The Renewable Energy Target (RET) scheme

Recent amendments to the regulations

Amendments were made to the Renewable Energy (Electricity) Regulations 2001 on 8 December 2018 and 21 February 2019. These amendments clarify the eligibility of solar water heaters and solar (photovoltaic) small generation units and the audit requirements for applications to amend exemption certificates.

The amendment packages are available via the following links:

The RET scheme operates in two parts-the Small-scale Renewable Energy Scheme (SRES) and the Large-scale Renewable Energy Target (LRET).

Large-scale Renewable Energy Target

Wind power

The LRET creates a financial incentive for the establishment or expansion of renewable energy power stations, such as wind and solar farms or hydro-electric power stations. It does this by legislating demand for Large-scale Generation Certificates (LGCs). One LGC can be created for each megawatt-hour of eligible renewable electricity produced by an accredited renewable power station. LGCs can be sold to entities (mainly electricity retailers) who surrender them annually to the Clean Energy Regulator to demonstrate their compliance with the RET scheme's annual targets. The revenue earned by the power station for the sale of LGCs is additional to that received for the sale of the electricity generated.

The LRET includes legislated annual targets which will require significant investment in new renewable energy generation capacity in coming years. The large-scale targets ramp up until 2020 when the target will be 33,000 gigawatt-hours of renewable electricity generation.

Small-scale Renewable Energy Scheme

The SRES creates a financial incentive for households, small businesses and community groups to install eligible small-scale renewable energy systems such as solar water heaters, heat pumps, solar photovoltaic (PV) systems, small-scale wind systems, or small-scale hydro systems. It does this by legislating demand for Small-scale Technology Certificates (STCs). STCs are created for these systems at the time of installation, according to the amount of electricity they are expected to produce or displace in the future. For example, the SRES allows eligible solar PV systems to create, at the time of installation, STCs equivalent to the expected system output between the time of installation and the end of the RET scheme in 2030.

RET-liable entities with an obligation under the LRET also have a legal requirement under the SRES to buy STCs and surrender them to the Clean Energy Regulator on a quarterly basis.

While it is possible for owners of renewable energy systems to create and sell the STCs themselves, in practice, installers of these systems usually offer a discount on the price of an installation, or a cash payment, in return for the right to create the STCs.

Emissions-Intensive Trade-Exposed (EITE) activities under the RET

A 100 per cent exemption from RET liability is applied to electricity used in carrying out eligible emissions-intensive trade-exposed (EITE) activities. Companies that conduct an eligible EITE activity may be issued with an exemption certificate by the Clean Energy Regulator.

EITE activities are specified in the Renewable Energy (Electricity) Regulations 2001. Further information on determining EITE activity boundaries are described in the instrument Emissions-Intensive Trade-Exposed Activity Boundaries.

Amendments were made to the Renewable Energy (Electricity) Regulations 2001 on 14 December 2017. These amendments included the addition of an electricity use method for calculating exemption amounts for EITE activities and associated transitional arrangements. They also included a number of technical amendments to support the ongoing efficient operation of the scheme.

Further information on these amendments is available via the following links.

Reforms to the Renewable Energy Target

In 2015, the Australian Government settled on reforms to the RET, following careful consideration and extensive consultations.

The target for large-scale generation of 33,000 GWh in 2020 means that about 23.5 per cent of Australia's electricity generation in 2020 will be from renewable sources.

Amending legislation to implement the Government's reforms to the Renewable Energy Target (RET) was agreed to by the Australian Parliament on 23 June 2015.

The package of reforms included measures to provide certainty to industry, encourage further investment in renewable energy and better reflect market conditions.

The RET was amended to:

  • protect Australian jobs and help industries remain competitive by increasing assistance for all emissions-intensive trade-exposed industries to 100 per cent exemptions from all RET costs
  • remove the requirement for biennial reviews of the scheme and replace them with regular status updates by the Clean Energy Regulator, to provide more certainty to industry and transparency to consumers
  • reinstate biomass from native forest wood waste as an eligible source of renewable energy, including the same safeguards that were in place prior to removal of this source from eligibility in late 2011.

RET Scheme Legislation

The legislation and regulations under which the RET scheme is administered are available via the following links:

Clean Energy Regulator

The Clean Energy Regulator oversees the operation of the RET scheme in accordance with the RET legislation. The Department of the Environment provides policy advice and implementation support for the scheme.

Further information about the RET, including fact sheets, registration and accreditation forms can be found on the Clean Energy Regulator's website.

Review of the RET Scheme

A number of reviews of the RET scheme legislation have been conducted. On 17 February 2014, the Minister for the Environment and Minister for Industry announced arrangements for a review by an Expert Panel.

The Expert Panel has completed its review and provided a report to the Government. The report and further information about the review, including the Terms of Reference, can be found on the Department of the Prime Minister and Cabinet website:

The Climate Change Authority's statutory review of the operation of the RET under s162 of the Renewable Energy (Electricity) Act 2000 was presented to the Government on 22 December 2014 and tabled in both Houses of Parliament early in 2015. The Government's response to this review was tabled in Parliament on 7 August 2015.

Other support for renewables

Australian Renewable Energy Agency

The independent Australian Renewable Energy Agency (ARENA) complements the RET scheme. ARENA streamlines and coordinates the administration of support for research and development, demonstration and commercialisation of renewable energy technologies. Australian Renewable Energy Agency web site.

Solar Communities

The $5 million Solar Communities program will support local responses to climate change and help deliver lower electricity costs for community organisations.

Solar Towns

The Solar Towns Programme will provide Australian communities with an opportunity to engage at a local level with clean renewable energy, improve local environments, generate a sense of community ownership and self-reliance, and improve local community outcomes..
