Determination

Application for authorisation AA1000484

lodged by the

Australian Energy Market Operator (AEMO)

in respect of cooperation and information sharing for the purpose of

responding to effects of the COVID-19 pandemic on the energy system

Authorisation number: AA1000484

17 September 2020

Commissioners:

Sims

Summary

The ACCC has decided to grant conditional authorisation to enable the Australian

Energy Market Operator (AEMO) and participants in the Australian gas and/or

electricity markets to cooperate to ensure the ongoing safety, security, or reliability of

Australian energy systems during the COVID- 19 pandemic by:

a) sharing information regarding ongoing operation at their facilities

b) co-ordinating repairs and maintenance

c) sharing essential personnel

d) sharing essential inputs

Conduct between energy market participants under the authorisation must be

facilitated by AEMO and does not allow for information sharing or agreements about

the wholesale or retail price of energy, retail cost or profits.

The ACCC grants conditional authorisation until 31 May 2021. This is subject to four

conditions, which impose reporting requirements on AEMO, particular reporting

requirements on conduct undertaken by Liquefied Natural Gas (LNG) producers,

requires that agreements formed under the authorisation not endure beyond the

period of authorisation and sets out a process for adding other industry participants

to the authorisation.

The ACCC has decided to grant authorisation until 31 May 2021.

1. The application for authorisation

1.1. On 30 March 2020, the Australian Energy Market Operator (AEMO), on behalf of itself,

AEMO Industry Participants

and Other Approved Participants

(collectively, the

Participants) lodged application for authorisation AA1000484 with the Australian

Competition and Consumer Commission (the ACCC). This application for authorisation

AA1000484 was made under subsection 88(1) of the Competition and Consumer Act

2010 (Cth) (the Act).

1.2. The ACCC can grant authorisation which provides businesses with legal protection for

arrangements that may otherwise risk breaching the law but are not harmful to

competition and/or are likely to result in overall public benefits.

1.3. AEMO also requested the ACCC grant, under subsection 91(2) of the Act, interim

authorisation to enable the Participants to engage in the Proposed Conduct

while the

ACCC is considering the substantive application. The ACCC has issued three interim

authorisations, reflecting developments in the impact of COVID-19 in Australia and

amendments to the conduct for which AEMO was seeking authorisation. A summary of

these interim authorisations (including the dates on which they were issued and

revoked) is set out in section 6.

As defined at paragraph 1.4 a), below.

As defined at paragraph 1.4 b), below.

See paragraphs 1.5 to 1.8, below.

The Applicant and Participants

1.4. AEMO was established by the Council of Australian Governments in 2009 to manage

the National Electricity Market (NEM) and the eastern and south-eastern states and

Australian gas markets. This role has expanded to now include responsibility for power

in Western Australia and various gas market functions. The application was lodged by

AEMO on behalf of itself and:

a) AEMO Industry Participants:

These are participants in Australian gas and/or electricity markets and their related

bodies corporate that are registered, or with an approved exemption, in respect of

markets and systems operated or managed by AEMO.

AEMO Industry Participants means each of the parties specified in Annexure D

to this determination.

b) Other Approved Participants:

Any other parties involved in energy or related sectors who in the future wish to

engage in the Proposed Conduct, provided the ACCC’s prior approval is obtained

through the process set out in condition 4 (see paragraphs 5.13 and 5.14), below.

The Proposed Conduct

1.5. Following amendments to the application for authorisation, AEMO is seeking

authorisation to discuss, enter into or give effect to any contract, arrangement or

understanding between the Participants, or engage in any conduct, which has the

purpose of:

a) ensuring the safe, secure and/or reliable operation of Australia’s energy systems

and/or the continued operation and integrity of the wholesale markets that

underpin energy supply during the COVID-19 pandemic;

b) ensuring ongoing energy supply to support consumers, businesses, government

operations and the economy during the COVID-19 pandemic;

c) minimising the risk of any energy outages during the COVID-19 pandemic;

d) ensuring that there are sufficient resources to maintain and operate energy

infrastructure, including personnel and essential inputs such as fuel, parts and

equipment; or

e) planning or preparing for the impacts of the COVID-19 pandemic in relation to any

of the above,

and which falls in one of the following categories:

i. (sharing information regarding ongoing operation) sharing of information

related to the ongoing availability, performance and/or operation of AEMO Industry

Participant facilities and any risks to ongoing availability, performance and/or

operation

ii. (co-ordinating repairs and maintenance) planning for and/or minimising any

disruptions to energy supply, for example, by coordinating scheduling of any

repairs, maintenance and other works requiring outages

iii. (sharing essential personnel) sharing information and/or entering into common

arrangements in relation to essential employees and contractors to ensure there

are sufficient personnel to maintain and operate energy infrastructure

iv. (sharing essential inputs) sharing information about the availability of, and/or

entering into arrangements to share, essential inputs for energy production,

generation, transmission, distribution and supply systems and infrastructure, such

as parts, equipment or specialised resources necessary for essential maintenance,

as well as other consumable materials necessary for the operation of AEMO

Industry Participant facilities (but in all cases excluding fuel for thermal generators),

and is limited to:

 discussions, conduct, contracts, arrangements and/or understandings to which

AEMO is either a party or has facilitated; or

 discussions, conduct, contracts, arrangements and/or understandings to which

AEMO is not a party but which are carried out for the purposes of implementing a

discussion, conduct, contract, arrangement and/or understanding that AEMO has

facilitated.

1.6. The application further specifies that:

a) where discussions relate to a specific state or territory jurisdiction, discussions will

only occur where attended by a senior officer of the relevant state or territory

government department with responsibility for energy, or their delegate,

b) where conduct, contracts, arrangements and/or understandings relate to a specific

state or territory jurisdiction, conduct, contracts, arrangements and/or

understandings must be agreed to by, or arise out of a discussion attended by, a

senior officer of the relevant state or territory government department with

responsibility for energy, or their delegate.

1.7. Finally, authorisation is not sought for, and the conduct does not include, entering into

any contracts, arrangements or understandings regarding the wholesale or retail price

of energy; or sharing confidential information relating to retail pricing matters, cost or

profits.

1.8. The conduct as described in paragraphs 1.5 to 1.7 is referred to in this determination

as the Proposed Conduct.

2. Background

2.1. AEMO submits that the COVID-19 pandemic could have the potential to impact the

reliability and security of Australian energy systems and markets. In particular:

a) essential workers and contractors who perform regular maintenance and repairs

of critical infrastructure may become unwell with the virus or otherwise be required

to self-isolate;

b) disruption to local and global supply chains as a result of the COVID-19 pandemic

may result in shortages of parts, equipment, fuel or other essential resources that

are necessary to produce and supply energy; and/or

c) lock downs of cities and regional centres are leading to significant changes in

demand patterns, which, without close management can have implications for

system stability from a technical perspective.

2.2. AEMO is concerned that any disruption to the security of Australia’s energy systems

could have significant consequences for consumers, businesses and the Australian

economy.

2.3. AEMO originally applied for authorisation for a broader range of conduct, including

sharing information, entering into arrangements on deferring non-essential works, gas

availability, managing system stability, and any other conduct AEMO deems necessary

as notified to the ACCC. Subsets of this wider range of conduct were permitted in the

interim authorisations of 3 April 2020 and 17 April 2020.

2.4. On 19 June 2020, the ACCC sought information from AEMO as to the ongoing need

for the authorisation, in the context of the COVID-19 pandemic in Australia appearing

to be improving compared to when the application was lodged. On 16 July 2020

AEMO confirmed that, while there was an ongoing need for authorisation, it is

appropriate for the Proposed Conduct to be narrowed to reflect AEMO's better

understanding of the impact of the COVID-19 pandemic in Australia since the

application was first lodged in March 2020. The Proposed Conduct set out in section 1

above reflects the narrowed conduct AEMO provided on 16 July 2020.

AEMO’s role in the energy market

2.5. AEMO’s role is to oversee the operations and security of the NEM power system in

eastern and south-eastern Australia and the Wholesale Energy Market (WEM) in

Western Australia. AEMO also manages a variety of gas trading markets and

infrastructure.

2.6. AEMO’s functions seek to promote the efficient investment in, and efficient use of, gas

and electricity for the long-term interests of Australian consumers in relation to price,

quality, safety, reliability and security.

2.7. AEMO’s responsibilities include monitoring supply and demand, voltage and frequency

and managing planned and unplanned outages and emergencies. AEMO manages the

Gas Short Term Trading Market, the Gas Supply Hubs and Pipeline Capacity Trading,

as well as retail markets in electricity and gas. To achieve this, AEMO monitors system

performance and security and manages the essential services that support a secure

electricity system, such as regulating balancing, frequency control, inertia and system

strength, voltage management and system restart capabilities.

2.8. Forecasting and modelling of potential (or developing) changes is critical to AEMO’s

work. AEMO produces short-term, long-term and operational predictions of demand

and supply, and provides information to market participants about forecast risks to

supply. AEMO also assesses and plans for the impact that operational changes will

have on the system, such as planned outages, the connection of new generators and

gas supply levels.

2.9. If an energy-related event or emergency were to occur, AEMO is responsible for

restoring energy systems to a secure operating state as soon as is safely possible.

AEMO are also responsible for coordination and management of emergency

arrangements across the NEM, WEM and gas markets in eastern and south-eastern

Australia, including collaborating with governments, emergency services and energy

industry participants during major disruptions of energy supply.

3. Consultation

Submissions before the draft determination

3.1. A public consultation process informs the ACCC’s assessment of the likely public

benefits and detriments from the Proposed Conduct.

3.2. The ACCC invited submissions from a range of potentially interested parties including

major energy suppliers, customers, industry associations, consumer groups, state and

federal government agencies and relevant regulatory bodies.

3.3. The ACCC received four submissions from interested parties in relation to the

application. These submissions were from the Public Interest Advocacy Centre (PIAC),

ATCO, the Australian Energy Council, and the Consumers’ Federation of Australia.

3.4. The submissions generally support the granting of authorisation. However, some

parties note that the ACCC should be cautious of authorising the Proposed Conduct

for the requested 12 months due to the success Australia has had in managing the

COVID-19 pandemic and suggested authorisation only continue for six months. Some

interested parties also suggested that authorisation should only be provided for the

conduct permitted by the 17 April 2020 interim authorisation.

3.5. As noted at paragraph 2.4, AEMO amended the application for authorisation to narrow

the forms of cooperation for which it is seeking authorisation to what is now the

Proposed Conduct, after interested party submissions had been provided.

3.6. Public submissions by AEMO and interested parties are on the Public Register for this

matter.

Submissions after the draft determination

3.7. On 24 July 2020, the ACCC issued a draft determination proposing to grant

authorisation until 31 March 2021. A pre-decision conference was not requested

following the draft determination.

3.8. The ACCC received two submissions from interested parties in relation to the draft

determination. These submissions were from the PIAC and Stanwell and support

authorisation, providing comments as to how long they consider authorisation should

operate. The submissions from the PIAC and Stanwell regarding the length of

authorisation are summarised at 4.48, below. PIAC also submits that any cost savings

realised by participating businesses should be passed on to consumers.

3.9. AEMO also provided a submission responding to the draft determination in which it

requests that authorisation extend to 31 May 2021 and confirms that it is content not to

maintain its request for a 12 month period of authorisation at this stage. AEMO’s

submissions regarding the length of authorisation are summarised at 4.48, below.

4. ACCC assessment

4.1. The ACCC’s assessment of the Proposed Conduct is carried out in accordance with

the relevant authorisation test contained in the Act.

4.2. AEMO seeks authorisation for Proposed Conduct that would or might constitute a

cartel provision within the meaning of Division 1 of Part IV of the Act and may

substantially lessen competition within the meaning of section 45 of the Act. Consistent

with subsection 90(7) and 90(8) of the Act, the ACCC must not grant authorisation

unless it is satisfied, in all the circumstances, that the conduct would result or be likely

to result in a benefit to the public, and the benefit would outweigh the detriment to the

public that would be likely to result (authorisation test).

Relevant areas of Competition

4.3. To assess the likely effect of the Proposed Conduct, the ACCC identifies the relevant

areas of competition likely to be impacted.

4.4. AEMO submits that the Participants compete in relation to the generation,

transmission, transportation and/or supply of electricity and gas in Australia.

4.5. The ACCC agrees that the relevant areas of competition are likely to be, separately,

the generation, transmission, and supply of electricity in Australia; and the extraction,

transportation and supply of gas in Australia. Input markets to these supply chains,

including for services such as maintenance, are also likely to be relevant to the

Proposed Conduct.

Future with and without the Proposed Conduct

4.6. In applying the authorisation test, the ACCC compares the likely future with the

Proposed Conduct that is the subject of the authorisation to the likely future in which

the Proposed Conduct does not occur.

4.7. AEMO submits that in the future without the Proposed Conduct, Participants may be

unable to coordinate certain activities in order to ensure the safe, secure and reliable

supply of energy during the COVID-19 pandemic. AEMO further notes that although it

has certain emergency powers to deal with immediate threats to power system

security and interruptions to supply, the existing emergency management

arrangements may not be well suited to dealing with the needs of the current

pandemic situation. AEMO submits that without authorisation its powers to intervene

would not permit it and industry participants to pro-actively plan and coordinate their

maintenance activities to minimise the risk of outages, unless there is an imminent

threat to system security.

4.8. The ACCC considers that in the future without the Proposed Conduct, any COVID-19

related issues that arise in the energy system and that fall within the scope of the

Proposed Conduct, would be managed to the best of AEMO’s ability using its existing

powers. AEMO may also liaise and negotiate with individual industry participants on a

bilateral basis in order to achieve some degree of coordination, but any forward

scheduling of maintenance could only be undertaken in response to an imminent

threat to system security.

4.9. In the future with the Proposed Conduct, AEMO and industry participants will be able

to coordinate to mitigate or resolve COVID-19 related issues in the energy system that

fall within the scope of the Proposed Conduct. This coordination is beyond AEMO’s

existing powers and so will better allow a collective response to COVID-19 related

issues in the system.

Public benefits

4.10. The Act does not define what constitutes a public benefit. The ACCC adopts a broad

approach. This is consistent with the Australian Competition Tribunal (the Tribunal)

which has stated that the term should be given its widest possible meaning, and

includes:

…anything of value to the community generally, any contribution to the aims pursued

by society including as one of its principal elements … the achievement of the

economic goals of efficiency and progress.

4.11. The ACCC has considered the following public benefits:

 greater capacity to ensure the ongoing safety, security and/or reliability of

Australian energy systems

 minimising costly delays to maintenance.

Greater capacity to ensure the ongoing safety, security and/or reliability of

Australian energy systems

4.12. AEMO submits that the Proposed Conduct will help ensure the ongoing safety,

security, and/or reliability of Australian energy systems and the integrity of wholesale

markets during the COVID-19 pandemic. The supply of gas and electricity to

consumers is essential, and disruptions to these services during the COVID-19

pandemic can have significant detrimental impacts for consumers, businesses and the

economy.

4.13. AEMO considers the Proposed Conduct will improve the information available to it

regarding the ongoing availability, performance and operation of energy industry

participants, help to minimise any disruptions to energy supply (for example, by

coordinating the scheduling of any repairs, maintenance and other works requiring

outages) and improve its management of system stability.

4.14. AEMO submits that disruptions to energy supply could occur as a result of three

factors:

a) essential workers or contractors responsible for maintenance or repairs becoming

unwell and/or being required to self-isolate as a result of COVID-19

b) possible shortages in parts, equipment or other essential resources as a result of

disruptions to local and global supply chains, and/or

c) ongoing changes in demand for energy as a result of changed economic activity

and lock-downs of cities and regional centres, which may have implications for

system stability from a technical perspective.

4.15. AEMO also submits that the effects of the COVID-19 pandemic, including border

restrictions and quarantine requirements, are likely to continue into spring and

summer. AEMO notes that several energy participants have deferred their essential

works to begin after March 2021 and considers that there is a material risk of power

outages if these maintenance activities are not managed.

4.16. The ACCC considers that the Proposed Conduct will improve the ability for the

Participants to respond to impacts of the COVID-19 pandemic on Australia's energy

systems and markets. Should such impacts occur, AEMO will be able to convene

relevant groups to quickly share critical information and, where necessary, collectively

agree to specific responses. Such collective action is unlikely to be achieved absent

the authorisation, or is unlikely to be achieved quickly as AEMO would need to work

individually with relevant Participants.

Queensland Co-operative Milling Association Ltd (1976) ATPR 40-012 at 17,242; cited with approval in Re 7-Eleven

Stores (1994) ATPR 41-357 at 42,677.

4.17. This enhanced capacity to respond to impacts of the pandemic reduces the potential

for the COVID-19 pandemic to give rise to outages or other system security issues.

Improvements to system security, safety and reliability flow onto economic benefits by

avoiding outages for consumers and producers, and minimising damage to energy

system infrastructure through system instability.

4.18. The ACCC therefore considers that the Proposed Conduct is likely to result in a public

benefit in the form of providing greater capacity to ensure the ongoing safety, security

and/or reliability of Australian energy systems.

Minimising costly delays to maintenance

4.19. Travel restrictions, border closures, and other impacts on production are likely to

impact on critical maintenance activities in the energy system. Maintenance at facilities

such as thermal generators can involve significant temporary workforces and highly

specialised foreign labour. These workforces may not be available, or may be

significantly restricted in their movements during the COVID-19 pandemic. Core

components are often imported from specialised manufacturers, and these supply

chains may be disrupted due to COVID-19.

4.20. The COVID-19 pandemic is likely to make maintenance activities more difficult to plan

for, and has the potential to cause delays and extended outages at specific

generators. Such delays or outages at specific generators would impose costs to those

generators. These costs will likely be passed through to consumers.

4.21. The Proposed Conduct is likely to reduce the potential for COVID-19 to cause delays

or extended outages at specific generators. Participants should be able to coordinate a

maintenance schedule that minimises the potential for delays to cascade and create

overlapping, expensive outages. Sharing information will better allow Participants to

find relevant labour and components in the unique COVID-19 circumstances.

4.22. While in normal market conditions, the ACCC would generally take the view that

competition between generators is likely to be superior in allocating maintenance

labour and components, the COVID-19 pandemic may cause acute supply issues to

such markets, such as forcing large teams of skilled labour to quarantine, or become

sick, for extended periods of time. Given the potentially high cost of delays to

maintenance, the ACCC considers that there is public benefit in minimising these costs

during the pandemic.

4.23. AEMO and relevant Participants in Queensland and Victoria have been coordinating

maintenance under the interim authorisation. Such activities reflect that there have

been some COVID-19 related disruptions to maintenance plans.

4.24. An example of this public benefit during the interim authorisation (provided by AEMO)

was when, through discussions held under the interim authorisation, one generator

was able to quickly locate an alternative local supplier of a major part that would

ordinarily be imported from Germany but was unavailable for importation due to

COVID-19 pandemic related restrictions in Europe. This avoided an extended outage

which was at risk of overlapping with other scheduled outages in the state, giving rise

to risks of energy outages. The sharing of this information (which does not ordinarily

occur, even through AEMO) caused other generators to consider their supply chains

for their outages earlier than originally planned, to avoid the risk of delays for their

outages.

4.25. The ACCC considers that the Proposed Conduct is likely to result in a public benefit in

the form of minimising costly delays to maintenance.

ACCC conclusion on public benefit

4.26. The ACCC considers that the Proposed Conduct is likely to result in public benefits

from providing greater capacity to ensure the ongoing safety, security and/or reliability

of Australian energy systems, and from minimising costly delays to maintenance.

Public detriments

4.27. The Act does not define what constitutes a public detriment. The ACCC adopts a

broad approach. This is consistent with the Tribunal which has defined it as:

…any impairment to the community generally, any harm or damage to the aims

pursued by the society including as one of its principal elements the achievement of

the goal of economic efficiency.

4.28. The ACCC has considered the following public detriments:

 reduced competition in wholesale electricity markets

 reduced competition for maintenance services and other inputs.

Reduced competition in wholesale electricity markets

4.29. The ACCC considers that sharing commercially sensitive information regarding

ongoing operations of facilities, including generators, could lessen competition in

wholesale electricity markets.

4.30. The transparency afforded to Participants over the operations of their competitors

could facilitate anti-competitive and inefficient behaviours. For example, the bidding

behaviour of generators may change if they learn through the Proposed Conduct that a

particular competitor’s plant is suffering technical issues.

4.31. Such detriments may be increased through information asymmetries. Because the

information that is shared under the Proposed Conduct may not otherwise be publicly

available, Participants may be able to use market sensitive information to their

advantage and to the disadvantage of non-participants. Where some businesses have

access to more or better information than their rivals the resulting information

asymmetry can act as a barrier to competition for the less informed business and have

a distortionary effect on the market. For example, customers and aggregators on the

demand-side may be less well informed about the precise details of planned plant

outages than the generators involved in the Proposed Conduct. The result could be

that businesses on the demand-side have less opportunity to anticipate and respond to

strategic behaviour than the involved generators.

4.32. However, the ACCC considers that the risk of a lessening of competition occurring in

wholesale electricity markets is limited for two reasons:

4.33. The Proposed Conduct does not involve entering into any contracts, arrangements or

understandings regarding the wholesale price of energy; and

4.34. In relation to the concerns regarding asymmetric information, the Australian Energy

Market Commission recently made a change to the National Electricity Rules to

increase the transparency of information made available to Participants via the

medium-term projected assessment of system adequacy (MTPASA) process.

The

Re 7-Eleven Stores (1994) ATPR 41-357 at 42,683.

Australian Energy Market Commission, Rule Determination, National Electricity Amendment (Improving Transparency and

Extending Duration of MTPASA) Rule 2020, 20 February 2020, available at:

new Rule provides for the publication of generator availability information at the

individual participant and plant unit level. This would substantially reduce the degree of

information asymmetry concerning planned outages between parties involved in the

Proposed Conduct and those not involved. The new Rule took effect on 20 August

2020.

4.35. Potential risk is also limited by the Proposed Conduct stipulating that Participants are

not able to conduct discussions or form agreements without the oversight of AEMO

and a senior officer of the relevant state or territory government department with

responsibility for energy (or their delegate) in attendance.

4.36. The ACCC considers that the Proposed Conduct may lead to detriments by reducing

competition in wholesale electricity markets, but that such detriments are unlikely and

would not persist long-term.

Reduced competition for maintenance services and other inputs

4.37. By allowing the Participants to coordinate their repairs and maintenance, the Proposed

Conduct is likely to reduce competition for the supply of maintenance services.

4.38. A coordinated approach to maintenance may be less efficient in allocating service

providers to the most valuable maintenance work, and may impact service provider

revenue. Coordination may have similar impacts on markets for other inputs, such as

components or non-maintenance related personnel.

4.39. The ACCC considers that the Proposed Conduct is likely to lessen competition for

maintenance services and other inputs. However, as discussed previously, given the

unique circumstances of the COVID-19 pandemic, the ACCC considers that

coordination to minimise disruption to the system, or costly delays to generators is

likely to give rise to public benefits.

ACCC conclusion on public detriment

4.40. The ACCC considers that the Proposed Conduct is likely to lead to some public

detriment as a result of a lessening of competition in wholesale markets and for

maintenance services and other inputs.

Balance of public benefit and detriment

4.41. The ACCC considers that the Proposed Conduct is likely to result in public benefits in

the form of greater capacity to ensure the ongoing safety, security, and/or reliability of

Australian energy systems, and minimise costly delays to maintenance.

4.42. The ACCC considers that the Proposed Conduct is likely to lead to some public

detriment as a result of a lessening of competition in wholesale markets and for

maintenance services and other inputs. However, the ACCC considers that the

detriment resulting from coordination in respect of these services is offset by the public

benefit that such coordination brings by reducing disruption to the system and costly

delays to generators.

4.43. For the reasons outlined in this determination, and subject to the conditions, the ACCC

is satisfied that the Proposed Conduct is likely to result in a public benefit and that this

public benefit would outweigh any likely detriment to the public from the Proposed

Conduct.

https://www.aemc.gov.au/sites/default/files/documents/erc0270_-_mt_pasa_final_determination.pdf (accessed 16 July

2020).

Length of authorisation

4.44. The Act allows the ACCC to grant authorisation for a limited period of time.

This

enables the ACCC to be in a position to be satisfied that the likely public benefits will

outweigh the detriments for the period of authorisation. It also enables the ACCC to

review the authorisation, and the public benefits and detriments that have resulted,

after an appropriate period.

4.45. AEMO initially sought authorisation for 12 months from the date of final determination.

This would be until approximately 30 September 2021.

4.46. Before the ACCC issued its draft determination, the PIAC submitted that with

restrictions across Australia being lifted (at the time of its submission) and in the

absence of a severe second wave of infections, the types of disruptions that the

Proposed Conduct seeks to overcome may no longer be material and the ACCC

should consider a six month authorisation period rather than 12. This would be until

approximately 31 March 2021.

4.47. The ACCC’s draft determination, issued on 24 July 2020, proposed to grant conditional

authorisation until 31 March 2021.

4.48. In response to the draft determination PIAC advised that they were supportive of

authorising the Proposed Conduct until 31 March 2021, whereas Stanwell submitted

that in light of the resurgence of COVID-19 in New South Wales and Victoria it

considered it appropriate for authorisation to extend to 30 September 2021.

4.49. AEMO’s submission responding to the draft determination requests that authorisation

extend to 31 May 2021 because:

a) The Stage 3 and Stage 4 lockdowns in Victoria confirm that serious risks remain

for the foreseeable future. And the effects of the COVID-19 pandemic, including

border restrictions and quarantine requirements, are likely to continue into spring

and summer.

b) Restrictions imposed in response to the COVID-19 pandemic have already had a

direct and material impact on the essential maintenance of infrastructure. In

particular:

i) maintenance works have been deferred from the cooler months

ii) border closures and quarantine requirements have impaired the movement of

specialist maintenance personnel

iii) on-site social distancing requirements, delays in receiving parts from

overseas, self-isolation and COVID testing requirements for sick employees

have caused delays and extensions to maintenance works

iv) a heightened risk of extended outages, in turn, increases the risk of outages

overlapping with one another and can give rise to power outages.

c) Energy industry participants have deferred essential works as a result of the

COVID-19 pandemic and AEMO has been able to facilitate discussions and

cooperation allowing for the re-scheduling of these works. However, the extended

summer period of high demand and extreme stress on the energy system is

approaching, which will bring a heightened risk of breakdowns and power

outages.

Subsection 91(1)

d) Many maintenance outages that would ordinarily have occurred by now have been

postponed to the first feasible opportunity in 2021 – the post-summer period

beginning after March 2021. AEMO considers there is a material risk of power

outages if this concentration of outages is not managed in a manner similar to that

undertaken under the interim authorisation to date.

e) Without authorisation, AEMO’s powers to intervene in relation to maintenance

(including by directing that maintenance be rescheduled) is limited to

circumstances where there is an imminent threat to system security and is unlikely

to be triggered where AEMO and industry wish to pro-actively plan and coordinate

their maintenance activities to minimise the risk of outages.

f) There has been a material change in circumstances since submissions on the

Application were made in May 2020, with restrictions responding to the COVID-19

pandemic continuing to intensify.

4.50. The ACCC considers that COVID-19 related authorisations should only be in place so

long as they are necessary. However, in light of recent outbreaks of COVID-19 in

Australia and AEMO’s observation that there is currently concentration of scheduled

maintenance activities from March 2021, the ACCC considers that a longer period of

authorisation is appropriate.

4.51. The ACCC accordingly grants authorisation until 31 May 2021.

5. Determination

The application

5.1. On 30 March 2020, AEMO lodged application AA1000484 with the ACCC, seeking

authorisation under subsection 88(1) of the Act. AEMO amended its application for

authorisation on 16 July 2020.

The authorisation test

5.2. Under subsections 90(7) and 90(8) of the Act, the ACCC must not grant authorisation

unless it is satisfied in all the circumstances that the Proposed Conduct is likely to

result in a benefit to the public and the benefit would outweigh the detriment to the

public that would be likely to result from the Proposed Conduct.

5.3. For the reasons outlined in this determination and subject to the conditions below, the

ACCC is satisfied, in all the circumstances, that the Proposed Conduct would be likely

to result in a benefit to the public and the benefit to the public would outweigh the

detriment to the public that would result or be likely to result from the Proposed

Conduct, including any lessening of competition.

5.4. Accordingly, subject to the conditions, the ACCC grants authorisation.

Conditions of authorisation

5.5. In its interim authorisations of 3 April, 17 April, and 24 July 2020 the ACCC imposed

conditions that, in broad terms, required AEMO to regularly report to the ACCC how

authorisation is being used, Participants to continue to comply with conditions imposed

in related authorisations, and any agreements formed in reliance of the interim

authorisation not to endure beyond the authorisation period.

5.6. The ACCC has also added a condition that would allow additional parties to be

approved as ‘Other Approved Participants’ during the authorisation.

5.7. These conditions provide important transparency in relation to the conduct being

undertaken under the interim authorisation, ensure that other (related) authorisations

are not compromised and signal to Participants how appropriate agreements and

arrangements should be structured. The ACCC considers that these mechanisms

minimise the risk and extent of detriment, discussed above, and therefore has decided

to retain conditions to this effect in the authorisation.

5.8. The ACCC grants authorisation subject to the following conditions:

Condition 1: Reporting Requirements

5.9. AEMO must comply with the attached Reporting and Communications Protocol

(Attachment A).

Condition 2(a): WA and NT LNG producers

5.10. Where the Proposed Conduct involves the scheduling of maintenance at LNG facilities

in WA or the NT, Disclosing Producers (as defined in Attachment B) must comply with

Attachment B.

Condition 2(b): Queensland LNG producers

5.11. Where the Proposed Conduct involves the scheduling of maintenance at LNG facilities

in Queensland, LNG Producers (as defined in Attachment C) must comply with

Attachment C.

Condition 3: Agreements not to endure beyond authorisation period

5.12. Any contract, arrangement or understanding entered into in reliance on this

authorisation must provide for its immediate termination (other than any provisions

dealing with ongoing confidentiality obligations) upon the expiry or revocation of this

authorisation.

Condition 4: Approval process for Other Approved Participants

5.13. The following process applies to any party (other than AEMO and AEMO Industry

Participants) that wishes to obtain the protection of this conditional authorisation:

a) AEMO must seek the approval of the ACCC by sending an email to

adjudication@accc.gov.au, identifying the proposed party, including a description

as to the conduct of that party, and (other than in respect of parties who have

newly been registered or received an exemption in respect of an electricity or gas

market or system operated or managed by AEMO) the reasons why such

participation is desirable to achieve the purposes of the Proposed Conduct (set

out in paragraphs 1.5 to 1.7 of this determination).

b) If the ACCC approves the party to engage in some or all of the conduct the

subject of the notification, that party will receive the protection of this conditional

authorisation, subject to any conditions imposed by the ACCC, from the time that

AEMO is notified of the ACCC’s decision.

c) When considering the inclusion of a proposed party, the ACCC may in its absolute

discretion, refuse to approve the inclusion of the proposed party or impose

conditions which restrict the type or extent of the Proposed Conduct in relation to

the proposed party.

d) Unless the ACCC approves the party, it will not have any protection under this

conditional authorisation.

5.14. The ACCC may authorise a Committee or Division of the ACCC, a member of the

ACCC or a member of the ACCC staff, to exercise a decision making function under

the conditions of this authorisation on its behalf.

Conduct which the ACCC has decided to authorise

5.15. The ACCC grants conditional authorisation AA1000484 to enable the Participants to

cooperate to ensure the ongoing safety, security, or reliability of Australian energy

systems during the COVID-19 pandemic as described in paragraphs 1.5 to 1.8 and

defined as the Proposed Conduct.

5.16. The ACCC grants authorisation in relation to Division 1 of Part IV of the Act and

section 45 of the Act.

5.17. The ACCC has decided to grant authorisation AA1000484 until 31 March 2021.

6. Interim authorisation

6.1. AEMO requested interim authorisation for the Proposed Conduct, along with

cooperating on deferring non-essential works, sharing information on gas availability,

managing system stability, and any other conduct AEMO deems necessary and as

notified to the ACCC.

6.2. On 3 April 2020, the ACCC granted interim authorisation under subsection 91(2) of the

Act for a subset of the conduct. On 17 April 2020, the interim authorisation was

revoked and a new interim authorisation issued to allow the Participants to engage in

all of the conduct proposed by AEMO at that time, with the exception of sharing

information regarding gas availability.

Both of these interim authorisations were

subject to conditions.

6.3. On 16 July, AEMO wrote to the ACCC to narrow the scope of the conduct sought

under authorisation to the Proposed Conduct and requested that the interim

authorisation be varied to reflect the Proposed Conduct.

6.4. On 24 July 2020 the ACCC decided to revoke the 17 April 2020 interim authorisation,

and grant a replacement conditional interim authorisation under subsection 91(2) of

the Act to allow the Participants to engage in the Proposed Conduct. The interim

authorisation was subject to conditions substantively similar to those described at

paragraphs 5.9 to 5.12 of this Determination.

6.5. Interim authorisation will remain in place until the ACCC’s final determination comes

into effect or until the ACCC decides to revoke interim authorisation.

7. Date authorisation comes into effect

7.1. This determination is made on 17 September 2020. If no application for review of the

determination is made to the Australian Competition Tribunal it will come into force on

9 October 2020.

See ACCC Interim Authorisation Decision of 17 April 2020 available at https://www.accc.gov.au/system/files/public-
