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.

Switch and support renewable energy

Diamond Energy is excited to work with WinZero to help support their vision to create a sustainable community for current and future generations. 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 clean, green and low cost facilitating the timely transition, and well overdue retirement, of polluting 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. 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.
As a thank you, we will make an ongoing contribution to support the work of WinZero Gift Fund.
Yes I will move away from fossil fuels!

Switching your electricity to Diamond Energy only takes a few minutes. Get started here.
Our rates continue to be some of the most competitive in NSW 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.
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.
