Purpose
Electricity transmission for the purposes of conveying electricity to the Auckland CBD.
The construction, operation and maintenance of:
a. An underground tunnel from Transpower New Zealand Limited’s (“Transpower”) existing substation at Gavin Street, Penrose, to Vector Limited’s (“Vector”) existing substations at Liverpool Street and Hobson Street for the purpose of conveying electricity to the Auckland Central Business District (“CBD”), together with all ancillary and related infrastructure including portals and ventilation fans. The tunnel will contain electric cables, with a maximum anticipated capacity of three 220kV circuits of 500MVA each and ancillary equipment;
b. Electric cables contained within the tunnel. It is initially proposed to install two circuits of 110kV circuits at 230MVA each, and ancillary equipment. It is intended to upgrade the electricity supply carried through the tunnel over the next 10-20 years in response to load growth and other alterations to the network. It is anticipated that any future upgrades will result in a maximum capacity of three 220kV circuits at 500MVA each and ancillary equipment; and
c. The construction and operation of a building containing 110kV and future 220kV gas insulated switch gear and three future 220/110kV transformers at an extension to Vector’s Liverpool substation site.
