kW pump to reduce pressure losses. Additional savings were identified by replacing pumps and adding a variable speed controlled, but with longer payback periods.

Childers Sugar Cane

The irrigation energy audit identified a number of initiative that would save over $110,000 over 10 years. These included replacing oversized pumps, and adding Variable Speed Drives where the changing elevation of the Centre Pivots caused variable head pressure. The audit also identified $600 in annual savings through tariff review.
