liable entities

Determining liability

This page assists entities that are liable under the Renewable Energy Electricity Act 2000 in determining their liability for Large-scale Renewable Energy Target (LRET) and the Small-scale Renewable Energy Scheme (SRES). Please note there are different processes for determining your SRES and LRET liability and liable entities are responsible for surrendering certificates for both the schemes.

Process for determining liability

Determining your relevant acquisition/s (wholesale purchases of electricity)

Relevant acquisitions are typically large purchases of electricity that are made by electricity retailers or, in some circumstances, electricity generation companies, on liable grids.  Relevant acquisitions are required to be reported to the Clean Energy Regulator annually.

There are two types of relevant acquisitions:

  1. wholesale acquisitions - an acquisition of electricity from:
    • the Australian Energy Market Operator (AEMO) or a person or body prescribed like the Independent Market Operator (IMO); or
    • a person who did not acquire it from another person.
  2. notional wholesale acquisitions - can be an acquisition of electricity sold to an end user directly from the generator. In this scenario the generator is the RET liable entity.

Sections 31 to 34 of the Act provide details about relevant acquisitions.  Actual and potential RET liable entities are encouraged to review these sections and where required seek independent legal advice on liabilities under the Act.  Special exclusions apply for self-generators of electricity as stipulated under section 31 (2) (b) and section 33 (3) of the Act. However, the party must be able to demonstrate to the Clean Energy Regulator that they meet the self-generator criteria described in the Act and Regulations.

When are relevant acquisitions liable?

All relevant acquisitions of electricity on grids with an installed capacity of 100 MW or more are liable.  A grid is defined as a network of transmission and/or distribution lines that connects generators to end-users.  This means relevant acquisitions of electricity on grids across Australia and isolated grids supplying regional areas above this size are covered by the Act.

To calculate the installed capacity of a grid, RET liable entities should identify all of the RET power stations that are connected to the grid and add together the installed capacity of the RET power stations. RET liable entities can exclude standby or emergency plants and privately owned grid connected domestic generators.  A standby plant must, for the immediately preceding three years:

  • produce less than 50 GWh per annum; or
  • has less than a 5% load factor.  For example, if a power station generates less than 5% of its generation capacity.

As soon as a grid reaches the installed capacity of 100 MW or more, all relevant acquisitions on the grid become liable. Grid operators are obliged under section 31 (4) of the Act to inform the Regulator, within 28 days, of any changes to an existing grid that make the grid exceed the 100 MW threshold. 

There are many cases where a company could be liable under the legislation and appropriate legal advice should be sought by the relevant entity to confirm if the entity made a relevant acquisition under sections 31 – 34 of the Act, as the Clean Energy Regulator takes no responsibility for any decisions made on the basis of this information. 

Where is the liability reporting point?
Regulation 21 (1) (a) requires that RET liable entities:

For subsection 31 (3) of the Act, the amount of electricity acquired under a relevant acquisition is:

if the electricity is acquired from AEMO or IMO – the amount worked out on the basis of metering data used for AEMO or IMO settlement statements;

Regulation 21 (1) (b) – (e) provide alternate points of liability in relation to different metering parameters.  You should seek independent legal advice and where applicable discussions with the Regulator may be helpful as regulation 21 (2) specifies that the Regulator chooses in consultation with the RET liable entity the liability point for Regulation 21 (1) (b), (c) and (e).

For further information about determining the correct metering points please contact the RET Liability Assessment team in the Clean Energy Regulator.

Using Partial Exemption Certificates (PECs)

Companies conducting emission intensive trade exposed (EITE) activities can apply to the Clean Energy Regulator for PECs.  Eligible renewable energy target EITE activities are listed under Schedule 6 of the Regulations.  Assuming renewable energy target EITE companies are successful they are issued with a PEC. Renewable energy target EITE companies and RET liable entities can then negotiate and agree to the terms of PEC transfer.  PECs contain the following information:

  • Unique serial number
  • Year of PEC
  • MWh of exemption
  • Name of EITE activity
  • Name of liable entity

The RET liable entity uses PECs they receive to reduce their relevant acquisition which reduces their overall STC and LGC liability.  To reduce your MWh relevant acquisitions and certificate liabilities you must provide an original or copy of the PECs with the lodgement of the AEAS, as applicable.  If no PECs are included, no exemption will be used to determine your total reduced acquisitions

For further information regarding renewable energy target EITE activities and PECs see Emissions-Intensive-Trade-Exposed activities.

When do renewable energy target EITEs need to apply?

For information about PEC application lodgement dates see Timelines for PECs.

Determining your assessment year's reduced relevant acquisitions

Your assessment year's reduced acquisitions is determined by the following:

Relevant acquisitions of electricity in MWh (current year)

Add all relevant acquisitions as stipulated under the Act.

For more information, see the Determining your relevant acquisition/s section.

Partial Exemption Certificates (PECs) (current year)

The REC liable entity can include PECs in their AEAS to reduce their relevant acquisitions of electricity in MWh under the SRES and LRET if renewable energy target EITE companies provide PECs to the RET liable entity. 

For more information see the Partial Exemption Certificates (PECs) section.

Assessment year’s reduced acquisitions (current year)

Your assessment year’s reduced acquisitions is the basis of determining your annual STC and LGC liabilities.

The formula for determining your assessment year’s reduced acquisitions is as follows:

assessmentyearformula

Determining your STC liability

RET liable entities have a quarterly liability under the SRES. For reporting and surrender periods see Timelines.

Quarters 1 – 3

RET STC liability is determined by the following:

Previous year’s reduced acquisitions
  • This is what you reported in the AEAS for the previous year.  Relevant acquisitions in MWh less PECs in MWh for the previous year. 
  • This is the basis of calculating your required surrender amount for quarter 1 – 3.
Quarterly surrender percentage
  • The number of STCs required for surrender differs for each quarter.  The percentages to determine required surrender amounts are:
    • Quarter 1  - 35%
    • Quarter 2 and quarter 3  - 25%
Small-scale Technology Percentage (STP) (current year)
  • Establishes the rate of liability for the SRES
  • Removes STCs created in the given year from the market
  • Must be published in the regulations prior to 31 March of the year in which it applies
  • Section 40A (2) of the Act provides a default formula to calculate the STP if the Regulator does not set the STP.  This applies from 2012.
  • Under section 40C of the Act the Regulator is required to estimate the next 2 years STPs.  These estimates do not bind the Regulator in anyway.

For more information visit Small-scale Technology Percentage

Required surrender amount (based on previous year’s reduced acquisitions)

 

  • If the AEAS is submitted by 1 April of the given year the Regulator must give the liable entity written notice of their required surrender amounts for quarters 1 – 3.
  • It is advised that you wait for the Regulator to supply the estimated required surrender amount.
  • If applicable, apply for another amount, other than the proposed amount/required surrender amount (see 'Processes for applying for another surrender amount' on this page).

The formula for determining your required surrender amount (based on previous year’s reduced acquisitions) for quarters 1-3 is as follows:

requiredsurrenderamountformula

Quarter 4 – Determining your Net STC surrender requirement

RET STC liability is determined by the following:

Assessment year’s reduced acquisitions (current year) This is your relevant acquisitions of electricity in MWh (current year) minus partial Exemption Certificates (PECs) (current year) See 'Determining your assessment year’s reduced relevant acquisitions' on this page.  This is the basis of your STC liability and your Net STC surrender requirement.

Small-scale Technology Percentage (STP)(current year)

 

  • Establishes the rate of liability for the SRES
  • Removes STCs created in the given year from the market
  • Must be published in the regulations prior to 31 March of the year in which it applies
  • Section 40A (2) of the Act provides a default formula to calculate the STP if the Regulator does not set the STP.  This applies from 2012.
  • Under section 40C of the Act the Regulator is required to estimate the next 2 years STPs.  These estimates do not bind the Regulator in anyway.
  • For more information visit Small-scale Technology Percentage

Required surrender amounts for quarters 1 to 3

  • Your required surrender amounts for quarters 1 – 3 were provided to you by the Regulator prior to 15 April.  However, if you applied for another amount, your required surrender amount will be the amount that the Regulator determined.
  • For the purposes of the calculation below it does not matter whether you under or over surrendered STCs against your required surrender amount. The calculation below is the on the basis of providing your Net STC surrender requirement so that you acquit your LET STC liability with STCs rather than paying the Small-scale Technology Shortfall Charge (STSC).
  • However, if you surrendered:
    • STCs in addition to the required surrender amounts for quarters 1 – 3, you will reduce the amount of STCs you need to purchase to acquit your Net STC surrender requirement (quarter 4 annual compliance). Additionally any surplus STCs surrendered in quarter 4 can be used for future quarters.
    • less than the your required surrender amounts for quarters 1 – 3, you will need to pay a STSC for any certificate shortfall. See 'Paying the Small-scale Technology Shortfall Charge' on this page.
Net STC surrender requirement
  • Your Net STC surrender requirement allows you to determine the number of STCs you will need to surrender to fully acquit your current year STC liability without paying the STSC.

The formula for determining your Net STC surrender requirement for quarter 4 is as follows:

 required surrender formula quarter 4

Determining your LGC liability

RET liable entities have an annual liability under the LRET. For reporting and surrender periods see Timelines.

RET LGC liability is determined by the following:

Assessment year’s reduced acquisitions (current year) This is your relevant acquisitions of electricity in MWh (current year) minus the partial Exemption Certificates (PECs) (current year) (see Determining your assessment year’s reduced relevant acquisitions on this page).  This is the basis of your Net LGC liability.

Renewable Power Percentage (RPP)(current year)

  • Establishes the rate of liability for the LRET
  • Removes LGCs created in the given year from the market
  • Must be published in the regulations prior to 31 March of the year in which it applies
  • Section 39 (2) of the Act provides a default formula to calculate the RPP if the Regulator does not set the RPP.

For more information visit Renewable Power Percentage.

Carried forward balances
  • Where a RET liable entity fails to surrender sufficient LGCs to acquit their current LGC liabilities, the liable entity has a carried forward LGC shortfall or a LGC shortfall.  A liable entity has a:
    • carried forward LGC shortfall if it surrendered LGCs within 10 percent of the current LGC liability. 
      • In this case, the liable entity can carry the shortfall into future years until the shortfall becomes greater than 10 percent.  
      • Once the shortfall is greater than 10 percent the RET liable entity must pay the Large-scale Generation Shortfall Charge (LGSC).  
      • For the purpose of the formula below you add your carried forward balance.
    • LGC shortfall if it surrendered less than 90 percent of the current LGC liability.  
      • In this case, the liable entity pays the LGSC. 
      • For the purpose of the formula below you add your carried forward balance when you choose to redeem the LGSC (less an administration fee) by surrendering LGCs in addition to the current LGC liability (see Paying the Large-scale Generation Shortfall Charge on the Annual LGC Surrender page).
Net LGC RET liability surrender requirement
  • Your Net LGC liability surrender requirement allows you to determine the number of LGCs you will need to surrender to acquit your current year RET LGC liability without having a carried forward LGC shortfall.

Registering for an account

RET Liable entities need an account in the REC Registry in order to purchase, sell, voluntary surrender and mandatory surrender certificates.

Existing Account

If you already have an account in the REC Registry, are GST registered and wish to purchase STCs from the STC Clearing House, your account administrator will need to upgrade your account through your ‘manage account’ menu item and complete a Proof of Identity (PoI) check prior to using the STC Clearing House.

For more information visit About Proof of Identity Verification.  On this page you will find details on appropriate sources and have these on hand before starting the process.

New Account

If you do not have an account in the REC Registry, are GST registered and you wish to purchase and surrender certificates to acquit your certificate liability with LGCs or STCs you will need to open a ‘General’ account through the New Account Wizard.

If you wish to purchase STCs through the STC Clearing House you will need to complete a Proof of Identity (PoI) check. the wizard will assist you with completing the POI Verification process and lead you to create an account in the REC Registry.  For more information visit About the Proof of Identity Verification.  On this page you will find details on appropriate sources and have these on hand before starting the process.

You can register for a new REC Registry account as follows:

  1. Go to the New Account Wizard.
  2. If you do not wish to purchase STCs from the STC Clearing House go to Step 4.
  3. Follow the steps to the ‘General’ account pages
  4. If you wish to use the STC Clearing House complete the POI Verification process.
  5. Follow the steps to create an account in the REC Registry. 
  6. Once your application has been approved you are ready to purchase, sell, voluntary surrender and mandatory surrender certificates.

Applying for another surrender amount (the proposed amount)

Liable entities:

  • that lodge an Annual Energy Acquisition Statement (AEAS) can make applications under section 38AF of the Renewable Energy (Electricity) Act 2000 (the Act) to reduce or increase their previous year’s reduced acquisitions for the purpose of amending their required surrender amounts for quarters 1 to 3 of a year. 
  • that did not lodge an AEAS for the previous year can make an application under section 38AG of the Act to have an amount apply as if it were the previous years’ reduced acquisitions to ensure their required surrender amounts for quarters 1 to 3 are met.  It is the liable entity’s responsibility to make an application under 38AG of the Act if they make relevant acquisitions in a quarter.
  • that do not apply under section 38AG of the Act and make relevant acquisitions in a year will be issued with a default assessment under section 38AH of the Act.  Under this assessment, the liable entity will need to pay the small-scale technology shortfall charge (STSC).
Dates Forms and requirements
On or before 14 February Annual Energy Acquisition Statement (AEAS)
15 February – 14 March Liable entities can estimate their required surrender amounts for quarters 1 – 3 using section 38AA and 38AE of the Act just like the Regulator
15 March – 14 April Under section 40C of the Act Regulator to provide estimate of required surrender amounts for quarters 1 – 3 using section 38AE of the Act
15 February – before 1 October Under section 38AF liable entities can request a required surrender amount for quarters 1 – 3 if they lodge a AEAS
15 February – before 31 December Under section 38AG liable entities can request a required surrender amount for quarters 1 – 3 if they did not lodge a AEAS
31 December Under section 38AH of the Act Regulator issues a default required surrender amount if no AEAS lodged and liable entities did not apply under section 38AG of the Act

 

Applying under section 38AF

The process, including considerations, for RET liable entities to apply for a required surrender amount, instead of the previous year’s reduced acquisitions under section 38AF of the Act, is as follows:

1. Consider applying for required surrender amount

If RET liable entities apply for another required surrender amount (the proposed amount) for quarters 1-3 they should note:

  • that any future applications will not be considered by the Regulator.
  • the determination adjusts the required surrender amounts for quarters 1-3 for the year.

Why make an application?

RET liable entities may choose to lodge and apply under section 38AF of the Act for a variety of reasons. For example, if the RET liable entity lodged an AEAS (due 14 February) before 1 April and they anticipated that the Regulator’s estimate of the required surrender amounts for quarters 1 – 3 under section 40C will not align with actual relevant acquisitions, the RET liable entity may apply for another required surrender amount (the proposed amount) for quarters 1 – 3. This may occur if the liable entity lost/gained customers or lost/gained RET emission intensive trade exposed entity customers.

Do I have to make an application?

No, RET liable entities can choose to apply if they wish to do so.

Can I apply to have an amount (the proposed amount) apply to an individual quarter only?

No. The Regulator must use section 38AE of the Act to determine the proposed amount for quarters 1, 2 and 3. Section 38AE and 38AF of the Act does not allow individual required surrender amounts for quarters 1 – 3 to be calculated differently, including zero, for any quarter. As such, a liable entity that ceases trading or merges with another liable entity will need to meet their required surrender amounts for quarters 1 – 3 and submit an AEAS at the end of the year.

Are there risks in applying for a proposed amount?

Yes. Section 38AF(7) of the Act stipulates that if the assessment year’s reduced acquisitions exceed the determined amount under section 38AF(3)(a) of the Act by more than 10% then the assessment year’s reduced acquisitions will be used to calculate the required surrender amounts for quarters 1 – 3 using section 38AE of the Act.

An example is below which ignores compliance against annual (Q4) processes. 

Quarter

2011 
STC required surrender amount

 

(100,000 MWh section 38AF application approved and determined by the Regulator)

2011 
Actual STC required surrender amount

(150,000 MWh, actual data available at the 14 Feb 2012, more than 10% of 100,000 MWh section 38AF(7) and regulation 23A)

Number of STC’s surrendered in a quarter for the quarter

2 3, 700 (2) 5,550 (2) 3,700 -1,850
3 3,700 (2) 5, 550 (2) 3,700 -1,850

1 Calculated using section 38AE of the Act. Quarter 1 – Reduced acquisitions x 35% x 14.8% (Small-scale technology percentage (STP) for 2011).

2 Calculated using section 38AE of the Act. Quarter 2 and 3 – Reduced acquisitions x 25% x 14.8% (STP for 2011).

In this example:

  • the RET liable entity only surrendered STCs (column A) in line with the required surrender amounts for quarters 1 – 3 determined amount under section 38AF of the Act (column B).
  • the 2011 actual data exceeded the determined amount by more than 10% (refer to section 38AF(7) of the Act and regulation 23A of the Renewable Energy (Electricity) Regulations 2001. Therefore, the 2011 assessment year’s reduced acquisitions (actual data) is used to determine the required surrender amounts for quarters 1 – 3 (column C) using section 38AE of the Act.
  • the STC liable entity needs to pay a Small-scale Technology Shortfall Charge (STSC) of $65 per STC not surrendered in each quarter (column D).

Can I prevent a shortfall charge due to section 38AF(7)?

RET liable entities can surrender additional STCs in each quarter to minimise the impact of a potential shortfall, should their actual data exceed the determined amount by more than 10%.  

However, if insufficient STCs including surpluses are surrendered in a quarter then a shortfall charge may apply. Liable entities cannot make up shortfalls that occurred in quarter 1 – 3 in quarter 4.

For example, STCs surrendered in quarter 1 for quarter 1 can either acquit a potential shortfall or be carried forwarded to the next quarter. But additional STCs surrendered in quarter 2, 3 or 4 cannot be used to acquit a potential shortfall in previous quarters.  

2. Lodge application

RET liable entities must lodge the application before 1 October using the “year Application to have amount apply instead of previous years reduced acquisitions for Quarters 1 – 3 (Section 38AF of the Act)” form. 

3. Regulator considers application

The Regulator must consider the application and either:

  • determine that the proposed amount, or a different amount, is to apply instead of the amount of the previous year’s reduced acquisitions; or
  • refuse to make such a determination.

If the Regulator determines an amount other than the proposed amount applied for or refuses to make a determination under section 38AF of the Act, the determination or refusal to determine an amount can be reviewed under section 66 of the Act.  

4. Receive required surrender amount

RET liable entities receive their required surrender amounts for quarters 1-3.

  • the RET liable entity will receive an amount (the required surrender amount) that must be used for quarters 1-3 surrender purposes instead of the previous year's reduced acquisitions for quarter 1-3.
  • The Clean Energy Regulator updates the required surrender amount for quarters 1-3 in the RET liable entity's REC Registry Account.

 

Applying under section 38AG

The process for liable entities to apply for a required surrender amount as if it were the previous year’s reduced acquisitions (section 38AG) is as follows:

 

1. Consider applying for a required surrender amount

As soon as a RET liable entity becomes liable under the Act, they should contact the RET Liability Assessment Team and apply for the applicable surrender amounts.

If RET liable entities do not apply, the Regulator will impose required surrender amounts for the applicable quarters under section 38AH of the Act. In this case, the RET liable entity may not be able to surrender STCs for a particular quarter and will need to pay the small-scale technology shortfall charge.

Why make an application under section 38AG of the Act?

RET liable entities:

  • that did not lodge an AEAS (due 14 February) before 1 April, and did not have a liability in the previous year, may apply for required surrender amounts for quarters 1 – 3. Entities that are typically new to the market will need to lodge an application under section 38AG of the Act. It is the RET liable entity’s responsibility to make an application under 38AG of the Act if they make relevant acquisitions in a quarter.
  • that apply under section 38AG of the Act can specify the relevant quarter where relevant acquisitions were first made. Thus:
    • informing the Regulator when they first became liable under the Act;
    • ensuring STCs are surrendered to meet required surrender amounts for the applicable quarters ensuring that the payment of the STSC is potentially avoided.
2. Lodge application

RET liable entities must lodge the application before 31 December using the “year Application to have amount apply as if it were a previous years reduced acquisitions for Quarters 1 – 3 (38AG)” form.

 

3. Regulator considers application

The Regulator must consider the application and either 
 

  • determine that the proposed amount, or a different amount, is to apply instead of the amount of the previous year’s reduced acquisitions; or
  • refuse to make such a determination.

If the Regulator determines an amount other than the proposed amount applied for or refuses to make a determination under section 38AG of the Act, the determination or refusal to determine an amount can be reviewed under section 66 of the Act.

4. Receive required surrender amount

RET liable entities receive their required surrender amounts for quarters 1-3.

  • The RET liable entity will receive an amount (the proposed amount (i.e. the required surrender amount)) that must be used for quarters 1-3 surrender purposes as if it were the previous year's reduced acquisitions for quarters 1-3.

 

Issuing a default assessment under section 38AH

The process for the Clean Energy Regulator to calculate a default required surrender amount under section 38AH is as follows:

1. Determine if default

The Clean Energy Regulator to determine if a RET liable entity

  • did not lodge an AEAS (due 14 February) before 1 April
  • did not make an application under section 38AG
  • the Regulator refused to make a determination under section 38AG
2. Determine acquisitions and required surrender amount

Regulator to determine previous year’s reduced acquisitions and required surrender amount

  • If the RET liable entity made relevant acquisitions of electricity in the relevant quarter, the Regulator would determine the amount based on your assessment year’s reduced acquisitions.
  • If the RET liable entity did not make any relevant acquisitions of electricity in the relevant quarter, the Regulator would determine a amount of zero
3. Receive Regulator's determination

RET liable entity to receive Regulator's determination, which may include payment of the small-scale technology shortfall charge.
