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.
The work to decommission and remove our equipment from the New Plymouth substation will initially see a temporary connection of our two lines just outside the Port. Longer term we will be moving that connection to a point just south of the Tank Farm.
