Officially opened by the Minister of Energy and Resources Hon Simon Bridges, the completion of the 220 kV Hobson Street substation marks another milestone in a large programme of work to ensure a reliable power supply to Auckland and further north.
The Hobson Street substation houses both Vector and Transpower substations which provide electricity to the Auckland CBD. As part of this project, both substations were upgraded to provide greater capacity and resilience to the Auckland region.
Transpower’s Chief Executive Patrick Strange said that the construction of the project was challenging largely due to the compressed urban area in which a new tunnel and four buildings were built to house both the Transpower and Vector substations.
"With over 120 people working on this small site at any one time, construction was a logistical as well as a safety challenge. It’s down to the project teams who worked on the site, and the close and collaborative working relationship between Transpower and Vector that has enabled a safe and successful commissioning of the new substation for the benefit of our common customers."
"Importantly, the project also came in on time, and on budget," he said.
Vector's Chief Executive Simon Mackenzie says the joint project puts in place key foundations for future growth in the Auckland region.
"Auckland's role as New Zealand's principal city is being tipped to strengthen even further in the next 20 years.
"This project means we have the infrastructure in place to deal with a projected population of almost two million people by 2031. The Hobson Street substation ensures additional network resilience, along with extra capacity and security of supply for both the CBD and North Shore," he said.
The Hobson Street substation will connect to Transpower's larger North Auckland and Northland project, due for completion early next year, which creates a transmission ring around Auckland and across the Harbour Bridge to supply electricity further north.
