Embedded generation

This page explains how to arrange for connection of an embedded generator (such as a solar system) to the SA Power Networks distribution network. The term 'embedded' applies to both small and large-scale generators.

Small embedded generators

Small Embedded Generators are defined for the purpose of the Guide as embedded generator installations complying with the relevant Australian Standard AS4777 (grid connection of energy systems via inverters), parts 1, 2 & 3. For installations complying with AS4777 with grid connected inverters, we will connect single phase installations up to a maximum of 10 kVA and three phase installations up to a maximum of 30 kVA.

The applicable standards for small generators are contained within our Small Embedded Generation Technical Guidelines

If you have any questions or wish to investigate the potential connection of a small embedded generator to our Network, please contact:

Large embedded generators

Large Embedded Generators are defined as having a generating capacity greater than 10kVA for a single phase connection, and greater than 30kVA for a three phase connection. Large Embedded Generator installations, whether export or non-export, connected to operate in parallel with the SA Power Networks network, must be assessed by us for suitability for connection and compliance in all respects with SA Power Networks' technical standards. 

Guidelines and Technical Standards

Register of Completed Projects

Each year, SA Power Networks produces a Register of Completed Embedded Generation Projects in accordance with the requirements of Section 5.4.5 of the National Electricity Rules (NER). 

The register contains a list of completed embedded generation projects that meet the following criteria:

  • Embedded Generating Units owned, operated and controlled by a Generator or by a person who was required to apply to AEMO for an exemption from the requirement to register as a Generator; and
  • Generating Systems comprising of embedded Generating Units with total nameplate capacity greater than 5MW; and 
  • Generating Systems connected to SA Power Networks' distribution network with the 5 year period preceding the date of publication of the register.

The register includes, but is not limited to, the following information:

  • Technology of the Generating Unit(s), including make and model;
  • Maximum power generation capacity of all embedded Generating Units;
  • Contribution to fault levels;
  • Size and rating of relevant transformers;
  • Single line diagrams of the connection arrangement;
  • Protection systems and communications systems;
  • Voltage control and reactive power capability; and
  • Details relevant to the specific location of the facility.

Please note that this register does not publish any confidential information as part of, or in connection with, the register. 

SA Power Networks will update this register each year by 1 November.
