| Cannonvale-Shute Harbour (PDF, 1.4 MB) | Non-Network Options Report | Cannonvale 66/11kV substation (CANN) and the surrounding 66 kV sub-transmission network supplies approximately 7,198 customers including major customers such as the Proserpine Sugar Mill, Hamilton Island, South Molle Island and Daydream Island.
The 66 kV sub-transmission network in the Cannonvale and Jubilee Pocket area consists of radial 66 kV timber pole lines with a number of sections of underground cable. There is currently no remote switching capability.
In its current state, due to the radial nature of the network and the reliance upon manual switching, a credible fault on the sub-transmission network in the Cannonvale and Jubilee Pocket area would mean that load cannot be restored within the requirements of the Safety Net security criteria, with this situation worsening as load increases.
This report is an invitation to registered participants and interested parties to make submissions on credible options to address this identified need. | 24 Jun 2019 | 19 Sep 2019 |

| East Bundaberg (PDF, 329.4 KB) | | Bundaberg is a regional city located 360km north of Brisbane with a population of approximately 93,000 people. East Bundaberg 66/11kV Zone Substation (EABU) is located on the eastern edge of Bundaberg city and supplies a diverse mix of industrial, residential, and agricultural zones. There are approximately 8900 customers connected to the distribution network, including a number of major commercial and industrial customers located in Bundaberg and further north at Burnett Heads.
A condition assessment of East Bundaberg Zone Substation (EABU) has identified assets that are recommended for replacement. These assets are forecast to reach retirement based on a combination of Condition Based Risk Management (CBRM) modelling and known issues with problematic plant, which are required to be replaced or decommissioned to manage the safety and network risks associated with unplanned failure.
The internal investigations undertaken on the feasibility of the non-network solutions revealed that it is unlikely to find a complete non-network solution or a hybrid (combined network and non-network) solution to provide the magnitude of network support required in the East Bundaberg area to address the identified need.
The preferred network option is to replace the assets in poor condition. This notice of no non-network options is therefore published in accordance with rule 5.17.4(d) of the National Electricity Rules. As the next step in the RIT-D process, Ergon Energy will now proceed to publish a Final Project Assessment Report. | 23 Jun 2020 | |

| Pittsworth (PDF, 1.2 MB) | Non-Network Options Report | Broxburn substation 33/11kV supplies the township of Pittsworth. Maximum demand in 2018 exceeded the substation nameplate capacity and is expected to exceed the emergency cyclic capacity by 2022. The two transformers at Broxburn substation were manufactured in the 1960s that they are near end of life including associated high voltage switches. Ergon Energy has proposed to address these limitations by installing a 10MVA skid transformer and completed by December 2021. This report is an invitation to registered participants and interested parties to make submissions about possible alternate solutions to address the identified limitations. | 01 Jul 2019 | 10 Jan 2020 |

| Wide Bay Burnett (PDF, 1.1 MB) | Non-Network Options Report | The existing 66kV M028 feeder forms part of the 66kV subtransmission network supplying the 66/11kV zone substations Degilbo, Gayndah, Mundubbera Town and Eidsvold as well as the Mount Rawdon gold mine. Feeder M028 is 92km long, 64 years old and has reached its end of life based on the condition of the 7/.104 HDBC conductor and wooden poles. Ergon Energy has identified that the preferred internal network option is to replace the entire aged M028 feeder with a new 66kV single circuit concrete pole feeder, strung with Neon conductor and optical ground wire (OPGW), originating from the 132/66kV Isis Bulk Supply Point and connecting Degilbo and Gayndah zone substations by December 2023.
This is a Non-Network Options Report, where Ergon Energy is seeking information from interested parties about possible alternate solutions to address the need for investment. | 16 Oct 2019 | 16 Jan 2020 |
