The Solar Irradiance methodology is an automated system used to calculate
large-scale generation certificate (LGC) entitlement for eligible power stations of over 100 kilowatts (kW) and under one megawatt (MW) that participate in the
Large-scale Renewable Energy Target scheme.
The Solar Irradiance methodology provides several benefits for solar power stations:
The CER uses automation to calculate the eligible electricity for participating solar power stations and credits a nominated persons' REC Registry account each month with LGCs.
Eligible electricity is calculated by using the CER's generic irradiance model, combined with each solar power station's:
Shading and soiling on solar panels will be taken into account for calculating LGC entitlement. This is to increase accuracy of the irradiance model for each power station.
The solar power station will then be credited with one LGC per megawatt hour (MWh) of eligible electricity. Once LGCs are credited, nominated persons are required to pay the
LGC registration fee to access their LGC entitlement through the REC Registry.
The CER has designed documentasset: application form to opt-in to the Solar Irradiance methodology. The CER will assess a power station's eligibility to use the methodology based on the information provided in the form. Each power station will be assessed separately and will require an individual application form.
You do not need to complete the form if your power station is currently active on the Solar Irradiance methodology.
Your power station may be suitable for the Solar Irradiance methodology if it meets the following eligibility criteria:
You must comply with the following Solar Irradiance methodology requirements while using the methodology to calculate Large-scale Generation Certificate (LGC) eligibility.
compliance and reporting for further information.
Participants have the same responsibilities as when submitting LGCs without the Solar Irradiance method. Operating the Solar Irradiance methodology for a power station may be discontinued without prior notice at the CER's discretion. The nominated person for the power station will revert to a meter-based method if the Solar Irradiance methodology is discontinued.
For eligibility queries,
New solar power stations can opt-in to the Solar Irradiance methodology by lodging an accreditation application together with the Solar Irradiance methodology application form. If your power station is already accredited, you may send through an application form to opt-in to the methodology.
Follow the steps below to opt-in:
The CER will use information supplied during accreditation to assess eligibility.
Your power station will be switched to the Solar Irradiance methodology if approved and you will be notified.
Your power station requires a minimum of 3 months meter data before it can be moved to the Solar Irradiance methodology. This meter data is required to ensure that there are no issues that would prevent operation in the methodology.
You will automatically continue to operate under the Solar Irradiance methodology until you choose to opt-out, or until the date you have specified on the application form. Power stations can apply to opt-out at any time after the power station has participated for a minimum of three months. Applications will be processed at the end of the calendar year. To opt-out, email
CER-RET-LGCValidation@cer.gov.au with the power station name and accreditation code.
