MainPower issues reward to stop copper thefts

A dramatic rise in copper thefts from power poles has prompted North Canterbury lines company MainPower to take a firm stance, including offering a $5,000.00 reward for significant information relating to the tampering with or theft of copper earthing wires.

MainPower Chief Executive Sean Horgan says the company has seen a large number of copper earthing wires cut and stolen from power poles across the electricity network since the beginning of the year.

“We have experienced more than 200 thefts this year alone. The growing number of incidents is putting pressure on our resources and costing our community a lot in replacement and operational time.

“Not only are the thefts expensive and disruptive for our customers, it’s also incredibly dangerous. The earth wires play a critical role in maintaining a safe and stable electricity system and their removal compromises an important safety mechanism.

“We estimate the opportunity cost to MainPower to repair thefts so far this year at more than $1million. That money would be much better spent on upgrading the MainPower electricity network or supporting the communities of North Canterbury. As a community-trust owned business, copper theft is costing every power consumer in the region.”

Mr Horgan says the lines company is taking the unusual step of offering a reward for information given the safety concerns, the cost of replacement and the immediate need to curb the activity and encourages anyone with significant information to call 0800 WIRETHEFT to report it.

“The value of the copper being stolen is low in the grand scheme of things. Copper currently sells for around $14 – $17 per kg, and each theft nets very little. To gain a few dollars, the individuals engaging in these high-risk criminal activities are putting our communities at risk of injury or even loss of life.

“These thefts undermine the safety and reliability of the network and reduce confidence in essential infrastructure our communities rely on. Therefore, we are putting up a reward of $5,000.00.”

A community safety risk

Copper earthing wires are a safety feature. If there is a fault on a power pole, an earth wire will direct electricity safely into the ground. When earth wires are cut or stolen, there is a risk of electric shock, burns or fire, as well as the risk associated with removing an important safety feature from power poles.

“When these materials are stolen, it not only compromises the integrity of our infrastructure but also puts our customers and the community at risk of electrical hazards,” Mr Horgan says.

“We are also working closely with a private investigator who is independently investigating incidents of copper theft.”

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.
