How much will I be charged for electricity from the solar system?

Moving forward, you will continue to receive electricity from the solar system at the same low rate. Better, if you upgrade to Diamond Energy for grid electricity supply* and after we upgrade your electricity meter, you will receive a single bill from us that only charges you for the solar electricity you use – Even more savings!

Please note you can switch away from Diamond Energy grid supply electricity at any time, however if you leave us within any minimum supply period that may be included in your agreement, a termination fee of $22 (Incl. GST) may apply.

What if I don't upgrade my grid electricity to Diamond Energy?*

You have the choice of staying with your current electricity retailer and you will be continued to be billed as per your Express Solar agreement PPA. Diamond Energy will administer the billing and payments.

If you don’t switch to Diamond Energy, you will miss out on the opportunity for more savings and the simplicity of all of your electricity charges included in a single monthly bill.

What if I want to upgrade and am on a contract with my electricity retailer?

Don’t worry. If you are charged an exit fee, we will reimburse you with up to $100 credited to your Diamond Energy electricity account upon providing a copy of the fee to us.

Will I continue to receive my concessions and rebates?

Absolutely! If you are eligible, you will receive government funded concessions and rebates where applicable.

Can I switch my gas also?

We do not currently offer natural gas. You can stay with your current natural gas retailer.

Did you know that in many cases, utilising electricity in your property may be lower cost than natural gas?

Is there any disruption to my power during the upgrading process?

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

Will I have to pay for my electricity meter to be upgraded?

No. We will upgrade your electricity meter at no cost to you.

What happens after I sign up?

You will receive an auto-reply email. You will also receive a welcome pack over the next couple of business days outlining the offer and your electricity rates.

I've been contacted by VivoPower - how does this work moving forward?

VivoPower is an Australian and international company focused on the sale and installation and provision of small commercial and industrial systems direct to customers. They have written to their customers and informed them that Diamond Energy will provide a new billing service for their Express Solar PPA agreements.

If you have been contacted by VivoPower, you will start to see some newly formatted bills which will set out updated account details for payments and Diamond Energy will be in touch in the near future to arrange a time to install a new electricity meter for your solar installation.
