Pending approval, this project would involve installing the new 132,000-volt cable and spare conduit through streets in Matraville and Maroubra. Retiring the existing cable between the substations would involve some work at various locations along that cable route and at the substations themselves.
As with any construction work, there would be some noise and dust, and temporary traffic, access and parking disruptions, but we would make every effort to keep these to a minimum.

Work to install the new cables would generally include:
- digging trenches in roads to lay conduits (plastic pipes) to accommodate the new cables
- backfilling trenches and temporary resurfacing of impacted areas (trenching and temporary resurfacing takes about three days outside each property depending on ground and weather conditions)
- excavating underground joint bays at various locations along the cable route
- feeding in and joining sections of cable at the joint bay locations
- permanently restoring impacted areas, in consultation with Council once the overall project is complete
Work to retire the existing 132,000 volt cables would involve:
- excavating existing joint bays along the cable route
- removing fluid
- removing cable equipment
- disconnecting the cables
- backfilling excavations
