Overview
We are constructing and installing new AC/DC converter equipment at Benmore (South Island) and Haywards (North Island) substations to increase the capacity of the high voltage direct current (HVDC) inter-island link.
The new converter equipment, known as Pole 3, will replace the 45-year old Pole 1 equipment at both substations with state-of-the-art thyristor valve units - similar to the existing Pole 2. The HVDC Pole 3 project, worth up to $672 million, will be completed in two stages resulting in an increase in the capacity of the overall HVDC link to 1000 MW from 2012 and 1200 MW from 2014.
