Nexa Advisory submits the attached rule change request to maintain a robust and effective regulatory environment amid the rapid transformation of the energy market. We are proposing a significant and necessary reform to the ring-fencing framework, designed to directly address existing deficiencies and emerging competitive challenges within the contestable energy services markets.
Since the rise in the take up of solar rooftop in Australia by consumers, the consumer energy market has been contested by incumbent networks. As a result, the protections delivered by the Australian Energy Regulator (AER) Ring-fencing Guideline (Guidelines) have been progressively weakened – most visibly through the expansion and normalisation of waivers that permit DNSP participation in contestable markets without sufficiently robust conditions, monitoring, or transparency. This creates material risks for competitive neutrality and consumer outcomes at precisely the time these markets are becoming central to the energy transition.
Nexa’s efforts are driven by three core objectives: to bolster consumer protections, stimulate greater competition and expertly manage the integration of distributed energy resources and new technologies. We note the proposed rule change is supported by key organisations and member associations across the industry including the Smart Energy Council, the Clean Energy Council, the Australian Energy Council, Solar Citizens, National Electrical and Communications Associations and many other organisations.
The proposed changes are intended to protect long term interests of consumers by enhancing the competitive consumer energy market- resources and services. This is by formally incorporating the Guidelines into the National Electricity Rules (NER). Secondly, introduce five targeted amendments that strengthen the current Guidelines:
- Market benefit and consumer failure test – direct competition by Distribution Network Service Providers (DNSPs) in contestable markets will be permitted only under significantly tightened waiver conditions. Entry must be strictly limited to instances of demonstrated market failure, where the contestable market cannot supply the required service, and where the DNSP’s involvement guarantees measurable, long-term benefits for consumers.
- Financial resilience and ring-fence triggers – to prevent DNSPs from jeopardising their own financial stability or credit standing and supporting affiliated enterprises, we are establishing mandatory minimum financial requirements. These stipulations mandate the maintenance of an investment-grade credit rating and adherence to specific minimum liquidity ratios.
- Affiliate Dealings and data access – the anti-discrimination rules governing DNSP interactions with their affiliated business units are being strengthened. This is intended to mitigate the risk of DNSPs unfairly favouring their own entities in contestable markets. Breaches of these obligations will be subject to enforceable penalties under the Australian Energy Regulator’s (AER) compliance framework.
- Branding and representation – new rules are proposed to prevent consumer confusion and the conferral of an unfair market advantage. This includes prohibiting shared branding and ambiguous messaging. Consumers must be given explicit assurance that they are under no obligation to purchase contestable services (such as Distributed Energy Resources (DER) or EV charging) from a DNSP or its associated businesses.
- Reporting, complaints and enforcement transparency – codify a minimum transparency architecture so ring-fencing oversight is observable and auditable through a standardised annual AER compliance/enforcement report (including waivers, investigations and outcomes) and a safe, formalised pathway for stakeholders to raise ring-fencing concerns, supported by consistent triage and complaint publication expectations.
This rule change request is deliberately narrow. We recognise the AEMC’s forward work program includes an upcoming network regulation review, and we consider a number of broader issues to be best examined through that review – rather than as part of this proposal. This may include issues around economic/regulatory incentives (including the capital expenditure bias and consideration of alternative regulatory models like totex), connection process performance, tariff/pricing settings and related data reforms. In that sense, this rule change is intended to establish a targeted, near-term reform pathway, while the network regulation review will consider the wider reform package needed to ensure distribution regulation remains fit-for-purpose.
