Upcoming Smarts Road outages

As part of our drive to provide safe, secure and reliable electricity supply to the North Canterbury region, MainPower is undertaking comprehensive work on Smarts Road.

What are we doing?

We are erecting new poles along the length of Smarts Road in preparation for running a high voltage cable from across the Ashley Rakahuri River to Rangiora Woodend Road.

This upgrade will provide additional capacity and supply for the rapidly growing Woodend / Ravenswood / Pegasus area, eliminating the need for any possible future load control and reducing the risk of unexpected outages.

Why do we have to turn the power off?

A key part of this project is raising a high voltage line along the length of the Smarts Road, which we cannot do while the existing line is live. To carry out the work we need to turn the electricity off during the day, from 8am to 5pm.

As we progress along the road, we will be able to liven the areas that have already been completed. This means that some customers will experience fewer days without power than others.

Key information

At this stage, some properties will be without power for up to nine days, from Monday 1 September to Thursday 11 September. 

We will not be working over the weekend so normal power will be restored from 5pm on Friday 5 September to 8am on Monday 8 September.

Hot water load testing under way ahead of winter

Until mid‑April, we’re working closely with retailers to carry out hot water load testing as we prepare our network for the coming winter season.

These tests run for a couple of hours each day, Monday to Friday, with no testing taking place over weekends. Because each test window is relatively short, customers are unlikely to notice any changes to their hot water supply.

The purpose of this work is to help us better understand how much controllable load is available during the summer months. Gaining accurate insights now means we can model customer savings more effectively by reducing system load at peak times. It also helps us assess whether this load flexibility could assist Transpower in deferring an upcoming local transmission upgrade.

This testing is an important part of ensuring a resilient, efficient network that supports our community.
