Decommissioning of Dalley Street Zone Substation

Located in the northern part of Sydney CBD, Dalley Street Zone Substation currently supplies 4,924 customers with a mix of residential and commercial properties. The project will transfer 39MVA load from this zone substation to Belmore Park Zone Substation.

Following notifications issued earlier in the year, the associated investigation works are now complete. These investigations have allowed us to finalise our design and engage a contractor to complete the installation of the conduits and 11,000V cables required for the project.

Ultegra will be doing the work on behalf of Ausgrid. Work is expected to start in early January 2022, when traffic volumes are lower to reduce the total length of the project and the amount of night work required after the holiday period. We will provide further information and notify you a week before we start the work.

The work will involve excavating a trench about a metre wide in the roadway in Bent, Hunter Bridge and Macquarie Streets and laying conduits (plastic pipes) to house the new cables.

The cables will then be installed in mid-2022.

Working hours

Bridge Street work

In April 2022, we letterbox dropped and emailed all impacted buildings to discuss the proposed works. We would like to thank everyone who responded with feedback. We have been carefully considering all the feedback provided to date and have been negotiating and making arrangements to incorporate into our works program.

The project has received majority support to increase our work up to five nights a week to minimise the construction program and complete the works as quickly as possible.

We have also received some concerns about night work and the length of the work and have taken on board this feedback. To address your concerns, we have talked to Traffic Management Centre (TMC) to seek approval to do more of our work during the day and complete the majority of the work in May. These changes will provide three nights of respite during the week.

We have received approval from the TMC for limited day works (Saturdays and Sundays) when the traffic volumes are lower and have a further requests pending.

In Bridge Street, we are now planning to work:

• Saturday and Sunday from 6am to 10pm with noisy work after 7am
• Monday to Thursday nights from 9pm to 5am - we have put forward a case with the TMC to allow access to Bridge Street earlier in the evening
• Monday to Friday from 10am to 3pm (as required) to do noisy saw cutting. This request is pending with the TMC and would remove the requirement to complete these works at night.

We apologise for any inconvenience this may cause you.

Macquarie, Bent and Hunter Streets

In April 2022, we letterbox dropped and emailed all impacted buildings to discuss the proposed works. We would like to thank everyone who responded with feedback. We have been carefully considering all the feedback provided to date and have been negotiating and making arrangements to incorporate into our works program.

We will come back to the community shortly with an outcome to this consultation.

Working hours will continue to be 7pm to 5am, doing the noisiest activities (saw cutting and rock breaking) before midnight, where possible. We will continue to seek road licensing approvals for day and weekend work to reduce the impact of night work on residents.

Keeping you informed

Ausgrid will issue email notification updates detailing work locations and dates. Residents can register for these updates to be emailed to them at majorprojects@ausgrid.com.au.

For information related to the project, you may contact Ausgrid on 1800 604 765 or at majorprojects@ausgrid.com.au.

We thank you for your continued patience as we work to improve the network reliability in the area.

Under the Environmental Planning and Assessment Act 1979, Ausgrid is the determining authority for the various stages of this project. Environmental assessments are prepared for each stage in accordance with Part 5 of the Environmental Planning and Assessment Act 1979 and Clause 228 of the Environmental Planning and Assessment Regulation 2000.

Like on many construction sites there will be typical construction impacts such as noise and dust. Ausgrid assesses potential impacts as part of the environmental assessments and puts measures in place to minimise impacts on the local environment.

Impacts to residents and businesses will vary during each stage of the project and will depend on proximity to assets. Initially impacts will include parking/traffic restrictions, but there will also be construction related impacts during some stages. The project will generate noise and dust, which we would work to reduce as much as possible.

Ausgrid will continue to provide regular updates to the community living or working in the areas where we are, or plan to be working.
