We need to continually operate, maintain and develop New Zealand's transmission network - the National Grid - to ensure we meet the ongoing electricity needs of New Zealanders.
We have several projects planned or underway in the Taranaki region to improve supply there. These include:
- decommissioning and removing our equipment from the existing New Plymouth substation (at Port Taranaki);
- constructing new 33 kV indoor switchgear at Carrington Street substation, enabling the connection of new 33 kV underground cables (owned by Powerco and connecting to their Moturoa zone substation);
- installing a new 220 kV/110 kV interconnecting transformer at Stratford substation and converting the existing 220 kV New Plymouth to Stratford transmission line to 110 kV operation; and
- replacing conductor on our Carrington Street to New Plymouth transmission line. This work will also consider:
- the extent to which some spans of the transmission lines near the Port may be economic to remove, given that New Plymouth will no longer be required as a Transpower site, and
- the potential for future development and associated supply requirements in the Port area precinct.
