A pair of new technical standards will require that prescribed generating systems connecting to the South Australian distribution network are capable of being dynamically export limited and for export limits to be updated remotely.


The Minister for Energy and Mining has by notice in the government gazette, set the prescribed date for dynamic export requirements to 1 July 2023. Amendments to the below guidelines have been published to reflect the prescribed date and regarding changes to requirements for zero-export sites, batteries, medium embedded generators and on-site commissioning.

The document below also contains several existing guidelines relating to distributed energy resources.

The two new guidelines are preceded by an explanatory section titled Introduction to Dynamic Export Requirements, which provides a brief overview of the scope, use-cases, site compliance and responsible parties involved in enabling dynamic exports. The Remote Updating Methods guideline, provides requirements that relate to communications between a distribution network operator and a site. The Export Limiting Methods guideline should be read with this, and provides requirements for electricity export limitation on site.

In most cases, new generators connected to the electricity distribution network in South Australia are required to be configured to export energy to the grid up to a static limit. The requirement for a static export limit ensures that the power system can operate correctly even if every generator is exporting energy.

For much of the year, the power system is able to support exports above the static limit and, with the continued growth of rooftop solar generation it is likely that the static limit will need to be reduced to ensure safe operation of the power system at all times.

A standard which came into effect as of 28 September 2020 requires that the owner or operator of an electricity generating plant that will be installed on the South Australia distribution network ensure that the inverter is remote communications capable.

Details of the communication capabilities required of inverters are provided in the Technical Regulator Guidelines - Distributed Energy Resources (PDF, 2.7 MB)

To enable the continued installation of distributed generation, and to deliver maximum value to owners of these generators, from 1 July 2023, as prescribed by the Minister for Energy and Mining, prescribed electricity generating plants must be capable of remotely updating and enacting dynamic export limits, unless a relevant exemption applies.

This will contribute to the ability of the distribution network to host new distributed energy resources. Dynamic export limits can avoid scenarios where the energy exported under existing static export limits may exceed the capacity of the local network, or where there is insufficient demand for that energy in other parts of South Australia.

These new guidelines will establish the groundwork for connections which can support dynamic exports in South Australia and should ensure that once the new requirements are in place – most sites installing distributed generation such as rooftop solar are requested to be dynamic export capable. Owners of these systems will then be able to take advantage of connection agreements which allow for dynamic export limitation once these become available.

From the date prescribed by the Minister for Energy and Mining, where components of a designated electricity generating plant are replaced, this also requires that plant meet the dynamic exports requirements.
