Save energy during peak times

Small changes to the way you use energy really do make a difference. Be part of the solution! Find out how you can be involved in the latest initiatives to reduce peak demand.

What is Peak Demand?

Peak demand is when electricity usage on the network is at its highest, usually between 4pm and 8pm. In the long term it can lead to power outages and electricity price rises. If we reduce our peak demand at home and at work, everybody benefits.

Our innovative PeakSmart technologies are one of the ways we can all help manage demand. Learn more about PeakSmart events - the adjustments we make on days when the needle is in the red zone.

What's happening right now

Our live energy meter shows the real-time total electricity usage on our network and is updated every 30 minutes. It’s a great way to learn more about when peak demand occurs.

Small changes can make a big difference

Everyone’s different, but there’s one thing we all share. Whether you’re coming home from work, school, shopping or saving the world, we want to use electricity.

We turn on the light, the TV, stove, oven, dishwasher, washing machine, dryer, air-con, computer - in fact we all use a lot of electricity at the same time, usually between 4pm and 8pm each night. And on days that are very hot or very cold we use even more.

And we know what happens when we all want to use something at the same time.

It’s the same with electricity. When we all use it at the same time it puts strain on the network. It means more infrastructure like generators and high capacity powerlines are needed just to cope with those few times a year that everyone uses more electricity, which can add even more to everyone's power bill. Yet if we change our habits just a little, then demand on the network could be spread more evenly.

It's a simple as switching your hot water and pool pumps to economy tariffs, choosing energy efficient appliances, switching off the aircon and turning on a fan. Or, instead of cooking on a stove, fire up the barbecue. So think about what small changes you can make between 4 and 8, because small things can make a big difference.

The energy saver toolkit

Whether you’re at home or in the office, there are plenty of ways to save energy, help manage peak demand and reduce your power bill. Try these handy hints!

Not using it right now? Switch it off!

  • Switch off appliances like TVs, computers and game consoles when they’re not in use. Leaving them on ‘standby’ means they’re still using power.
  • Spring clean your second fridge or freezer and switch it off when not needed.
  • Going on holidays? Turn off all unnecessary appliances before you go.

We have the technology!

  • Swap your old power boards, light bulbs or chargers for energy efficient versions.
  • Switch your pool pump to an economy tariff or install one of the latest ‘five star energy’ efficient pool pump systems.
  • Switch your hot water system to an economy tariff.
  • Renovating or building? Take the opportunity to talk to your electrician about switching appliances to an economy tariff.

Keep your cool

  • Many people set their air-conditioners lower than they really need to be. Set your air-con to 24 degrees for maximum efficiency. Every degree lower could cost you up to 10% of your running costs!
  • Keep your filters clean. Your air-conditioner has to work much harder to cool or heat the room if it’s clogged with dust.
  • Consider using a fan in some rooms. Fans are much friendlier on your pocket (and the electricity network) than air-conditioners.
  • We remember to close doors and windows when it’s cold – but how about on a hot day? Shut doors and windows, close curtains, and lower external blinds to keep the heat out.

Laundry tips

  • Use your clothes line instead of your dryer. Did you know that sunshine is a great natural deodorizer?
  • Wash in cold water to keep water heating costs down, and do the laundry outside of 4pm to 8pm – the peak demand period for the electricity network.

Kitchen tricks

  • Run your dishwasher outside of 4pm to 8pm – the peak demand period for the electricity network.
  • Defrost your freezer regularly to help maintain efficiency. Ideally, the frost build up shouldn’t exceed a thickness of 6mm. A fuller freezer helps prevent heavy icing, too.
  • Ensure the seals on your fridge are in good working order to stop cold air getting out.
  • Cook on the BBQ or use the microwave instead of an electric stove, especially on those hot summer peak days.
