Undergrounding powerlines in Jamestown

Notification of works

September 2023 - April 2024

What we are doing

SA Power Networks is working in partnership with Northern Areas Council to underground powerlines along Ayr Street, Jamestown. We are proud to partner with local and State government in beautifying significant areas through councils’ streetscaping initiatives.

Work includes undergrounding existing overhead powerlines and the removal of Stobie poles. The Department of Infrastructure and Transport, responsible for public lighting on main roads, will install new energy efficient LED lighting.

How this affects you

The work will take place between 7am and 5pm, Monday to Friday. The civil work phase will start in September, followed by cable installation, then removal of Stobie poles. We anticipate that all the work will be completed by April next year.

To ensure the safety of our workers and the community, traffic safety management measures will be implemented along Ayr Street. We will maintain access to businesses using road plates and stop/go traffic management. Speed restrictions and parking limitations will also be in effect in the vicinity of the works.

There may be intermittent restrictions to driveway access throughout. Our crews and traffic management team will work closely with those affected to minimise any inconvenience.

Some private electricity connections may need to be altered as part of the project. There is no cost to customers for this work, and we will let you know in advance if this affects you and your property. Work hours and dates may vary due to weather conditions or unforeseen events outside of our control.

Power outages

Some customers will experience power outages during this work. If your property will be affected, we send SMS/emails to subscribed customers, typically two weeks before the planned outage. We send cards to those not subscribed however there may be delays with the postal service. If you do not already receive free SMS/email updates about your power, you can sign up for outage alerts via our website or call us for assistance. You need the National Meter Identifier (NMI) from your electricity bill to subscribe.


There may be some noise, dust and vibration associated with the work from excavation equipment and other heavy vehicles, however our crews will reduce disruption as much as possible. We apologise for any inconvenience and thank you for your cooperation during this essential work.
