Establish a connection using Embedded Generator (over 30kW)

Generators that are connected to the distribution network and do not have direct access to the transmission network are termed as Embedded Generators or Distributed Generators.

Embedded generators that are currently connected to the Energex network vary widely in type and size. Most are solar photo-voltaic (PV) generators connected to Energex and are typically less than 10 kilowatts in size. Others are co-generation plants, diesel units or large scale solar photo-voltaic (PV) generators that range from 30 kW to up to a few megawatts in size and better serve the needs of Energex's commercial and industrial customers. A very few embedded generator connections currently connected in Energex are larger than 5 megawatts and they sell the electricity generated directly to a single large consumer or into the National Electricity Market.

Energex supports customers wishing to connect embedded generators to the electricity distribution network across South East Queensland.

Process for connections 30kW up to 5000kW

These generators consist of cogeneration plants, landfill gas, solar photo-voltaic type ranging from 30 kW up to 5000 kW.

For these connections, an Enquiry must be submitted to Energex. Your electrical contractor can complete an Enquiry through the Electrical Partners Portal on your behalf.  Energex will conduct the necessary network investigations and provide an indicative estimate of potential costs and timeframes for you to make an informed decision. If your electrical contractor is unable to complete this form on your behalf, you can create the Enquiry through the Customer Portal.

Process for connections 5000 kW and above

With intention to reduce barriers to the connection of embedded generators(size greater than 5MW) to distribution networks, the Australian Energy Market Commission(AEMC) introduced a new connection process with well-defined timeframes including additional supporting information assisting the embedded generator proponents in making informed connection decisions.

New LV connection standard to be enacted 15 September 2017

Following the consultation of the draft Connection of Embedded Generating Systems (>30 kW to 1,500 kW) to a Distributor’s LV Network (released in May 2017), Ergon Energy Network and Energex are pleased to announce that this new joint standard for embedded generating systems connected to low voltage networks (>30kW up to 1,500 kW) will be enacted from Friday 15 September 2017.

We encourage you to review the new Connection of Embedded Generating Systems (>30 kW to 1,500 kW) to a Distributor’s LV Network   (PDF 999.6 kb) standard to ensure you are familiar with the changes to the technical requirements for connecting an embedded generating system >30 kW to 1,500 kW to our LV network.

Update on Joint Connection Standard for HV connected generating systems >30kW to 5MW

Additionally, 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 Standard for Connection of Embedded Generators (PDF 1.4 mb) remains current for embedded generating systems connected to the HV distribution network.
