Connecting embedded generation


UPDATE
The model standing offer for micro embedded generator (inverter systems 200kw or less) has been updated and streamlined. These changes include some changes specifically relating to the requirements of the Distributed Energy Resources Register.

From 18th December 2021 all Inverters installed must be in accordance with AS/NZS 4777.2:2020 Grid connection of energy systems via inverters with the default regional setting selection set to “Australia A”.  For all other modes and operations that are not covered by a regional setting then default settings of AS/NZS 4777.2 2020 apply.

Prior to 18th December 2021, Inverters must comply with either:

  • AS/NZS 4777.2:2015 and Power Quality settings as described in Ausgrid Standard NS194 or
  • AS/NZS 4777.2:2020 with the default regional setting selection set to “Australia A”. For all other modes and operation that are not covered by a regional setting then default settings of AS/NZS 4777.2:2020 apply.

If you wish to install an inverter that complies with AS/NZS 4777.2:2015 it is strongly recommended you submit your application to Ausgrid by Friday 12 November to ensure you receive a connection offer by 18 December. Applications received after this date cannot be guaranteed to receive a connection offer by 18 December. In addition, if an application is submitted by 12 November but is incomplete or not correct we cannot guarantee we will be able to finalise our assessment by 18 December.

All inverters must be Clean Energy Council approved. A list of approved AS/NZS 4777.2 inverters can be found hereInverters compliant to AS/NZS 4777.2:2020 will be identified in the CEC list by the addition of the text “(AS4777-2 2020) after the device model number

An embedded generator is any equipment on your premises that can supply electricity. 

Embedded generation systems include

  • renewable systems (solar panels, wind turbines, hydro-generation)
  • battery storage systems that export electricity, including vehicle to grid (V2G) systems
  • combustion machines (diesel generator)
  • cogeneration and trigeneration.

For an infographic of how an embedded generator works visit AEMC here. You need to apply if you want to install embedded generation, even if you are installing a standby generator and don’t intend to export electricity back to the network. 

Are you connecting embedded generation within a multi-tenanted installation?

  1. Let us know whether you are part of a multi-tenanted premises. It is important prior to completing a connection application form that you have identified if your premises (NMI) is a part of a Multi-tenanted installation.

     - Multi-tenanted installations can be units, retirement villages, apartment blocks, shopping centres or any installation that has multiple premises (NMIs) connected to the network via a single point of connection.
  2.  

  3. During your application select 'YES' to the question: My premises (NMI)  is part of a multi-tenanted installation or embedded network that has an existing embedded generation already connected (NB: Multi-tenanted premises or embedded networks may include retirement villages, apartment blocks and shopping centres)”

  4. Your application should include total capacity of ALL existing and proposed Embedded generation for this Multi Tenanted Installation – (NB: this value must include ALL capacities for ALL  premises within the Multi- tenanted installation that have or are proposed to have embedded generation installed. You may need to approach your strata or site manager to obtain the total value).

  5. If you are a part of a Multi-tenanted installation your application may require technical assessment and added centralised protection requirements in accordance with AS4777.1.  Ausgrid recommends submission of a connection application form and approval prior to installing an embedded generation system. 

Installed generation equipment information must be provided to the AEMO DER Register

Once your application is approved you will be required to update information about installed generation equipment in the Australian Energy Market Operator’s (AEMO) Distributed Energy Resources (DER) Register.
  • Once your connection application for embedded generation has been approved by Ausgrid, as a condition of your customer connection contract, and in accordance with the Australian Energy Market Operator (AEMO) DER Register Information Guidelines, you will be required to provide details of any small generating unit at your premises.
  • This applies to all sizes of generator systems (including batteries and changes to existing systems), from small to large, that are not a registered participant with the AEMO.
  • The information needs to be provided within 20 business days of commissioning, altering or decommissioning generation equipment. 
  • Your installer or licensed electrician will provide information to the AEMO DER Register on your behalf. They will need to hold an account with AEMO for the DER Register and relevant details will be emailed to the connection applicant once an EG connection application is approved.
