Energy saving opportunities
There are several areas where you could make substantial savings on electricity use in your dairy shed. Use our dairy farm energy efficiency tool to find out how efficient your farm is compared to similar farms - and how much you could save.
This is the best place to start as it accounts for about a quarter of your dairy shed electricity bill and has the highest potential for savings. Through a combination of clever technologies and tweaks to the way you run your shed you could save up to 75% on your water heating costs.
There are 3 main technologies to help you improve water heating efficiency.
Heat recovery technology can cut dairy shed electricity bills by up to 30%
Recovering the heat produced during the milk chilling process provides an additional source of energy which can be used by your dairy shed hot water heating system, reducing the amount of electricity needed.
Payback on investing in heat recovery technology typically takes 2 to 5 years, although it can be less than a year for large farms.
Variable speed drive (VSD)
Enable the pump to change speeds to match demand for pressure from the system. If more cows are connected to the milking cups, 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.
Potential savings: 10% to 15%.
Insulating your milk vat could increase your refrigeration capacity at minimal cost, and save you money. Find out how much you could save with our milk vat insulation savings calculator.
Potential savings: 3% to 6%.
