30kW – 1.5MW connections

  

This page is for you if you are an Installer, Solar Retailer or Registered Electrical Contractor (REC) and you are designing a system that is over 30kW and up to 1.5 MW. Installations of this size require a detailed technical assessment.

These are typically commercial or industrial systems that may require changes to the network to accommodate them. All of these systems will require Central Protection (refer to SOP 11-16).

The total administration fee for these projects is $2000.00 (excl. GST) for systems up to 200kW and $3000.00 (excl. GST) for systems greater than 200kW and up to 1.5MW. There may be additional fees if changes to the grid are required e.g. upgrading a transformer.

With large installations like this you will be responsible for undertaking specialised commissioning tests (SOP 33-07 & SOP 33-08) to demonstrate compliance with our requirements. 

If you have any questions about this process, or would like to track the progress of your application, please contact preapprovals@ausnetservices.com.au.

  • 1. Design system and apply for approval to install

    We are responsible for providing a safe and stable energy network (grid) for our customers and workers. This is why all new renewable energy installations must be approved by us.


    Our process

    You will need pre-approval from us before you can start installing the system for the customer.

    All systems greater than 30kW are manually reviewed by one of our technical assessors. They are responsible for evaluating the effects of your proposed design on the network and checking that there is enough capacity to host your system.

    The steps to apply are:

    1. Submit our pre-approval form with the details of the system you intend to install (including your For Construction Single Line Diagram).
    2. Once we receive your completed application, we will send you an invoice.
    3. Once the invoice is paid our technical assessors will evaluate your application for pre-approval.

     

     

    Our requirements

    Your proposed installation must comply with the requirements in the following documents:

    • Protection Requirements of Embedded Generators (LV + HV up to 22kV) - SOP 11-16
    • Central Protection Commissioning Test Report - SOP 33-07
    • Power Quality Compliance Requirements - SOP 33-08
    • Single Line Diagram Requirements. SLD must be in electronic format, incorporate central protection relay and describe the proposed installation.

    To apply, send us:
    • Completed Embedded Generator and Battery Storage Pre-Approval Form
    • Single Line Diagram (SLD), that incorporates central protection relay and describes the proposed installation. Must be in electronic format.
    • Invoice payment (this must be paid before technical assessment can commence)

     

    Costs

    $2000.00 (excl. GST) for systems up to 200kW

    $3000.00 (excl. GST) for systems greater than 200kW and up to 1.5MW.

     

    Time frame

    Up to 65 business days

  • 2. Install system and perform commissioning tests

    Our process

    If your application is successful we will email you an approval letter outlining the conditions for approval, along with a formal Connection Agreement.

    Alternatively we will contact you with options for getting your system approved. For example, reduce the system size, limit the power exported from the installation or strengthen the network (such as a bigger transformer or extra poles and wires).

    You may install the system after you have received an approval letter from us. In order to undertake the commissioning tests, we will allow the temporary connection of the system in accordance with Central Protection Commissioning Test Report (SOP 33-07) and Power Quality Compliance Requirements (SOP 33-08).

     

     

    Our requirements

    The installation of the system is subject to all of the following:

    • We must be notified a minimum of 10 business days prior to the commission test date to enable us to witness the commission testing if we outline this requirement in our approval letter
    • Until the final Connection agreement is executed, the inverter must not be connected to AusNet Services distribution system and the lockable switch must remain locked in the open position. The exception to this requirement is that the inverter may be connected to AusNet Services distribution system for the purpose of commissioning tests.

    If you need to change the system you’ve been given approval for, you may need to reapply. Please discuss your intended changes with our Technical Assessor.

     

    Costs

    If we need to strengthen the network to approve of the system (such as a bigger transformer or extra poles and wires), we will let you know the costs for this.

     

    Time frame

    The system must be installed within 90 business days of approval

  • 3. Submit paperwork for approval to connect to the grid

    Our process

    Once you have installed your system, we need to review the commissioning tests results to ensure that it is working safely and as it should.

    Please email the information below to preapprovals@ausnetservices.com.au for us to review for final approval to connect:

    1. Connection Agreement signed by the customer
    2. Completed Electrical Works Request (EWR)
    3. Completed Certificate of Electrical Safety (CES)
    4. Commissioning Test Results

     

     

    Our requirements

    The final connection of the system is subject to all of the following:

    • Execution of the Connection Agreement
    • The electrical installation must have passed the prescribed inspection and have a valid Certificate of Electrical Safety (CES)
    • Satisfactory commissioning of the system for compliance with AS4777 and with AusNet Services’ “Central Protection Commissioning Test Report” (SOP 33-07), and a copy of the commissioning test report, including the CES, must be provided to us.

     

     

    Costs

    There are no costs for this part of the process.

    If you do not proceed to install you are eligible for part-refund of your initial fee. Get in touch with us to discuss.

     

    Time frame

    10 business days - Approximate time we need to review completed test results and provide final approval.

  • 4. Meter reconfigured – ready to switch on

    Our process

    The final step in the process is having your meter updated to record energy generated on site.

    In order for this to happen, you must send the following documents to your customers retailer:

    1.  Connection Agreement signed by the customer and counter-signed by AusNet.
    2. Completed Electrical Works Request (EWR)
    3. Completed Certificate of Electrical Safety (CES)

    Your customer's Metering Provider (this may or may not be us) will receive the documents from your customers’ retailer. Once the paperwork has been reviewed the meter will be reconfigured to record energy generation. Please note, the electricity tariff will potentially change.

    Your customer may now switch on the system and begin generating their own energy.

     

     

    Our requirements

    Your customer's energy retailer must request these metering changes from us (or their Metering Provider) before we can proceed.

    There can only be one meter at each location. If there are more we will need to consolidate them - this requires a technician to visit the premises (truck visit).

    If the premises does not have a smart meter, a manual reconfiguration will need to take place with a truck visit.

     

     

    Costs

    If we are the Metering provider: Your customer will be billed via their retailer:

    $28.65 - Electronic Meter reconfiguration

    $335.00 - Truck visit (if applicable)

     

    Time frame

    If we are the Metering provider:  10 business days - For us to approve the final installation and reconfigure the meter, after we receive it from the retailer.
