Overview

We are installing a new underground 220 kV cable circuit from Pakuranga to Albany, connecting through Penrose substation and new substations at Hobson Street and Wairau Road.

The new circuit will help reinforce electricity supply in North Auckland and Northland. They rely on one transmission line between Otahuhu and Henderson for their power.

We will bury the new cable primarily underneath existing roads and within designated transmission corridors, and remove an overhead transmission line between Pakuranga and Penrose.
