Condamine Feedlot

The audit made many recommendations such as a boiler economiser and boiler combustion oxygen levels, voltage optimisation and adjusting feed processing to avoid some heating elements. A number of recommendations had a total annual energy cost saving of over $77,000 with a payback period under the companies’ 3 year payback target. Around $72,000 of extra annual savings may be available through a tariff change.
