Facilities generating or dispatching electricity from eligible renewable energy sources can participate in the Renewable Electricity Guarantee of Origin (REGO).

Facilities include renewable electricity generation facilities and energy storage facilities.

To take part, follow the step-by-step process for participating in the REGO.

Once your facility is registered, you can create REGO certificates for eligible electricity either generated or dispatched by a facility on or after the date of registration. This includes renewable electricity that has been stored in an energy storage system and then dispatched.

Facility types

Facilities can be electricity generation systems, energy storage systems or a combination of systems.

Accredited power stations

Accredited power stations are facilities that have been accredited in the Large-scale Renewable Energy Target (LRET). If your facility is already accredited, you must apply for the REGO under this option.

info

If you want to participate in the REGO using an already accredited power station, you still need to follow our step-by-step process.

Relevant legislation

Electricity generation systems

Electricity generation systems are facilities that generate electricity from eligible renewable sources and are not accredited power stations in the LRET.

Relevant legislation

  • Section 79 of the GO Act

Energy storage systems

Energy storage systems are facilities that can store and dispatch electricity for later use. The facility takes electricity and stores it as some form of energy (e.g. chemical, mechanical, kinetic, thermal or gravitational). They can include: 

  • battery systems
  • pumped hydro storage systems not already accredited under the Renewable Energy Target
  • any other energy storage systems that are connected to an electrical grid.

The eligible storage types are described in the Future Made in Australia (Guarantee of Origin) Rules 2025 (GO Rules).

Relevant legislation

  • Section 80 of the GO Act
  • Schedule 4 of the GO Rules

Direct supply relationships

To create REGO certificates, eligible registered persons of energy storage systems must either: 

  • surrender or retire an appropriate number of large-scale generation certificates or REGO certificates
  • use electricity that is directly supplied from an eligible renewable electricity generation facility.

To have a direct supply relationship, an energy storage system and an electricity generation system must meet the following conditions: 

  • electricity is transferred to the energy storage system directly from the electricity generation system
  • the energy storage system, the electricity generation system and the transfer, meet the requirements prescribed by the Rules.

Aggregated systems (not available yet)

warning

While aggregated systems are eligible facilities, you won’t be able to register one until rules are made for these systems in the GO Rules.

Aggregated systems are facilities that generate or store electricity. They can include: 

  • 2 or more electricity generation systems
  • 2 or more energy storage systems
  • at least one electricity generation system and at least one energy storage system.

Relevant legislation

  • Sections 70 and 71 of the GO Act

Register your facility

Who can apply

Facility owners or operators can apply to register their facility.

If a facility has more than one owner, they must all agree on who will submit the application. That person will become the eligible registered person for the facility. Eligible registered persons:

  • can create REGO certificates
  • are responsible for facility requirements and ongoing compliance.

When to submit

If your facility is new, you should start drafting your application in Online Services 10 to 12 weeks before your facility is operational. You can save your progress as you go.

If your facility is already generating or storing electricity, you should submit your application as soon as possible. 

You can only claim REGO certificates for electricity generated or dispatched on or after the date the facility is first registered.

Certificates must be claimed within 12 months of the generation or dispatch occurring. For example, if you want to register certificates for electricity generated or dispatched in January 2026, your facility registration must be approved before the generation or dispatch occurs, and you must submit the certificate claim before 1 February 2027.

Complete your application

While drafting your application in Online Services, upload your supporting documentation, including:

  • approvals, component documentation and other evidence to support the application
  • metering and certificate calculation method
  • system owner or operator agreement.

You must complete a separate application for each facility you're applying for.

Need help applying?

Registering your facility is an important step to participate in the GO Scheme. We’re here to support you through the process and help you understand the requirements.

For support, email us at rego-assessments@cer.gov.au.

Withdraw your application

You can withdraw your application at any time for any reason. For example, if:

  • your facility is delayed
  • you can't provide all supporting information and documentation.

You can submit a new application later if you withdraw an application, but you may have to pay a new fee.

Complete and incomplete applications

Once we receive an application, we check if the application is complete or incomplete.

Complete applications include:

  • all required information and supporting documentation
  • reasonable justification if certain approvals aren't applicable to your facility
  • a fee payment.

Incomplete applications:

  • are left intentionally blank
  • have too much missing information
  • don’t meet all the requirements
  • are not accompanied by a fee payment.

For support, read our Online Services user guide – register a REGO facility.

Await the outcome

We’ll assess your application to determine if it meets the requirements for a complete application and eligibility criteria.

If we need more information, we'll send a request for further information through Online Services. Make sure you respond to all points in your request. 

If you don’t respond to our request for further information by the deadline, we may cease considering your application.  If you still want to register your facility, you’ll need to fill out a new application form and provide the missing documents listed in our original request for further information.

We may refuse your application if:

  • it's not complete
  • it's not eligible
  • it's missing required documents.

If your application is approved, we'll give your facility a unique identification code.

If your application is refused, you can request an internal review of the decision.

New facilities, or facilities that first generated electricity after 1 January 1997, will not have 1997 baseline. For other facilities we’ll determine your baseline when registering your facility. Facilities may qualify for a special baseline.

Relevant legislation

  • Sections 78, 79, 80 and 81 of the Act
  • Section 38, 39, 40 and 41 of the Rules
  • Section 153 of the Act

Manage your facility

Eligible registered persons are responsible for facility requirements and ongoing compliance. They must be an owner, operator or aggregator of the facility.

Change the eligible registered person

You can apply to change who the eligible registered person is after registration. To do this, email us at rego-assessments@cer.gov.au

Facility updates

An eligible registered person can report facility updates or notify us of other events by emailing rego-assessments@cer.gov.au.

You must notify us of certain events within 1 month of them happening. Find out what you need to tell us.

  • A component is added to or removed from the facility
  • The facility no longer complies with a requirement prescribed by the facility’s measurement standard
  • The facility starts to generate electricity from a different eligible renewable energy source
  • For a facility that is an electricity generation system:
    • the facility starts using an energy source that isn’t a recorded energy source
    • the facility stops using a recorded energy source for more than one month (for a reason other than periodic access to that energy source)
    • the eligible registered person intends a facility to permanently stop using a recorded energy source.
  • For a facility that is a hydro system – a change in water flows for the system
  • For a facility that is an energy storage system – the facility has added or removed a connection for the import of electricity
  • The facility takes part in another scheme
  • The facility stops taking part in another scheme
  • There’s a contravention of Commonwealth, state, territory or local government planning and approval requirements in relation to the facility
