1. InstructionsIn accordance with clause 5.3.4 of the National Electricity Rules (NER), this application form gathers the information ElectraNet requires to progress an application to connect to the South Australian transmission network and the National Electricity Market (NEM).

Before you complete this form, we recommend you take the time to understand the connection process and have early conversations with our Business Development team, to receive appropriate advice for your situation. The team is here to help and would welcome a chance to discuss how we can help deliver your project.

ProcessThere are three key stages to the transmission network connection negotiation process: the initial connection enquiry; this application to connect stage and the final offer to connect stage, which will involve the negotiation and execution of a transmission connection agreement between you and ElectraNet.

Before completing this form, you must have submitted a connection enquiry, in accordance with clause 5.3.2 of the NER, and have received our response in accordance with clause 5.3.3 of the NER.

Before ElectraNet will process the application to connect, you must have executed a Preliminary Works Agreement for ElectraNet to support your application. ElectraNet would be pleased to provide you with a proposal for these services when required.

ElectraNet requires that the information outlined in its Generator Connection Checklist, including your proposed technical access standards, be submitted as part of this application to connect form.

In addition to the information to be provided with your application to connect, if any services related to contestable IUSA components are not to be provided

by ElectraNet, the Connection Applicant must also provide the information outlined in section 4 of this form, in accordance with clause 5.3.4 of the NER. Please note if ElectraNet is to provide services related to contestable IUSA components, the information outlined in section 4 need not be submitted with your application to connect.

After reviewing your completed application to connect form, we may ask you for additional information better understand your requirements and process your request.

NotesThe application to connect form has two parts: connection requirements relating to entry points (generation facilities) and connection requirements relating to exit points (direct connect (load) facilities). Please only complete the section that relates to your type of connection application.

Definitions and terms used in this form are explained in section three and can also be found in chapter 10 of the NER. Italicised terms used in this form defined by the NER.

3. Required Information Guide3.1 Entry points

Source of supplySingle line diagram Note: This should be submitted with this application to connect form

Applicant to provide a single line diagram that outlines the nature of the required connection – single switched, double switched, one and a half CBs, ROIs etc.

Maximum continuous current rating (Amps)

This will be used to determine the rating of the primary and secondary plant. If any form of short term overloads is anticipated, theses should be mentioned in this section.

Type of loadSpecify the general nature of the connected load (e.g. large motor drives, controlled rectifiers, battery etc) and identify any particular impacts on the Connection Assets and whether demand is to be firm.

Circuit breaker and extra high voltage (EHV) plant control

Auto-control schemesSpecify any requirements for auto-control schemes such as auto-closing or opening of CBs (other than auto-reclosing), giving an overview of the required functionality.

Synchronising and synchronism check Specify whether it is needed for manual, auto or for both.

Protection systems

X protection

Specify protection type (i.e. distance, current differential, pilot-wire, directional over current etc.) and preferred vendor device if applicable.

Typically the generator and the generator transformer protection are owned by the connection applicant and the X and Y protection operates directly into ElectraNet’s EHV Assets via an approved dedicated interface. Note that any deviation from the standard ElectraNet applied protection relays may attract additional costs.

Y protection


Typically the generator and the generator transformer protection are owned by the connection applicant and the X and Y protection operates directly into ElectraNet’s EHV Assets via an approved dedicated interface. Note that any deviation from the standard ElectraNet applied protection relays may attract additional costs.
