Unlocking CER Benefits Rule Change Draft Determination
A new draft determination from the AEMC proposes to introduce two new meter types and new provisions for the establishment of additional settlement points behind NEM connection points for small and large customers. Under the proposed rule change, large customers would be able to choose multiple energy service providers for their premises.

A draft determination provides an opportunity for interested stakeholders to review the rule change and participate in discussions and feedback sessions before the rule is published. This article provides a short overview of the proposed changes in the draft determination, which can be read in full on the AEMC website.

The draft determination proposes rule changes to various metering arrangements to facilitate participation and settlement of newer technologies in the National Electricity Market
Type 8 and Type 9 meters
The first change introduces new kinds of energy meters. Modern smart meters, also known as Type 4 meters, are used for most new residential and business connections to the NEM. In some situations, like streetlights, street furniture, or pole-mounted EV chargers, it is not feasible to attach a typical Type 4 meter to the structure.
The rule change introduces two new meters, Type 8 and Type 9. These meters will still need to fulfil requirements to allow for accurate billing and settlements within the NEM but will generally have a reduced set of technical specifications compared to Type 4 meters.
This change will enable new products, like street-side electric vehicle chargers or smart streetlights, to use the in-built meters, minimising the infrastructure footprint and lowering meter installation and maintenance costs. As with all meters, Type 8 and Type 9 meters will require pattern approval by the National Measurement Institute.
Settlement connection points
Under the current rules, each connection point to the NEM is limited to one Financially Responsible Market Participant
Connection points are metering installations with a physical connection to the distribution network
Large customers
Sometimes, it can benefit a large customer (defined by the AEMC as a customer that has a yearly energy consumption in excess of 100MWh1) to have more than one FRMP – for example, if they would like to buy energy from one Market Participant, but wish to use their generation assets to sell energy via a different Market Participant.
The new rule change will allow large customers to organise additional settlement points behind a connection point, allowing more flexibility in choosing how to operate and utilise large customer CER.
Large customers will have the option to use Type 9 meters at the connection point or additional settlement connection points instead of the standard Type 4 smart meter.
Small customer settlement points
The draft rules propose a similar arrangement for small customers while retaining vital consumer protections. Establishing additional settlement points could allow households and small businesses more flexibility with how they use their CER assets, like rooftop solar PV
It should be noted that the creation of an additional settlement point will not allow small customers to engage an additional FRMP. Instead, the existing FRMP (usually the retailer supplying the premises with energy) will be able to use the additional settlement point to optimise and coordinate flexible loads like CER.
Under the proposed rule, small customers will be able to use Type 8 and Type 9 meters at the settlement point, as an alternative to the standard Type 4 smart meter.

1 The qualifying load for a large customer varies by jurisdiction. Minimum yearly consumption requirements may be up to 160MWh, depending on the geographical location of the load.
