Guide to creating large-scale generation certificates in the REC Registry

17 April 2020

This is a step-by-step guide on how to create large-scale generation certificates (LGCs) for eligible electricity generated by your accredited power station. The submitting a large-scale generation certificate claim application video shows nominated persons how to claim LGCs in the REC Registry.

To create LGCs in the REC Registry follow these steps:

  1. Before you can create LGCs, you must have already entered power station generation data for the corresponding month/s. You can create LGCs directly after entering generation data for any given month, or create LGCs in bulk for all power stations where generation data has been entered and eligible LGCs have not yet been claimed.

    Two ways to create LGCs
    Immediately after entering generation dataBulk create LGCs

    After entering your power station generation data in the R​EC Registry, click on the 'Create LGCs' button. This will open the 'Create large-scale generation certificates' (LGCs) screen.

    Your generation month with LGCs pending creation will be filtered the power station, generation year and generation month you have just entered data for.

    • From the left hand menu, navigate to 'Renewable energy systems' and select 'Create LGCs'.
    • Select the power station/s, month/s and year/s you want to create LGCs for.

    You will be presented with selected power stations with generation months that have LGCs pending creation.

  2. The following fields in the 'Create LGCs' table are auto-populated based upon the generation data you have previously entered, any claims previously made for this generation month, and any LGCs previously validated by the Clean Energy Regulator:

    • fuel source

    • LGC eligibility

    • LGCs created

    • LGCs failed, and

    • LGCs remaining to be created.

  3. The 'Number of LGCs to create' text field will be pre-filled to equal the number of LGCs remaining to be created. You can reduce this number so that you are not creating for your full LGC entitlement.

    The number of LGCs to be created must be less than or equal to the number of LGCs remaining to be created.

    The total number of LGCs created cannot exceed the LGC eligibility for any given month.

  4. The 'Certificate tag' field can be used to enter a unique reference if required by your business processes. This field can also be left blank.

  5. Select the generation month for each power station that you want to create LGCs for by checking the tick box in the last column of each row.

  6. For the generation months you have selected, provide responses to the 'Standing notice' questions. If there are any breaches or compliance issues for any power stations during a generation month, you will have to claim LGCs for this power station individually.

    If there are any documents relevant to your response to the standing notice questions, please email

  7. Read through the 'Declaration' section and check the tick box to acknowledge that you understand and agree to the declaration.

  8. Click on the 'Submit' button.

Your LGCs are now pending validation by the Clean Energy Regulator. The Clean Energy Regulator may take up to 28 days to validate a claim for LGCs. You can track your LGCs in the REC Registry, including the ability to see how many LGCs have been passed, failed, are pending or under assessment, or pending validation.

When the Clean Energy Regulator has validated your LGCs, you are required to pay the LGC creation fee before they are registered and added to your holdings.

If the Clean Energy Regulator fails certificates, you will receive a notification. You can amend and resubmit a claim for validation and registration. See failed certificates for more information.
