Powerline upgrades in Port Noarlunga to Seaford
What we are doing
We're replacing 28kms of high voltage powerlines in Mclaren Flat, Willunga, Port Noarlunga, Aldinga and Seaford to maintain power reliability and ensure we can meet increasing local electricity demand.
How this affects you
Our contractor Equipped Civil will excavate and install pole footings along Commercial Road from January 2026.
They will be using ‘vacuum excavation’ methods which is less disruptive to underground services, however is very noisy. We apologise in advance to those who live nearby and may experience some disruption.
Our powerline crews will replace 27 Stobie poles along Commercial Road from Monday 9 February 2026. The new poles will be replaced in the same or a similar location to the existing poles.
There will be no power outages during this part of our work.
Our powerline crews will return between July and September 2026 to replace our overhead powerlines.
All works will be completed between Monday and Friday between 8am and 3pm, with the possibility of some weekend works.
Traffic management
Traffic management will be in place while our crews are working. Temporary speed limits, lane closures, partial road closures, and possible detours will be in place for the safety of workers, road users and pedestrians. We will minimise disruption as much as possible and appreciate the continued patience and support of our local community and visitors affected by this work.
Power outages
We will notify customers in advance of any power outages that may affect them in late 2026.
We encourage anyone not already subscribed to sign up for updates using the National Meter Identifier (NMI) found on your electricity bill.
Subscribing is a helpful way to receive updates related to planned and unplanned power outages, as well as other disruptions such as night works or noise.
