Did you know that up to half your energy bill could be down to your lighting*?

More energy efficient lighting is a great way to save you money on your electricity bill. And you can do so much more than just replace the light bulbs:

  • Improve the way your employees use lights
  • Think about how you use light in different rooms
  • Look at the equipment that creates and reflects light
  • Automate switches to control when the lights go on and off, and how bright they shine
  • Make light levels for each area appropriate for the task – brighter for more difficult tasks and dimmer for walkways, break rooms and simpler tasks
  • Use room colour or natural light to improve light levels
  • Move workspaces to brighter areas or away from glare
  • Replace your old setup with more energy efficient lights.

Depending on your industry, you could be spending 85% of your energy budget on refrigeration *.

Here are some simple changes you can make that’ll save you money:

  • Try to cool products before refrigerating them
  • Put more insulation on your pipes and keep them away from anything hot
  • Make sure your processing equipment works well andlook for any unexpected heat spikes, e.g. From pasteurisers
  • Make sure your products aren’t overheated tobegin with
  • Make sure cooling is actually needed, or just raise the temperature of the coolant if possible
  • Try to avoid heat from the sun by keeping your refrigerators well shaded
  • Keep your cooling equipment away from heat sources (such as radiators and air-conditioning equipment)
  • Try to keep your cooled spaces airtight so warm air can’t get in
  • Turn your pumps off when they’re notneeded
  • Minimise the time your staff spend in, or passing through, cool areas - improving the layout of your facilities could help too.

Compressed air systems use around 10% of the total electricity used in Australian industry *.

Over time this adds up, but you’ll save money if you:

  • Find and fix leaks – leaks can waste up to 50% of your compressed air
  • Minimise pressure drop – your compressed air system should have a pressure drop of less than 10% between the compressor outlet and all points of use
  • Review your air receivers – if your receiver is too small, your compressor might be running longer than it needs to
  • Maintain your separators, filters, dryers and valves – if they’re faulty or clogged, they can waste energy and result in higher maintenance costs.

Process-heating systems can make up around 17% of the electricity used by industry.

Your steam generation system could be using up to 34% of your production systems total energy *With some simple, low cost maintenance and improvements, you should be able to reduce the energy used by your steam, hot water and process-heating systems by up to 10%:

  • Improve the operation and maintenance of boilers
  • Improve your water treatment and boiler water conditioning
  • Preheat combustion air
  • Increase boiler feedwater temperature by 7°C
  • Use economisers.

The Retailer Energy Efficiency Scheme (REES) in South Australia

The South Australian Government has an energy efficiency scheme – offering services such as energy audits, installation of energy efficient products and a range of advice. For South Australian businesses, the products available under the Scheme include free or reduced price lighting upgrades*.

Smaller businesses can participate in the scheme up to the value of 900 certificates (for sites with <160MWh in the last 12 months per National Meter Identifier).

Larger (C&I) sites can participate in the scheme on a contribution model.  $1.40 + GST per certificate to participate (for sites with >160MWh in the last 12 months per National Meter Identifier).

Find out how Origin is involved in REES.

Call Energy Smart on 1800 331 337 or visit the South Australian Government Energy Smart site.

* The existing lighting equipment must be in working order at the time of the upgrade. Some upgrades may be excluded based on specific scheme eligibility requirements.
