Connection process

A Micro Embedded Generator is a sub-classification of Embedded Generator. Most residential solar and battery applications fall into the Micro Embedded Generator category. Any application which does not meet the Micro Embedded Generation criteria will be assessed under the Negotiated Embedded Generation process.

To help clarify these definitions, we have provided a comparison below. Please note that we don’t provide standard connection services (as defined in the NER) for any generation connection.

Basic Micro Embedded Generation

Generator type: AS4777.2 compliant inverters are required for inverter-based generation. Inverter settings must be as per AS4777.2.2.2020: Australia A (for more information, refer to our Smart Inverter Settings page)

Total capacity on premises (kVa): Total installed capacity less than or equal to 30kVA

Export limit (kw): The maximum export limit for specific phasing on our network is as follows:

• Single and two phase maximum export of 5kW (for all connections including SWER).
• Three phase maximum export of 15kW

How to apply: visit the Rooftop Solar page

Application process:

1. Submit a Solar Pre-Approval application via the online connection application service. This is necessary to approve the customer’s intended system size and assess the export available to the customer.
2. Once submitted, you will receive an email notification with the attached pre-approval outcome within minutes. Our response will include the approved solar export limit, along with additional information to help you understand the technical requirements for installing your solar system. Note: The most basic connections are covered under the model standing offer (MSO). For connections up to 30kVA outside of the MSO will be covered under a Generator Agreement.
3. When the installation and inspection has been completed, you will be required to submit an Alteration request along with the Certificate of Electrical Safety via the online connection application service.
4. We will then notify your energy retailer that we have reconfigured the meter and update the Distributed Energy Resources Register (DERR) accordingly.

Negotiated Embedded Generation

Generator type: AS4777.2 compliant inverters are required for inverter-based generation connecting to the grid at LV. All other generator types are subject to negotiation with UE.

Total capacity on premises (kVa): Dependent of network constraints at point of connection

Export limit (kw): Dependent of network constraints at point of connection

How to apply: Visit our Negotiated EG Connections webpage

Application process:

1. Submit an application for Preliminary Assessment of the network capacity via the online connection application service.
2. Receive a response from United Energy. Our response will include copy of the outcome, along with information to help you understand the costs, benefits, and technical requirements for installing your solar/battery system.
3. Apply for Embedded Generation Connection (go to our Negotiated EG Connections webpage to obtain the relevant form). For more details about the negotiated application process, refer to the EG Customer Connection Procedure - UE-PR-2008.
4. Once a sanction to connect has been issued by UE, the REC or accredited installer shall submit an alteration request and Certificate of Electrical Safety also via the online connection application service
