Make the switch to Diamond Energy to support renewable energy

Are you tired of all the talk and lack of action on climate change?

CABA Progressive invites you to be part of the solution by taking the simple step to switch to Diamond Energy as your electricity retailer and make your electricity dollar count – switching is quick and easy, just sign up online.

At Diamond Energy we believe new renewable generation projects are capable of making a difference and are part of the solution and you can also be part of the solution through the choice of electricity retailer you spend your electricity dollars with.

We are an electricity retailer supporting new renewable generation derived from Australia’s pure resources. We own and operate our own GreenPower Accredited renewable energy generators and support other new innovative renewable energy technologies, such as bio energy, wave, wind and solar projects to be delivered across the country. We are your Pure Power People.

We were rated in Greenpeace Australia Green Electricity Guide 2014 as the highest ranked operating electricity retailer in NSW, QLD and SA and also ranked highly in VIC – we openly support expanding the Renewable Energy Target and we don’t have interests in coal generators, coal mining, natural gas or alternative sources of gas (including coal seam gas). 

It is exciting to know that the more residential and business customer we have, the more new renewable generation projects we can support. On top of all that, our rates are very competitive, so you don’t have to pay more to do the right thing.

Take a simple step to be part of the solution and make your electricity dollar count!




If you would prefer to talk to us and experience our personalised service, you can call between 8.30am and 6.00pm weekdays on 1300 838 009.


Here are some common questions and answers about switching to Diamond Energy.

Can Diamond Energy supply power to my property?

We have have been supplying electricity to residential and small business customers in VIC, NSW, SA and QLD (Energex region) for over three years – providing competitive rates and great service.

Is there any disruption to my power supply during the switching process?

No, your power will not be cut off. Switching just involves the transfer of information from your current electricity retailer to us. 

What if I'm on a contract but want to switch?

Switching to Diamond Energy is easy. We handle it for you, including contacting your existing retailer. If you are on a contract with your existing electricity retailer you can find out from them whether there are any exit fees associated with changing, but ultimately they can’t stop you switching. 

I have solar panels. Does Diamond Energy support solar customers?

We service thousands of solar customers across the country by offering some of the most competitive rates and one of the highest feed in rates.

If you recognised the benefits of solar years ago, then you may already be receiving a state based feed in tariff under a scheme that is now closed to new recipients. Subject to eligibility check, you will continue to receive your feed in tariff when you switch.

If you are eligible for a net feed in tariff, we will top it up with our standard rate (currently 8c/kWh) – one of the highest available.

We also have programs that offer even higher feed in rates if you are looking to purchase a new solar system through on of our Pure Power solar installers.

Where does Diamond Energy source electricity from?

Diamond Energy sources electricity from generators that are Renewable Energy Target (RET) Scheme approved and accredited to produce 100% GreenPower, including Diamond Energy’s own Tatura and Shepparton biogas plants.

We balance our customers usage with the electricity we buy from these projects.

We also source electricity from rooftops of thousands of solar customers across the country that are exporting to the grid.

The growing support of our customers enables us to support more new renewable generation projects.

Does Diamond Energy offer GreenPower products?

Yes. Diamond Energy offers Diamond Pure Plus, a GreenPower Accredited product range for those wanting to make the extra commitments to support renewable energy products.

What difference will switching make?

The more customers that switch to Diamond Energy, the more new renewable energy generation projects we can support in Australia. We are proud to work in regional areas of Australia supporting local investment and employment benefits.

You can find out more about the innovative generation projects we support in Australia.

How long does it take for Diamond Energy to become my retailer once I have completed the online application?

We will let you know the approximate date for the transfer in your welcome pack. In most cases you will transfer the next time your poles and wires company reads your meter. 

What happens after I sign up online?

  • You will receive an auto-reply email.
  • You will receive a welcome pack from us over the next couple of business days outlining the offer, your electricity rates and the approximate date in which you will transfer to us.
