Synergy is working with Western Power and the City of Mandurah to develop a new Energy Storage Trial called "PowerBank" (Trial) at Meadow Springs. 

PowerBank is a 2 year Trial that will allow invited customers to make the most of their solar PV system by virtually** storing the excess energy generated (up to 8 Kwh/day).

Effectively, providing them with the benefits of a battery storage solution without having to install their own battery.

Check out how it works.

Heating and Cooling

Heating and cooling your home forms a pretty big part of your overall energy use, in fact by simply setting your heating to 19°C instead of 24°C in winter you could save up to $32/month^^, so it’s worth looking at ways to optimise your energy efficiency with the following energy saving tips.


  1. Don't crank the air conditioner

    It’s more energy efficient to heat or cool your house slowly over time, instead of turning the air conditioner up for ‘quicker’ results.

  2. Keep the cold in and the heat out, or vice versa

    Door snakes are inexpensive and can help stop air escaping from the bottom of doors.

  3. Try using a pedestal or ceiling fan instead of the reverse cycle air-con

    Fans are a much more energy efficient way to cool you down.

  4. Get your heater serviced regularly to keep it running efficiently

    Even cleaning the dust and fluff from the fan can save on your electricity costs in winter.

  5. Pull on your pullover

    Heaters are great, but see if a good old jumper can warm you up first.

  6. Take advantage of the sun

    In winter, open your curtains in the middle of the day to let the warm sun in. In summer, use your blinds to block out the sun’s heat.

  7. Rug up with extra blankets

    Put on some warm PJs and add a few extra blankets instead of an electric one.

  8. Electric blanket on, room heater off

    Once you’re nice and cosy in bed, you probably don’t need to heat the whole room.

Laundry and other

Laundries, bathrooms and pools can use about 27% of your household energy usage. This mainly comes through the energy it takes to heat water, but these other tips could help you reduce your energy, and water use.

  1. If the sun's out, get your laundry out

    Clothes dryers use a lot of energy, so when you can, use your clothesline.

  2. Clean out the lint filter of your dryer

    To keep your clothes dryer running efficiently, clean the lint filter after each load.

  3. Wash your clothes in cold water

    The cold water cycle will reduce your heating costs and your clothes will stay brighter for longer. Win win.

  4. Choose a washing machine with a good star rating

    Front loaders are generally more energy efficient than top loaders. Make sure you check the star energy ratings before you decide.

  5. Wash yourself quicker

    Take shorter showers is a common tip. An average a shower uses 12 litres of water every minute, so it makes sense.

  6. Put your pool pump on a timer

    Pool pumps use a fair bit of energy, so run them on a timer to reduce energy.

Computers and general appliance tips

These days we rely a lot on various appliances. The main way to save energy is to switch them off at the wall when you’re not using them.

  1. When charges aren't charging, switch them off

    Chargers slowly leak energy when they are left on, switch them off at the wall to save energy.

  2. Don't keep appliances on standby

    Appliances still use energy, so switch them off at the wall.

  3. Lets the stars choose your new appliance

    The energy star rating is an easy way to quickly see how energy efficient an appliance is.

  4. Consider upgrading really old appliances

    Old fridges and dishwashers are not generally as energy efficient as newer models. Check energy star ratings before buying new appliances.

  5. Let your computer's screen saver do its job sooner

    Adjust your computer’s eco-saver power settings so your screen switches off shortly after you stop using it.

  6. Switch printers, scanners, modems and other peripherals off at the wall when not in use

    Put these devices on a separate power board so you can turn them off without affecting your computer.

  7. Light your workspace not the entire room

    Using a lamp to light just your workspace is energy efficient and can help you concentrate.

  8. What to look for in a new computer

    Screen size matters. The bigger the screen, the more electricity is consumed, so choose appropriately.

  9. Clean your dishwasher filter regularly

    Your dishwasher cleans dishes, not itself, cleaning the filter will make it run better.

  10. Use a cold water connection for your dishwasher

    This will save on water heating costs.

  11. Only fill your kettle with the amount of water you need

    The water you don’t use will just get cold and need to be heated again.
