Energy Load Shifting Made Easy

Comments 0
by  |

Everyone wants to keep their electricity bills down, but with the latest energy price hikes it is becoming increasingly difficult. Well, if you have solar then we have some good news for you! With just some simple behavioural changes you could see your energy bills drop dramatically.

All you have to do is try ‘load shifting’. We show you how you can save by load shifting; check out our simple table broken down by each Australian state and by appliance, to see what potential savings you could make.

Load shifting appliances when you have solar

So what the heck is load shifting, anyway?

Load shifting means using your higher energy-sucking appliances during sunshine hours. If you were previously using those appliances in the morning or at night, you will be shifting your electricity ‘load’.

Since your electricity company nearly always charges you more for energy than what they pay you for your solar power, you can save a lot of money when you start powering these appliances with your solar system.

Whether you decide to run your pool pump between the hours of 9 – 3pm, or preset your dishwasher to run at 12pm instead of after dinner, every bit helps. These simple adjustments to your daily routine can save you hundreds of dollars every year.

Load shifting makes a substantial difference to the annual cost of your energy bill because the energy you use to power your devices is essentially free energy from the sun!

You can load shift by using a timer on your appliances, using a remote switching device, such as a WeMo, and by consciously using your appliances when you are home during daylight hours. You can use your Solar Analytics dashboard to see exactly when your solar production ramps up and tapers off to get it right.

Admittedly, load shifting all your appliances at once can be hard and impractical. Instead, why not start appliance by appliance? You could start with a high-impact appliance first (check our table below), such as the swimming pool pump, or the air conditioner, or any device that can be run during the middle of the day. Then sit back and watch smugly. Your savings will start immediately.

How much can I really save?

Energy is complicated. With so many different prices and tariffs and discounts, we get that sometimes it’s easier just to pay your bill. In fact, if you are lucky enough to still be receiving a high feed-in-tariff for exporting your solar to the grid, then you will likely still be gross metering, and will not be able to use your solar on-site at all.

But for the majority of us, load shifting is an easy way to make a difference to your bottom line. You might save a little more or a little less than someone in a different state with different tariffs, system size, and energy usage, but it’s a saving either way.  

We’ve taken the energy consumption data for 2017 from all Solar Analytics users, and compiled it to create a ‘typical Solar Analytics user’. They use washing machines, clothes dryers, dishwashers, hot water heaters, pool pumps, ceiling fans, vacuum cleaners and irons, and some even charge a Tesla electric vehicle. You may not have all of these appliances, and you may use other appliances more heavily (we're looking at you electric kettle), but our analysis should give you enough information to decide what to turn on and when.

We’ve taken the average tariff rates from real customer energy bills, so click below on your state and tariff type and take a look at your potential yearly savings.

What else can I do?

Load shifting is great, but we have also included some energy efficient techniques that can help cut your energy usage even further, such as using a pool cover, insulating your water heater or even disabling your dishwasher’s drying feature. Employing one of these techniques can make a difference.
