We have several connection processes, depending on the size and regulatory classification of your proposed embedded generating system.
Generator registration with the Australian Energy Market Operator (AEMO)
Under the NER, any person who owns, controls or operates a generating system connected to a distribution network, must register as a generator with AEMO. The exception being where they either have the benefit of AEMO’s standing exemption (which usually applies to generating systems less than 5 MW in size) or have applied individually to AEMO and received a specific exemption.
Inverter-based generating systems up to 30 kVA are generally referred to as mini or micro embedded generating (micro EG) units. To connect a micro EG unit up to 30 kVA, please refer to the relevant sections on our Business connections webpage, or call 1300 553 924 (Mon to Fri, 8am - 5pm).
My EG System is >30 kW to 5 MW, has the benefit of the standing exemption and I do not plan to register with AEMO
These embedded generating systems can help manage your demand on our network during peak energy use times and assist in the event of emergency outages or supply interruptions.
Typically, such embedded generating systems benefit from AEMO’s standing exemption and are required to follow the connection process under Chapter 5A of the NER.
These EG systems include configuration arrangements > 30 kW to 5 MW, such as:
Non exporting embedded generator via an IES (including renewable energy sources such as solar)
Non exporting EG systems via rotating machines (i.e. diesel)
Exporting EG systems via renewable energy technology such as solar, wind and biogases
Anyone who intends to operate more than 30 MW of generation capacity and connect it to a distribution or transmission network in Queensland, must first hold a generation authority or special approval. This authority is issued by the Department of Energy and Water Supply (DEWS).
A failure to hold such an authorisation is an offence under the Electricity Act 1994 (Qld).
If you are proposing to operate more than 30 MW of generation capacity at a site and connect it to a network, we strongly suggest that you contact DEWS early in your planning process. This will allow for the application to be made to the Director General, considered and approved before the proposed connection. The process can typically take four months from application.
You can contact DEWS via email to discuss licensing requirements and the application process.
To establish or modify a generation connection to our distribution system, we require you to enter into a Negotiated Connection Establishment Contract (PDF 999.0 kb) (we refer to this as the Construction Contract). This sets out the works that both parties will need to perform for the connection.
*The joint Ergon Energy and Energex connection standard for HV connected generating systems >30 kW to 5 MW is being drafted and will be released for comment in coming months. Until the joint standard is released, the STNW1165 - Standard for Connection of Embedded Generators remains current for embedded generating systems connected to the HV distribution network.
