Renewable generation project connection

Your renewable generation project 

You can inquire about a renewable generation project through our online mySupply service.  

Please note, there are different forms for embedded generation and battery storage projects.

Connection application 

We review connection applications against the network automatic access standards.  

We notify AEMO when standards are agreed for registered generators with a capacity greater than 5MW.  

An AEMO approved power system model (PSCAD) may be required. This applies if the preliminary system strength impact assessment shows a full assessment is needed. AEMO is responsible for reviewing the full assessment.  

We prepare the formal connection offer when the assessment is accepted. It includes an itemised statement of costs, payment schedule and a construction schedule. By this point, a formal offer from the transmission network (AEMO or AusNet) is provided.  

This forms a contract between Powercor or CitiPower and the applicant. It includes: 

•  An Augmentation Agreement with timeframes, costs and commercial arrangements for the connection works.  
•  A Generator Deed with conditions to permit the generator to connect to the network. 

Technical requirements 

Technical guidelines are available depending on the voltage level of the connection. At a minimum, they provide the following information:  

•  Single line diagrams of the DNSP preferred connection arrangements  
•  Sample schematic diagrams of protection systems relevant to the connection 
•  Protection systems and protection schemes
•  Fault level management principles
•  Reactive power capability and power factor correction
•  Power quality
•  Frequency and voltage disturbance
•  Voltage control and regulation
•  Remote monitoring equipment, control and communication requirements
•  Earthing requirements and other safety requirements
•  Commissioning and testing requirements 

Typical connection costs

Indicative costs of typical connection assets for embedded generation are below. Costs may vary according to: 

•  the size of the embedded generator 
•  its location in relation to existing distribution assets 
•  the voltage level of the connection. 

Note:  these do not include costs to remove a network constraint.
