Do nothing 2. Maintain and repair 3. Replace License requirements: To maintain a safe and reliable supply of electricity to our customers 9 How we plan projects Sustainable decisions must balance all of these factors 10 Planning so far • Initial investigations • Pinch point areas highlighted • Site visits and investigations • Potential route options • Desktop analysis • Council meetings • Refine to feasible route options 11 Where we are at now 12 Any questions? • Questions? • Comments? • Feedback? 13 What to expect during construction Project Manager Mayur Kulkarni Typical underground cable project - excavation 15 Typical underground cable project – cable trench 16 Modern typical cable installation – 33,000 Volt cables backfill backfill 17 Conduit installation 18 Semi-permanent restoration following conduit install 19 Joint bay installation 20 Conduits entering joint bay and communications pit 21 Cable pulling 22 Cable joining 23 Testing 24 Underground 33,000 volt cable installation 25 Similar recent/current cable projects • Surry Hills to Rose Bay cable project • Engadine cable project • Sydney Olympic Park cable project • Beaconsfield to Kogarah cable project • Homebush to Rozelle cable project • North Shore cable upgrade project • Carlingford cable project • Pyrmont to Camperdown cable project • Pymble to Lindfield project 26 Summary • Modern cable installation is less disruptive, but there are still impacts we need to manage. • Factors to consider when planning to install cables are many and sometimes competing. • Experience of previous projects informs planning. • Local knowledge is a key part of the process. 27 Any questions? • Questions? • Comments? • Feedback? 28 Next steps: • How your feedback will be used in the project planning process. – Feedback forms – Consolidation and incorporation into plans – Decision – Environmental assessment 29 Key dates: 30 Community Newsletter – June 2016 Earlwood to Summer Hill cable project A similar cable project in progress Consulting on new cables What we have done so far Ausgrid is planning to replace underground electricity Initially our planning focussed on potential ways to cross cables that run between our substations at Earlwood and the Cooks River and the Bankstown Line railway as this would Summer Hill. The existing 33,000 volt cables are nearing the have a significant influence on the potential cable routes. end of their service life and need to be replaced so Ausgrid can maintain a safe and reliable power supply to the area. Potential options for these crossings included boring underneath the river or attaching the cables to existing The new cables would be connected to a new substation bridge structures. A range of initial route options was in Summer Hill which is required to replace the existing developed for further investigation and Ausgrid began facility (known as the Dulwich Hill zone substation) before consultation with the then Canterbury Council (now it becomes unreliable. The new substation is proposed to be Canterbury-Bankstown Council). built on land next door and Ausgrid has been consulting with surrounding residents on these plans. Ausgrid investigated these routes with consideration of the factors listed earlier in this newsletter and after further We are working to plan a cable route between Earlwood and consultation with Council. Summer Hill and would like your feedback on the potential options. Community feedback will be considered by Ausgrid Following this process, Ausgrid refined the potential routes as we make a decision on a proposed cable route and develop to a number of feasible options and we are now seeking the construction plans. community feedback. You have received this newsletter because you live or work near one of the cable route options we are considering. There is a map showing the potential cable route options on the inside pages of this newsletter. Have your say Things we consider Community feedback will help Ausgrid choose from As we plan this cable project, there are a range of factors a number of potential cable routes and plan the Ausgrid needs to consider, including: project to minimise impacts during construction. • cost (minimising the impact on electricity bills) See the back page of this newsletter for details on • community impacts the upcoming community information sessions. • availability of space around existing utility services • environmental and heritage impacts • technical feasibility • traffic impacts • crossing Cooks River and the Bankstown Line railway.

We invite you to attend the sessions to find out more about the project, provide feedback on potential route options and speak with the project team. No appointment is necessary, just drop in. At the beginning of each session, members of the project team will give a short presentation. Community session 1 Date: Tuesday 21 June 2016 Venue: Canterbury Hurlstone Park RSL Club RTO Room Address: 20-26 Canterbury Road, Hurlstone Park Time: 6pm to 8pm (presentation from 6.15pm) Community session 2 Date: Thursday 23 June 2016 Venue: Ashfield Civic Centre Patricia Blackman Room (Room 2) A similar cable project in progress Address: 260 Liverpool Road, Ashfield Next steps Time: 4.30pm to 6.30pm (presentation from 4.45pm) The table above provides an overview of the project stages. After considering and addressing feedback from the community and further planning, Ausgrid will select a preferred cable route for environmental assessment. There will be further newsletters with updates, including information about how we have used the community’s Contacting us feedback. There will also be an opportunity to make a submission on the environmental assessment for this project.
