North Canterbury residents receive share of $9.7 million rebate

North Canterbury electricity customers received a share of a $9.7 million rebate on their lines charges during the 2018-19 financial year.

Lines charges make up approximately 27% of an electricity bill and are charged via retailers, based on the customer’s power usage.

The rebate is passed onto all retailers on the MainPower network through our invoicing of lines charges and is generally shown as a discount on customers’ monthly power bills, however some retailers have recently stopped showing this as a separate item on their invoices and are instead showing bundled charges.

MainPower Chief Executive Andy Lester said “We’ve had some customers get in touch, concerned that their MainPower rebate had disappeared from the power bill they receive from some retailers. We want to reassure our shareholders that their rebates are still being deducted from their power bill each month, as usual. Ideally we would like all retailers to show the MainPower rebates on the bill each month, however unfortunately it is ultimately the retailer’s decision how they structure their invoices to their customers”

Electricity Authority figures show that the average household uses around 7,000 kWh per year. A MainPower customer using around 7,000 kWh per year would have received around $421.00 in rebates.

If customers are interested to know the exact amount they have received as a rebate, they can check with their electricity retailer.

Lines charges are used to cover the costs of maintaining around $270 million dollars of assets in the North Canterbury electricity distribution network, enabling MainPower to provide a safe and reliable supply of electricity to this growing region.

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.
