Dairy farm energy efficiency tool

Find out how energy use on your dairy farm compares to 150 others across New Zealand – and what savings you could make through energy improvements in your milking shed.

Do you have a heat recovery system? Heat removed during the milk chilling process is often wasted - use this resource to heat water stored for cleaning, and cut your milking shed electricity bill by up to 30%. Often pays back in less than 2 years, and reduces your exposure to fluctuating milk-solid prices.
Is your vat insulated? Insulate the vat to reduce heat gain, thus reducing the load on your refrigeration system.
Do you have a variable speed drive vacuum pump? Variable Speed Drives (VSDs) enable the pump to change speeds to match demand for pressure from the system. That is, if more cows are connected to milking cups then the speed of the pump is increased to match the demand for vacuum and vice versa as cups are taken off cows. VSDs also reduce animal stress during milking, somatic cell count (SCC) and motor wear and tear as the pump is run at lower speeds.
Do you have a fresh water irrigation system on your dairy shed bill? Most farms will have separate billing for fresh water irrigation systems, but if your system is included on your dairy shed energy bill, then tick this box, and we will adjust your potential energy savings to suit.
