Southbrook Substation Upgrade

Overview: Rangiora and the surrounding area is experiencing significant growth through new subdivisions and businesses. Southbrook zone substation, which supplies this region, currently operates at 33kV. This project upgrades the substation to a higher capacity 66kV/11kV 40MVA zone substation. This also improves operational capability with neighbouring zone substations and improves the Southbrook site’s resilience.
