This page provides information for our residential and business customers on network pricing. 

MainPower provides distribution line services (poles and wires which deliver electricity to homes and businesses) to a population of over 65,000 people in the North Canterbury and Kaikoura region. Approximately 76% of our customer base is residential, with the majority of the remaining being small commercial, farming or irrigation customers.

We consult with our customers on an annual basis to gauge their general level of satisfaction with the distribution services we provide, as well as on price and quality expectations. 

MainPower generally performs well in terms of both reliability and quality of supply. Our customers also tell us that they would definitely not be willing to accept poorer levels of power quality and reliability in exchange for a lower price or discount.

What am I paying for?

MainPower does not bill customers direct for distribution lines services. Instead, we charge electricity retailers for the delivery of electricity over the MainPower network. Electricity retailers determine how to allocate this cost, together with energy, metering and other retail costs, when setting the retail prices that appear on customers’ electricity bills. According to the Electricity Authority website, around 26% of your electricity bill goes to paying costs involved in the local distribution of electricity.

What's changing?

There will be no change to overall network charges at 1 April 2018.

Network charges are made up of transmission charges (Transpower) and distribution line charges (MainPower).

The transmission portion of the network charge will reduce from 1 April 2018.

The distribution portion of the network charge will increase from 1 April 2018. The increase is to ensure that MainPower can continue to invest in making the electricity distribution network more resilient as well as to accommodate future growth.

The increase in distribution line charge will match the transmission decrease, so there will be no overall change in the network charge.

What about the rebate?

MainPower’s preference shareholders (also known as rebate shareholders or qualifying customers) will continue to receive a monthly rebate credited to their electricity account. Once a customer is connected to the MainPower network, they become a preference shareholder. Customers previously connected to the Kaiapoi Electricity Network are not deemed qualifying customers under the Trust Deed. 

At 1 April 2018, the qualifying customer rebate will remain at 2.014 cents per unit.
