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 our network vary widely in type and size. Most are solar photo-voltaic (PV) generators 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 our commercial and industrial customers.

A very few embedded generator connections currently on our network are larger than 5 megawatts and they sell the electricity generated directly to a single large consumer or into the National Electricity Market.

We support customers wishing to connect embedded generators to the electricity distribution network across South East Queensland.

Draft Connection Standard for HV connected generating systems open for comment

We are seeking feedback on our draft Standard for Connection of Embedded Generating Systems to the HV Distribution Network (PDF). This joint standard with Ergon Energy Network will apply to all embedded generating systems connected at either low voltage (LV) or high voltage (HV), where the connection point with us is to the HV distribution network.

We are reviewing the feedback received on the draft via our Talking Energy website. The new HV Embedded Generation Standard is expected to be released shortly.

Until the joint standard is released, these three documents remain current for embedded generating systems connected to the HV distribution network:

• Standard for Parallel Embedded Generation via Inverters 30kW-5000kW - STD00233 (PDF 739.3 kb) for systems less than 5 MW
• Standard for Embedded Generators 30kW-5000kW - STD00657 (PDF 787.7 kb) for rotating machines less than 5 MW
• Standard for Large Scale Embedded Generation 5MW and above - STD01188 (PDF 583.6 kb) for systems 5 MW and over.

Process for connections 30 kW up to 5000 kW

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 us. Your electrical contractor can complete an Enquiry through the Electrical Partners Portal on your behalf.  We will conduct the necessary network investigations and provide an 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.
