"New Zealand's dairy farms could achieve cost-effective annual energy savings of at least 68.4 million kilowatt hours (kWh) in the dairy shed, according to the results of a pilot programme. That's a 10% reduction and is equivalent to the annual electricity use of around 7100 households. Individual farms could cut milking shed electricity consumption by 16% and a post-pilot survey shows 46% of farmers will adopt savings technologies if their costs can be recouped within three years"

"Water heating accounted for 24% of consumption, water pumping 22%, refrigeration 17% and vacuum pumps 15%. Each participating farm received a comprehensive report with farm-specific energy saving recommendations with paybacks of five years or less. "We found that over 70% of the savings opportunities were related to water heating," says Mr Miller"

"As a result of the report, EECA has released a Request for Proposal to enhance electricity efficiency in New Zealand dairy sheds. The proposal focuses primarily on heat recovery technology. EECA is seeking to facilitate efficient transfer of heat from milk cooling process to the water heating process and thereby reduce dairy farm electricity use"
