We source electricity from renewable generators. We believe that electrification along with renewable generation is the future, so we don’t source natural gas and don’t supply natural gas to our customers.

At this stage, we can’t recommend a viable renewable supplier of natural gas. 

We are a 100% Australian owned electricity generation and retail electricity company.

Support 100% Renewable Electricity for SA

We are excited to work with Conservation SA to help support their vision of 100% renewable electricity for South Australia.
We believe that electricity from renewable generation will play a major role in helping combat climate change. Pure power from our natural renewable resources is both clean and low cost and enables the timely transition and well overdue retirement of polluting and aging coal-fired generation assets.
Instead of supporting coal generation, we support innovative renewable technologies throughout Australia including solar, wind, bio energy and wave. We also own and operate our own renewable energy generators – you can find out more about these projects here. We have no interest in coal generation, coal mining or alternative sources of gas (including coal seam gas).
Our passion for renewable energy has seen us highly ranked by Greenpeace since 2009 and the “only green ranked company retailing in SA” according to the Green Electricity Guide*.
You can make the switch for good to Diamond Energy and help support Conservation SA in their quest to deliver 100% renewable electricity for South Australia.
We sure can. We have been supplying electricity to customers in SA for over four years – providing competitive rates and great service. We also operate in VIC, NSW and QLD (Energex only).
Our rates continue to be some of the most competitive in SA for residential and small business customers. They continually appear as one of the lowest cost electricity retailers in government price comparison website, Energy Made Easy. View our offers for your home and business.
We topped the Green Electricity Guide* category nationally for electricity offers and feed in rates to solar customers.

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 – 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 one of our Pure Power solar installers.
No, your power will not be cut off. Switching just involves the transfer of information from your current electricity retailer to us.
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.
We will let you know the approximate date for your transfer in your welcome pack. You will transfer the next time your poles and wires company reads your meter.
You will receive:
  • a confirmation email and
  • a welcome pack from us over the next couple of business days outlining the offer and your electricity rates.
