MacIntyre Designated Network Asset

Australian Energy Regulator Approval Date

The Access Policy for the MacIntyre Designated Network Asset (DNA) was approved by the Australian Energy Regulator (AER) on 4 April 2024.

For the purpose of Appendix F of the Access Policy, the end date of Foundation Proponent No.1’s connection agreement is 9 February 2054.

Details of MacIntyre Designated Network Asset Capacity and Facilities of Existing Connected Parties and Conditional Proponents (as at the AER Approval Date) 

Schematic of the connection configuration for the MacIntyre DNA and associated assets (as at AER Approval Date)

Note: The Tummaville Switching Station (the IUSA) is divided into IUSA Shared Facilities and IUSA Non-Shared Facilities. Based on the current configuration shown in the schematic above, the IUSA Shared Facilities are considered to be six ninths of the IUSA. The blue shaded areas represent the three bays used to provide negotiated transmission services to the MacIntyre DNA (the IUSA Non-Shared Facilities).

Main components of the connection

Refer to the hybrid general arrangement drawings for MacIntyre Intermediate Switching Station and Tummaville Switching Station for further details. 

MacIntyre DNA capacity

The MacIntyre DNA is primarily limited by the thermal capacity of DNA Component 1 (the 330kV transmission lines between Tummaville Switching Station and MacIntyre Intermediate Switching Station). DNA Component 1 includes two circuits, and under normal operating conditions, each circuit has a limiting thermal capacity of 913 MVA based on the summer normal rating (refer to Table 1 in the MacIntyre DNA Access Operational Protocol for further details). Note the DNA Capacity is subject to non-DNA limitations/constraints/conditions existing, from time to time, on the Shared Transmission Network that impact the maximum capacity into, across and out of the MacIntyre DNA.  

Powerlink will engage with an Applicant in more detail about its desired Agreed DNA Transfer Limit for DNA Service 1 for a proposed connection project prior to and/or after a DNA Access Request has been submitted.

_{*The Agreed DNA Transfer Limit for Karara Wind Farm and Herries Range Wind Precinct will be subject to change depending on the Performance Standards that are approved pursuant to the Rules.} 

A congestion management scheme will be introduced to manage access to the thermal capacity of the line during MacIntyre DNA congestion, but the scheme will not apply to the Foundation Proponents.

MacIntyre DNA Capacity limitations

The DNA Owner, in its capacity as DNA Owner, has no responsibility and can give no guarantees about power transfer capability from the Boundary Point, as these matters are subject to Network Limitations and are beyond the control of the DNA Owner.

Conditional Proponent Terms

The DNA Owner may offer an Applicant an Access Agreement to become a Conditional Proponent, in return for a fee. View the Conditional Proponent Terms and Conditions. Back to Designated Network Assets
