We’re strengthening our electricity network in Selwyn.
We've completed work to replace the existing overhead power line between the Norwood Zone Substation to the Brookside Zone Substation to strengthen our electricity network.
Selwyn is a rapidly growing area, and this work plays a key role to make sure our network is future-ready and prepared for increasing demand.
Thank you to the community for their patience and understanding while we completed this essential work.
There may be some day long outages in December or the New Year as we prepare the line for commissioning. We will let anyone affected by these outages know ahead of time.
Installing the new poles and 66kV line
Orion and Transpower have recently completed a new 220/66kV Grid Exit Point (GXP) at Norwood. The new 66kV line makes use of the additional capacity introduced by the new GXP and strengthen our network between Norwood and Brookside.
This upgraded included:
Replacing existing power poles for larger poles that are spaced further apart.
Have additional asset on the poles to accommodate 66kV lines and 11kV lines. See photographs below.
Installing two 30m steel poles across the Selwyn River.
Before After
Power pole without upgrades
Upgraded pole with 66kV line
