Higher profits due to:

1) Multiple reduction of useless costs

2) Protection against damage and losses

3) Additional profits by more efficiency

Dairy farms has savings potentials of about 30% to 50%.

In terms of farm sizes, these are:

  • with approx. 12-30 dairy cows approx. 2,500 to 3,400 EUR per year,
    thus approx. 25,000 to 34,000 EUR in 10 years.
  • with approx. 35-60 dairy cows approx. 4,600 to 6,800 EUR per year,
    thus approx. 46,000 to 68,000 EUR in 10 years.
  • with approx. 65-100 dairy cows approx. 7,500 to 12,000 EUR per year,
    thus approx. 75,000 to 120,000 EUR in 10 years.
of useless costs (including repairs) and consumption.

In a dairy farm with about 20 to 80 dairy cows

  1. the vacuum pump causes approx. 2000 to 8000 kWh to run uselessly every year.
  2. milk cooling consumes approx. 4000 to 16000 kWh unnecessarily every year.
  3. the fans consume several thousand kWh unnecessarily every year due to inaccurate control.
  4. heat stress in dairy cattle results in a loss of about 3% to 5% of the milk yield (many studies available on the internet).
You do not see these losses as clearly as a glowing light bulb.

But they are much higher.

Improvements are very profitable here!

The 2 farmers

Farmer 1

  1. said: I do not need to invest in conservation because I make my own electricity.
  2. He bought himself a large PV system and a large electricity storage unit.
  3. Experience: He cannot use the surplus PV yields and often has to give them away.
  4. From October to April, he often has to buy the electricity for his machines and motors, which run at permanent 100% power all the time.

Farmer 2

  1. said: First reduce consumption, and then produce the electricity yourself adequately.
  2. He retrofitted his vacuum pump, cooling, barn climate etc. with efficiency techniques and reduced the required power (kW) by approx. 65%.
  3. He bought a medium-sized PV system and a medium-sized electricity storage system, matching the current output.
  4. With the price difference of a large PV system to a medium-sized one, he bought the efficiency technologies, i.e. invested about as much as farmer 1.
  5. Experience: He rarely has a surplus and gives nothing away.
  6. His running costs are lower in the long run because his plants and motors run at 40% power on average, but could draw up to 100% power if needed..
The cheapest kilowatt hour is the one you do not use!
