As part of its North Auckland and Northland (NAaN) Project, Transpower is installing an underground 220 kV cable connection between Pakuranga and Penrose, to provide more security to Auckland Central. The project will link at the Pakuranga end with the North Island Grid Upgrade project (a new transmission link between Whakamaru and Pakuranga).
This is a long-term solution providing sufficient capacity for the foreseeable future.
Tendering for this project (if any) will be made through either the GETS or Transpower website. Register at both these sites to be notified of any open tender release.
