Farm Profile

A Central West Queensland sheep and beef cattle property running approximately 3,000 head could benefit from implementation of easy low-cost efficiency wins and improve on current solar export restrictions due to a SWER line connection.

The farm is generally a low energy user, with a number of small bore and transfer pumps for stock watering. The property currently has a 10kW Solar system coupled to 10kWh of battery storage

The energy audit initially identified low cost easy wins including:

  • Replacing door seals on the cold room
  • The use of a time clock on the hot water system
  • New LED lighting
Recommendation Cost to Implement ($) Energy Savings (kWh) Savings ($) Payback Period (Years)
Replace door seals 520 550 138 3.8
Hot water with time clock 380 1,618 295 13
LED lighting 530 1,052 255 2.1

 

Low cost wins onsite could lead to a potential energy savings of 3220kWh and $688 per annum. Replacing both the door seals and the LED lighting is highly recommended showing quick paybacks, with works on the hot water system at the discretion of the farm.

The farm has the potential for further reductions in energy use and practice change by reducing the time spent from switching of pumps, this could be achieved by:

  • Increasing the current battery storage onsite
  • Upgrading the current air conditioning unit
  • Installing 4G remote monitoring on both bore pumps
Recommendation Cost to Implement ($) Energy Savings (kWh) Savings ($) Payback Period (Years)
Increased Battery Storage 19,500 7,300 1,862 10
Replace Air Conditioning Unit 6,950 2,188 553 12.6
Install 2x 4G Remote Monitoring 3,000 1,380 364 8.2

 

As the farm has a SWER line connection, export of power from the solar systems are limited.  The installation of two additional 10kW batteries will allow a saving of approximately 7,300kWh per annum as excess solar energy generated can be stored. Battery capacity onsite would be increased to 40kW with additional savings of $1,862 from changes to the current system. Battery storage is worth considering on most SWER lines and at a payback of 10 years the farm should apply discretion to implement.

Productivity gains are not limited to an increase in units of output. Due to the location and size of the property, the audit recommended adopting the use of 4G remote monitoring on two pumps. This enables the pumps to be controlled from the farmhouse, negating the distances required to turn the pump off. As the pump can left running overnight the monitoring will allow a reduction in energy use of 1,380kWh per annum and more time available to be spent on improving the business in other areas.
