The irrigation energy audit assessed a number of irrigation systems, and recommended the addition of variable speed drives to an existing pumping station consisting of 2 x 7kW and 1 x 5.5kW fixed pumps. The upgrade would result in energy savings of 1% on total energy consumption, corresponding to 15% savings of energy use for irrigation, with a payback of 11 years and with carbon emission reductions of 1.4 t CO2-e per annum.
