CoolSaver is an Endeavour Energy initiative to help our customers save money and use electricity more efficiently and effectively.

This program also addresses the challenge of peak demand usage periods, where large numbers of households use energy at the same time during hot periods. Watch this video to learn about CoolSaver.

What's the problem with peak demand?

High energy-consuming appliances like air conditioners are key contributors to peak demand, and their use only continues to rise. So, rather than building additional electricity network that’ll be used only a few days a year, we’re going to reduce peak demand through energy-saving initiatives.

As a socially responsible business, we’ve developed a suite of programs to support our sustainable approach to energy consumption. CoolSaver is one of them and you’re invited to take part.  Watch this video to learn about peak demand.

Comfort, control and savings are waiting for you

CoolSaver helps trim the energy usage of your air conditioner during times of peak demand – which will trim your bills too. We will reward you for taking part in the program with a smart thermostat (valued at $199) that will make your air conditioner smarter.

This device allows you to:

  • control your air conditioner from anywhere, anytime using your smart phone
  • monitor the temperature and humidity, and change your air conditioner settings
  • voice control your air conditioner (if you have Google Assistant, Alexa or Siri)
  • set unlimited 7-day scheduling for your air conditioner
  • automatically turn your air conditioner on or off when you enter or leave the room.

What does CoolSaver involve?

Your smart thermostat will be accessed by Endeavour Energy on ‘Event days’ only. During this peak demand time between 1pm and 8pm, for up to 4 hours your air conditioner will automatically increase in temperature with the aim of lowering its energy consumption. We will notify you of Event days via an email and/or text before the temperature increase occurs. Click here for some cooling tips.

Endeavour Energy will select up to 20 of these Event days in total during the summer period from 1 November 2021 to 31 March 2022. These particular days will be based on when we expect a series of hot days to occur, however weekends and public holidays are excluded.
