Smith Street Zone Substation Upgrade

When will work happen?

We are taking a staged approach for this project, and enabling works began in July 2024. From this point onwards until the remainder of the project in mid-2025, the footpath immediately outside the substation will be closed. Infrastructure projects like this take time to complete, and we expect all work to be completed mid-2025.

Some traffic management will be required in the area at times, and affected customers will be informed of any significant disruptions to traffic by a letter from the traffic management provider.

Smith Street to Willowbank cable intertie project

This project follows on from the Smith Street to Willowbank cable intertie project, which took place from mid-2023 to mid-2204.

During this project, we installed 2.5km of ducting to prepare for the hauling of a new 33 kV underground electricity cable across Central Dunedin, which will take place in early 2025. The cable will run from Smith Street zone substation towards North Dunedin, to the Willowbank zone substation on Great King Street.

This will form part of a ring network to improve the security of electricity supply by providing back-up options for 5,900 customers supplied by the two substations. You can find out more information on this project here.
