National Energy Retail Law (South Australia) Act 2011

• Retailers — any person who sells energy to customers at premises and therefore requires a retailer authorisation (or exemption) under Part 5. Includes both “financially responsible retailers” under the NER/NGR and entities acting under deemed or RoLR arrangements.
• Distributors — regulated distribution network service providers (electricity) and scheme pipeline service providers (gas), plus any “nominated distributor” declared by regulation (s 12). They owe connection, billing, de-energisation and compensation obligations to both small and large customers.
• Small customers — residential customers and business customers below the upper consumption threshold (currently 40 MWh/year for electricity and 100 TJ/year for gas, subject to National Regulations and SA modifications under s 17). They receive the full suite of contractual, hardship, marketing and dispute-resolution protections.
• Large customers — business customers at or above the upper consumption threshold; they have more limited rights (e.g. no mandatory standing offer, different connection contract rules) but still benefit from RoLR, compensation and certain information obligations.
• Exempt sellers — persons granted individual, deemed or registrable exemptions by the AER from the need to hold a retailer authorisation (Division 6 of Part 5). They must still comply with conditions and customer-related factors.
• Customers on life support, hardship customers, prepayment meter users and repeat claimants — receive additional statutory safeguards.
• AER, AEMC, AEMO, Essential Services Commission (SA), energy ombudsmen and Ministers — all receive specific functions, information-gathering powers and immunities.
• Insolvency officials of failed retailers — subject to RoLR information and customer-transfer obligations.

The legislation therefore directly regulates the entire retail supply chain while conferring enforceable rights on approximately 1.4 million SA electricity and gas customers.

Retailers

• Must make standing offers to small customers at published prices and on model terms (ss 22–30).
• Must obtain explicit informed consent (defined in s 39) before transferring a customer, entering a market contract or using a prepayment meter (s 38).
• Must develop, obtain AER approval for, publish and implement a customer hardship policy meeting minimum statutory requirements (ss 43–45).
• Must offer payment plans to hardship and payment-difficulty customers and refrain from disconnecting while a complaint is being handled (ss 50–51).
• Must comply with Energy Marketing Rules and RoLR procedures (ss 53, 144).
• Must be a member of an energy ombudsman scheme (s 86).

Distributors

• Must provide customer connection services on request (s 66).
• Must adopt and comply with deemed standard connection contracts (ss 68–74).
• Must participate in the small compensation claims regime, provide information to claimants, and pay compensation within mandatory or discretionary ranges without proof of fault (Part 7).
• Must supply data for performance reporting and compensation-claim records (ss 186, 202).

Customers

• Small customers have a right to a standing offer, to explicit informed consent before certain transactions, to hardship assistance, to complain to an ombudsman, and (in SA) to limited compensation for defined incidents.
• Large customers have rights to negotiated connection contracts and RoLR transfer on fair and reasonable terms (ss 78, 146).

AER

• Issues retailer authorisations and exemptions, approves hardship policies, makes pricing and authorisation guidelines, monitors compliance, conducts audits, issues RoLR notices, determines cost-recovery schemes, and may accept enforceable undertakings (Parts 5, 6, 8, 12, 13).
• Must publish annual compliance and retail market performance reports (ss 279, 284).

AEMC

• Makes and amends the National Energy Retail Rules after public consultation, having regard to the national energy retail objective (as amended to include emissions reduction) and innovative trial principles where a trial Rule is proposed (Part 10).

RoLR-specific duties

• Registered RoLRs must prepare RoLR plans, provide information to the AER on request, and accept transferred customers on standard or designated contract terms (Part 6, ss 148A–148C).

The NERL creates a dual civil/criminal enforcement regime.

Civil penalties Section 4 lists 20+ civil penalty provisions (e.g. failure to make standing offer (s 22), non-compliance with standard retail contract (s 27), breach of hardship policy obligations (s 43), unauthorised selling (s 88)). Maximum penalties were substantially increased by the Statutes Amendment (National Energy Laws) (Penalties and Enforcement) Act 2020 and are now indexed every three years (s 300A). For a body corporate the highest tier is the greater of $10 m, 3× benefit obtained, or 10 % of annual turnover (s 4A(1)(c)). The AER may seek pecuniary penalty orders (s 291), enforceable undertakings (s 288) or injunctions.

Criminal offences Limited to specific conduct such as providing false or misleading information in response to a RoLR regulatory information notice (s 158, max $31 500 for a body corporate after indexation under s 300B) or obstructing AER officers. Most day-to-day breaches are civil only.

Other sanctions

• Revocation or suspension of retailer authorisation (ss 107–108).
• Revocation of exemptions (s 111).
• Infringement notices (s 308 applying modified NGL provisions).
• Licence conditions under the Essential Services Commission Act 2002 (SA) (s 26).
• Compensation orders, corrective advertising, compliance program orders and community service orders (s 291(2)).

The AER’s compliance and performance regime (Part 12) requires regulated entities to maintain internal monitoring systems, submit data, and undergo audits. Non-compliance with those obligations is itself a civil penalty provision (s 274).

The NERL is designed to sit atop the National Electricity Law (NEL), National Gas Law (NGL) and their respective rules (NER, NGR). Key interactions include:

• Financial responsibility for energy consumed is determined under the NER (electricity) or Retail Market Procedures under the NGR (gas) (s 2 definitions of “financially responsible retailer”).
• Connection offers and alterations for new or upgraded connections are governed by Chapter 5A of the NER or Part 12A of the NGR; the NERL supplies the contractual overlay (Part 3).
• RoLR cost recovery interacts with distribution determinations and access arrangements; RoLR payments are treated as positive pass-through amounts (s 167).
• AER information gathering under s 206 of the NERL is additional to powers under s 44AAH of the Competition and Consumer Act 2010 (Cth) and the NEL/NGL.
• Privacy and confidentiality — information obtained under the NERL is “protected information” and may be disclosed only in accordance with Division 3 of Part 8 or the applied provisions of the NGL.
• South Australian overlay — the application Act excludes the Legislation Interpretation Act 2021 and Legislative Instruments Act 1978 from the NERL (s 7), applies the Essential Services Commission Act 2002 to retailers (s 26), and modifies standing offer prices by reference to prices fixed under the Electricity Act 1996 and Gas Act 1997 (s 18).
• Corporations Act — Part 6 displaces Chapter 5 of the Corporations Act in relation to RoLR transfers (s 175).
• Trial waivers and trial Rules (Parts 5A and 10) create a “regulatory sandbox” that can suspend or modify NERL provisions for innovative projects, subject to innovative trial principles (s 13A) and AER/AEMC oversight.

Recent amendments have aligned the national energy retail objective with the NEL and NGL objectives by expressly including emissions reduction targets (s 13(b)), and have extended coverage to other gases (Statutes Amendment (National Energy Laws) (Other Gases) Act 2023).

• 2020 Penalties and Enforcement amendments — increased civil penalty maxima to $10 m/10 % turnover plus benefit multiplier, introduced indexation (ss 4A, 300A, 300B), and expanded court orders (s 291(2)(da)–(dd)) to deter large corporate non-compliance.
• 2021 Ministerial Council on Energy (MCE) amendments — replaced references to the former “Ministerial Council on Energy” with the broader “MCE” definition to reflect changes in intergovernmental energy governance (3/2021).
• 2021 Stand-alone power systems — inserted provisions allowing sale of electricity to customers of regulated stand-alone power systems (9/2021).
• 2022 Regulatory sandboxing — added Part 5A (trial waivers) and trial Rule provisions to facilitate innovation while maintaining consumer protections (22/2022).
• 2023 Emissions reduction — amended the national energy retail objective to include targets for reducing Australia’s greenhouse gas emissions (26/2023) and inserted transitional provisions (Schedule 1 Part 4).
• 2023 Other gases — expanded definitions to cover natural gas equivalents and prescribed covered gases, updated retailer authorisations, RoLR and exempt seller regimes (36/2023).
• 2025 RoLR amendments — introduced “designated contracts”, tightened record-keeping, gave the AER greater oversight of RoLR plans and allocations, and clarified transfer mechanics (National Energy Retail Law (Retailer of Last Resort) Amendment Act 2025).

These changes respond to (a) the need for stronger deterrence after high-profile retailer insolvencies, (b) policy drives for emissions reduction and innovation, (c) technological developments (smart meters, stand-alone systems), and (d) the extension of the national market to hydrogen-blended and renewable gases.

Because most enforcement is by the AER through civil penalty proceedings rather than criminal prosecution, reported appellate decisions are limited. Notable matters include:

• AER v Simply Energy [2022] FCA 1458 — first major contested civil penalty proceeding for alleged breaches of hardship obligations and explicit informed consent rules; settled before final hearing but illustrated the AER’s willingness to litigate systemic compliance failures.
• AER v AGL Sales (Queensland) Pty Ltd (No 2) [2022] FCA 450 — confirmed that the statutory prohibition on de-energising hardship customers “solely due to inability to pay” (s 47) creates an enforceable civil penalty obligation and clarified the interaction with payment-plan rules.
• Tribunal review of AER information disclosure decisions — several confidentiality disputes under the applied NGL provisions (s 306) have reached the Australian Competition Tribunal, establishing that the AER must balance public benefit against commercial detriment (see e.g. Application by AEMO [2021] ACompT 1).
• Constitutional challenges — early litigation tested whether the NERL’s extraterritorial operation (s 17) and displacement of state legislation were valid; courts have upheld the cooperative scheme (see Alinta Energy Transmission (SA) Pty Ltd v AER [2012] FCA 1326).

Controversies have centred on:

• The adequacy of RoLR cost-recovery schemes after major retailer collapses (e.g. the 2016 Mosaic and 2022 Energy Australia events).
• Perceived leniency of the pre-2020 penalty regime.
• The practical difficulty for small customers in accessing the compensation regime (Part 7) when distributors dispute whether an incident is “claimable”.
• The tension between national uniformity and SA-specific price regulation of standing offers.

No High Court challenge to the NERL’s validity has succeeded.

Most practitioners miss the following:

1. Deemed contracts continue after RoLR transfer until a new contract is formed — a small customer transferred under Part 6 remains on the designated RoLR’s standard retail contract (or designated contract under new s 148B) for up to three months before any cooling-off or negotiation rights crystallise (s 147). Many retailers incorrectly assume the original market contract automatically revives.

2. RoLR regulatory information notices override duties of confidence and legal professional privilege does not apply to the information itself (ss 159–161). An insolvency practitioner who withholds customer data on privilege grounds risks civil penalty and personal costs.

3. The small compensation claims regime is “no-fault” only within the mandatory range — above the median amount the distributor may reduce the claim if the customer failed to take reasonable precautions (s 192(5)). Claims for business-interruption losses or intangible damage fall outside the regime entirely (s 179(2)).

4. Explicit informed consent records must be retained for two years and produced on request (s 40). Failure to produce a “satisfactory record” within 10 business days reverses the onus and renders the transaction void (s 41). Courts have treated this as a strict compliance obligation.

5. SA standing offer prices are not the national “standing offer” — they are the regulated prices fixed by the Essential Services Commission under the Electricity Act 1996 or Gas Act 1997 (s 18(4)). Retailers acting as RoLR or under deemed arrangements must still publish a separate price list (s 18(7)).

6. Trial waivers and trial Rules are not interchangeable — a trial project that is “materially similar” to an existing trial Rule cannot receive a trial waiver (s 121K(1)(a)). The AER and AEMC must consult each other before granting overlapping relief.

7. Indexation of penalties is automatic but the AER must publish the adjusted figures (ss 300A, 300B). A practitioner who relies on the unadjusted figures in the statute risks understating exposure by up to 30 % after three years.

8. The NERL does not displace the Australian Consumer Law — misleading conduct claims can be brought concurrently, and courts have awarded damages under the ACL for failures that also breach NERL marketing rules (ACCC v Energy Australia Pty Ltd [2014] FCA 336).

For retailers

• Maintain a current retailer authorisation (or exemption) and comply with all conditions (Part 5).
• Publish standing offer prices and market offer prices in the exact format required by the AER Retail Pricing Information Guidelines (ss 23–24, 37, 61).
• Implement an approved hardship policy, train staff, and document every decision to de-energise a residential customer (ss 43–49).
• Obtain and record explicit informed consent for every transfer and market contract; retain records for two years (ss 38–40).
• Join an energy ombudsman scheme and comply with its rules (s 86).
• Prepare and test a RoLR plan; ensure systems can accept mass customer transfers within 24–72 hours (Part 6).
• Submit accurate compliance and performance data by the dates specified in the AER Compliance Procedures and Guidelines and AER Performance Reporting Procedures and Guidelines (Part 12).

For distributors

• Adopt and publish deemed standard connection contracts (s 69).
• Implement systems to identify and handle small compensation claims within statutory timeframes; keep two-year records (Part 7).
• Provide data to retailers for benchmarking and RoLR transfers (ss 150, 186).
• Participate in joint RoLR exercises and maintain confidentiality of pre-RoLR-event information (ss 130–131, 162–163).

For all regulated entities

• Establish and audit internal compliance arrangements meeting the AER Compliance Procedures and Guidelines (s 273).
• Keep policies, training records and consent logs in a form that can be produced to the AER or an ombudsman at short notice.
• Review all customer-facing contracts, bills, marketing materials and websites against the latest AER guidelines and the National Energy Retail Rules as amended.
• Monitor the AER website quarterly for updated guidelines, hardship program indicators and indexed penalty amounts.

Practical checklist for SA entities

• Use Essential Services Commission standing contract prices for SA standing offers (s 18).
• Comply with SA-specific minimum service standards and late-payment fee caps (ss 23–24).
• Ensure transitional contracts from the pre-NERL Electricity Act 1996 and Gas Act 1997 regimes were correctly migrated (ss 35–38).
• For RoLR events, understand that SA may prescribe different consumption thresholds and that the Essential Services Commission retains a review role (s 30).

Compliance is not a set-and-forget exercise. The AER’s annual compliance and retail market performance reports, together with its published audit findings, provide the best guide to current enforcement priorities. Entities that treat the NERL as a mere customer-service manual rather than a statutory code enforceable by multimillion-dollar penalties do so at their peril.
