Lumsden Substation Project
Expanding the transmission network into the Oreti Valley
The Lumsden 33/11kV Substation in Northern Southland underwent a significant upgrade as part of a broader initiative to extend the 66kV transmission network into the Oreti Valley. This upgrade was vital to enhancing the region's electrical infrastructure, ensuring it could meet increasing demands and provide a more reliable power supply.
The key aspect of the upgrade was the construction of a new substation at Lumsden, designed as an extension of the original site. This modernization increased the substation's capacity and improved the reliability of the local network.
The final phase of this major project was completed in September 2019, when the Oreti Valley 66kV ring network was closed, creating a critical 66kV supply connection from Mossburn CB322. This marked a significant milestone in the region’s electrical infrastructure development

In December 2018, Stage 1 of the project was successfully completed with the commissioning of the new 66/11kV supply. By June 2019, Stage 2 was finished, which included the installation of a T3 66/33kV transformer and the provision of a 33kV supply from Lumsden to the Riversdale area.
